Hi my name is Darek To make it easier for me, I write by google translator. I have a K8200 and from week I have a problem with the printout. The problem is that the prints suddenly deteriorated. Re-install the software and restore the factory settings doesn’t help. Print shown below is from the PLA, the temperature 190, the distance of the nozzle from the table 0.25. I have the settings for Slic3er from Velleman site. I covered with grease all the guides, cleaned the nozzle and checked the voltage on the drivers (about 415-425mV). Previously, it was all OK and I was able to print fine rack. Currently it is not possible. Where could be the problem?
Hi. I have the temperature set at 190. With pyrometer the temperature of the table agrees, but the nozzle has about 150 (but I’m not sure if the measurement is valid). I wonder if the thermistor with increasing tempearatury does not increase the error.
In your video it looks like the plastic is not sticking to the bed.
Clean your bed with alcohol
It also looks like your Z axis is out of calibration.
As a test when the print starts try turning the Z axis down (closer to the bed) by hand.
Just turn it a little at a time until you see an improvement.
