Simplify3D Endcode for Bambu Lab X1C (Bed-Z)

I am using Simplify3D (version 5) with my new Bambu Lab X1C.

Now my question: Does anyone have the right setting in Simplify3D for the ENDCODE so that the bed does not move all the way down at the end?

Currently it always moves all the way down with the Bambu Lab Simplify3D default profile (even with small print objects) and the next time I start it I first have to manually move it up a bit, otherwise the X1C makes noises because the bed is at the bottom of the stop. (The bed is too low at this moment) The bed should simply not move down completely after printing, but as with the Bambu Studio end code. (the bed only moves down a little and NOT all the way down).

Does anyone also have the Bambu Lab X1C and is familiar with the S3D endcode?

Here is my current Simplify3D original end code for the X1C:

M400 ; finish moves
G92 E0
G1 E-0.8 F1800 ; retract
G1 X65 Y245 F12000 ; move to safe position
G1 Y265 F3000
G1 X65 Y245 F12000
G1 Y265 F3000
M400 ; finish moves
M981 S0 P20000 ; disable spaghetti detection
M140 S0 ; turn off heated build platform
M104 S0 ; turn off extruder
M106 S0 P1 ; turn off part cooling fan
M106 S0 P2 ; turn off auxiliary fan
M106 S0 P3 ; turn off exhaust fan
M17 S ; store motor current
M17 Z0.4 ; lower Z motor current
G1 Z256 F1200 ; move to top of machine
M400 ; finish moves
M17 R ; restore motor current
G1 X128 Y250 F3600
M400 P100 ; finish moves and beep
M73.2 R1.0 ; reset time remaining
M220 S100 ; reset feedrate
M221 S100 ; reset flowrate
M201.2 K1.0 ; reset acceleration magnitude
M17 X0.8 Y0.8 Z0.5 ; reduce motor current
M1002 set_gcode_claim_speed_level : 0

Many thanks, Moriis

Re: Simplify3D Endcode for Bambu Lab X1C (Bed-Z)

The line that does the Z move at the end is this one:
G1 Z256 F1200 ; move to top of machine

You can comment that out if you want to stop it from moving down. Or replace it with something like this if you want a smaller Z movement:
G91 ; relative movement mode
G1 Z10 F1200 ; lower Z by 10mm
G90 ; switch back to absolute movement mode

Last I checked, this same problem happened with the Bambu software as well, so perhaps the machine doesn't actually have a full 256mm Z height.

This is exactly what I was looking for. It works very well. Thanks a lot! 8-)
