Firmware update failed, help unable to recover
I want a fast printing 3D printer, user friendly and faster than my other printers, with no need to optimize or change hardware and compile own firmware as usual in Marlin. So I bought a qidi xmax3. After downloading the actual slicer from qidi I got a suggestion to update Firmware to actual 4.13.5. Followed the steps in qidi.wiki and: printer is down, klippy not connected, no more function. Contacting support, some suggestions were given from there, one E Mail per day! and they send me a new emmc with a software image to boot that should solve the problem. But it contains the same old firmware, so the problem start again. They ordered me, to open the printer and manipulate the electronic, (well, I'm a rocket scientist) boot again and: No change... Now, 14 days later, they send me another file to boot the printer and reset it, but: NO CHANGE Finally the asked me today if I COULD MAKE A VIDEO of the steps I did to resolve the problem. Ha, I'm NOT George Lucas ! Conclusion: quidi software is totally bugged and they are not able to resolve problems. The printer might be OK, but electronics and this very special version of klipper is not user friendly.
