Configuration Z-Probe
-
I want to say I had to add something to my homeall.g in order for the z probe to work. Before I added it the z probe would show its working but during homing it wouldn’t actually stop z movement.
I don’t have a delta but I’m just guessing you need to add it also. When i get off work I can look at my homeall.g to see what I added.

I can find the gcode... but i haved a idea...
CHECK IF Z-PROBE WORKS
How?
See https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.
-
@stealthy_tt Thanks
-
Think... that this can't use it....
i'd like check if Z-Probe stops the movements, with calibrate...no stops... but i wat check if, with normal movements, G1, the zprobe stops the head movement. I have cheked, that Z-Probe(Mini Ir) is reconiced by Duet, when i close some object to Mini IR, in DWC, can see how the field Zprobe raises until 46x... but.... when i calibrate the printer... and trigger Zprobe, dont stops the movement....
For this .... i want check, with G1 flag, in Zprobe is well reconiced...
Its supposed, with cartesian printer type, if gcode, G1 Z-200 S1, move the head 200 mm downwards, if Zprobe its triggered, the movement must stop. No? but with a Delta printer, this flag S1 don't work.... There is similar flag for a Delta?
-
You are confusing an endstop switch with a Z probe. G1 S1 commands are for use with endstop switches, not with a Z probe.
-
And iirc s2 is for z probe right? I’m not home to check my config for it but that’s what I believe i set for mine.
-
To use a Z probe for Z homing, use a G30 command, not a G1 S2 command. See the first item in https://duet3d.dozuki.com/Wiki/FAQ.
-
You are correct but I’m sure you already knew that haha. I have a g30 command in homeall.g
-
Hi,
after some test... i have cheked when i send G30 S-1, and put an obstacle in ZProbe.... *** STOPS THE HEAD MOVEMENT***... this discards a fault to Zprobe, and bad conection....
IF:
- When printer power on, ZProbe blinks correct.
- When by console send G30 S-1, printer head stops with a obstacle
- When try calibrate, Zprobe DON'T stops printer head movement...
Why?
A- Something is wrong in bed.g?
B- Something is wrong in config.g?
C- Le falla "lajuntadelatrocola"What can i do?
Latest test are made with Mini IR

-
@peirof why is there a * on the s6 param on the last line ?
-
Hi,
In homedelta.g... it's mecessary place code? Homing a Delta, there is with endstops, No?...
Delta dont use Zprobe for Homing. No?
-
@peirof No delta doesn't use the Z Probe for homing.
-
eee... i have try to put that text in Italic, with forum web app... but dont reconised...
the *, there isn't in bed.g...
-
@peirof OK it just looked strange!
-
Please test the Z probe with a G30 command as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.

@dougal1957 said in Configuration Z-Probe:

Makes sense, like I said above I don’t have a delta. Now I know.
-
@stealthy_tt yeah on a delta it always homes to max Z so the probe can't be any further away from the bed if you tried but if you've never had one then you wouldn't know that fact
-
Hi... I haved do these test, send by console G30 S1... and zprobes WORKS.. Míni Ir and Bltouch.... But calibrate dont works
-
What test i can do for discard problems?
So far, from the tests I have done, I think two things can be ruled out:
1- That the z-probes (both BlTouch / Mini IR) are damaged
2- That is a problem of the wiringIt seems an error in the configuration .... but I have checked it several times, and it seems that everything is fine ....
One test I can do is change the firmware, although I do not think that's the case, since the Z-Probes, were working with this.
