Hot end not reaching desired temp

[truenorthtrader]

Hey anyone know why my Hot End is stopping at just under 232C most of the time?
Using all Stock Rostock Max parts.

It's been doing it a while no matter what I set the high temp as.
I did a PID tuning again but still the same.

I have the temp set to 234 but it goes barely reaches 232 / 231 but no higher.

The PID max value is 255 so it should go higher.
Any idea's?

thanks folks!

Your PID_Max controls how much current is allowed to get to your resistors. You would be looking for a max temp setting. I have never seen one, but I have never looked either.

Ahh thanks for clearing that up!

I'm beginning to think it's software related as after canceling a few prints it happens, but after I restart the computer it works again until I cancel a few prints.
It's just a minor annoyance I'll see on the next update if it stops or not.

increase your P slightly, decrease your D or I slightly, the PID setting is probably just over damped.

Thanks yet again Polygonhell! I'll try that today!
all the best
