Even teletypes have firmware.

It's 10 times the number of instances that lemmy.ml blocks, if that helps.

Someone who claims to be a socialist, but who has a pathological obsession with identity politics and dividing the working class, and gives little regard to class consciousness or worker solidarity. Usually has an extreme hatred of patriotism despite patriotic socialism being the official ideology of the Soviet Union. Often defends lumpen behaviour to a bizarre extent.

To add, if it's using the Melzi board that some used, then you should be able to load g-code onto it using the micro SD card slot. It will depend on the firmware if it can recognise modern gcode though. You may be able to compile a modern version of marlin for it too.

It's very flat, it works well with PLA, and it's what my ultimaker 2 came with.

I went with a laser and small dye sub printer. If you only need occasional 6x4 photos it's probably the best option.

So many OSHA violations.

Still less embarrassing than recommending GIMP.
