PTFE TUBE

Please tell me! How long should the PTFE tube be on the Anycubic kobra 2 plus 3d printer

had such a problem. It is enough to simply lower the sensor down. It reacts to metal and if it is raised too high, it will push until it sees the bed.

The brand of the Anycubic kibra 2 plus 3d printer, nozzle temperature 240, table temperature 70. I don't know what else I can write, because I'm still quite new to this 3d printing business

Thanks you for help! Problem solved changed PTFE tube. Thanks you again!

Problem with extruder

Hello. I have an Anycubic Kobra 2 Pro printer. There is a problem with underextrusion, most likely the problem is that the extruder is not calibrated. You need to find out the number of steps. How to do it?

Problem with nozzle

After some time, seals appear on the nozzle. What should I do about it?
