Trouble with Config and Auto Tuning the Heated Bed
-
Can someone help me figure out how to auto-tune my heated bed? I've tried using the M303 H1 S220 command and nothing happens. I currently have my heater setup on H1 instead of H0. Ideally I would have the heated bed setup on H0 and the extruder heater on H1 but I was unable to get that to work in the past for some reason. (config below)
On the delta printer I have an FDM tool setup as T0 and a laser inspection tool setup on T1 and a heated bed.
Also how do I post a config file in the forum so it is contained within its own window?

That may be the root of the problem.
Do you see a temperature in DWC for the tool and bed heaters? Does it increase at all if you set a temperature?
How do you have the heaters wired?
What kind of heaters are they?
12v or 24v PSU?
Is the bed AC powered?
Please send M122 and M98 P"config.g" and post the results for us.

In the post window there is a little button that looks like this </> click that to get a code block. Paste your code into it between the ``` marks

Yes the tempertature for the Deposition Head (hotend) is increasing just fine.
The hotend (24V 40W Heater Cartridge) is wired to the "E0 Heat" pins. The Bed Heater is a 120V heater that is powered by AC which is wired through an SSR that is controlled from the "Bed Heat" pins. The PSU for the controller is 24V.

Ok, when you try and turn on the bed heater, does the LED on the Duet and SSR turn on to indicate it's on?
What kind of SSR is it? How do you have it wired?
Let's also go back to a more standard configuration.

Send M115.

Thanks for your help. I cleaned up the config and also learned that the fuse block had a bad connection in the AC loop. Now everything is working.
Yes, both the Heated Bed and SSR LED's are turning on.
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.2.2 ELECTRONICS: Duet WiFi 1.02 or later
FIRMWARE_DATE: 2021-02-11On another note, often times when I try posting to the forum I receive this error. What's the best way to overcome this?

May want to update to 3.3. Upload this zip file to the system tab in DWC.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zipAs for the forum error, that's not a great error message.
I would suggest trying a different browser or clearing your cache first.

@code7 The forum error I get from time to time. Easiest fix is to copy what you had tried to post. Cancel out of posting. refresh your browser and then post a message pasting from the clipboard... Seams to happen the most with chrome based browsers. (I use brave).

I've seen it myself rarely. Only on mobile though.
