Hi everyone
I purchased some nema 34 stepper motors, drivers and breakout boards for use on a 4x4 cnc router from a chinese company. I have some serious problems in the setup if anybody can possibly help. Support is now non existent from them and im stuck!
2 main problems, we cant get the e-stop and any limits to work,and the Z axis loses steps no matter what pulse setting I seem to try. Have got 2 identical breakout boards and they both act the same so maybe its something i have overlooked.
The motors say 3.5amp on them but the motor drawing says 5.6A/phase? The drivers they say were matched and are model SD-2H086MB.
Power supply is 48v, 10.4amp. The 2 Y axis motors are geared 1.5:1 and the Z axis motor is 1:1. The ballscrews are all 5mm pitch.
All technical docs are attached. Would greatly appreciate some guidance to maybe sort one problem at a time. Possibly discover why no limits etc are working. Maybe someone has had this board.
Thanks, Dougie
