I’m just starting out with 3D printing and is in search for Gcode for Start Stop.
preferably with Start and bed leveling included, and a fix that some youtuber raised the problem with head and bed heating simultaiously didnt work (you probably already fixed that).
Best regards Morgan
My Start-Endcode for Prusa Slicer with Marlin:
G90 ; Use absoulte coordinates
M83 ; Extruder relative mode

M117 prepare Printer
M104 S165 ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
G28 ; Home all axes
G29 A ; Unified bed-level
G29 L0 ; Load Mesh Slot 0
G29 J3 ; Probe 9 points to check mesh
M117 heating up

M104 S0 ; kill extruder temperature
M140 S0 ; kill bed temperature
M107 ; kill fan
M84 X Y E ; DISABLE ALL STEPPERS BUT Z
Hey! I’ve recently found this start and end code pretty useful. Is there any way to change the temps that it sets when probing the 9 points during auto bed levelling? I want to increase them to my actually printing temps. Cheers!
Hi, I would not recommend the printing temperature at the probing. Because the filament can run out of the nozzle during probing and the print bed is then littered with small filament drops.
If you still want to do this, replace the following:
M104 S165 ; set etruder temp
to:
M104 S[first_layer_temperature] ; set extruder temp
Are the M140 and M104 commands necessary if they are after the 190 and 109? I’m just now learning G-Code and wasn’t sure.
I’m planning on adding a mesh check in my start code for a dual reason, to make sure the mesh is current and also to allow some heat soak on the bed. I have had issues with adhesion on a fresh bed.
The M104 and M140 are not necessary before the M109 and M190, but are recommended by Marlin and RepRap. The bed mesh should always be made in the heated state in order to measure the bed in its real state. I swapped my bed for a flat, finely milled cast aluminum bed. Everything absolutely plan. But if the Z-offset doesn’t match, this doesn’t help anymore either.
OP likely meant probing the bed at 90, instead of 60…
This is a script that always automatically takes the temperature for the bed from your filament settings. When the filament is deposited correctly. Then the ASA checks with 100 degrees or depending on what you have integrated for your filament.
you can also just hit prepare on the printer heads up display and then temperature to warm the nozzle and the bed.
