Backlash compensator post-processor
I appreciate this is an old topic, but that backlash on direction change was my issue no matter how much I fine tuned my 1000mmx1000mm WorkBee OX running on Duet3D RepRap, and I couldn't find an acceptable software solution. I also had a couple of issues with post-processor that were available for RepRap CNC, so I made (and will continue to improve) this Fusion 360 Ultimate Post-Processor for RepRap!
Get it here from GitHub: https://github.com/BruceRoyce/UltimateRepRapPost/blob/main/UltimateRRPost.cps
When posting check "Apply Backlash Compensation" on the side panel, under Linear Backlash Compensation options and input 2 measured backlash on each axis (the offset for 1mm motion on direction change and for 10mm motion on each axis. Input 0 if none, see image below) and let it take care of backlashes by adjusting movements.
This in no way is a replacement for adjusting your config.g parameters and/or tuning the hardware to the best of your capability. It's only a final resort to overcome backlash.
It also takes care of manual tool change, corner or Z-probing, beeps when operator attention is required, fixes WCS issues and more.
