G30 oddities "probe already triggered"
-
I have read many threads and thought I had pieced together a functional bed.g for this printer. It has 4 ballscrews (another venerable Dowell3d conversion). I actually used the original dowell conversion config to get me this far.

G30 P3 X20 Y756 Z-99999 S4 ; probe near a leadscrew and calibrate 3 motors BLAt the last probe point, it just deploys the bltouch probe and retracts it immediately with no movement. Mind you, every bltouch probe worked up til this point. The message is "probe already triggered" even though the bed is well clear of the probe.
Thank you for your assistance.

The first thing I would do is add B1 to your M558 command so that the heaters are turned off during probing.
The BL Touch is susceptible to electrical noise from both bed and nozzle heaters. -
was loose wire.

@thetazzbot
That'll do it
