I recently got a RUMBA board, I was wondering if people have had issues with it,
My main problems so far:
1. Random behaviour with the endstops triggering on and off
2. Completely unable to flash Arduino with Ribbon cables for a controller attached
3. very frequent connection errors with PrintRun
4. Steppers randomly increase or decrease speed
5. Arduino seems to randomly reset during operation.
I tested all individual parts with my Ramps 1.4, replaced USB cable, ribbons etc, the issues only appear for the RUMBA board
certainly the support forums for them seem to indicate issues and there is a single blog post that I can find:[coherent-reprap.blogspot.co.uk]
At this point I am requesting a refund and giving up on it, however it's frustrating as at first appearance it is a very nice board...
