Heating and Homing failure after rollback from Release 5 to official Creality firmware #223

Closed ryantang30 closed 3 years ago

ryantang30 commented 3 years ago

Description

After upgrading firmware to Release 5 successfully (was able to home, level bed and print normally), rolling back to any Creality firmware version or Release 3 (As advised in Release 5 release notes) results in nozzle and bed unable to heat up at all, and z-axis homing to always fail (nozzle keeps going down even after opto sensor is blocked and blue light shows up on daughterboard on nozzle assembly. This results in the nozzle crashing into the bed.

When I re-flash both screen and motherboard firmware back to Release 5, all functions become normal again.

Steps to Reproduce

  1. Flash Release 5 firmware to both motherboard and screen
  2. Flash any official Creality or Release 3 screen and motherboard firmware
  3. Attempt to auto-home nozzle and heat up nozzle/bed

Expected behavior:

Auto-home completes normally and nozzle/bed heats up normally

Actual behavior:

Nozzle and bed unable to heat up at all, and z-axis homing to always fail (nozzle keeps going down even after opto sensor is blocked and blue light shows up on daughterboard on nozzle assembly. This results in the nozzle crashing into the bed.

Logging:

Did not do any logging as I am not sure how and if its relevant. If required, do let me know.

Official Creality V1.0.3.6 is for v4.5.2 Mainboard. Have you tried Creality's download page? https://www.creality.com/download The 28 Jan, 2021 releases have a [ 4.5.3mainboard (C & E version)（common with CR-ERA V1.1.0.3mainboard - CR-6SE - V1.0.4.1(1).bin ] that might work with a v4.5.3 Mainboard. There is also a CR-6SE - V2.0.1.3 - HW - V4.5.3(0127).bin.

I haven't tested any of those. Creality had a version that was supposed to be for v4.5.3 but was actually compiled for v4.5.2, so use at your own risk.

@ryantang30 Creality incorrectly published v4.5.2 board firmware as v4.5.3 firmware - this has been going for a few months now and apparently they still haven't addressed that. That's the reason the heating doesn't work and homing fails.

Either way, not something that I can fix.
