Picked up an AnyCubic 4Max Pro (self.3dprinting)

Hey everyone,

I just grabbed an AnyCubic 4Max Pro for insanely cheap. I had to swap out the hot end, it was bent. It seems the last owner had the Z limit switch incorrectly set so it was crashing.

So far it's printing fairly well. I need to do all the calibration and such, but for 'out of the box' it seems to be alright.

I've been reading up on the hardware itself and it seems to be fairly crippled due to the board AnyCubic used. An 8 bit board based on the Arduino Mega. I've see lots of pre-conpiled firmware for Marlin 2.0.x but they're usually filled with even more bugs than they solved. The board is called TriGorilla? Honestly I'm use to BTT and Crealitys boards.

Has anyone done a board swap on this? I saw the LCD is a hack job by AnyCubic since Marlin, maybe at the time?, Didn't support DWIN touch screens. I'd like to keep the stepper drivers, so maybe a board that has removable?

Thanks Henry

Generally running Marlin 2 on 8 bit doesn't work out so well. This is why Prusa MK4 is such an expensive upgrade and why they haven't been modded much by the community; because of backwards compatibility from their first i3-MK3s+ and the original 8bit boards that ran Legacy Marlin.

I don't know the hardware involved with this AC M4P, but am into hobby electronics pretty deep, and maybe know enough to get myself into trouble. You can run most printers on klipper firmware if you have a computer running Linux. The Linux computer can be anything from an old PC or laptop to a raspberry pi. I think this is much easier than messing with Marlin 2.

If I'm looking for stuff like firmware, I usually just search github directly. If I can round up half a dozen projects where people have posted their firmware and configuration, I can usually piece something together that works, or at least weed out the bad ones to get a better baseline.

I haven't had much issue with running Marlin 2.x on Crealitys 8 bits. Of course I stripped out stupid stuff and enabled things like arc and bltouch. It runs totally fine. It's the lack of storage that was the issue.

With that said storage isn't so much of an issue with the Mega(atmega2560), the real issue lays with AnyCubic and the mishmash they called TriGorilla.

Thanks!

Cheers Henry
