Hi,

I just finished building my G2S pro, and have a problem with the connection to extruder motor one. I'm pretty sure that the cable and the motor
itself is fine, because i tried to switch with the one from motor two and then i worked, so the problem is in some settings or in the connection on the board itself. What happens is when I activate the motor connected to the "Extruder one motor" socket on the board, it just buzz'es for the amount of time is was set to be running, but the drive wheel do not move.

I hope some one can help with a fix for this, because a "working" extruder one motor I'm pretty lost!

Hi,
Maybe it's the driver A4988 has a problem,check this post:

Hi,
why extruders when I start printing does not turn?
If I do the manual test with repetier engines work, but when no mold.
What should I set to make them work?
Thank you

You mean the two of them or one of them?
Maybe you can attach a video to show us?

Yep, that sounds like my G2 Pro times 2, both 1 and 2 extruder gave me problems, like would start to feed sometimes for a short time, then start skipping and all, could not find any data on the motors that came with it for the extrude motor 42HSC8402-15B11, but what someone found close to that number ended in -25 was not it. I have 2 other printers of the delta design and knew right away there was a few issues to address. As for that motor used, I finally replaced it with one I keep on the shelf as backup 17HS19-2004S1, now that fixed the problem with feed issues. Found the 12v 20 amp power supply was really underrated for the task, would have a 2 volt voltage sag at 10 amps, very unstable, replaced with a 12v 40 amp rated supply, the case is about an inch longer than the original power supply, plus comes with its own cooling fan, hooking the new power supply was the same as the original, but in reverse order, like right to left is left to right. Most the parts you can find on Amazon or E-bay and are great resources for 3D printing at this time, as for plastics, try micro center online, pricing is competitive, they have pla, petg, and abs for starts in many colors.
