Error: Bad command: Probe deployment routine for BLTouch
Error: Bad command: Probe deployment routine for BLTouch
Error: Z probe already triggered at start of probing move
Error: G0/G1: insufficient axes homed

Those messages indicate a problem in your deployprobe.g file. Please post the contents of that file, also the contents of retractprobe.g.

I used the ones from the BLTouch post. So I did get somewhere today. It is very hard for the first time.
But I didn't give up. I love the board.

Now I am starting to understand I found I post about deployprobe.g retractprobe.g meshing. So now I have it meshing but don't fully understand it yet but it is running trying to mesh now. I have to keep reading more.

This line is a comment so it should start with ";"

dc42

As @denke says. Also I think you are running a file, maybe called meshlevel.g, that has a similar problem (comment line without a ':' character at the start).
Which firmware version are you using? if you are using 2.0RC5 then the "Max open file count exceeded" message may be caused by a known bug in that version.

I am running 1.21 should I update it.

dc42

No, stay with 1.21 for now.

I found this post and tried this it worked now the bltouch doesn't stop the head it crashes into the bed.

I tried what you told lazy_mosquito in this post but it didn't work.

The first thing you need to get working is a basic G30 move without parameters. See https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe. In the case of bltouch, when you send the G30 command the probe should deploy, then it should move towards the bed, and when you push the pin up it should stop.

I have been reading and trying everything I can find. I home X & Y send the head to middle of bed. Then send the G30 and this is the only error I get. G30 Error: Z probe already triggered at start of probing move. Red LED on to center of bed as soon as I do the G30 only the blue LED but no movement.

You should not use parameter I1 in the M558 command for bltouch. That explains the error message you are getting.
The XYZ parameters in the M558 command are no longer valid or required, and can be removed.

For some reason I have to use heater pin 7 not heater pin 3.
