Hotend alarm heating to slow

@fcwilt
Manually in duet 3 web interface. Use drop down and put to 200 and activate .When using the auto tune it's m303 to m205 command and it runs all 4 tests. I gave you the last results that I put in the config.g and replaced it with the old one in there.
The test runs fine and goes up to 205 3 times with no issues.
Only fails when I do it manually or upload a gcode file to start a project.
Stupped why it works on auto test but not anyother way. It must be disabling something to run the test that's stoping it from normal use.

@ecnsupplies it looks like you replaced you bed heater M307 with the one for your hotend. So now you’ll probably need to tune your bed again, unless you have a backup.

I have a backup. And the bed works fine. Just the hotend gives the error.
It's so close to getting to 205. Makes it to 185 in a min. Before it fails. -

Added M570 H1 P4 T15 in config file, shut down, waited 2 minutes then turned back on
It did not help! Same error at 183.6 deg. -

Swapped the m307H0 R0.532 K0.167:0.000 D13.56 E1.35 S1.00 B0 added it to hotend and put back the bed defaults all working! thank you -
Glad you got it working.
Just FYI the parameter P4 is less than the default which would be P5.

Ok. Will change that.I checked a couple of my printers and they were set to P300 - that is very large and I have no recollection of why I did that. It doesn't seem right at all.

switching to 24v power unit resolved the extremely slow heating issue
Was it a 12v power supply before? What voltage are the heaters rated for? Running 12v heaters at 24v is dangerous.
