Hi folks,
I've made a custom repstrap and I encounter some recurring problem.
When printing, it sometime offsets the whole print both in Y and in X axis from a huge amount of steps.
It isn't a overheating problem since everything is cool (I put fan on each motor and on the driver and I can run a 3 hours print without problem which means the nominal temperature is cool enough).
It happens randomly, sometimes after 5 minutes, other times after 2 hours ...
I think it could be software related since I drip feed through USB.
I'm using a Megatronics V1.0 with Marlin and I've a spare LCD display so I could try to print in autonomous mode (would still need a keyboard).
what do you think ? (I'm adding a picture so you can see what is the problem)
