Leadscrew G32 distance.



  • I think I can only get so close with my distances to the lead screws for the g32 level.(dual independent) I think I saw a thread were dc42 might have been talking about it but he used words I didn't know. There should be a way to run the g32 then it adjust the lead screw distances to get closer and repeats till its perfect. I was thinking i could do it with conditional gcode but now i think it has to be in the firmware.



  • Could you describe more about your configuration and what you are trying to do?

    You should probe as close to the lead screws as possible, but you obviously can't probe directly on them. That's ok. It's going to be an iterative process anyway. You don't need conditional gcode to run it more than once, just copy the gcodes a couple times over in bed.g. Once it's close it usually gets dialed in after 2 or 3 passes.



  • I have it working really good. I just know that my distances to the lead screws are just a close reference and I think that's where the small error comes in when doing a G32. I think there is a formula that will figure out what the true distance is, It might only have to run g32 once. Maybe save the new distances in the pid folder(M501) I love the way it is now. It might be easier to set one lead screw as a pivot point (dual independent) instead of X0 or Y0 if a formula would work.
