Emulating Ink Cartridges

February 2, 2011 by 15 Comments

[Smartie_on_computer] wanted to do some experimenting with an epson printer.  After getting a somewhat disassembled one, the first step was to simply get it running. Unfortunately, one of the ink cartridges was missing and these printers refuse to do pretty much anything without all the cartridges installed.  Rather than go purchase a costly cartridge that they didn’t intend to actually use, [Smartie_on_computer], chose to emulate the cartridge using a microcontroller. After some searching for the protocol used on the cartridge, the info ended up being in the patent. [Smartie_on_computer] now has a functional printer that is destined to be a 3d printer in the near future. You can see a video breakdown after the break.

DTG: Improved Printing On T-shirts

November 16, 2010 by 21 Comments

[Jeff German] improved upon his DIY direct to garment printer an ended up with a machine he thinks is equivalent to anything you can buy commercially. We last looked in on this project in June but much has been done since then. Most notably, there are build instructions available (requires login). [Jeff’s] printer is based around an Epson R1900 plus the base that holds and feed a garment. Take a look after the break to see it printing full color designs in high resolution. From the YouTube description it sounds like he wants to go into production with this. Kudos to him for also sharing the build techniques.

Servicing An Epson Projector

October 28, 2010 by 32 Comments

[Socket7] got his hands on a projector that had some color calibration problems. Of course the servicing manual says that there are no technician serviceable parts inside, but he cracked it open and fixed it anyway. This is an Epson PowerLite 5500c which was showing blue and yellow bands around the outside of the projected image. He could hear something rattling around inside which happened to be the lenses. It turns out there are foam pads that hold them in place that had shriveled over time. After a bit of careful work he replaced them and now has a working projector.

We’d love to have a projector of our own; there’s a lot of cool stuff you can do with them. Fixing a broken one is a great way to get one cheap, [Socket7’s] was free!

1 Watt Laser Engraver

September 13, 2010 by 20 Comments

This laser engraver was built using printer parts, a CD-ROM carriage, and some homebrew electronic boards. The laser diode is a 1-Watt model similar to what we saw used as a weak laser cutter back in August. When the width of the material changes the focus of the laser is affected so the diode was mounted on a CD-ROM carriage (in the Z axis) for easy adjustment. The X and Y axes are made using parts from Epson Stylus 800 and Epson Stylus Color II printers. After the break we’ve embedded a video of the machine engraving some wood using EMC2 software on an Ubuntu box. It also boasts the ability to cut paper and some plastic but it can’t compare in power to a CO2-based unit.

DTG Using A Stock Printer

June 27, 2010 by 27 Comments

Here’s a Direct-to-Garment device that uses a stock printer. [Jeff German] used an Epson R1900 with the stock firmware to get the results seen in the video. His hardware modifications involve adding two buttons to the printer’s circuit board. For DTG beginners this certainly lowers some of the obstacles to getting started. [Jeff] is working on detailed instructions but for now take a look at our own How-to for building a DTG printer.

(mini)How-To: Refill Your DTG Inks

June 9, 2010 by 18 Comments

The number one and number two things asked after presentation of our DIYDTG were…
“How does it hold up in the wash?”
and…
“How did you change out the inks?”
While we’ve explained the first several times (regular ink washes out, DTG ink gets a little lighter but survives) we can hopefully answer the second with a tutorial.

Direct To Garment Printing

Reader [deren lik] pointed out the world of direct to garment printing to us. You can purchase commercial machines that will print directly onto a t-shirt using inkjet technology. Unfortunately, these machines cost ~$10K, so hackers have decided to fill in the gaps. DIYDTG hosts plans for how to build your own DTG printer. Their standard instructions are based around the Epson C88 printer. A custom carrier is constructed and then the printer components are bolted on top. Commercial DTG printers are also based on Epson parts and you can easily purchase the garment inks even if you didn’t pay a premium for your printer.
