If its a heat issue, the fan needs to be blowing on the stepper driver, not the motor itself. Although if the motor is getting too hot, there might be too much current going to it and that needs to be calibrated correctly.
What type of board are you using? Some of them have greater heat dissipation issues, although in my opinion(not necessarily the general consensus), you should put a fan blo

General Mendel Topics
I'm having a lot of problems with my extruder extruding. I'm using a Greg wade extruder with a hobbed bolt. I'm having two problems back and forth for seemingly no reason. It basically boils down to not grabbing the filament and/or then stripping it. I'ts having a lot of problems actually pulling the filament in. I've rigged a hanger to hold the spool of filament basically right over the prin

So I think I figured out whats going on. When laying horizontal shells, it lays a fast loose layer then slow tight layers. Always in that order. That would make sense for top layers as the loose layer would be on the infill and covered by the outer layers. However, that loose layer on the bottom is is visible outside the model and the tighter better quality layers are on the inside of the mode

I'm using 1.2.9 and the slower speed I set for the first layer is instead used only on the second layer. I'm not really sure what's going on here. At first I though the first layer was a crappy interfacing layer, but even with that turned off, I'm still getting a fast, poor quality first layer. It then takes it time on the second layer. Anyone have any ideas?

I'm trying to find documentation on the physical pin locations on the rumba so I can do some customization within the marlin firmware. All the documentation on the reprapdiscount page is in the altium software formats and I only have diptrace so I'm unable to open them and not entirely sure what it entails. Any information, documentation, help, or advice would be appreciated.

Controllers
I'm converting a 3d Systems CubeX Trio to run with a rumba board running marlin with the minimum amount of hardware changes as possible. I have just about everything set up but I'm getting stuck trying to configure the z endstop. The CubeX Trio uses hall effect sensors to sense steel pieces on a predominately aluminum frame. The x and y axis work fine as the hall effect sensors and steel pieces

Firmware - mainstream and related support
the microprocessor resetting sounds like a power surge or voltage drop tripping built in surge protection on the board. An easy fix/test would be to make sure that the light and printer are plugged into outlets hooked up to separate breakers and making sure that the printer is plugged into a surge protector first.

Sanguino(lolu)
I've assembled my Prusa i3 and have been unable to melt the abs for printing due the sanguino incorrectly reading the hotend temperature. I'm currently using cura 13.11.2 and sprinter on my sanguinololu 1.3a with 104GT-2 Semitec thermistors. The hotbed and hotend begin to heat up when I start the print, however the heating curve read by cura does not follow the actual temperature of the hotend
