Re: Hacking the Xaar 128 printhead

Hello Everyone, I've made a board with LED driver, 3 stepper Drivers (TMC2130), on board voltage regulator 28-36V for the Xaar as well as other drive circuitry required for the Xaar Printhead that uses Teensy 4.0 as the brains. There are SPI lines broken out for for further expansion as well as 4 d...

Re: Hacking the Xaar 128 printhead

I am interested in your board. Do you have any of them left? What would shipping cost to USA? Yes I still have them. Well I make them on order so I will always have them :). Very little because I live in USA as well. Though the price includes shipping so no one has to worry about the shipping costs

Re: Hacking the Xaar 128 printhead

What is new in this board that haven’t been discussed before in this forum? How would one use this board? I don't know if there is anything new in the board per se. It's an overall control board that has everything I needed to make a printer and hopefully it have what other people need too. Using t...

Re: Hacking the Xaar 128 printhead

I found UV Ink from Kao Collins. I'm in USA though. I don't know how you can find it if you are not in US.

Re: Hacking the Xaar 128 printhead

Hi, This is my setup. You can see the damper above the head, the capping station I built (with a silicone band gasket and peristaltic pump), the reservoir and of course a print sample. The sample print is 8 times overprint microweaved. My head has a full blocked nozzle and many nozzles are deflecti...

Re: Hacking the Xaar 128 printhead

Okay sounds good. I’ve read your posts and as far as I understand you are using a vacuum pump and seal the head against it to vacuum the ink. I was thinking about using something similar.

Re: Hacking the Xaar 128 printhead

Thank you for your response... I guess I fried my Xaar head need to get a new one :roll: :roll: ... :lol: What kind of booster are you using? I'm really hesitant using a cheap boost converter off of amazon/ebay because of transient voltage peaks that one might encounter during powerup.

Re: Hacking the Xaar 128 printhead

Hello everyone... I'm having some trouble with my Xaar 128.. The printer was working fine with Kyle's code (https://github.com/gkyle/xaar128/blob/master/xaar128.h) with a simple addition of stepper motor header file and class but for some reason it stopped working... I'm using a 36V power supply wit...

Re: Hacking the Xaar 128 printhead

Hi, Indeed, working with high voltages and digital signals can be troublesome. For a prototype setup like ours, I would use relays. What ink do you use? How do you store the printhead so it won't clog? Yeah as of now I use relays but I will try mosfets too. I just use an alcohol based ink and the p...
