I’ve finally set up the MPCNC and i’m having a really weird problem with the x axis stepper motors.
When I try to get the stepper motors to go in one direction, sometimes they do, sometimes they don’t, sometimes they just freeze (judder but move nowhere)
This does not appear to be based on travel speed.
When y and x are swapped on the ramps board, y works perfectly with either, x freaks out with either.
wiring is shown below.
it worked well enough to draw a small pen plotted butterfly earlier, so I don’t know what has changed (if anything).
- Did you buy everything from here- No everything was bought elsewhere.
a)If you didn’t or changed some things please don’t leave out any details and include what firmware you flashed. - Stock firmware for ramps +LCD
Are you using end stops?- No
a)If so please disconnect them.
Mac or PC? - PC,
Include a picture so obvious errors might be spotted. - see below
and a video of the control moving in only one direction:<source src="https://goo.gl/photos/B7VoS5kzWVugyic9A" />
(in case it doesn’t load) and I can’t include it
Anywas I’m really stumped on this. any ideas anyone?
