Thought I’d share my latest 3D printer incarnation (one of three) with the community here under a new combined post. It is basically a Ridigbot 2 converted to a 14" tall XL, with a few of my own mods. I love how easy it is to use. I can produce very high quality prints with it. Printed a one piece 14" tall Eiffel tower as a stress test with no support material.
Basic specs:
550 W 24V ATX power supply (it supplies all the voltages needed so the board does not have to)
5 driver main board with full board sized heat sink built in. Runs very cool.
Digital power level control over the steppers
Direct drive compact extruder (Dual extruder capable)
High efficiency part cooling fan duct. (My design)
10 x 10 x14 build volume.
Machined Aluminum bed (very flat, rigid, and light weight)
Pcb bed heater, with mounting tabs (I will not have the bed shorting problems that have recently been highlighted…)
LCD interface with USB port for computer free printing with active printing adjustments on the fly.
Very sturdy extruded aluminum frame in a molded base. Easy to access parts, upgrade, and tweak.
Using calibrated filament I can get prints from my printers, including this one, that are within .004" or 0.1 mm of design if not exactly on.
Once it is set up it is basically load and print.
