Thank you very much for your help. I changed the M84 in the config.g file to 20 and all is well. Please mark this resolved and again, a big thanks for the quick response.

Hello everyone,

I have been printing with my Duet 3 powered corexy for a couple of weeks and now I am having a "loop" where when I try to home, it resets to an unhomed state upon homing. If you do a single axis it does the same thing and flashes homed and then resets to unhomed. No errors on the console reported.

Short video of the homing issue:

I switched from out3 to out7 and mapped it per config file below and it works. I am not sure why but at least the chamber heater works now and I was able to tune it.

I tried to tune as you suggested:

The SSR has an LED that lights when it is activated and it didn't turn on during tuning. It will activate if I supply voltage to the terminals so I verified it works.

I am trying to get my chamber heater working on my Duet 3. I am using an SSR and if I provide the SSR with voltage it triggers and the heater works. When I try to activate it with DWC, it just faults because there is no change in temp and I get the rising too slowly error.

Here is the relevant section of my config file on the chamber heater:

M308 S3 P"temp3" Y"pt1000" R2200 ; configure sensor 3 as PT1000 on pin temp3
M950 H3 C"out3" T3 ; create bed heater output on out0 and map it to sensor 3
M141 H3 ; Define heater h3 as chamber heater
M301 H3 P-1 ; Disable PID settings to use bang-bang
M143 H3 S150 ; set temperature limit for heater 3 to 150C

I am using Duet Web Control 3.1.1. Note the temp is correct and reflects change if you manually cycle the ssr.

Any suggestions would be appreciated.

Thanks,

Mark

You nailed it. I had a change in my starting script for simplify that fixed it once removed.

Thanks for the help and mark this solved.

@Phaedrux

I cannot run any new files regardless of the name. Only files previously printed. If I attempt to print it just gives the same error. I have tried this multiple times.

The file is really named t.gcode.

It was just a test print file to see if the problem repeats. Every file try to print now fails to print with the same error.

Here is the file

t.gcode

It is duet 3 with sbc: FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet 3 MB6HC v0.6 or 1.0 FIRMWARE_DATE: 2020-05-19b2

Thanks,

Getting an error now whenever I upload a file to print. old prints previously loaded can run:
