Its a capacitive sensor probe. Sorry, the clicking is the relay.

My zprobe will go nuts (clicking) when printing sometimes. Specially when going over a printed area. Is there a command to turn off and on the zprobe. Could put at end of start code and end end code to turn back on.

The temp I had it seemed to be too low. Tower at temp 205 and below fell apart. 210-220 worked the best with 220 being the cleanest.

I did the extruder calibration and once calibrated it seemed to be dead on.

Hatchbox 1.75 PLA

From Cura:
Printing Temperature 200
Printing Temperature Initial Layer 200
Initial Printing Temperature 190
Final Printing Temperature 185

Printing a temperature tower to check the temps for this new roll of PLA.

Well the print looks 100% better. Still have a little adhesion issue at the half way mark. But the size is about spot on.

Yah. I was looking at the duet page and didn't find it. Googling I did find it. I am calibrating it now. Figured out why the print shifted. For some reason the gear screws on the X & Y motors came loose and it was slipping.

How do calibrate it? I can't find any instructions

So I went to the my first print and I chose the Cube.

I am using Cura 3.5.0 for the slicer. It seemed to start out great but then thing went horribly wrong.

The first few layers look correct then it just started shifting. Then is just decided to move to a different location and print.

Here are my Cura settings for the printer that I added:

I am so close I can taste it. Any idea what I am doing wrong.

Yah figured it out. Was doing the mesh compensation. When I looked at the mesh it was really bad and all over the place. Long story short the fan cable was too close to the probe and it was registering all the time. LOL. Quick fix and now the test print it laying down correctly.

Thanks for the help!!

Yah, It seems to be working now. Save using an M500. Now trying to do a first print. The Z says 0.3 but the nozzle is a good 5 mm above.

It curve starts out vertical because of the 12V heater cartridge. Also, Overshoots about 30 degs. because the voltage is doubled. Found a 24V cartridge in my box of misc parts. The curve is more gradual on heating and now I get a different warning.

10:43:35 AM Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 514C.

Just ordered one. Thanks for the help.

Makes sense. It is getting to temp really really fast. So if I have a 24V PSU how do I get 12V to the hotend? I have a 24V to 12V converter but I wouldn't think it could takes 4 or so amps. Do I need a 24V cartridge?

I have tried the following:

All of the temps I have tried have 3 different temps with the same result.
Am I doing something wrong?

That did it!! Thanks for you help.

Also, Here is my Z-Probe config from the config.g

; Z-Probe
M574 Z1 S2 ; Set endstops controlled by probe
M558 P5 H5 F120 T6000 ; Set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z2.5 ; Set Z probe trigger value, offset and trigger height
M557 X0:290 Y0:290 S20 ; Define mesh grid

So I checked the relay wiring again and everything is wired correctly. It also switches and provides 5V on the output side when triggered. I removed the Z_PROBE_IN line and checked and it is showing 3.3V on that pin. Why is that? I thought this was an input pin.

As you saying remove the relay and just add a resistor to the signal cable which goes to Z_PROBE_IN. Just noticed that when triggered the voltage on the signal line of probe is .0003 and when not triggered it is 24V. It is suppose to be a NO. Figured it would be the opposite.
How would I activate the signal on no voltage.

I decided to use a "1 Channel 24 V Board Protector Relay Module with Optocoupler High Support and Low Arduino Trip Level" board. I took the 5V from the "Always on Fan" for the common to send the signal to the board. Now if I just seeing it as always triggered. In the configurator I selected the Z-Probe Type Switch. The 5V being sent from relay is only on when probe is triggered. But board seems to think it is always triggered. Any ideas?

Does the Duet WiFi 1.04 with a capacitive Z-Probe sensor require an optocoupler module? The documentation states that you can just hook up the ground and signal wire as usual and then the power to VIN. Wouldn’t the signal be 24v (using 24v power) when high and thus require an optocoupler? Unless the Duet is taking the signal to a workable range for the board.
