Zero X & Y question (Dual Hybrid) When I tell the printer home, isn't it supposed to go toward the 0,0 area? Mine finds the limits just fine and the moves toward the middle of the bed and stops there. It knows the X is not at 0, says it is a 38, I assume this is the defaults. I am reading section: http://wiki.e3d-online.com/wiki/Printer_Commissioning#.285.29_Zero_X_.26_Y but I don't see where I set the home position to 0,0 or do I need to? I want to proceed to (8) Dual Nozzle Alignment http://wiki.e3d-online.com/wiki/Printer_Commissioning#.288.29_Dual_Nozzle_Alignment I just want to be sure I am OK to proceed.
I made some changes and I am worse off. Now the printer thinks the 0.0 home is off the grid completely
Weird. I just re-powered it back on and it seems right again. OK. Moving on to get the difference between the two nozzles. Seems easy enough. I have them both set at the same height already. Go my numbers: X1 = 131.9 X2 = 94.3 Y1 = 8.4 Y2 = 7.1 Math... 131.9-94.3 = 37.6 8.4 - 7.1 = 1.3 So I will set as M218 T1 X7.6 Y1.3
Homing is a multi step process, first the machine homes Y, then X, then Z but for Z it has to move the sensor back above the bed otherwise it could not detect the bed. So it leaves the previously found 0,0 position. But that is all done by the one command "Auto home" or a G28. When finished the machine is not at 0,0,0 but that does not matter. If you wanna check your limits and that 0,0 is really 0,0 move the axes with the LCD to 0,0 and see where you nozzle is...
