Open loop stepper tuning

I have a question regarding (ioni / ionicube) regarding (stepper motor stalling).

My hardware configuration:
-(ioni pro)
-(stepper motor - SY85STH118-6004B)
-(1.6.1)
-(linuxcnc with mesa 5i25+7i76)

Problems arise when:
-stepper stalls around 450rpm. With old drives they would spin over 2000rpm

How it behaves:
-(describe system behavior)

How I would expect it to behave:
-(describe)

I have attached following files:
-(consider adding saved Granity configuration file .drc)
-(screenshots)

I also would like to share that (drives setup with suggested config for steppers).

Note: you can tag the best answer as solution. This helps others to find the solution to the same question.

Hi,

Could you please list also the power supply you are using? Thanks.

Hi Gmal

You can test the system with Granity also. Just scope the motor voltage and other relevant variables when you drive the motor with different setpoints.

Kind regards,
Esa
