BLTouch Homing in wrong direction
-
If the exclamation point to invert doesn't work, might need to change the pin name
M950 S0 C"duex.pwm5"also might need to be inverted, but I'm not sure. I've never seen anyone use the breakout board for the BLtouch, so until I get some confirmation we'll just have to experiment. -
seems inverting pin may have worked deploy macros now working

used multimeter to prove continuity between the pins on idc ribbon cable and heater pwm pins
OK then I think at this point you may just want to try the various other names.
exp.heater3, exp.8, !duex.e2heat, !duex.pwm1
exp.heater4, exp.13, !duex.e3heat, !duex.pwm2
exp.heater5, exp.18, !duex.e4heat, !duex.pwm3
exp.heater6, exp.23, !duex.e5heat, !duex.pwm4
exp.heater7, exp.31, !duex.e6heat, !duex.pwm5I have the Duex5 board and this is my command M950 S0 C"duex.pwm5"

That's good.

any advice on how to reduce how close nozzle is to bed currently
G31 P25 X46.5 Y0 Z3.6
do I change the 3.6mm height?
-
Follow these steps to measure the trigger height
Then afterwards when testing your first layer use the baby stepping function to adjust. Then take the amount of baby stepping used and modify the G31 Z value.
A larger G31 Z value moves the nozzle and bed closer together. If it's too close, make G31 Z smaller.
-
so reduce the 3.6 to like 3.4?
-
bedlevel_nozzle_0.4_200x200-0.3-0.8.stl
I'd suggest printing a test pattern like this and adjusting the baby stepping to find out exactly how much to change it.
But yeah, 0.2 sounds like a reasonable amount to start with.
