Thanks! You got me interested in Linux CNC, I think it is like an automatic positioning system that can be infinitely adapting to environment, will read more into it, thanks!

Man, you've just cleared up some things that I was always confused about. The thing that you explained here: (kzfaq.info/get/bejne/hc2Hdt1m36q0cqM.html), haunted me ever since I've started linuxcnc, and din't understood that properly. Wish I had these resources before I've made my controller, it would have saved me a lot of time. Thanks for the great work!

You give nice explanations. I have an unrelated question: can you offer any insight on stepper motor tuning, NOT using the config wizard? I built a four axis router table years ago, running one of the first versions of Debian that had LinuxCNC. I don’t want to use the wizard because I have a lot going on in the ini and Hal files. I used hidcomp to connect my home made pendant, so I am reluctant to update.

What are you trying to tune about them?

@@TheFeralEngineer They run fine, but I feel like I could get more speed, and/or smoother running.

@@johnalex3023 that would just be velocity and acceleration settings in your ini file, then. No need to use the wizards 🐱

@@TheFeralEngineer Yes, but is it as simple as just tweaking the numbers until I’m happy, or is there a relationship/formula?

@@johnalex3023 nah, just adjust until you're happy. No real formula. If you lose steps on take off, you went too hard, too quickly, so reduce acceleration. If you lose steps in the middle of a long rapid move, reduce rapid velocity. The whole crank it until it snaps and back it off 10% philosophy kinda holds true in some ways.
