Title: Mach3 not machining to scale
Post by: Caucau on August 09, 2019, 04:18:05 AM

Mach3 not following Gcode drawing to scale. Gcode made in Aspire 8.5.
Cutter should have travelled 500mm but only moved 20mm.
Manually jogging the correct distances as displayed on mach3 but when Gcode is loaded it machines 1/20th the scale drawing. Scale is set to 1. Can anyone advise what I'm doing wrong?

Hi,
is it 1/20th scale....or could it be 1/25th scale....or 1/25.4th scale to be precise. If so the machine is interpreting the Gocde
as millimeter scale but the Gcode is written in inch scale, ie the object turns out 1/25.4 th of full size.

Gcode written in mm

could it be related to the Configure Initial State settings or select native units - "set default units for setup" ( machine set to inches in "units for motor setup dialog")?
