BTW I noticed this time that if I have the ui up on my computer and tablet, then I can go out to the garage with the tablet, and come back to a full console of stuff on the computer and it is QUITE a lot faster computing fitness šŸ™‚ ---

I think that there is something funky going on that both you and @Frank_Wiebenga are dealing with. It feels like the same issue to me. You are both getting normal behavior, nothing clearly wrong but then the calibration results are weirdly low. I am 500% stumped on what it is. ---

Since this last one was at least stable now that I have the arms on (maybe) right, Iā€™ll try a 4 x 6 or so and see what I get. Also I do have at least one if not two belts that have some chewed up areas, so Iā€™ll rebuild and try this again once I get the new belts. Right now, Iā€™d really like a feature whereby once Iā€™ve retracted / extended the machine keeps track of that enough that I can just update the calibration settings and start from there instead of having to retract/extend again. Retracting for me as you know is a pretty onerous process, although better now that I can custom extend my top belts more šŸ˜‰ but still two trips up and down the ladderā€¦ ---

OK, we may have a breakthrough. @ronlawrence3 and @Frank_Wiebenga would you guys both be willing to give > [@Interstitial Firmware Releases](https://forums.maslowcnc.com/t/interstitial-firmware-releases/20215/43): > > 0.66.8 A try? Basically just press Retract All ā†’ Extend All then 1,000mm of belt (measured by the white part showing, length is 0 when fully retracted) will extend and can you measure that belt with a tape measure? It will be slightly more than 1,000mm because of a little overshoot but it should be like 1009 or something like that. ---

Before you do the whole process, can you give 0.66.8 a try? I think that we might have some sort of an issue there which could solve the whole thing. ---

It isnā€™t on Maslow-Main because it canā€™t be used for actual calibration or cutting or anything, itā€™s just a test firmware which can only extend. If you want to grab the branch itā€™s called [Extend-1000mm](https://github.com/BarbourSmith/FluidNC/tree/Extend-1000mm). What weā€™re looking for is these values + the actual measured values with a tape measure. ![image](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/a/0/a02612991e1bef0351b2d0ebf4827ba1d98ceffe.png) ---

I have obviously not tried (nor can I easily) horizontally. I wonder if I were to be either landscape vertical or horizontal if Iā€™d get better results. I will have to wait for the weekend on trying any of that as I canā€™t manipulate this monster frame by myself and Iā€™d have to clear out the garage a bit to get it landscape. ---
