BLT Manual deploy +HomeZ ok ~ Auto HomeZ = no?
-
For some reason, I can't seem to get my BLT working as expected. I followed the online example for wiring, Config.g et al, but I have something either transposed or wrong. Can someone take a look and see if anything sticks out?
FYI - It seems to be wired up correctly. The probe will not automatically deploy when functioning as a Z end stop/Zzero switch. However - If I manually deploy the probe via my 'deployprobe' macro, it does in fact deploy & if I command the Z to home, it does in fact work as expected. Just not sure where my code is messed up.
Yes...there's cleanup to be done deleting extra comments in the code. Thank you in advance for looking...

Sorry but I don't understand what that means.
What do you do to make it work, and what do you do when it doesn't work?
Does sending G28 (homeall.g) work?
If you send G30 does it deploy the pin?

;M98 P"^deployprobe.g"
M401 P1; Lower Z probe (BLTouch)
G30 ; home Z by probing the bed
M402 P1; Retract Probe
;M98 P"^retractprobe.g"Remove all that deploy retract cruft. It just needs G30.
Can you send M122 and M98 P"config.g" and share the results?
-
Basically, If tell it to HomeZ (after homing X & Y individually) - it runs the nozzle into the bed.
However...If I deploy the probe pin and then run homeZ, it works as you'd expect. It touches off twice and raises the Z up. It does not retract the pin though...I have to do that manually.
Not running home all until homeZ is good - for obvious reasons.
(More on the other stuff you asked in a few min...)

If you send M401 and M402 does it deploy and retract the pin?
If you send G30 does it deploy the pin?

No, that's for RRF2.
-
That's a negative on all 3 counts.
However, If I click on my deployprobe macro, it deploys. Clicking on retractprobe macro, it retracts.
-
Where are those macros? They should be in the system folder
-
@Phaedrux Wow dude...You rock! That was it!
I thought I uploaded them to the System folder...not sure where they got loaded to. The Macro folder?
HUGE THANK YOU!
