Update: I set $1=255, which didn’t change the behavior. I then tried $27=0 (it defaulted to 3 which is, I guess, where the 3mm bounce or “pull-off” was coming from). After that, when I home, the head just stays jammed up against the limit switch and requires a laser reboot in order to be able to connect again. So, I had to take it back to default.
Would one of the settings in the attached screenshot help with this issue?
Thanks again!
