Skew Compensation Procedure

[Adamfilip]

I was trying to find more information on the exact steps required to do the skew compensation feature in reprap firmware. I found a folder of stl files. but no real info on how to proceed.

I assume you've seen this? https://duet3d.dozuki.com/Wiki/Gcode#Section_M556_Axis_skew_compensation

I haven'tt been able to find anything else.

Yes ive seen that page/link and the Github link. but its really lacking in clear direction. step by step instructions

@Adamfilip Try here: http://reprapltd.com/reprappro/documentation/ormerod-2/axis-compensation/index.html#Orthogonal_Axis_Compensation

Caveat: this is from the old RepRapPro instructions, and the firmware version running then was 1.05! YMMV.

But the only reason to use M556 is if you've built your machine skewed. Like all compensation, it's better to get it physically and mechanically square, and run with minimal compensation.
