It's out of stock for a long time...

You have to change the screen firmware as well.

Hi, I only flashed it (also the screen firmware), but didn't have the time to print anything. I've played with the menus, seems ok. The only thing not clear is the version number (1.5). Can you please ask the devs to clarify: is it 2.0 or not? (If 2.0 which branch did they use)?

LOL, sorry

Yes, it's quite simple. Connect your printer to your PC with a USB cable. Ensure you have CH340 driver installed. You need to setup your printer within Cura (there's an Alfawise U30 profile, but you can use Ender3 as well). Then go to Settings/Printer/Manage Printers/, there highlight your printer and you'll see the Update Firmware button. Choose custom firmware, browse the .hex file and you're done. The update will took around 30 secs or so.

I flashed mine with Cura, took 30 seconds. Don't understand why the took the harder way

I've uploaded, minor issue: the about menu still shows it as Marlin 1.1.9

+1 on the repo update

Either replace your thermistor or before do that disassemble your hotend and remove then reinsert the thermistor. Mine was overtightened with the screw at the factory. Loosened and no problems since that. (To be fair I also replaced the heater wires as well - just to make sure). Both are cheap replacements parts, I think it shouldn't cost more than 4 euros at all.

Where is the 4th fan? Inside PSU?

This github is nothing more than a fork of Marlin with 3 changes regarding some funding URL. He doesn't change anything in the config.

Hello there, had the same problem, the solution was to replace the heater cartridge (I purchased it from creality, but any 24V ones will do it). One minor thing: LK4's heater cartridge is around 110 cm long, but you can only purchase 100cm long cables. Anyway, that also fits perfectly so no problem. My advice: when you purchase, buy a replacement thermistor cable as well. It's cheap and you'll have a replacement.

Hi, regarding 0.3.2 changelog, here's a copypaste from Longer 3D official Facebook. This is a temporary firmware version, which only enlarges the range of temperature detection. This is only for some users under certain conditions of use (for example, the ambient temperature is very low, the fan has been replaced by the user, etc.), the temperature cannot be stabilized at the target value for a short time, resulting in an abnormal temperature alarm on the display of the machine. This firmware is only generated for some users to solve abnormal problems, so if your machine does not have any temperature alarm problem, the 0.3.2 firmware is temporarily useless to you. When we release some big changes, we will release the firmware source code and change log
