Hotend heating issues but only with Klipper

General Discussion
1

Basic Information:

Printer Model: Ender 5 Pro
MCU / Printerboard: creality 4.2.2 “GD chip”
Host / SBC raspberry pi 5
klippy.log - not available at the moment. will update

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

When running Klipper the printer cannot complete a PID tune above 150 deg. Anything above that and it fails. If I try to print it will start as long as my temp isn’t over 200 deg and will run for a little while but then shuts down with the “heater not heating at expected rate” error.

However, if I run marlin, i can PID tune as high as 230 deg and I do not have any errors.

I thought it was faulty temp sensor or heater cartridge at first but since they work with Marlin, I assume is some software issue somewhere.

Anyone else have this issue ?

Thanks,
Brian

Agree to @theophile .

The way you did, spaces and special characters are lost and the data is not usable.

Sorry, here is the full log. I just tried a pid calibrate again.

It looks like there is something wrong with your heater, to make sure I’m not reading this wrong…

Is it taking like a minute or so for your hot end to reach 215 degrees?

If so, what is your hot end and heater type? That’s absurdly slow.

This is a stock ender 5 with creality 4.2.2 board and stock hotend.
That is what I initially thought as well and it may still be the case but when I run marling it seems to work just fine. I can complete a pid tune at 230 deg C. So that made me think is some wierd setting or software glitch with this board and Klipper. This board has the GD chip in it as well.
I guess worst case I’ll but a SKR mini e3

So wait, Let’s go in order.

Which of these order of events is correct?

A.) You were on Marlin, switched to Klipper, Now it doesn’t work.

B.) You were on Marlin, switched to Klipper, it didn’t work, switched back to Marlin and it worked again
