In the meantime, here are some other related threads:
Previous solutions to similar problems have included:
- be sure that all the connectors are all the way secured and each wire going to the connectors aren’t loose
- check DIP switches on the motor drivers are fully seated (power off board before doing this)
- slightly increasing the current coming from the driver by rotating the potentiometer on the driver clockwise (power off board before doing this)
- if v-wheels are too tight and rails haven’t been cleaned on top and bottom then the gantry could snag on the debris on the rails - clean the rails and set your wheel appropriately
- loose wires to power connector causing power instability - reconnected the power connector to the line from the brick and check that the motor drivers are staying lit even when the box is shaken around
- checking all your grounds - whether it’s your dust collector, or running an extra ground from router all the way back to power source if the cable has nicks, cuts, or divots in it
- change to a different electrical circuit / relocate laptop / try another laptop / change USB cable
