Extruder heating way past desired temp

by TheGuyWithARock

Been having some problems with my extruder for my cr10 so I ordered this replacement from creality: https://www.amazon.com/dp/B07CKQRT89/ref=cm_sw_r_cp_apa_VF0CBb456WPHZ

Now I installed it and securely soldered the connections and now when I preheat it the temp rises past the desired 195 to 230(or probably past as it starts smoking and emits a foul odor) so I turn off as to not damage the parts. Im at a loss, is this not the right part? Could it be a faulty connection? It displayed the temp rising so I I can only assume itd actually shooting past the 195 mark.

Any advice would be greatly appreciated!

Thank you!

HELP!!

by OmniProps

I was trying to make sure that my x axis was level. I printed off 2 brackets so I could level the x axis and I noticed it was off by a good deal. I was checking the rollers and what i show in the video is what I found. The roller is very loose I tried tightening it but nothing worked any suggestions? Thanks

Z-Axis missing 0.5mm

by Ins0mn1a

When Z-axis is at home (+/- 0), and I move it 1mm (printer menu or OctoPrint), it only moves 0.5mm. From then on, it always moves 1mm, i.e. on 10 my caliper shows 9,5mm, on 20 it´s 19,5 and so on.
First Idea was to ensure Z-axis does move equally on both sides. After a bit fine tuning all fine, no matter if I f.e. move to 30 then down to 20 -> 19,5 and move to 10 then move to 20 -> 19,5, values taken right side of x axis .
Also checked the limit switch and coupling, all fine.
Then I installed Marlin 1.1.6, and had a look on jerk and acceleration speed. Even with half the values, the problem persists.
To check if it is a software problem,I moved the z-axis to ~50mm, then let him move to auto home. When at ~30mm, i pressed the limit switch two times. Moving from there +10mm up, he moved exactly 10mm.
Any ideas?

Clogged nozzle? HELP

by OmniProps

I have been printing things just fine but a couple of mornings ago I woke up my a print had failed. It had appeared to have some kind of under extrusion or something along those lines. Today I did a test piece (the top piece in the pictures) and it turned out terrible. I assumed it was some kind of clog so I changed my nozzle and tried again (bottom piece in the pictures) now I don't know what to do. Any suggestions? thank you

Hot-end insulation

by Rapsey

I recently bought a set of silicone hot-end socks. When I wanted to install one I noticed the hot-end is already wrapped in insulation as shown in the picture. The silicone sock doesn't fit over it, I would need to remove the insulation for it to fit.

Are silicone socks intended as replacement for the insulation? Are there benefits or downsides to using them?
