have you added the ceramic cap to the 5v and ground at the encoder? the us digital units according to marris of gecko drives , do not have a bypass capacitor and can give an erratic output. i had problems with drive faults with the vipers that could not solve until adding the ceramic cap at the encoder. check out the gecko site. there is an instructional document for the fix of the us digital encoders. i have purchased some amt102 encoders with the line drivers  to replace them when i have time. the amt102 each with line driver cable were only about 40.00  .

not strange at all. i have mach running a back gage on my press brake. single axis. used 2 rolled ball screws mounted each end of the brake frame. attached to the ball nut is an angle  mount that is bolted to a 2x6x.188 rectangular aluminum extrusion.2 movable stops can slide the full length . brake is a hydraulic pearson 14'. 180 ton. i just created a simple screen with screen4 that has estop, reset, mdi window, gcode, and x axis.a few buttons like load gcode, rewind, close gcode. i have another dro for ram depth on the screen also but have not mounted a servo motor to the drive for that yet. it works very well, 10 years now. used to use turbocnc.

go back to the motor tuning screen where you entered the steps per inch. the next box is your max speed setting and the 2nd box is the acceleration to max speed.

hi all. has anyone added a button to the main screen to  make the jog speed slow to 50%? like click on the button and the dro for the jog speed would be set to 50%. another button to return to 100%. i change it often for manually parting off leftover sections of sheet with the plasma.
