Sry, this was too easy and I gave up before I needed to. I found this code and am running it now...

m303 h0 s100

@fcwilt Thanks for the input. I tried copying code on my phone yesterday and the forum gave me an error. A friend suggested that I run m119 in the console and it showed the z stop as being off. I looked over the wiring this morning to discover that the z probe cable was plugged into the wrong spot on the Duet. Problem solved.

I am trying to suss out my Crealty CR Touch, but I'll start another thread on it when I'm ready for input.

@jrcl Again, thanks. It has finished the auto-tune and gave me this message:

Auto tuning heater 0 completed after 3 idle and 5 tuning cycles in 998 seconds. This heater needs the following M307 command:
M307 H0 R0.532 K0.167:0.000 D13.56 E1.35 S1.00 B0
Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.

I didn't see a "V" parameter in that line of code and am not sure what VIN means in this context, in any event. I easily found the line of code in my config.g and have replaced it.

Thanks to everyone here the printer is printing... I am waiting on terminals to finish the CR Touch install and I'm pretty much ready to play with it.

@jrcl Does VIN stand for Voltage In, then?

@jrcl Thanks... I think I missed a "u" argument which would have used the result, so I might have to rerun it or go your route.

m303 h0 s100

Perhaps this is a "PID Tune" issue, and if so, how do I do that?

Whenever I start my bed heater I get Error: Heater 0 fault: temperature rising too slowly: expected 2.30°C/sec measured 0.57°C/sec

How do I change this value? Do I need to change the heater?

This is a 120V bed heater running through a solid-state drive. It is giving 120V to the heater.

@stephen6309 & @fcwilt thanks to both of you... that really helps a lot. My mod wire needs to be connected to exp HEATER3. "exp" means expansion header. Cool. Simple enough to do.

Now, how do I define HEATER3 as the real "Mod"? Do I have to edit config.g and add it somewhere?

@fcwilt and @Stephen6309 It's a big doc with lots of illustrations. Can you be more specific with the pic you want me to see? Maybe post it here? I'm just a noobie and a bit overwhelmed. but I'm really trying.

The documentation says "9 BLTouch OUT (Duet 3) and MOD (Duet 2 Maestro) can be configured to control deployment/retraction. MOD on Duet 2 WiFi/Ethernet is not PWM capable, so use heater pin on expansion port instead." I have a Duet 2 WiFi, so please translate.

@fcwilt Thanks for the quick reply...

This is the photo of the CR Touch going into a Crealty board... it's the only pinout of the wires I could find for it. The only difference is that it says "out" instead of "mod". Other than that, I think I have wired it just as a BL Touch. Do you have a specific wire you think is wrong, or was that just a general comment?

Someone has mentioned that the CR Touch is a clone of the BL Touch. That assumption could be the real problem.
