@kevinlallshouse @kevinlallshouse Try removing the ! from this line.

M558 P9 C"^!zprobe.in" H10 F120 T6000

Try these commands also

If the probe needs to be deployed before use (e.g. BLTouch), test the deploy and retract functions, by sending M401 to deploy the probe and M402 to retract it.

When the printer is powered does it do the init sequence? out / in, out /in?

What exactly doesn't work? Or what does work?
What happens when it's powered on? Does the pin drop and retract?
Does the BLtouch light up?
Does M401/M402 work?
Does sending G30 cause the pin to drop?
Does touching the pin stop the Z axis?

kevinlallshouse

so i got it to all work and ran my bed calabrations but when i run a print z axis homes then raises and drops back down in to my bed on the second drop. i have a 30mm x off set for bl touch and it works on the first home do you think i need to put in another offset for the second drop? any ideas were to start?

Phaedrux

Post your current config file, homing files, and bed.g file.

kevinlallshouse

thank you I got that issue figured out and I'm on to another issue unfortunately but thank you for your response.

What was the problem and how did you solve it?

kevinlallshouse

ended up it was in my cura gcode there was some marlin in there and once deleted its been running fine now thank you again.
