Issues with my Duet2 wifi delta printer auto calibration

sneakyferret

Hello there. I am having a big problem with my Delta printer. At one point I managed to get it to print a small calibration cube. Afterwards, I tried to print a large rectangular piece that was much wider. I noticed low spots and high spots and decided to try to better level my bed. After rebuilding my bed file, now after auto calibration my effector nozzle runs off the bed after the 3rd test point. This is what happens. If I let it continue it will collide with the belt.

Here is my config file. Let me know what other files I can give to assist with help. I am using a He3d printer frame with a Duet3d wifi 2 controller, a duet3d smart effector, and carbon fiber magball rod ends (unsure of the model but theyre a decent quality all from a friend who got out of printing).

@sneakyferret
You might have an old config-override file on SD card which messes up the printer?
Or you have to generate a new bed.g file with correct radius parameter?
radius = diameter/2

@sneakyferret said in Issues with my Duet2 wifi delta printer auto calibration:

; Tools
M563 P0 D0 H1 ; define tool 0

on another note, you should associate the part cooling fan to the tool. Add F0 to the end of M563 e.g. M563 P0 D0 H1 F0

@o_lampe Thanks for the reply. What about my radius is incorrect? I have a 310mm diameter print bed that i am using a radius of 138 to account for clips that secure my printing mirror to the heated bed so I didn't want my nozzle to smack into those. (I need a better securing in place but thats later until i get this fixed! XD)

sneakyferret

@jay_s_uk Thanks! What will this do exactly? (Very new, coming into all of this with learning in mind!)

jay_s_uk

@sneakyferret associates the fan correctly for when the slicer is sending fan on/off commands etc

sneakyferret

@jay_s_uk Duly noted, thanks!

@sneakyferret delete the config-override.g file as @o_lampe suggests. If the problem persists, please post your bed.g file.

@dc42 Thanks everyone! It's behaving much better now. Now, I start the fun process of correcting a funky height map which I may know already what the problem is. Thank you again.
