Howdy!
I am trying to update the firmware on my Mini Rambo, but I have the 5/16 threaded rod instead of the T8 leadscrew, which the GitHub file is titled with. Will this work with my MPCNC or is there some other file or tweak? Also I do not have any endstops installed and was wondering if that would cause a problem with the new firmware.
You need to change the steps/mm at least. You may also want to reduce the max speed for Z.
Both of these parameters are in the Marlin/Configuration.h file. But they can also be changed through some gcode or through the LCD.
If you’re new to arduino, just follow the steps on the marlin firmware page with the T8 firmware. The Z will just move a lot less than it should. Then change the steps/mm.
