My old printers are pretty... old, limited, not printing well anymore, or are in a zillion pieces. I've had intentions for years to build a new one; maybe now I should get around to it. Not my first rodeo; my original 2012 Replicator has been modified into unrecognizability, but it's the one in pieces and it would still be limited in size. Requirements: Core-XY mechanism 300 mm^3 minimum, more z is better AC heating bed dual z-axis screw lift; belt or dual-motor syncronized dual cantilevered bed 3-screw leveling enclosable direct-drive extruder 24V need to keep additional component purchases to <$500 220/221, whatever it takes.* What I have: plenty of decent NEMA 17's power supplies, fans SSR for the heat bed handfull of odd bearings bunch of M3, M4, and M5 hardware bunch of odd extrusion; unfortunately, none of it the common 2020 (all 3030, 2525, 1010) excellent 6mm aluminum build plate GT2 belt the printer I have working will be adequate for printing new printer parts in ABS. What I need to decide/acquire: controller (I'm assuming for the moment, Duet2wifi) extruder/hotend - open to suggestions (not familiar with current crop) [as an aside, I had my Replicator set up for hotend water cooling, for hi-temp printing; worked well so that's something I'd be thinking about.] silicone AC heating pad rails and/or rods z-screws with anti-backlash nuts assorted bearings, idlers, pulleys. What I'm looking at: Hypercube, Hypercube Evolution (HEVO) - large, active users group, many builds and modifications. D-Bot/C-Bot Core-XY - huge, active users group, many builds and modifications FORKlift MK1 - small users group, some mods available, CAD files available; and with beautifully engineered printed parts. SecKit Core-XY - not an original build but a kit that checks most of the boxes; unfortunately while it's somewhat configurable, it would still duplicate much of the hardware I have. V-King Core-XY - while I've got some v-wheels around here, I think I'd rather stick with linear bearings or rails; interesting though, and a unique z-axis lift. Jubilee - don't know much about this but it appears to have a workable DIY toolchange system. Anything else I should be looking at? First thing I need to do is go dig up and inventory my extrusions. Thinking about trial printing some of the FORKlift parts (really like the adjustable motor mounts). Thoughts/suggestions? * That's a joke, for all you Mr. Mom's out there.
