Not bad for Python in general ;-) No, seriously, great job. Did you make roll own electronics? Or is this with some included interface? This is using the default interface electronics. Ithaca is pretty well documented - I'm making good progress. Working on my slicer software now. The more interesti...

Not bad for an hours work reading the spec and writing Python.

Picture of the carriage motion of the Ithaca POSJet 1500: IMG_0858.JPG Although only one ink cartridge is installed, both cartridges are fully wired up. The drive is classic stepper motor, with a optical endstop. For a mini-powder printer, this looks ideal. For a large format printer, the mechanical...

POSJet 1500 ordered, and on its way. I'll post a tear-down of the print engine once I get it. Should be interesting. Also, I've ordered a EPSON CMY label printer (OEM version of the TM-C610), which will be a more difficult hack to get working, but it's piezo ink tank-based print engine may be more u...

Thanks for the link to the 'sandbox' printer.

I have a powder handling subsystem from an old laser printer (used to move toner to a waste bin) that I could use for a similar design - very inspiring!

And speaking of printheads: http://www8.hp.com/us/en/ads/officejet-pro-printers/officejet-x-series.html HP's PageWide inkjets are tank-based, durable heaters, and prints the whole page in one pass. _That_ is the tech they are putting in their 3D printers. Which means they have a resin formulation th...

UV resin on powder - that's the HP 3D printing technology.

Very strong, supposedly.

The 'ZP-150' is kind of a joke.

Plaster of Paris and two nesting cardboard tubes as a form would be sufficient.

Cruising through eBay, I noticed that the "Ithaca POSJet 1500" seems to be available as a 2-pen device (HP C6602A, just like the InkShield), USB port, and with an 'All Points Addressable' graphics mode - for about $50-$100 shipped. Programming manual available at: http://www.transact-tech....

I would suggest tying all the 'unused' addresses and primitives to their off state (Vcc, right?)

They could be leaking to ground if untied.
