G32 not probing the second and third points!

smoothie-forum
(trevor byers) #1

Ok so I have been trying to get my z probe up and running for a couple days now. I have searched and even found someone with an issue like mine but no answers on how to fix it. Anyways my problem is when trying to run the three point or even grid leveling it will probe the first point then slowly drop the bed a small amount with a horrible noise from the z steppers and then just fly threw the other points without leveling. I noticed with grind leveling the bed would raise up a little as it went along the points. Smoothie sees my inductive probe just fine and I’m able to get consistent results when jogging or homing. It seems as if the bed isn’t dropping down all the way after it finishes the first probe. So then the probe ends up stuck on and that screws everything up. I have no issues with my z steppers any other time but I still went and lowered the speed and increased the pulse time with no change. I have played with about all I can think of so now I’m hoping someone on here can help me out.

The is the readings I get from the probing. So you can see it thinks its at the 10mm probing height but its not.

To verify this wasn’t some issue with my probe I just wired up my old micro switch endstop as the probe with the same results.

(Arthur Wolf) #3

Hey.

You probably want to severely reduce both your slow and fast probing speeds. Try that and see if it helps.

Cheers.

(trevor byers) #4

Wow the one thing I didn’t mess with was slow feed rate because I figured it was already so low it wouldn’t be a problem but sure enough that was it. Set both to one just to test it out, Took forever with a 400mm but probed all three points. Now i have to inductive sensor hooked back up with slow at 2 and fast at 100 without any problems. Thanks you so much!!!

On a side not how does grid leveling work? I’m a mechanic and have zero clue what bilinear interpolation means or how it relates to bed leveling. Is it just a fancy three point that still just finds a single flat plane or can it account for the slight bow of my bed?

(Arthur Wolf) #5

Yep grid levelling is exactly for slight bows.
