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.



Regards,


Marcel

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.

Filament Guide

ABS
  • Extrude at ~ 225o C.
  • Requires heated bed.
  • Works reasonably well without cooling.
  • Adheres best to polyimide tape.
  • Filament tolerances are usually tighter.
  • Prone to cracking, delamination, and wraping.
  • More flexible.
  • Can be bonded using adhesives or solvents(Acetone or MEK).
  • Fumes are unpleasent in enclosed areas.
  • Oil Based.
PLA
  • Extrude at ~ 180-225o C.
  • Benefits from heated bed.
  • Benefits greatly from cooling while printing.
  • Adheres well to a variety of surfaces.
  • Finer feature detail possible on a well calibrated machine.
  • Prone to curling of corners and overhangs.
  • More brittle.
  • Can be bonded using adhesives.
  • More pleasant smell when extruded.
  • Plant Based.
