MC1.5 Strange Object Location

I just installed MatterControl 1.5, loaded a small test object and immediately ran into some strange behaviour. The object was correctly placed at 0,0 on a circular bed but after slicing it was moved off the edge of the bed. As well, in 2D Layer View the sliced object was placed far from the center and on a rectangular bed.

This leads me to believe that MatterControl placed the object at 0,0 on a circular coordinate system but then after slicing placed it at 0,0 on an incorrect rectangular coordinate system.

Here are some screen shots...

I won't try to print this because it may run the head into one of the towers.

It surprises me they haven't fixed that with the new release. Slic3r changed the way they define the bed shape and the integration with MC didn't incorporate the change. You can either choose one of the other slicers integrated with MC or download Slic3r as a standalone program and import the gcode it generates into MC.

I am running 1.5.6318 and have never yet seen that happen.(using MatterControl)

Slic3r still does not work.

Ah yes...Slic3r versus MatterSlicer. I neglected to check that.

Thanks

Wish I would have seen this sooner. Ran into this a long time ago and just had to remember how to do it. It is an issue with Slic3r and the 1.5 matter control if I remember correctly. Anyway short story it thinks you are starting at X100 Y100. Just export the Gcode and modify your first G92 E0 line to G92 X100 Y100 E0. It will start the print in the center.

Example

; generated by Slic3r 1.2.9 on 2016-08-11 at 21:41:58

; external perimeters extrusion width = 0.55mm
; perimeters extrusion width = 0.55mm
; infill extrusion width = 0.55mm
; solid infill extrusion width = 0.55mm
; top infill extrusion width = 0.55mm

M107
M104 S165
M190 S60
M109 S165
G28
G21 ; set units to millimeters
G90 ; use absolute coordinates
M82 ; use absolute distances for extrusion
G92 X100 Y100 E0
