Spindle Speed Calibration Procedure - Syil X3 Mill under Mach3 Control

Hi All Syil X3 Mill Users,

Syil X3 Mills are Seig X3 Mills converted to cnc.

At the attachment below you will find the procedure that I used to calibrate the spindle speed of my Syil converted X3 Mill. The procedure calibrates the speed requested by Mach3 to the actual speed of the machine.

I was always annoyed that I could never attain the maximum 3400 rpm under Mach3 control. The low end wasn't too bad as delivered but the top end was miles out.

I have now adjusted my machine following this procedure and I am now happy. Of course the calibration is for speed settings with no overrides.

Hope this helps for those who like myself wondered how to do this for 12 months.

I was lucky that my machine front panel speed display was quite accurate when checked with my laser optical tacho so I did not need to adjust this. If any one knows how to calibrate the front panel rpm readout, please let me know and I will amend the procedure below so others can benefit.

Kind Regards

Chrisjh
