LR4 Pen holder and what to do next?

[jeyeager (Jason Yeager)]

You are correct that when you home Z, Z0 is now at the top. So, you just need to jog down so the pen is touching or nearly touching, and then run your gcode. Since you’re not probing, you want to make sure you’re not using the starting gcode that probes.

Just posted this in another thread and it applies here as well:

@jeyeager

If you’re not using a probe, use this starting gcode instead:

G21
G90
G94
G92 X0 Y0 Z0
G1 Z10 F900
G00 X0.0000 Y0.0000 Z0.0000 F2400
G00 Z5.0000 F900

Notably that G92 X0 Y0 Z0 is going to set zero at the current XYZ position.
