I’m experimenting with some custom g-code to release the print from the FEP with a straight vertical 5mm lift with no tilting of the vat. It’s kind of working - except the only way I can disable the tilt is to unplug the PM motor from the mainboard. I then set PM speed high to save time.
Basically I post process the G-code and insert an extra line to raise Z at each Z-change
G0 Z5.500000; lift z
G0 X61.448 Y61.957 Z0.5; output original g-code
M91 for relative gcode doesn’t appear to be recognised so running this
doesn’t raise by 5mm above the current layer - it seems to just send z to 5. I can work around that by saving the current layer height and adding 5mm when processing the g-code.
Second - the tilt motion is triggered on every z move - so I actually get 2 peels - unplugging the PM and setting PM speed high fixes this.
OK so there are 3 gotchas - the
lines reset something internally and me trying to fool it into raising Z between layers stops working after a few layers. If I remove all of the ;LAYER lines from the g-code it works exactly how I want - expect I get no indication on the LCD of what layer it’s on.
I noticed that there’s an M1004 gcode in the new firmware that’s supposed to trigger a peel motion - I’m wondering if there’s any G-code to disable peel/tilt… I tried messing the the PM reset position but the minimum value still seems to tilt.
