Same Problem here. You got that fixed somehow?

My Nozzle keeps running into the heatbed like a jackhammer and my heatbed and/or nozzle won't heat up anymore.

MB 4.5.3

Tried to upgrade to 2.0.1.3

Something went really wrong here.

Any suggestions?

Edit:

I installed this firmware:

https://github.com/CR6Community/Marlin/releases/tag/v2.0.7.3-cr6-community-release-5-beta?fbclid=IwAR3gDDFOC8ywo4sSQBcPSNj3paMAlKRz-HXJxnt7th3aGAmu4yxrAa1F4Co)#faq

now it seems to be working properly again. 

Bed leveling did work, printing the first object after the update now.

hey all

i updated the firmware to 2.0.1.3 from this site with the mainboard 4.5.3 and the heating was also not working.i flashed the firmware twice to double check everything is okay. after the second flash i was confused because the printer was new at that moment. i took the firmware from this site :

https://www.creality.com/download

--> CR-Series --> CR-6 SE 3D Printer and downloaded the latest mainboard and display firmware.

inside the zip package you will find 4.5.2 mainboard (C & E version) and 4.5.3 mainboard (C & E version) and 9-language firmware. i took the last one because i switched the printer to my language.

There you will find 2.0.1.3 for 4.5.2 HW and 4.5.3 HW. i took CR-6SE - V2.0.1.3 - HW - V4.5.3(0127).bin flashed and the same with the display. Now the printer works again and heating is working like before.

i hope you get your printer working again. for me i will stay at the stock FW so far i can.

Doh, I did not see your post before I posted mine, but I ran into exactly the same problem 🙂 and went for the same solution 😀

So, there really must be something wrong with the firmware...

@atbler Thank you so much for posting this. I have never been more frustrated. DIY shouldn't mean "DIY while trying to guess which firmware actually works, while simultaneously trying to make sure you are understanding the directions provided because the translation is so poor"

Thanks for posting this.  Had the same issue with no luck with official files from this site but those worked.

Head crash and heating.
