Hi Snapmakers,
I just get my new A350T and after careful assembling and first start made proceed with firmware update … everything was fine. (3D print head and bed were assembled. Then i should do autoleveling…and that’s wired part. Snapmaker drive in Z+MAX(max up), X MIN (max left) and bed to ref.points (max and min), then drive 8 from 9 points (auto leveling 3x3 fields) BUT Z always says in MAX?! does not drive to 0 (auto leveling)… At 9th point stay and wait on manual leveling (Z is still on MAX so that i need at least 5 min to drive to 0 in 0,5 mm steps). Something is wrong…but what?
I check all cabels, contoller, converter (X and Z), plugs … everything is fine… Also manually i can drive all axis in all directions from min to max…
If I press on home button, then drive as described abowe… interesting is that Z and Y are on MAX (position Numbers) and X is on -19…
Manual leveling works (autoleveling off) and in this case snapmaker drive 9 points with Z on + 5mm… that’s i think normal (because it’s not much to drive to 0)…
Anybody some idea? Do I make something wrong?Any suggestions to check?
Thanks in Advance
Harry
When you say ‘converer (X and Z)’ do you mean combiner, where two cables go in and one comes out? Should be Y and Z.
Might be useful if you make a short video and also photos of your build from various angles.

Hi albutch,
Thanks for responding! Sry…my fault! Yes I wrote about 2 converters (2 to 1) for Y and Z axis (and not X and Z how i wrote it - typing error)…
In the meantime is the movie and the log files “on the way” to SM support…
