3.4rc1 Mini 5+ bltouch not retracting

For good measure can you share your config.g, and the results of M122?

In 3.4rc1 the probe now deploys but doesn't retract after probing.
Machine was completely powered off after the update.

Further debug...
I replaced my bltouch with a multimeter set to measure frequency and duty cycle.
Reset the board by pressing the reset button
Measured 0% duty
Sent M280 P0 S90
Measured 7.35% duty at 50Hz
Send M280 P0 S180
no change in measurement
sent m280 P0 s270
no change in measurement.
reset board.
sent m280 p0 s270
measured 12% duty at 50Hz
sent m280 p0 s90
no change in measurement
Thus i think my issue is the same as this thread:
https://forum.duet3d.com/topic/27139/rrf-3-4-0beta7-5-sbc-servo-only-responding-once-after-reset

With 3.4b6
Reset the board by pressing the reset buttonMeasured 0% duty
Sent M280 P0 S90
Measured 7.35% duty at 50Hz
Sent M280 P0 S180
measured 12% duty at 50Hz
Send M280 P0 S270
measured 12% duty at 50Hz
Sent M280 P0 S90
Measured 7.35% duty at 50Hz
So updating servo positions multiple times in 3.4b6 works

@serbitar I can confirm that this is a bug in 3.4.0rc1. It affects the use of port IO1 on the Duet 3 Mini to connect a servo or BLTouch, but not IO2 or IO3. Are you able to use either of those ports for now? Note that IO3 is shared with the 12864 backlight control.
-
Ah! I will sacrifice one of the runout sensors to put it on io3 and give it a go, thanks.
-
Works great on io3 thanks again.
-
@serbitar I've put corrected firmware for the Mini5+ at https://www.dropbox.com/sh/hx23neagiljflv2/AADxC8_URWgoU_NYcYP8b7XCa?dl=0.
-
bltouch back on io1 with your updated build works. fantastic! thanks!
