The clicks of the motors on the K1C

I bought 3 K1C printers that have been working hard for 4 months, but a couple of days ago all 3 printers started clicking motors with printing gaps, the problem is clear and understandable - the rod is stuck or something prevents its supply in the feeder. But after opening all 3 feeders, no problems were found, as with the motors

  1. Replaced the feeders and motors on all printers with new (Original) ones
  2. Put new nozzles for a cleaner result (0.4)
  3. Rechecked the slicer settings
  4. Updated the firmware to version 1.3.3.8 (1.3.3.5 was installed when buying
    (Printers were not rooted!)
  5. Used a filament of different brands and materials
  6. There were no problems with the mains voltage, there is a voltage stabilizer 220 on the network to which the printers are connected

The problems with clicks and skips have not gone away. On one of the printers, clicks appear steadily on 2-3 layers of printing.
What could be the problem?
There is an assumption that the problem is in the voltage applied to the stepper motor, but at the moment I have not yet tested this hypothesis.

Please see my to do maintenance on K1c problems with first layer because I was getting the clicks to after only 6 weeks of owning it. Not had any more clicks since I adjusted the belts correctly

They were miss aligned causing undue stress on the belts and motors as it would. Hope this helps you

I have had that issue with filament debris in the nozzle. I also had a time when the K1C randomly turned off the extruder heater while printing. Needless to say I came back to a constant clicking with the extruder trying to feed and not being able to.

When that happened, I had flattened filament in the extruder gears, so it couldn’t go forward or backwards. I had to disassemble the whole thing to remove the damaged filament.

Hello @David_Mason …! :wave:

Welcome to the Creality Forum…! Creality

So this is happening on all three new printers…? I’m wondering if it could be caused by a slicer setting… I once set the retraction wrong. It’s supposed to be .4 but accidentally put it at 4 so that caused a problem.
