I'm moving from Marlin to Smoothie (like a lot of people!) and I'm also starting with my first CoreXY (I have one grabber). Almost everything is working, but I have some questions/problemas.
First, I'm using 'that' board that I shouldn't say the name here. The 'why' is because for now, I, unfortunately, can't afford an original smoothie board, specially here in Brazil. But is on 'to-do' list buy an original when is possible.
1) Is there any way to setup position for Z homing? For example: after homing X and Y, I woule like to home Z with carriage on center of bed (assuming I'm using only "G28" code, withou X, Y or Z parameter).
2) My moviment area is bigger than my heated bed. For now, my heatedbed is 200x200mm, but my movement is about 300x350. To 'limit' this, I'm using "beta_min" with negative value to 'offset' my zero point. Is this the right way to do it? Or there is an 'offset' parameter to setup in configuration? I know that I can setup using GCode, but I would like to make it permanent.
3) I'm trying to use current module, but my motors are getting VERY, VERY hot, even stopped! All my motors are rated 1.5A and I'm using 1.1A in configuration…..still, motors get veryyyyyyyy hot (after about 7 minutes) without working, just stoped! Is there any calibration that I should do?
If i setup for something like 0.7 (current setting), motor keeps just warm, which is OK and normal.
