@kochmi: That should be the correct value to change, are you sure that you compiled and uploaded the firmware to the board? If you connect to the printer over USB and send a M503, what values does show under M92?

@Roland Benner: I have added a text suggesting using a reversed IRobertI feeder to fit the spool.

@reibuehl: It seems like F695 and MF695 bearings have the same outer dimensions, so they should work just fine. And yes, all pulleys should be with 5mm bore, i will add this to the BOM.

One more question: Would F695 ball bearings also work as MF695 seem to be very hard to source?

The GT2 pulleys are available in 5mm and 8mm bore versions. I assume both need to be 5mm versions, correct?

Hi Meduza, I built your feeder and it really works perfectly! How can I adjust the feedrate in the firmware? I tried to change (double) the value for "steps per mm" in Ultimaker2Marlin-16.03 firmware: #define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,200,564} Where 564 is the double value. This has absolutely NO effect. What do I do wrong? Thanks a lot for a short advice! Best regard Michael

Hi Meduza, this gearbox is really fantastic. I use 2 of them because of my dual head. The gearbox is 2cm high, to avoid collision with spools I had to swap left and right hand feeders. Load spring and lever open/close looking to outside now. That's amazing, because I found that the knurled relief on the filament is looking to inside of the bowden, tha t reduce the friction in the Bowden. Of course I had to reverse feeder in firmware. Thank you Roland
