Thread: Start G-Code

    Start G-Code

    Hi

    I have a Ender 3 Pro and I use the Prusa Slic3r.

    I've recently upgraded to the Micro Swiss Direct Drive kit and it includes some G-Code that I need to run at the start to adjust the x, y origins.

    However, this causes the head to run along the X axis right where my clips are for holding my glass, plus I like the Prusa start up G-Code as it runs two lines up the left on the Y axis to get the filament going.

    Is there anyone who could help me incorporate the two start up codes, so i adjust the x, y but also run my usual Prusa start sequence?

    The Micro Swiss G-code is:
    G28 ; home all axes
    G92 X-5.0 Y-10.0 ; set home offsets
    G1 X0 Y0 Z0.2 F3000 ; get ready to prime
    G92 E0 ; reset extrusion distance
    G1 X160 E15 F600 ; prime nozzle
    G1 X180 F5000 ; quick wipe

    And my current Prusa start-up is:
    G90 ; use absolute coordinates
    M83 ; extruder relative mode
    M104 S[first_layer_temperature] ; set extruder temp
    M140 S[first_layer_bed_temperature] ; set bed temp
    M190 S[first_layer_bed_temperature] ; wait for bed temp
    M109 S[first_layer_temperature] ; wait for extruder temp
    G28 ; home all
    G1 Z2 F240
    G1 X2 Y10 F3000
    G1 Z0.28 F240
    G92 E0.0
    G1 Y190 E15.0 F1500.0 ; intro line
    G1 X2.3 F5000
    G1 Y10 E30 F1200.0 ; intro line
    G92 E0.0

    Thanks

    Adam

    I have the same DD. I did not change start gcode, but instead adjusted bltouch mount offset in the firmware. What solution fixed the issue for you?
