Hi I am looking for help on my controller and stepper motors the board in the controller is the JP382-A and the steppers are the 57HD0401-15S 1.8Deg 2.0A these are Nema 23. The X & Y steppers are slipping and I can no longer use the machine it is less than a year old and the people I bought it off on ebay have told me that I will have to pay £90 for delivery from china for the two steppers. So can someone please tell me what the maximum amp output for the steppers are and is there any other steppers I can buy in Europe that will replace the steppers I have. Also what voltage are these motors
