Awesome! I don't know how good/exact they measure, but maybe it can already lead us in the right direction. ..also pinging @sjorge as I think you're interested in that as well, just in case you miss this discussion ;) |

Curios as to what your findings will be. |

Could you two perhaps upload your slicer settings? Just to be sure we're all testing with (roughly) the same setup |

I'm still trying to find the 'perfect' settings as I still encounter problems like gaps between walls, holes between infill&walls etc, even tho I already raised the % on the different line widths, turned on Arachne etc, but here you go:

Generic 3950 is very accurate, the atc sensor type is usually off by a few degrees. Haven't tried changing anything for the heated bed yet, it's consistently off by 1-5c, indicating a lower temperature than what it actually is. Setting the bed at 55c would result in it actually being around 56-57c, and setting it at 65c it's closer to 68-69c |

Results so far:
With magnetic bed, all given 4-5 minutes to warm up after reaching their target temperature |

There's a couple of things I want to retest for the nozzle, had some inconsistent results in the tests that I did |

Ah, so it's one of these IR thermometers? I do have one of those as well and used it for checking the bedtemp, but somehow it doesn't seem to get the right spot at the nozzle, so I can't check the temps with it there.. :( |

I just place the end of the thermometer over the nozzle (being careful not to damage it), and been getting fairly decent results that way. At this point it might just be worth it to take apart the extruder and check the sensor if possible. I've ordered a contact probe as well though |

I have one of those cheap IR-laserbeam-ones which produce a cone when measuring, somehow it didn't work yet with small and close-up objects. But I'll try again as well.. |

I've upgraded to a V6 block + bi-metal heatbreak + NTC 100k thermistor, given I print PETG most. I did not swapped the heater cartridge though. Gonna see how that goes. |

Thought about changing to a V6 as well, but because I have so many spare parts, I just changed the heater block to a V5 plated copper one. So what's your impression? Is it an improvement somehow? If so, maybe open a "show&tell" discussion in the repo of the actual pages, so that I can link to that one. Pics would be highly appreciated, I maybe even could add it to the pages in the "Mods" section if that's ok for you, I think other users might be interested in that as well. Or just send me an email in case you wanna contribute that?! Thx ;) |

Still messing around with it, it seems to work, but I'm having issues with the ali express GDSTIME fan so going to switch back to the anycubic one, also will need a new longer fanguide as both the stock one and one I was using from printables was blowing only on the top/mid of the new block. Sick at the moment, so I have not continue messing with it. |

Just read in a German 3d forum that someone also used a GDSTIME fan at his Anycubic Mega with Klipper and he said that it worked better with the default 100Hz - another user who used SUNON said, that that one worked better with the ~32kHz. Due to my other heatbreak I also had to adjust a model of the part cooling fan duct for allowing it to move it down further. It's the one I linked to from the pages, the one where the stock fan fits into and which sools from three sides. I also made the three sides pretty equal in length, adjusted the airflow in the inner part with adding an angle and so on. Works pretty well for me actually. If you want, I can send you the file, maybe that fits for you as well. If you're interested, just send me an email.. Get better! |

The ATC one is defined in the marlin firmware, that's why I used it in my klipper config. I may try to digging into the official marlin firmware more, to find out what may did anycubic do for their thermistor. |

I noticed some comments on the latest commit about the sensor type. I've got an ir thermometer arriving this Sunday so I'll do some measurements with various sensor types in my config and keep you guys posted
