I am working with Jonas on this project as well. I successfully installed machine kit on the BeagleBone with a CRAMPS cape attached. I was able to get into the desktop environment of the beaglebone and launch the machinekit "Mendel Max CRAMPS" setup. I got into the GUI AXIS, and was able to turn machine on/off trigger the E-steps on/off etc., but when I went to do a test move of the machine by using the jogging commands in the GUI of AXIS the stepper motor would not turn. In the software the preview of the machine would move exactly like it was supposed to but the stepper would not move. I swapped out the stepper motor to make sure that wasn't the issue, and it was not. What could be causing this? I tried to scrub through the .ini and .hal files for stepper driver configuration but was not able to find it. Also is there a better machinekit config out there for the CRAMPS board for us with a CNC? I have no problem using the Mendel Max setup, it is just geared towards a 3D printer, and I wasn't sure if there would be a better option already configured. Thank you for any help you can provide. , On Thursday, February 21, 2019 at 10:31:53 PM UTC-5, jonas hauptman wrote: > > Hi, > > We are new to your group and to machine kit but hoping the community might > have some feedback for us.
