X shifted 4mm away from 0 when printing max size
-
X axis not centered.
Just printed a part that is 199mm wide and the print surface should be able to do 200mm. The part is centered in S3D and in the past with the original Rambo board would print within the confides of the bed. This print is shifted to the right by 4 or 5 mm (towards 200)
What config param should I be looking at to correct this?
There is no adjustment on the end stop, so that has not changed.. Parts are the correct size so can not see it being a steps thing.. What am I missing. Maybe this is the issue, the nozzle goes off the bed to purge so I set the max X to 230. would not think that would impact an object centered by the slicer which states max X as 200.. -
Can you share your config.g and homing files?

Where exactly does it go off the edge?

@Phaedrux Hey Sorry for not being more clear.. When the job starts the start script moves the nozzle to X205 and purges, then moves to start printing. That is normal. When the part is 199mm and centered the side of the part that should be at zero (left side with end stop) is about 4mm to the right.. when X is homed it is also in about this same place. I was able to get the part to print by moving the magnetic plate to the right but just trying to understand why this is happening. The end stop switch is fixed so not sure what is going on. This may be the first full width print since switching to duet.
I moved the model towards zero in the slicer and when printed the skirt is printed where the outer perimeter should be and that is 4mm in from the edge.. Not sure how else to describe it..
I guess I could try bending the limit switch arm in to move things over.. -
@airscapes Here is an image that may help explain

@Phaedrux Sure not sure the best way, I guess code tags?

So when the X endstop is triggered, is the nozzle tip right on the edge of the printable area?
-
@Phaedrux No it is not, so I went ahead and bent the arm of the switch moving the nozzle to the left a couple of mm which now produces a center build area on the plate. Sorry for wasting your time, I did not think that this would be the way to fix the problem but I guess since it seems to work, it is!
-
You could also adjust the M208 minima to be slightly negative, so that it knows the nozzle tip is slightly off the edge of the bed when it triggers. Either way, same result.

@Phaedrux I did try that last night and I think when I homed it, it was at the edge but then printing ignored it.. I did post in the nearly dead MG forum about adjust the x limit switch.. no response, but things are bleak for MG.. still in business but not by much..
