Seems like it isn't loading the bed level data. Tried putting the M501 command into the start Gcode, just made it ram the printhead into the bed. Please help me!

AI Help

It sounds like you may be having trouble with the bed leveling process on your 3D printer. I recommend checking your printer's documentation for the correct method to load bed level data. It's important to ensure the printer is properly leveled before starting a print to avoid any collisions. If you continue to experience issues, consider reaching out to the manufacturer for specific troubleshooting steps tailored to your printer model.

oh boy

Ye

#

I know it's something with the data not loading

#

But it didn't like M501, at least in this form

echo wolf
#

here is the default start gcode from orcaslicer
M413 S0 ; disable Power Loss Recovery
G90 ; use absolute coordinates
M83 ; extruder relative mode
M104 S120 ; set temporary nozzle temp to prevent oozing during homing and auto bed leveling
M140 S[bed_temperature_initial_layer_single] ; set final bed temp
G4 S10 ; allow partial nozzle warmup
G28 ; home all axis
;G29 ; run abl mesh
M420 S1 ; load mesh
G1 Z50 F240
G1 X2 Y10 F3000
M104 S[nozzle_temperature_initial_layer] ; set final nozzle temp
M190 S[bed_temperature_initial_layer_single] ; wait for bed temp to stabilize
M109 S[nozzle_temperature_initial_layer] ; wait for nozzle temp to stabilize

and default end from orcaslicaer

(both for your printer model)

My printer didn't like one custom command

echo wolf
#

which?

ornate canyon
#

Who says it'll be fine with 20 of them?

echo wolf
#

send your current start code

ornate canyon
# echo wolf which?

M501 made it ram the printhead into the bed (thank goodness I managed to cut the power in time or else the steppers would be fried!)

This is with M501

echo wolf
#

are you running bed mesh manually

#

if its not run that might be why it crashed

ornate canyon
#

It has auto bed leveling if that's what you need

#

Also, here's a possible cause of this: the data isn't saved so the mesh is 0 everywhere which makes it send the nozzle to my Z offset wwhich is negative

#

Maybe I should try to do the auto leveling in the start Gcode and make sure the data is saved?

echo wolf
#

just try the gcode i sent for start and end and see what happens, its designed for your printer so it should work

ornate canyon
#

Hmmm

#

Sussi but worth a try
