Hey yall,
ive searched around and havent seen a solution to the problem i have been having.
My build plate was installed correctly, and my settings look correct, but all my prints are off-center by about 20mm left and 20mm front.
I checked the assembly, all aligned and proper
included are my configs and images. Anyone know how to correct this?
Firmware 1.11.4_20210201
Cura 4.8 -
Please post some more pictures. From the front and from the side so we can see more of your machine.
Was it so from the beginning or is the problem new?
I can’t actually remember if it was working right before the latest firmware update. I was printing on glass but had to put it all back stock. Now I’m trying to diagnose this problem before I go back.
whats that blue thing on your 3dp module?
can you jog 100 percent of the axis in question? maybe a switch is being triggered prematurely? and therefore the machine isnt where it thinks it is?
here is my cura setting. the values are for printhead are different than yours. were you trying to adjust something to compensate for the mod you made?
@gspeed its weird can not see that there is someting wrong with the assembly.
@MooseJuice The blue thing is Tones? probeholder I think.
Where in Cura can you choose the type of Snapmaker?
you cant in cura, i didnt look closely and assumed it was luban. i erased that
Hey do you have anything on the extruder tab
i wonder if you have any offset listed.
i also wonder if you were to apply one if it owuld help
Have you tried so reset the hole machine?
And another question: Where dit the printhead start? At X-10 Y-10 like you start gcode shows or is it at this point alreaday at X-20 and Y-20?
ok ill try to answer all the questions.
It makes me wonder if machine is trying to use the prox sensor location as the nozzle location.
There may be some hard coded offset in the firmware someplace that got changed when you were playing with something.
i dont know what it would be. @brent might have an idea about that
i droped down the firmware to 1.10 just now, reran calibration and im running a first layer test now. if there were any funky firmware settings they should be cleared. ill update once the test is done
alot of the gcode doesnt change from a firmware update, such as esteps
but i recon theres a factory reset on this thing someplace.
by gone i just finished a print and will look to confirm
if there is, im not seeing it
surely theres a way to define the offset from nozzle to sensor…
looks like M218 is the gcode for it, but im not sure that the values should be.
yeah so the downgrade didnt have any change on the alignment
M851 is the probe offset, hang on theres some info
got USB? do m851 and share the output.
if you do it with no values it should just have a readout
hmm why didnt it share the values of x and y
oh here
try M503 for a minute it should give some different info
if it gives like billions of line try to find lines related to 851 as well as 218
i really want to say just M851 X13 Y19.15 Z1 will fix the problem but id like to confirm waht is there first 
only because i havent really done this before.
we may have to wait for brent or someone else to chime in to either confirm or change directions on this
dont have my laptop home or id try to figure out how to force the value to be read for you.
im good with waiting, i actually wont be able to work on this till sunday.
but ill checkin and see what you guys think
that didnt give the information either. Lets sit tight. you can always goof about while waiting on it, just a lil off center 
Hi,
Brand new 250. It has the same offset issue.
