Hi there I’m wondering if anyone might know a workaround to let me level the bed of my printer without the touchscreen module as mine is missing and I don’t really have the funds to replace it right now.
I’ve tried tapping gcode into the console but g1029 just returns an OK and nothing happens.
I’m very new to this so instructions for an idiot would be appreciated.
You could try the solution in these threads and see if they works for you:
You have a snapmaker original, right?
Because the instructions were for 2.0 and might not work.
Original calibration is only 3x3 because of bed size.
Thank you very much for the quick reply mate, unfortunately as stated the machine just responds with OK and does nothing if you send command G1029
I did find in the Marlin documentation however (on which snapmaker is based) the gcode command G29, which seems to work much the same as autocalibration with the screen.
BUT
I now have a new problem, in trying to get the machine to respond to various gcode in the snapmaker doc I have updated the machine’s firmware and now it seems to believe the bed is much lower than it actually is. So when I send it home it is now going to these co-ordinates:
Which is far lower than it did previously and as such attempting to level makes the nozzle knock against the side of the bed . Anyone got any ideas?
Send it a M502 to reset the settings to original and save it with M500.
Have a look at this, point 7, virtual bed level:
Thanks I tried that method you link to there,it might have worked, it might not, honestly I can’t tell because no matter what I try, the Z Axis is just not playing nice for me.
Home is still set below the build plate but trying to print something results in it starting in mid air.
This has only been the case since I updated the firmware.
My first picture there is where X0 Y0 Z0 is putting the nozzle, and the second is it starting to print in midair, I’m losing hope with this honestly.
Did you reset to factory settings and the level your bed like described in the linked thread?
Share your M503 here before reseting with M502 and saving with M500.
Did you ever print something on your machine?

This means you didnt edit (and save?) your grid correctly.
Have to look at my old M503 records about the offset but it seems ok for me.
Offset on my old machine:
: echo:Home offset (mm):
Recv: echo: M206 X-4.50 Y-5.50 Z-5.40
Try to edit the grid again and view your M503 if it works, or report your grid here nsand i could help you further.
Okay so I’ve had a fiddle around again, adjusted my offset so that 0,0,0 was sitting appropriately on the bed and then set my grid again, here’s my M503 now

ok
and here is the result with it once again printing in mid-air
on top of that my 0,0,0 seems to have shifted from the test print so that it now floats too
