BLTouch V1.21

Anyone else notice that after 1.21 upgrade and changing probe type to 9 that during the homez sequence the BLtouch needle drops for a second time and then quickly retracts it? It doesn't cause an issue with the detection, but I now have two printers doing the exact same thing.

In other words it follows this sequence:

it deploys the probe
the bed moves until the probe is detected
the probe is retracted
the bed drops
the probe deployed and quickly retracts.

Hey buddy.

Mines always done this, but not all the time. On some probes it springs back up and stays there, on some occasions it pings back down again after a probe and retracts back again.

I'm using a clone BLTouch, but it's been the same for me from 1.18 firmware.

Ok, thanks for confirming I am not the only one coolice. Phaedrux, that link doesn't work.

Sorry about that. Bad timing. It should work now.
