Weird behavior calibrating Delta
-
Hi guys,
I have been trying to tune and tweak my delta for the past week or so, and have seemed to fix most of my dumb mistakes. The only trouble I’m having right now is that when I run G32 my smart effector will not trigger at one point on the bed. It isn’t consistent, but it does happen frequently. I can run a few auto calibrations before it decides to not trigger at this one point.
Here’s a video of what I’m talking about https://imgur.com/gallery/alxkiDI

@dc42 Im hoping you might be able to help me
-
maybe increase the sensitivity by just a bit.
-
I had tried that. It didn’t seem to work and just made other points not trigger when running. I believe what I might have to do is go through the bed.g points and enter their individual trigger heights

@BigMoff96 said in Weird behavior calibrating Delta:
M558 C"zprobe.in+zprobe.mod" P8 R0.4 F1000 B1 H10 T6000 ; set Z probe type to effector and the dive height + speeds
then try increasing the F value
and maybe the z acceleration.
M201 X1000.00 Y1000.00 Z1000.00 E1000.00 ; set accelerations (mm/s^2) -
You think 1200 or 1500 mm/s for z acceleration?
-
you have to test it. the idea is to increase the force with which the nozzle hits the bed.
