Plotter This Plotter uses Core XY. You can draw art work, schematics or scratch PC Boards it is fast and fun. Servo goes to End Stop +Z
Penned Out Dip Trace file before Scratching PC Board.
Board is on light table.
I use DipTrace, Flat Cam and Universal G Code Sender. You must edit the G code for the servo.
Z up is M5 and Z down M3 S030
Plotter will draw 300mm by 170mm, no limit switches, I use the Core XY GBRL.9 to set the limit.
