I recently built a Hictop 3DP-11-ATL, upon initial power on every stepper motor will move one direction then reverse for one second and endlessly repeat the process. All the heating elements begin to heat up and the cooling fans pulse in speed in relation to the intervals of the steppers...
The LCD does work and I have full access to the menu. I have tried disconnecting everything but a single motor but still have no luck
The control board is the MPX.3, I can't seem to find the firmware for this machine to attempt to reload it.
Any ideas? Thanks!
