Circle cut in half. #1199

Closed LvWDF closed 1 year ago

LvWDF commented 1 year ago

Hi Arduino uno, grbl an ugs. When I try cutting a circle it starts cutting clockwise until 180' and then comes straight down to the starting point. (Half e circle)

Already tried different cam programs to create gcode. 3 different arduino's. Open builds in stead of ugs. Switching x an y axle. But result is always the same.

Cnc does make a perfect square with correct measurements.

Who can help? Kind regards Ben

That's not a Grbl issue. What kind of machine?

MARIOBASZ commented 1 year ago

can you upload the example? it could be a code error.

Its a cnc plasma cutter. arduino+ grbl based.

same issue when plasma is connected or not... cables are shielded.

SailWithChips commented 1 year ago

Could you add your grbl settings?.

have you checked to start your program (gcode) on other place?, to check if its a hardware or softlimit for instance.

Hi

Today I reinstalled all the software concerning the cnc and that seamed to have solved the problem. Still don't know what went wrong.

Thans for the help! Kind regards Ben
