Only other thing I noticed, when I press release tension, nothing happens, it makes a slight noise but tension is still there. If I press it again, then at releases it, but then you have to go through retract/extend procedure. ---

@themanro This is just a thought because I dont know how calibration is retained in the memory. Could it have over compensated with the arms being in the wrong position and it needs to be loaded from scratch? ---

This calibration was done with clean yaml file. I think it did help to not get stuck in low fitness loop. ---

Hmmm…Can you try running the calibration process with a lower calibration force? ![image](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/2/4/2480d39a8e68c536b8b5ed44ebc7659513b24dfa.png) That should reduce the tension in the belts ---

If the Z offsets are wrong for the arms, the coordinates are going to be wrong (and the fitness will suffer as well) David Lang ---

UPD: We are cutting! I removed the wing nuts from the bolts where belt anchors go, so they can pivot. That alone improved a lot of things. Calibration ran without hiccups. Sled still lift ever so slightly in places, but one I get vacuum hooked up it should be enough weight to keep it down. There is some stutter here and there, so I’m going to try adding some wax to the bottom of the sled. Accuracy is pretty good, however I had a 5mm deviation on one of the corners of the bottom shelf piece. Not sure what caused that. I think that was near the corner of plywood sheet. So maybe I need to calibrate using even larger perimeter (I did 2000x1000). There was a hiccup with the travel passes, where bit was suppose to be above the surface, but didn’t. That might be those settings in fusion that I didn’t get right. Overall, not too terrible for a first cut. ![IMG_5320.HEIC](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/7/2/72fe10b6d230fffb6cef42f8ad8e0c8557e00047.jpeg) ![IMG_5325.HEIC](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/e/f/ef7a78714f5b9d59ffc85daec5e2c62f453667aa.jpeg) ![IMG_5318.HEIC](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/3/e/3e3483b2cfde8f17697b65b80ff98e01081972f0.jpeg) ![IMG_5324.HEIC](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/8/d/8d7d95b5ddc4e14c064975dca43c158a43fb8675.jpeg) ![Screenshot 2025-06-11 at 16.06.41](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/8/6/8622ade002f1325dd12f6ee4872d0deb7bd652d5.png) ![IMG_5331.HEIC](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/3/9/395d7ddaa7e146a3e7b7f07e3c79e5a2575d21ec.jpeg) ![IMG_5332.HEIC](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/3X/8/f/8ff25fadba47bf6792735d9dd8fff0f876f0e417.jpeg) ---

I am after this too. What was your fitness score that you cut the box jointed box with? Also I am wondering now if changing the calibration force will make a difference in fitness that will affect accuracy. ---

Testing that out today. I will check on the fitness score. I think my inaccuracy could be due to the bottom belts fighting up in the bottom corners a bit. ---
