Work of art!

yep, full random mechanical work art!

maybe end stop problem

You can check if any wire stretching and causing the end stop switch triggered.

Looks like the motherboard is getting incorrect signals from the Z-Stop microswitch. Most likely cause is bad wiring somewhere betweena switch and the motherboard.

Use Pronterface or some other software that lets you test all the microswitches individ …… 查看更多

before you do anything please tighten the belts !

about the upgrade please Reupload it - it seems that somthing went wrong

Thx Clarence and Idan for your answer; 1) "Did you auto level first?" yep but has i say the screw dosen't work anymore... i'll try all configuration nothing works...the printer can't execute a correct G29...so... 2) "before you do anything pl ease tighten the belts !" curiously they are strained ... do you think I need to stretch them more? 3) "about the upgrade please Reupload it - it seems that somthing went wrong" Yes i think similar, but I already try its give nothing more the result doesen't change...

Thx Again for your help and your comments tomorow i try to reload the 2.0.3..

first screw setting

Second screw setting

Third screw setting

All settings totaly fail... the better result was obtained when the screw was squeezed at the most....

It's not all that difficult as it might seem, you can start by screwing it to the maximum and release a little at a time until it's perfect- I also adjust it in my atom every month or so

I will check for you later today about the software update- there are quite a few files to choose from- maybe you uploaded the wrong one

ok i finally resolved the screw problem G29 is good finally..but why this problem apear when i uplaod the 2.0.3 because my screw dosen't move meanwhile...? The 2.0.3 Firmware increese the scew setting sensivity ?

nope, it's not firmware related.
much related to the screw it's loosen

In any case Thx again for your council I shall wait for your return on files before making anything

could be the end stop defective?
