Re: Hacking the Xaar 128 printhead
Hi Ivan, That is quite an impressive machine. I don't have a diagram to share (just the pin configuration in my code on github), but I have a suggestion: screenshot.png This is a trace from a logic analyzer for one successful "jetting" of my xaar 128, using the code I posted on github. The...

Re: Hacking the Xaar 128 printhead
Also, quick note on FFC connectors: I suggest doing something to stabilize the cable right where it meets the connector. After some use, my FFC cable started to bend and pinch near the connector. This part isn't really designed to flex. Eventually, some of the connections over-flexed and started to ...

Re: Hacking the Xaar 128 printhead
I'm stalled for a couple of weeks waiting for material (shipping from China). evomotors, This code works on Arduino Uno or Mega, which both have a USB port and TX/RX pins that can be used for serial I/O. If your Arduino is connected via USB, it should expose a COMM port that you can connect to with ...

Re: Hacking the Xaar 128 printhead
If someone is using one of these 16pin IDC-style connectors, it'd be great if they could document it on the wiki . I picked up a different one than you have pictured and I *think* it was for the Xaar 126 -- When I started mapping the pins, I found that some of the Test pins from the printhead were e...

Re: Hacking the Xaar 128 printhead
Okay. I'm sharing some minimal code to get started: https://github.com/gkyle/xaar128 Usual caveats. I'm not handling errors, but this code at least counts failed fires, which happen (quite a bit when your nozzles clog). I'm using no external components that aren't called out on the wiki, so you can ...

Re: Hacking the Xaar 128 printhead
Hey all, I saw this thread a few weeks back and decided to try for myself. I have a working configuration, aside from daily nozzle clogs, and have started posting my notes on the RepRap Wiki here: http://reprap.org/wiki/Getting_Started_with_Xaar_128.
