Voron 2.4 new TAP - Z end stop or Z probe config ?
-
Hello Gents,
My Voron 2.4 x 350 is starting to move.
Please can I ask for clarification on the correct config for the "TAP" Z end stop, and Z probe config settings?
I tested and confirmed iT IS working correctly using M119
In the current open position, M119 is - Endstops - X: not stopped, Y: not stopped, Z: no endstop, Z probe: not stopped.
When I try to home Z the error immediately reported:
"Failed to home axes ZG1: Failed to enable endstops"
How can it be "Failed to enable"? I can not set Z end-stop and Z probe to the same C"io3.in"
My config section is
;+++++Endstops M574 X2 S1 P"io1.in" ; configure switch-type (e.g. microswitch) endstop for high end on X via pin io1.in M574 Y2 S1 P"io2.in" ; configure switch-type (e.g. microswitch) endstop for high end on Y via pin io2.in ;+++++Z-Probe M558 P1 C"io3.in" H5 F120 T6000 ; set Z probe type to switch and the dive height + speeds G31 P500 X0 Y25 Z2.5 ; set Z probe trigger value, offset and trigger height M557 X40:260 Y40:260 S20 ; define mesh gridFirmware is all up-to-date:

@KCMARINE it should be setup as a probe.

your Y offset it incorrect. It should be 0, not 25

How can it be "Failed to enable"? I can not set Z end-stop and Z probe to the same C"io3.in"It's failing because you're likely trying to use a G1 H1 Z endstop move when no Z endstop exists. As Jay says, the voron tap should be used as a probe, so instead of G1 H1 Z moves, you would need to use a G30 to initiate a Z probe movement.

Thanks for the help, moving forward with your advice I am now able to successfully home X - Y and Z using the G30 command in the homez.g file.
The issue I am now facing is that once Z is homed, it will only move in the negative direction - I can not get it to move in the positive direction!How do I clarify that Z = 0 - my understanding is it thinks Z = 355mm?
I also see my next mission is figuring out tramming the gantry and bed mesh calibration - any pointers greatly appreciated.

It still doesn't look like you've changed your files.
G1 H1 Z255 F360 ; move Z up stopping at the endstop G90 ; absolute positioning G92 Z250 ; set Z position to axis maximum (you may want to adjust this)The G1 H1 move needs to be replaced with a G1 X Y move to position the print head, and then a G30 to use the probe.
Then you must also remove the G92 Z250 command because that would override your probe result.

@KCMARINE you need to make the same changes to homeall

You would get insufficient axis homed error in home z if you try and run it without the x and y axis already being homed.

Thank you for your help Gents,
I managed to now get X Y and Z homed - for any other people facing this problem in the future, this is the code that worked for me:

Thanks again

You may want to add a G1 X Y move before the G30 to position the print head where you want to probe. Typically the center of the bed is used.
