Tramming cylinder printer test

Tramming is usually done on milling machines etc. but on printers it is a bit extreme.

Everything we print is a leaning tower of Pisa and this test lets you measure how much. Honestly this is only important if you print threads or gears or parts that you bolt together.

The idea behind tramming is to make the three motion axis perpendicular to each other. Inexpensive printers do this with software which can create print artifacts. With this you can verify how well the software tramming functions or go the extra mile and correct the printer mechanical inaccuracies.

This test is for a well functioning printer. Your first printer test should be X-Y calibration which is all about printing round cylinders or right angle squares, then an extrusion calibration test.

Configure the slicer to NOT support threads and 30 degree overhanging surfaces or just turn off supports!

Print the cylinder on a raft. Mark on the cylinder the orientation
