Large Format Prusa  

New Member

So i am building a Large format prusa i have the new bed dimensions saved in and manually or through G commands it moves fine. but now i am trying to get the Z calibration to work but when it goes to raise Z it wont move and makes the load vibrating noise. If I use my hand to assist it it will then move up.  manually Z will move up fine just not when I do the calibration. i have tried adjusting speed parameters which didn't help.  feels like it decreases the Current for Z calibration.  The only setting that would have it move up was taking stallguard down from 4 to 2 or 3 then it would move up but only 5 to 10mm then stop thinking it hit the limit.  been trying to find something current related or other settings to get the Z calibration to work since its such an important feature.  Thanks
