No, it is fiberglass, but it looks like it sat somewhere very dirty and got wet or soaked with something so the fiberglass was falling apart. I bought the new board, checked the motors (with a ramps board), so I know that much is ok. I think the rc servo is ok or at least seems to work. There isn’t that much to this thing, I set the current (actually might need a little bit more), but the motors still seem to cog very hard like the board is sending full steps. I have checked the motor wiring by the elimination method so I am pretty sure its not that. Is it possible I have the wrong driver installed?

I assume it was one of the earliest models. The board was cracked along with the frame. I am now printing a frame from thingiverse to try to put these motors and the new board on because it is falling apart. I think the previous person got it from someone else too because it looks like these aren’t the original motors. I tried out the motors on a ramps 1.4 setup and they run smooth there, but seem to be running full step with the eggbot board. By the time I figure this out, I probably could have just bought the new kit. I should have the new frame printed in a couple hours and see what happens then.

Yes, I found a cold solder joint and resoldered it. Now the pen is working properly, but the motors are “jerky”, like very low resolution. Is there a setting for this?

no, it doesn’t respond at all

it is plugged into B1 with the brown wire toward the edge of the board.
