Current Status: Mostly functional

Specifications:

• Build Volume: 200x200x200mm
• Materials: PLA, PETG (1.75mm)

Current workhorse printer at the space. It's a Micro Center (PowerSpec) rebranded Wanhao i3.

Now part of the Octoprint farm, on port 8082. You should be able to submit jobs to it from Cura on most of the computers in the space.

Filament-wise, we've used PLA approximately 99% of the time on this one. We have printed a little PETG, but never ABS or more exotic filaments. While it has a direct drive, it would require some modification to allow flexible filaments.

Modifications:

• The hotend was upgraded to a Micro-Swiss all-metal hotend. The nozzle is “plated brass”, so extended amounts of glow in the dark filament may not be the best idea until we get an all-stainless or something else.
• The extruder cooling fan has been replaced several times (note: it's a 24 V fan)
• Parts cooling fan was replaced with a blower-style fan and a “wraparound” nozzle.
• Now using a glass bed for a print surface

Slicer configuration:

• For the most part, Cura's defaults are fine- set the size to 200x200x200 (or use their canned Prusa i3 profile). If using a generic profile in Cura, remember to set filament diameter to 1.75mm
• Nozzle diameter: 0.4 mm (this is actually the default, but noting it for now in case it changes in the future)
• Enable Retraction
• (IMPORTANT) Retraction distance: .6mm (this is vital with the all-metal hotend, the default will result in problems)
• Bed Temperature: 60
