That looks like that might be the problem. Sending the tip to 0 using G1 F60 Z0 Had it a little too high. but this is still different than what it Cura did, which was much higher. also, when I set the Z offset for the BLTouch and used that command, I could've sworn it wasn't too high. I'll investigate the settings of the Duet and get back to you. Update: 2 minutes later: looks like I put the offset as negative instead of positive. I don't know why it homed correctly this and hit Z0 properly yesterday.

Hi All! I have an Ender 3 Pro, modified with a Duet 2 Maestro running RepRap 3.0 Beta 12. I've also modified it to include a BLTouch. So printing it using the default (Marlin, presumably) configuration in Cura, resulted in it printing really, really slow. it also set the Z axis maybe 10 or so MM too high. that was using this start Gcode: M201 X500.00 Y500.00 Z100.00 E5000.00 ;Setup machine max acceleration M203 X500.00 Y500.00 Z10.00 E50.00 ;Setup machine max feedrate M204 P500.00 R1000.00 T500.00 ;Setup Print/Retract/Travel acceleration M205 X8.00 Y8.00 Z0.40 E5.00 ;Setup Jerk M220 S100 ;Reset Feedrate M221 S100 ;Reset Flowrate G28 ;Home G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up G1 X10.1 Y20 Z0.28 F5000.0 ;Move to start position G1 X10.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X10.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X10.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up Although, I modified it to RepRap Flavor, and kinda mixed the two start Gcodes, to create this: G28 ;Home ;G1 Z15.0 F6000 ;Move the platform down 15mm ;Prime the extruder ;G92 E0 ;G1 F200 E3 ;G92 E0 G1 Z2.0 F3000 ;Move Z Axis up G1 X10.1 Y20 Z0.28 F5000.0 ;Move to start position G1 X10.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X10.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X10.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up And the result is that it isn't unbearably slow, but the problem of being way to high on the Z axis still persists. I did a mesh Grid with 121 points or so before all of this using the duet. Shown is the Height map if it helps.
