@frnknstn In homeall.g I don't see a G30 to use the probe also you want to go absolute to Z = -200. I might have missed something.
What happens when you just run homez.g? (turn you steel plate upside down to protect the pei)
Is your Z going in the right direction?
Also, you don't have a Z-switch (nozzle probe) do you?
-
@gixxerfast no, i tested homez again, it does what i said previously.
-
@frnknstn another thing as it is slowly rising up it looks like the left rear motor is moving a little faster than the rest
-
@frnknstn said in z probe help if possible:
@gixxerfast no, i tested homez again, it does what i said previously.
Yes, but if you manually run Z up and down with G1. Does it go in the expected direction or do yo have to invert the motors?
Also, your probe config is a little bit of a mess. Have a look here and go through your config.g and homeall.g and homez.g and try do make it look a bit more like this one.
Skip the pullups in the example config though -
@gixxerfast imy z does look backwards. +10 brings the gantry down to the table. -10 opposite. I will switch this to start
-
@frnknstn Because, your homing config looks like a mix of endstop config and probe config depending on which file you look in. Also in config.g you have, as I see it, a lonely G31 down by the heater definitions.
So, it's better you take a grip on it and follow an example, like the one I linked, and go from that one.
