What about endstops? On v.1.2 i see only X-endstop. What about YZ?

This model is obsolete... And I don't think that nema14 have enough torque to drive the printer

Hey there.... it is not possible to generate accurate parts via OpenJSCAD for Nema14 and wood thickness of 24mm. There are solids in the space where the wood should fit in the MotorXY holders...can anyone help?

This seems fairly awesome. How are your prints? Any sense what your BoM cost was?

Hi, The BOM is missing at least the Endstop Switches and a Fan for the Hotend right?

hi thk u for the design. can u help me with v1.2, there is a problem with z slide part, if u use z rod 10mm there is a hole on the lm10uu holder and there is no stability for the part.

the STL outputs are not usable with 8mm rods, non manifold -> slic3r can't do anything with them...

12mm prints fine for 11.8mm wood.

I happen to have wood that is 11.80mm. However the openjscad script rounds down to 11mm. May it be possible to adjust the script to accept 0.xx values for the wood frame? I guess printing with 12mm might fit aswell, taking an extruders deviation into account but it would be really nice to see 0.xx values being accepted by the script. Thanks

hi. Beautiful design. Just a tough. Why don't code an option for GT2.5 belts and a screwless Z rod? Cheers and Keep up the good mood

The sensor mentioned in the BOM ( LJ18A3-8-Z/BX) is an inductive sensor, so do you not need a metal bed for it to work ? All the pictures I see use a glass bed.

Hello Serge, now smartcore v1.2.JSCAD works perfectly in OPenJSCAD ! Marc

updated smartcore v1.2 . now it works in openjscad.org. I wonder if it will work again here ? preview dows nothing right now.

If you edit smartcore-v1.2.jscad, and change in line 525 "grey" by 3 number with a "," in between ( e.g. (1,1,1 ) instead of ( "GREY"° and save it , it works fine in OpenJScad

Is there any file I can print so I can add two sets of Z supports using the gt2 belt instead of the threaded rod solution on prev iterations?

I opened Smartcore V1.0.1 in openJscad and in the menu, I selected Box wood thickness ; 12mm , X Y Rods : 8mm and Z threaded rods: true. So far so good. How do you now generate the separate STL's so I can slice them in Slic3r and print them? Many thanks in advance for the feedback

If you have error like this return this.color.join("/"); TypeError: undefined is not a function you can find in the source (smartcore-v1.2.jscad) the string .setColor("grey") and change it, for example, to .setColor(0.8,0.8,0.8) OpenJSCAD currently doesn't support setColor by name: https://github.com/Spiritdude/OpenJSCAD.org/wiki/User-Guide#color

Hi! Thanks for the great design! I've already printed most of the parts for it and finished the box.I've found most of the glitches mentioned here, but one - induction sensor mount. It appears to me that it doesn't have back part (half of the ring). Where do I find the other part of it? Also I couldn't find a fan duct in the JSCAD.I have to check everything before I take apart my other printer to take parts from it.

Hi smartfriendz!I've printed almost all the parts (generated from JSCAD for 8mm rods) and noticed some bugs already mentioned here. On the other hand, I think, there is something wrong with the inductive sensor mount - it is missing a part holding it from behind. I mean the mounting ring isn't full, just half of it is present. How can I generate this part?Also, I didn't find a fan shroud stl for cooling the printed part.I need to be sure that everything is safe and sound before migrating hardware and electronics from my Prusa i2 to new printer.

Actually, now that i look at it more carefully, I can see that the rod that goes fore and aft is not intended to be structural, however the movement of the bearings can cause the rod to slip.  Should it be set in place by a set screw?

I love this design! I am planning on using it to teach teenagers about building and 3d printers in general.I would like to make a recommendation. The plastic parts at the rod ends should have the rod end completely enclosed. This allows us to use the rod as a strong mechanical component which fights the tension of the belt. otherwise, the rod will try to slip through the plastic ends into the motor pulley area. I'm looking at the Openjscad version 1.2.3.Also, I get "WARNING: Ignoring unknown function 'polygon'." with Openscad 2015-03

I am currently printing parts for my Smartcore.  I just printed the head block v1.2.  The top has two areas for bearings, when setting X rod size to 8mm, the length of these areas do no fit the standard LM8UU bearings I have.  Is this a known issue?  Any way to work around besides filing out the ridges?  Thanks for the great design!

@smartfriendzI love the project and I am currently in preparation of building one myself.I believe I found a couple of bugs in the new v1.2 JCAD file when creating a custom version:1. When using a 'Box wood thickness' greater than 15, the '// xtra save material' option for the 'bearingsXY' part will generate the hole so, that it is breaking the part.--> workaround is to comment line 582 in the JSCAD file like this:// xtra save material       //cylinder({r:_XYrodsDiam,h:Y,fn:_globalResolution}).rotateX(-90).translate([27,0,20]),You will now lose the hole of course, but the print will be much stronger.2. When exporting the 'parts only' stl file, the 'motorXY' parts are not included.--> this can be fixed by adding the following lines (lines 1281 and 1282 from case 1 = 'all printer assembly' view) beneath line 1347:motorXY().translate([-_globalWidth/2,-_globalDepth/2,_globalHeight-20]).setColor(0.3,0.9,0.3),motorXY().mirroredX().translate([_globalWidth/2,-_globalDepth/2,_globalHeight-20]).setColor(0.3,0.9,0.3),Both lines were missing in v1.2 so the 'motorXY' parts were not rendered in the 'parts only' view (= case 3).Keep up the good work!

WOW. I just realize that V 1.2 has different "rear" bearings support...This will be the last question (almost for a week ;) !!!): I have print:- Z axis complete (V1.01) - Bearings xy (V1.01)- Slide Y (V1.01) Tomorrow i'm going to print: - motor (V1.01) - head (V1.2) - extruder (A modified version by BrunoBellamy) Mixing HEAD v1.2 and motor, bearing, slide y of v1.01 is correct ? Thanks !

your settings are right.. it's a design problem. If you watch good, you will see that the bearings support go wider when we insert bearings, then it's perfectly normal it bends the middle part ( unfortunately for the design..it's a fault , or a bug ) . I intend to update to a flat U for the right part . Then we will have an iso system. The left part constraints to 1 degre ( Z slide only ) and the right part would constraint to Z rotation only. This way, we don't have this extra constraint of the distance between the two rods. I just did this for hte head part and the two X rods. The top is now free to move verticaly,  that limits problems from extra constraint ( distance between two rods that must be the same in three separated parts ). Well..globaly, i need to rework this part . There's an update coming :  L and R written on parts to easy recognize left and right, new inductive support , a little more solid and a few adjustments .. nothing new for Z.

Hi @smartfriendz, infact i havn't problem to print but with printed object.After i print it, i try to insert the bearings (10 mm into z carriage) into Z slide version 1.0.1, and the support start carving. Maybe is my print settings wrong (about 1 mm shell with 45% fill), or it's ok, and i just need to fix the wood table on z slide ...I will try the french formum, if the talk english as i don't know french.

@<a rel="nofollow" target="_blank" href="https://www.youmagine.com/users/fbolzoni">FBolzoni</a> : We didn't had so much problems printing those parts ? all the supports are made with 45 degres angle under to be able to print without support.  about the forum, we have one you can find from smartfriendz.com ( link on top ) , you will see mostly french but everyone speaek english there . Also, there is a smartrap forum in reprap.org with a few makers working there .

@<a href="https://www.youmagine.com/users/fbolzoni" target="_blank" rel="nofollow">FBolzoni</a> I've printed the Z-Axis with 8 mm and getting the same problem. But this problem is the same with the previous version, i.e. not new.But I had big problems with printing it because of the belt attachment kept on getting to high after printing the overhang for the second part. After rotating the part 90 degrees I got it printed. But with pure result. I think there are ground for a re-design of this part.

Here we are again !I've printed the whole Z-Axis with 10 mm diameter. Tryed to push the bearing and all the piece start carving ... After insert all the bearing the plate support aren't parallel anymore and look like the want touch togheter.Is this normal, is my print wrong, or what else ?ThanksPS: There is a forum where put question and read already ansered one ?

Hi, It is made on purpose : - the head top is constraining the 2 top bearings on only one axis rotation  ( around X axis) . We noticed when printing 3 parts (Yslides and Head) , you willnever have a perfect alignment beetween rods,so the bearings on the X axis will force . With this design, the two top bearings can be adjusted to the good rods distance.- about the proxysensor, we are now re-using the nuts , so a half is enough to fix it ( note it's a liiitle smal actually and will be extended, but not to the full circle.  What is not made for now , is the 8 , 10 mm options for rods ( I need a second design pass to extend the supports) . That will come very soon now .

Hi all.I see the new version, but i think the new head isn't complete: top bearing are free for more than 50% on top and the proxysensor holder isn't close.It's a mistake or they are intended to be like that ?And, is possible as i'm not able to do modify for 10 mm rod bar also for xy axis ?

Sorry for ignorance, but for the z-slide on a lead screwx2 setup the stl appears to be hex, but everything I find uses a round leadscrew nut. Can someone set me straight?

Hi. Is possible use xy rods with 10 mm diameter ?It's so easy as put 10 into openJSCAD parameter ?Answer: No. with rod at 10mm the hole into printerhead dosn't come out ... Any planned fix ? Fix #2: I think i have found where there was the error: a line like this     if(_XYrodsDiam==10){_XYlmDiam = 19;} was missing.I added two lines, one for 10 and one for 12, as the Z axis and llok like it's ok.If someone can check this i start printing ! Thanks

I was just reading the BOM & it mentions a Pressfit 2 x 4mm with M6 thread. Is this something to do with the extruder? If not, could someone tell me what this is please (hopefully with a link or a picture of one). Thanks in advance. Nevermind, found it.. DOH!

Will definitely try your pins out for something though - working on a larger version of Richrap's Sli3dr in the margins and could be useful there...

<a rel="nofollow" target="_blank" href="/users/djinn5150" class="mentioned-user">@djinn5150</a> Thanks, I like what you did there and I'd probably use that z setup if the main model hasn't been fixed by the time I start printing parts. May I ask what was so "heavy duty" about your design? I'm thinking of using 8mm throughout and 18mm MDF for the box to really give some inertial mass and damp any vibrations.You mentioned that yours is going really fast - please could you give me an idea of what speed, accn and jerk settings you're using and still getting prints you're happy with? What steppers and drivers do you use to achieve those speeds? Again, I might have missed something obvious, but what firmware are people running on this? My first port of call would be the coreXY setting in Marlin for RAMPS but I'm just guessing.EDIT: I found this after searching. <a rel="nofollow" target="_blank" href="https://github.com/smartfriendz/smartcore">https://github.com/smartfriendz/smartcore</a> Sorry for bothering with that question. RAMPS 1.4 is mentioned in the BOM, so now I at least know the software and controller side.

<a rel="nofollow" target="_blank" href="/users/street" class="mentioned-user">@street </a>  It does not look like the threaded z has been fixed yet but, I have a re-work that is working really well you can find that <a rel="nofollow" target="_blank" href="https://www.youmagine.com/designs/smartrapcore-heavy-duty-z">https://www.youmagine.com/designs/smartrapcore-heavy-duty-z</a>.  As for the extruder I opted to use wades so I can neither confirm nor deny if the MK8 will work.  I am currently working on a part cooling fan solution to mount around the backside of the X rods but It will be designed with the extra room I built into my printer so not sure if it will carry through to the "official"

I really like this - is there a way to make it compatible with e3d v6 / Lite6 hotends and has anyone built a cooling fan for the print (as opposed to the hotend heat exchanger)? Secondly, I read the comments about threaded rod z axis and wondered if this has been fixed in the openjscad model yet. Finally, could someone confirm if you can use a Mk 8 extruder gear with the current openjscad options? Thanks for helping and sorry if I've missed an obvious answer to my questions!

oops , sorry Mateus :) I think i was tired when i posted that , i know perfectly it's you who made this update .Eventually, i will mix it in here of course. It's a very great addition !  It's just that the production of smartrapcores takes us all our time lately, so i didn't have time to work on the model .Soon to come a new option for MK8 for the extruder ( this is what we sell now) and  double pressfit to be more easy to put the filament under the extruder ( it's quiet hard to find now ) . Some accessories too : - support for filament roll inside the box- box for ramps and support for LCD.

<a rel="nofollow" target="_blank" href="/users/djinn5150" class="mentioned-user">@djinn5150</a>  thanks for posting that, I didn't had a chance and hoped that smartfriendz would merge my fix to it. However I agree with smartfriendz, that pull request should be fine reviewed (if time allows) I try to post threaded rods design in youmagine with github link - it needs some love ;) it loses a lot z height.

For the record, it wasn't me that designed the original threaded Z, it was @Mateusz P if I am not mistaken, and is his fix that is included in my github fork, but I did publish a heavy duty z here on youmagine that is based heavily off that design.

Hi Rein,sorry for the missing update.  The threaded Z part will be removed for a little time because I integrated a little too fast this mod by dhinn ( wich is very nice mod by the way ) and i had some problems with the main model.I will first re-publish a cleaned version and then re integrate. In the meantime, he indeed made a fork and published the mod on his repo, so you can use this one.thank you

I agree it's not really wonderful, but think the rod will come right on top of the steppers , so this thin wall shouldn't be a problem.To make it more "clean", I need to put the road in front of the stepper and this will change the all structure ( size of wood box, slideY,bearingsXY..etc). It will be done, but i need a little time.thank you

I've been wondering: The bearing obviously goes in the center, but it looks like some kind of rod goes through the bearing and sits on the notches to the side.  What do I use for that?Part: <a rel="nofollow" target="_blank" href="https://drive.google.com/file/d/0By3FkNAUMV8VOGFVbDh3VmNadGc/view?usp=sharing">https://drive.google.com/file/d/0By3FkNAUMV8VOGFVbDh3VmNadGc/view?usp=sharing</a>

FWIW, I have found that you must log out/in on Youmagine for things to update for some reason.   Now that I have had this printer running for a few days I must say I LOVE THIS PRINTER, just when I think I cant push it any faster it takes more and just keeps going,  I really need to work on my acceleration/jerk settings and see just what this thing can do.

still not updated, sorry. I was late because of the production. I will clean up the file to have stilll threaded Z , but I need to recalculate all this part ( actually it's not wrong but bad positioned).The print width/height gives the real print diimensions. To see the  rods / wood/ belt dimansions, please choose the option " walls and rod sizes"

djinn5150

almost 10 years

If u edit the file in jscad there are parameters to enter based on your specific build, enter your rod length minus the numbers I specified in the build volume, select wall and rod sizes then update that will give you wall and rod sizes if rod size matches yours your golden. Make sense?

Rein

almost 10 years

So the print width/height/depth are just the rod length, not the actual print size?  Then how do I get the actual measurements to cut the board from there?

Cheers djinn5150, I 'll check it out.

Rein rods are (55,65,110){X,Y,Z} over build volume, so if you have the rod length set your build volume accordingly in the jscad file and select wall and rod sizes to get a calculated board size.

I am gonna have to really check mine now, I am using 5/16 rod as well :D I will def check out your pull, want to avoid reprinting the z for a 3'rd time now lol Sounds like your pretty fluent in jscad, have any advice for a greenhorn coming from openscad? I just cant seem to get my mind wrapped around it, I think its the javascript that is throwing me for a loop.

Mateusz P

I use 5/16 rod which is around 8mm, but this doesn't matter what happens is top end of z-axis (one with bearing) is 1mm to deep, and threaded rod is not parallel to slide rods. It seems like 1mm difference but I updated design - created pull request for it. I also added and z assembly view, with  threaded rod that shows it is in center now. <a rel="nofollow" target="_blank" href="https://github.com/smartfriendz/smartcore/pull/7">https://github.com/smartfriendz/smartcore/pull/7</a>

Threaded rodz Z option is bugged - carriage for Z needs the nut hole moved back 2mm. I will update file and create pull request tomorrow. just build one z axis and found that out.

Really liking the new update, think I will go ahead and run the threaded Z parts, but Is it just using a pretty standard M8 threaded rod and a 608zz bearing for the top? Just guessing off eyeballing the upper bearing size.

ok djinn , most of parameters where in "int" type. It means it didn't take account of decimals. I wouldn't think about tickness with decimals.. I will update .

Is it just me or is the jscad dropping fractional sizes in board thickness? I.E. If I build for 12mm wall sizes are the same as if I build for 12.8. After completing my frame it became apparent the wood I purchased this go round was a bit thicker then the scrap I test fit my printed motor and bearing mounts too, after a re-print with recalculated board thickness the parts are same size, roughly 12mm +/- .05. I think i am just going to router my frame down to fit 12mm, but curious if my observations are correct.

which gear do you use in extruder?

Mateusz P

for belt calculation I used: ((XrodLength + beltXAddon)*4 + (YrodLength + beltYAddon)*4) where var beltXAddon = 120; // belt extra length over rod size - bearing guides and difference between bearing edge to end of rod var beltYAddon = 30; // belt extra length over y rod size - distance from motor pulley edge to Y rod mount and measured by eye -printing parts now to set on top of my frame and waiting for belt from ebay to validate the measurements

Unfortunately I think the head pieces will be the biggest challenge given the location of the belts/clamps.  I think I am just going to re-enforce my assembly with a bit of glue.  I am looking at the head design and thinking scalability for a dual extruder should be pretty good, I will play around with it, A belt length calculator would be a very welcome addition to the jscad file, wish I could help with that but I am horrible with scad. Other then those things I think 1.0.1 is going to be great,

smartfriendz

thank you djin.. you see all ! I've seen also the little support on the motorXY for 8mm , but with the stepper support , it will make it..for now ( even it's not really nice). The thing is, if we want something more clean, we need a deeper change in the design ( support going further, or the all plane XY higher). I think we will do but not immediately.

djinn5150

almost 10 years

Another note on MotorXY when using 8mm rods the support for the rod seems to be cut off almost at the bottom of the rod hole very little material to support rods on bottom. I can also confirm the screw hole issue on the "head" stl's they do in fact "hit". The "clamp" hole is fine, its the holes for the print head mount that could be an issue there is approx approx 4mm of material for screws to grab before hitting the linear bearing so it might be ok. I have printed but not assembled the head yet.<div> </div><div>*EDIT: Nevermind just dawned on me the motors will help support the rod, its to early not enough coffee and to little sleep :D</div>

you're right. This version is in heavy dev, so i didn't check all the options and more importantly, the generated plates are not updated. It will be all good in a few days as i'm happy with the actual design. Now i will start to clean all that .

I'm still working on it, but for now there will be only the option to export plates with all elements at once. I would need to hack the heml file on youmagine to export , for example, a zip with all separated elements . We'll see, maybe we can do that too ?
