Because the markdown seems not to be working please see https://www.thingiverse.com/thing:2423066 With a frame of 500x500x520 _mm_ has a build volume of 340x340x420 _mm_. [Detailed Album](https://goo.gl/photos/qsApEjMvLFL5nmS78) [Calibrating Print Video](https://youtu.be/aAFQqTjLlNw) [Lithography Video](https://youtu.be/9l1R5B3iknQ) The provided here gantry carriage is only for [OpenBuilds VSlot](http://www.vslot-europe.com/home/8-vslot-rail.html). Needed only 4 rails of OpenBuilds - the rest can be any [cheaper 2020 profiles](http://www.motedis.com/shop/Nutprofil/20-B-Typ-Nut-6/Aluprofil-20x20-B-Typ-Nut-6::1.html). Close to Spain [this one is perfect](http://www.makergal.es/g-slot). Take the columns 20 mm longer than the [screws](https://www.aliexpress.com/item/RepRap-3D-Printer-THSL-500-8D-T-type-stepper-motor-Lead-Screw-Dia-8MM-Thread-8mm/32509998654.html) to get the max of the vertical travel. The three screws need to be straight: if one does not roll fine on a flat surface then do not use it: [Pure Screw Z Stage](https://www.youtube.com/watch?v=nvwcWql0m2U) Mount the screws to the _lower_ rails, not like in my photo (to the upper rails). For the cross carriage take a [cheap but very good hotend](https://www.aliexpress.com/item/FreeShipping-Long-distance-3D-Printer-J-head-Hotend-for-1-75mm-3-0mm-E3D-Bowden-Extruder/2041826923.html): Dual [DeerArc](https://www.thingiverse.com/thing:2386804) or Solo [TurtleArc](https://www.thingiverse.com/thing:1914544) The file *TJoint2020.stl* needed if not using slot profiles for the Z stage, otherwise can use regular corner items and save on printing. The best, IMHO, open source extruder [SaintFlint](https://www.thingiverse.com/thing:979113) Except the extruder I print all my printer and robot parts wit a 0.8 nozzle out of PETG and the screenshots of the settings are provided.
