While I agree that I can make a jig, I make quite a few items in different sizes and would have to make a jig each time which is not practical from my point-of-view. I may be sticking my neck out here, but there must be a way to accomplish this in the software.
So… after playing around for a while, here whatI have accomplished so far -
Jog the head to image centre on workpiece -> Set Zero -> move my image in the workspace (Center 0,0) ->Run the job. The head moves to what seems to be the correct location to start the job, the laser fires BUT the Z-axis does not move down to the start height.
The Gcode however shows that the Z-axis move is there -
G21 G90 ; Pass 0 ; First Move G0 X-38.00 Y-38.00 ; Pass Z Height 15mm (Offset: 0mm) G0 Z15.000 ; Generated by LaserWeb (lw.raster-to-gcode.js) ; Size : 0 x 0 mm ; PPI : x: 300 - y: 300 ; PPM : x: 0.0846666667 - y: 0.0846666667 ; Tool diam. : 0.2 mm ; Feed rate : 4000 mm/min ; Beam range : 0 to 1 ; Beam power : 0 to 100 % ; Options : trimLine, joinPixel, burnWhite G1 F4000 G1 X-38.00 Y-38.00 S0.0000
Getting there slowly!! Any help to get over this Z-Axis issue sorted would be appreciated!!
