Wow that looks amazing.
I got into 3d printing beacuse I had an interest in it for a few years. I had a friend that was making a pocket tool holder and i thought that was an amazing idea. Sine then it’s mostly been a learn how it works, make silly/useful things for my friends and family, but mostly something to tinker with.
My original goal with my first printer was to max out the boards stock capabilities and i’m pretty much there after about a year. Theres still some room to try different things, but im now upgrading the board to better set up for ABL. Ive learned soo much about hardware and software, and there is still much more to learn.
For reference I started with a AdimLab Gantry-S which is sort of a clone ender 3 useing a MKS Robin Lite V1.1 board. The community behind the printer is fantastic. Ive update the firmware several times and currently only have a minor bug i cant seem to fix (eeprom saves to sd card not the chip). I tried out TL Smoothers to meh success and have since removed them from my setup. Switched to a removable flexable steel sheet and also use glass. Ive installed a isolation dampener in my lead screw, I think it’s helped, but its negligible. I tried the MKS wifi chip to no success, though a rasberry pi is a better took and investment anyway. Ive used the rasberry pi with the printer but havent dived into that world quite yet.
Im still considering linear rails or rods eventually. I’m thinking about going with dual extruders or dual z steppers, or both (just upgrading to a BTT SKR V1.4 Turbo) and my most ambitious goal is to try and impliment a filament diameter sensor with the possible goal of using it as a run-out sensor as well.
