Delta Calibration Cross Scale and Step

This is a calibration test I created for checking scaling and rod length on my delta. I added a 50mm tall step test for verifying motor steps/mm. Each Step is 10mm and it's 10mm thick.

If the steps print accurately, ie the top step is 50mm tall, then move on to testing scaling issues below. For my D300VS it's 800 steps/mm. If the error grows from step to step then the steps/mm need to be adjusted. Note: Slicing software can have an affect on exact height along with extruder ratio. My p
