@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.
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
@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.
@mendenmh Thanks. How would I go about changing this?
Dont know if it is also related, I have seen two different lines for M558 which one is correct and what does the 'H','R', 'A', and 'B' stand for?
M558 P9 H9 F120 R0.2 T18000
M558 P9 F100 H5 R0.2 T6000 A5 B1
@mendenmh When i home all axis it works perfectly. However, when I try to probe for mesh bed that's when I get an issue
@aidar Thanks.
I tested out the BlTouch and it deploys and retracts perfectly.
I then tried to do a mesh probe and it does the first corner but it only pushes the bltouch halfway back into place. It then proceeds to go round the rest of the corners without trying to test with the bltouch. It just pauses for a second in each place without lowering et.
The error I get at the end is:
Error: Z probe already triggered at start of probing move

@aidar Thank you. Yes, the black wire is an extension of the yellow. I changed my deployprobe and retractprobe files and it is better.
@aidar It is connected the same way it was before (see pics).
