cd3dmini K40 or lw4 or corel i have a scaling problem on imported svg from corel they are about 10% to short x and y is this what i change in the config.txt

Is there a gcode file i could use to check the setup scaling

# Arm solution configuration : Cartesian robot. Translates mm positions into stepper positions

alpha_steps_per_mm 157.575 # Steps per mm for alpha stepper

beta_steps_per_mm 157.575 # Steps per mm for beta stepper

gamma_steps_per_mm 1600 # Steps per mm for gamma stepper

I had same issue. Change SVG import pixels per inch to 90 in LW4 file settings. Fixed it for me. I don’t think Corel has a setting for this during export (at least that I’ve found).
