Hello! I am having a strange problem when cutting circles. for example, If I want a 23 mm circle it cuts 24.24mm? I calibrated the X & Y and when I cut out a 150 mm square it is almost dead on. 150.14 mm I can’t find any additional documentation on this issue other than calibrating the X & Y. Any suggestions will be very appreciated. I am running an Openbuilds 1515 CNC(Black Box/GRBL) with a Opt Laser Diode Laser( High-Performance OpenBuilds LEAD CNC Laser Upgrade with PLH3D-6W-XF+ and LaserDock)
1) check mechanicals (for example grubscrews on shaft couplers tight? Machine Trammed Tramming: A generic guideline, etc) 2) Then calibrate (Wizards and tools > Calibration) 3) Double check CAM workflow - maybe different laser spot diameters (offset)?
