Your M280 statements are incorrect. The P parameter is the servo index, not the pin name.
Also the M401 and M402 commands simply invoke the deploy/retract macros.

@fcwilt
Thank you very much for the reply!That seems to contradict the statement made in the M280 GCode Dictionary
"RRF3: Before you can use M280 you must create a GPIO port using M950. Then in the M280 command, the P parameter is the GPIO port number, not the logical pin number. Duet 2 supports up to 10 GPIO ports, numbers 0 to 9. No GPIO ports are allocated by default."
Am I looking at this the wrong way?
Furthermore, when I put
M280 P"0.io4.out" S10in the Console, the probe deploys.Is there something that I am not considering?
-
@charlie said in BLTouch Probe Won't Deploy:
when I put M280 P"0.io4.out" S10 in the Console, the probe deploys.
I checked the source, the P parameter reads the expression after P as integer, so P0 is read. The part after 0 is ignored.

No, the docs are simply confusing things by using two different terms (servo index, port number) for the same thing.
It not unusual to find the docs are a bit wonky in certain regards.
As to the other question regards the M280 working it as been explained by another poster.

Is that confusing? You must create a port number with M950 and then M280 uses that port number. What do you suggest to make it more clear?
It even shows examples

@joergs5
Thank you for your response. That's good to know. I changed the deployprobe0.g file toM280 P0 S10 ; Set servo position. ; P (Servo index): 0.io4.out (Mainboard, io4.out). ; S (Servo angle): 10.anyway, to avoid making the same mistake that I made between the GPIO port number and logical pin number.
The issue persists with this modification.
-
@fcwilt
Okay, that explains why theM280command worked even though I messed up thePvalue.With that said, Im still having issues deploying the BLTouch probe when homing the Z axis. The
M280 P0 S10andM401commands successfully deploy the probe. -
@charlie one issue in your config.g is, that the speeds are very low:
M203 S1 X300.00 Y300.00 Z15.00 E20.00
S1 does not exist for M203, so the speeds are mm/min, so e.g. Z is only 0.25 mm/s. So your probing might run into a timeout. Please use higher values. I would take the values of the documentation of M203: https://duet3d.dozuki.com/Wiki/M203
BUT: does Voron has a specific firmware, where S1 is valid? Then the firmware could be a reason for your problem, but I don't know how to help then. Which tool did you use to create the config file? Marlin and Slic3rPR use mm/s, but RRF use mm/min.
-
@joergs5
I assumed based on Duet3D Changelog: RepRapFirmware 3.3"The M203 command now supports an optional S1 parameter which changes the units to mm/sec. The default is still mm/min."
The X, Y, and Z homing speeds appear to be the same speed as I had before the change to S1. The probe just doesnt deploy during the Z homing step.
-
@charlie then sorry, it is not in the documentation yet.
I proceed searching for a possible reason...
-
@charlie homing is often made by homeall.g, can you please post it, and homex.g and homey.g also?
How do you home Z: individually X, Y, Z or together in one step?
-
@charlie said in BLTouch Probe Won't Deploy:
The X, Y, and Z homing speeds appear to be the same speed as I had before the change to S1. The probe just doesnt deploy during the Z homing step.
There are parameters to M558 to control probing speeds (travel and probing) including the ability to specify two probing speeds.
As another poster has mentioned you didn't post homeall.g which may well be why we didn't spot the problem.

No worries. I greatly appreciate your willingness to help!
In this case, I am homing X, then Y, then Z. With that said, the issue also occurs using the "Home All" button in DWC.

So homing just Z with the DWC Home Z button does not work? Just want to be sure I understand what is happening.

@charlie you may need to exchange the order or M950 and M558:
in the M950 documentation https://duet3d.dozuki.com/Wiki/M950 :
"M950 must come before any commands that refer to the device being created."
So M950, then M558 which uses the servo part of BLTouch.I am not sure about this. In the examples I know, M950 is first, M558 next, but the two commands don't have a reference to each other. But it's worth a try. M558 may expect to know the M950 values.
-
@fcwilt
That is correct. Homing just Z doesnt work.It also doesnt work if I use "Home All".
