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?
Technically you could throw in edit Klipper based board if you wanted to dive into setting up the firmware. It would not surprise me if there isn’t already a klipper or Merlin profile for it. I’m currently converting a tronxy x5sa 400 pro over to a maker base klipper board setup. And even that printer has a profile out in the GitHub that I can modify a bit.
Yeah the issue is AnyCubic seems to have dropped support for this board and any configs online are done by the community. But all of them are guessing the config because AnyCubic didn't release any code or examples. Very annoying.
Yea, any cubic makes great resin printers but their fdm printers seem to not get the love and attention they deserve. (And that’s coming from someone who bought a tronxy ;) )
From AliExpress I think I roughly spent about 100$ on a makerbase all in one board with a built in pi, a touchscreen for it, and an input shaper board- those 3 parts should let you upgrade the printer and allow for much faster print speed
