Skew Test
thingiverse
This is a quick test to see if you have a problem with skew caused by a skipped tooth. Symptoms are that printer makes more whirring noise and that parts have different width to height dimension (like a skewed square). Must be printed with the widest part of the model perpendicular to the axis you wish to test (as in picture - overhead view) Test by putting each part inside the other as in the pictures. This is from a Flashforge Creator Pro with a pretty standard 2mm tooth pitch. The error is quite significant. I fixed mine by slipping the end of the belt on one side out with nose pliers then wiggling it and slipping it back again - lucked out that it corrected itself.
