    I picked up a: SainSmart x Creality Ender-3 PRO 3D Printer from woot over black Friday. Figured the entry price point was low enough for me to tinker with, and not something I would be angry at if I left on the curb. ($155)

    Assembled it over Christmas, and have been dickering with it ever since.

    Upgrades to it:
    - Creality 3d upgrade kit of new springs, better tube couplers, metal extruder, and capricorn tubing. ($20)
    - BIGTREETECH SKR Mini E3 V1.2 (new main board) ($35)

    All the upgrades have gone in.. the mainboard has better firmware support and silent steppers so a plus.

    The springs were super to keeping the manual bed leveling less of an issue, couplers to keep the tube in, metal extruder because the plastic one will wear out with filament rubbing on it, and tubing for heat/retraction issues.

    I also picked up some digital calipers and ferrules crimper but the latter was overkill as the pro's power supply and mainboard were pretty rock solid.

    I use Cura for my slicer. Never thought how much time it sucks to print. .that may be the death of my love for this project.

    My boss picked up a Sovol3d on his friend's recommendations. It has a lot of nice upgrades for an Ender3 over mine, and wouldn't be a bad entry model.

    After a lot of futzing, swearing, and drinks I think I have this thing tuned in for PLA. The cube and level verifier helped quite a bit.

    Oh geeze, and yes.. CALIBRATE THOSE ESTEPS! That seemed to be the last blocker to get this really humming.

    Things I've printed:


    The makerbot fidget gear was especially a great moment. After failure and failure and more failure I finally have things tuned enough withing tolerance to print functional gears - in their housing! Super neat.

    I am off to inspect 'OpenCad' to see what I can come up with on my own.

    I also grabbed this deal on Woot. I have not upgraded it at all and I'm really pleased with the performance stock. (Compared to my Monoprice MP10, which sucks ass)

    I'm very interested in the new mainboard, though.

    The mainboard was this one.

    It took the mechanical whine right out and all I hear now are the fans running. Allegedly this has thermal runaway enabled, and integration for bltouches and other things. It looks to move much much smoother.

    The swap over wasn't bad.. just tape and label your wire groups and it should be fine.

    The whole 'settings save between instances' is going to throw me off. While I should have used a raft, I had a 'brim' set on this guy when it printed. Been a bit of a pain in the ass to peel off the layers, but I'll be damned how nice in-place-chain-links sound right off the printer.

    New game plan, find a cheap and not 4+ program pipeline to getting topo maps to STL files.

    Not bad for a first pass at some topographical fun. The resolution is super huge so I may go about finding my own pipeline plus a little Blender. To quote Jill Sobule "I think I can do better".

    i have been eye-balling the ender as well. came close to pulling the trigger a few times. i would mostly use it to print stuff for my mini-quads and rc planes/wings. probably other things as well

    have you tried any printing with TPU yet?

    no one around me has a printer, so it'll be a fun adventure i think.

    Haven't had a need for tpu, but a cursory Google search seems it is doable with an enser3 after a few tweaks and slower speeds.
