The z tops are tending to warp on the ends, I think we could modify the geometry somehow to mitigate this.

M4: More materials in quickprint
From the small sample that I had (3 prints) I saw an improvement on lifting. The areas that lifted were much less severe with the helpers in place. I think a combination of slice adjustments and those features will resolve my issues
Always worth a try i suppose.
Eliminating the fastener is preferred; I don't think it will cause any cosmetic issues that would be more concerning than a part that doesn't mate nicely with the top plate because of persistent warp. It really cleans up the look of the Z-tops.
@Steven I am sure a higher passing rate would happen off of TAZ machines; however, part of the reason for the part change was to open the opportunity to print it on mini which is the majority of cluster. The primary reason I see lift is usually due to the corners getting neglected when sanding in cluster, which makes sense, the majority of parts have their critical geometries in the center of the bed while printing.
@tutley I built the profile off of the standard, yes it does work well initially on a machine that is watched. Sending to 10 machines blind in cluster gives varied results. It is less than 30% of prints where the lift is bad enough to fail the part, I am sure with enough time we can work out some settings to find the 'Goldilocks' solution.
There have been some adjustments made to some prototype parts which remove the need for M2 inserts and screws as well as the M4 fasteners. I have only printed a handful so far and the results are better, less complex geometry around those areas helps keep the temperature more consistent while printing. Due to the vertical print orientation of the M4 holes on those 'prongs' we see the tool-head retract and travel over those areas more than if it was a solid wall, with how hot the enclosures get combined with the heat of the tool-head and bed it makes sense that less geometry will give more consistent results due to the more uniform cooling that is happening.
Ok we have installed these on 4 machines now and they are working as expected.
