Nozzle temp will be rock solid, until the side fan kicks on at >50%. then it drops from 220 to about 112 and then bounces around a bit until it steadies.
However, many times, the printer will error out claiming nozzle issue.
If I manually watch he side fan and “ramp” it up slowly, the temp stays fine and no printing errors.
My fan labels are completely different. I am printing right now so I cant show them. I do see I am a few versions behind in my creality print software, so will update it .
This time when it rebooted and I Resumed, I turned the fan on immediately so that it could stabilize at the right temp with the fan running, instead of the fan starting up later.
But as the head moves close to the side fan, the temp starts to fluctuate again.
Okay. You are using Mainsail with the K1. I was mistaken. I thought without further questioning you that you had a K1C with the GUI from Creality. A-Okay…
There was also some talk about people doing a calibration for the heater. Maybe something to look into…
So, with Klipper and Mainsail, one would and this is for boards I am familiar with currently and not the K1 board for Mainsail, I would follow along in Klipper ideals…
I know nothing about the K1 and using Mainsail with it
PID_CALIBRATE HEATER=heater TARGET=230
That should calibrate your hotend heater if it is available on the K1 at 230 degrees C
If that is not available on the K1 and/or your HEATER=heater is called something different, do not try number 2.
If and when your GUI from Creality (I am guessing here) allows for it, calibrate the heater element so that the heater knows where it should gravitate towards.
I remember using Mainsail a bit with another controller. If things are properly set up in the config and if things were Open Source with Creality alongside Klipper, one could easily tune the machine to a working order…
Klipper uses some type of Macros:
You can view how some of their buildings are put together and how to incorporate that into your build. Will it work? No clue. Time will tell…
But…
I say if it is broke, fix it. I cannot guide you 100% of the way but I will say these ideas…
K1C uses Klipper (I think). I have not researched the ideas in about two months.
K1C adaptations have changed and quickly. For instance, from 4.x.x to 6.x.x in about two months time.
So, someone is purchasing these machines and making them work and well.
I have the K1C. I got tired of waiting for prints to finish and I splurged. I saw their other series but I cannot afford to handle the price tag. So anyway, I hope you can configure your board firmware so that your GUI does as expected, i.e. not as shown. If you need other ideas, please just jump on in and let me know what exactly is available on the Mainsail screens or I may just interpret them incorrectly.
For instance, read the klipper docs on specifics. I know the, or knew, older 4.x.x version had klipper but their flavor of klipper installed on the machines and that is as far as I made it…
I took the entire machine apart, acted like it did not work, and then just went with what they offered. I made a simple workaround useless because I quit. I flashed the machine and then barreled over and just upgraded to their OTA firmware(s) available. I work with it and with them now instead of going against their build process.
