Hi, Recently I have build my first CNC based on Sphinx. For the controller I use Gecko G540. CAD software use Aspire, and MACH3 to run the G-Code I have strange result for my pocket operation. When I make pocket toolpath frrom aspire, for example i make 20mm pocket, the result is 19mm. When I try to make 10mm pocket, the result is 9mm. Any size I want to make, the result is 1mm smaller in X and Y. But when I make profile toolpath, the result is right. 20mm profile, will cut 20mm. Also for other size. Need a lot of advice here. Regards,
I'm not familiar with Aspire but I can tell you that the problem is with Aspire. It is possible that you have a setting that makes it smaller, like maybe it's only the rough cut and it expect a final, finish cut, which is many times 0.5mm (which is 1mm in total).
hi, for cutting (profile toolpath), it has no problem. the size is right. but when doing pocket toolpath, it have the problem. and aspire doesn't use rough cut & finish cut except for 3d object. for 2d pocket toolpath, it doesn't use rough cut & finish cut here is the gcode from the aspire T1M6 G17 G0Z20.000 G0X0.000Y0.000S7730M3 G0X9.148Y9.057Z5.000 G1Z-2.000F600.0 G1X12.638F1200.0 Y12.547 X9.148 Y9.057 G1X6.608Y6.517 G1X15.178 Y15.087 X6.608 Y6.517 G1X4.068Y3.977 G1X17.718 Y17.627 X4.068 Y3.977 G0Z5.000 G0Z20.000 G0X0.000Y0.000 M30
