Looks like you should start reading here : https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_Set_Z_probe_type

@mendenmh Thanks. How would I go about changing this?

Some more reading will help: https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe

@aidar thanks. It is always good to refresh myself on that. That helped alot.

The one remaining issue I have is that the probe goes down on the first location on the bed. Then it goes to the next, and deploys the probe it then doesn't retract. It will then just go to the positions and not try to probe. It then gets an error. If I manually lift the probe after it then goes to the next location and the same thing happens.

After this is done, the bed is not leveled at all.

What are you using for your M558 right now?
Do you get any error messages in the console?

Elliot

@Phaedrux

The M558 I. Am using is:

M558 P9 H5 F120 R0.2 T3000

The error I get is:

Error: Z probe already triggered at start of probing move

What do you have in your deployprobe.g and retractprobe.g files?
Please confirm that you have none of the following commands in any of your homing files or in bed.g:

M98 Pdeployprobe.g
M98 Pretractprobe.g
M401
M402

You can send M401 and M402 manually to test whether probe deployment and retraction is working, but you should always start with the probe retracted before running a command that does probing.

@dc42 Thanks. All worked out in the end.

Seems there was something physically wrong with my bltouch.

when testing it out a few days ago it didn't retract properly and got bent. I rebent it and now everything works perfectly. must have been stuck inside and this unstuck it.
