Delta FSR G32 Calibration Not Converging
-
-
Sorry to chime in again but I realized pic 2 and 3 are reversed from my description. The max deviation at a given point across the g30 s-1’s in pic 3 is .023 but most are much smaller. @dc42 I think I read anothe rpost of yours saying that with .9 steppers that I should be at .01 repeatability. Are the few that are over that a potential cause for the Before and After not converging with g32’s?
-
Tried more mechanics, new wheels and bearings, belts, tightened everything. This .02 tolerance on z probe with up to 3 tries at each point. No g28 between g32’s. Anyone have any ideas?
-
How tight is the bed in the bed clamps? On my Ultibots K250 when I had FSR's there was a very narrow range of tightness that they worked good but didn't allow layer shift.
-
Also changed the jumpers on the board for full sensitivity
-
I have printed different brackets than stock because of new magnetic bed. There is plenty of gap there. I never experience any layer shift. I’ve tried with sensitivity on the fsr’s all the way down to 25 and up to 500.
The After value always stabilizes but the Before cycles. It must have to do with the algorithm . -
I went to look for the jumper settings I mentioned that affect sensitive and it appears the newer JohnSL boards don't have them.
-
I think sensitivity is all in doftware now. I just replaced the fsr’s to see if that was it but still the same. I’m at wit’s end unless someone sees a pattern in these numbers that gives me a clue what to look for.

Are you sure the towers aren't out of alignment slightly?
-
Checked with machinist’s square.

If you calibrate a few times, then replace S6 by S-1 on the last G30 command in bed.g, then run the G32 several times again (it wont adjust the calibration, it will just print the errors), does it report consistent height errors?
