Geeetech

Hi i recently bought a A30 printer.

it worked really well at the first print. i used the file that was already on the sd-card of the A30.

the next day i moved the printer into another room and wanted to print some custom prints but since then there is a huge axis offset.
all models are now way out of the middle of the headbed. even the already printed and standard A30 model that worked before is now not printing in the middle.
if i use the bedlevel feature and command to move to the positions 1-5 i have a huge offset there in the X and Y axis.
like X7 and Y10 mm.

also he wont move all the way to position 1 and 2 (top right and left) when leveling

Z Axis is fine

ive updated the firmware but it didnt change anything.

any tips how i can fix that problem?

thanks for the reply sadly that only shows me how to level the bed, i did that already

the nozzle will not move all the way to the top right and top left if i press position 1 and 2 on the printer display

Like me, it's most likely your endstops. I printed adjustable ones from thingiverse and got it centered, using the full build size, but am now battling nozzle crashes. Can't seem to win.

Hi，maybe you can adjust the height of the distance between the nozzle and the hotbed.

It will print off center as the actual print bed is 330x330 Just thought I would mention it, As I had the same problem with My Geeetech A10 the print bed size is 235x235. on the A10 I just changed it in Cura, But on The A30 I Think its built into the firmware when you check information it has 320x320x420 But really its 330x330.

... even my A30 did not print in the middle (offset to the front and right), so I could not use the entire print bed.
Solution: print a symmetrical test object, centered with e.g. Cura, measure distances to the edges, and enter half the page difference for the slicer (such as Cura) under Settings - Manage Printers - Device Settings under X- Offset and Y- Offset.
Then everything is printed centered again.

Yeah that's what I was doing. But it still wouldn't use the back one inch of bed, and right half inch or so. It stopped there and made straight lines. By installing the adjustable end stops, I got it all centered, and using the entire bed.

Maybe this is solution for you:

Yeah it pretty much was. I ended up printing the new end stops and adjusting. It worked like a charm. Didn't take long to zero them in.
