Question #: 13239

Question: I used DSP controller for my CNC machine. How can I determine why my CNC machine produce different output as per my requirement. example, i make a design size 10mm x30mm in my design software, now, why is it that my cnc output is15mm x 65 mm?

Current Solution

The DSP controller uses its own pulses per unit (in your case, it's pulses per mm). That number is he same as steps per mm (or steps per inch if you are using that unit). Make sure that the pulses per mm is configured correctly for the machine mechanical components and the mircistep setting on the driver for each axis.

Additional Information:
You will need to make sure the DSP's parameters match the specifications for motor tuning.
