I will have Cluster print 2 PP-GP0330's on Gladiolas and 2 on Hibiscus tomorrow. Then we will line up the holes and see if it is a printer type issue. I will post the results here on Monday and then we can proceed from there.
Yes, while evaluating printed part non-conforming materials I came across a bag of these parts that had been tagged for this issue. After fit testing them, I found that most of them were usable, but with considerable difficulty. Part of what increased that difficulty was dimensional inaccuracy, which has been found on Mini 2 prints of this part. Other issues with this part included warp/lifting at the corners, difficulty removing the built in support material, and inserts installed in a hole where they are not needed.
I sought to alleviate all of these issues, made and tested model changes, and created a change request to implement these changes into production: T6321
Prior to Change Request creation, slices of the new model were run on Mini and Mini 2 in the cluster and fit tested to ensure identical functionality. The Mini 2 slice utilizes M92 to set X/Y steps/mm to 100.6, which had been found to be the correct adjustment to achieve parts with correct dimensions.
