Stepper overheating

Good morning,

After assembling the machine 4AXIS we detected that the DHlinear engine was overheating, connections were checked and everything seems correct the only thing we have detected, in the settings as amperage max for one of the stepper motors is 2,8 instead of 4,8 which is set for the other stepper.

We have tried to change it in the configuration and save the changes but these are not saved correctly making even without being manufacturing or without being in motion the stepper gets hot; also We have tried to uninstall the software and reinstall it but that same configuration saved on the machine and as soon as we connect it to the PC the amperage is fixed with the previous values, without saving the modifications. We don’t know what else to try. We don’t know if it is possible to reset the controller configuration.


We would appreciate some help to solve the problem and be able to use the machine because even searching in the forum we have not found anything similar.

  • Can you set the Carriage and Mandrel Stepper Motors amperage at 2.8amps and the DH Linear and DH Rotary stepper motors amperage at 1.8 amps ?
