X, Y, Co-ordinate problems
I'm having some problems with work and extruder positions on the print bed - also a possible related Z probe position issue that may be related but I'll try and get the initial positions sorted first!
Usable print bed area is 850mm (X) by 600mm (Y).
Two extruder setup, second extruder is 134mm behind the first on the X plane.
The extruder offset is set in the firmware and set to zero in sli3cr. Printing a part with either extruder results and the same printing position so the offset would seem to be working ok.
The first issue is that when extruder 2 is selected the gantry moves forward after homing 134mm to place extruder 2 in the same position as number 1 correctly applying the offset. However it is still possible to command a full 850mm X positive move resulting in a X axis end crash.
The second issue is positioning the work on the bed prior to slicing. Using the "center object" command results in the object printing correctly in the center of the bed using either extruder but according to the host seems to be at a completely random location in regards to the X,Y distance - see screen shot.
Centre of the bed should be, X = 425mm, Y = 300mm. However in the host the center shows as, X = 130mm, Y = 337mm.
I'd be grateful if anyone can show me where I've set this up wrong!
