Unstable temperature

 Hello everybody,

The nozzle temperature is really unstable. It swings between its set temperature and way lower temperatures, as is shown in the picture. It seems like I can only print without clogging the nozzle due to too low temperatures if I set the nozzle temperature at 225. Has anybody experienced this as well? I tried to alter the PID settings already following one of the manuals on the website but that did not help. Also, in a support ticket it was told that I should update the firmware but it gets stuck during uploading every time. I hope somebody can give me some remarks on this as well as the customer service is not really helpful at this point.




I'm having the same issue i want to make change to the firmware but every time i try to upload the sketch it gives me a time out error.

Have you tried updating the software and firmware so you have the latest PID settings as well?

1. Update Creatr HS/ HS XL/ HS Lite Stand-Alone Software

2. Flash New Firmware on the Creatr HS/HS XL/ HS Lite

3. Set extruder offset for your CreatrHS (M50)

If this does not work it could either be the thermistor which is not working properly or a damaged heat cartridge. What I would suggest is swapping the left and right hot end and heat cartridge and see is the issue moves to the left side or not.

In the end, I increased the D of the PID to a very high value and that worked.
