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...

Re: Hacking the Xaar 128 printhead

Hey everyone, I have gotten the printhead to work and can print what ever pattern I want but I have another question before I fry anything. I have seen all of you use relays to control the 35Vs and I was wondering if I can use Mosfets rather than relays. The documentation states in the page 35 that ...

Re: Hacking the HP45

Hey Restani, if you have a working schematic to drive the XAAR 128 can you please share it? I would be really happy! Thanks and have a nice day everyone. There is a Xaar thread in this forum: http://ytec3d.com/forum/viewtopic.php?f=8&t=47&p=1709#p1709 Xaar printheads have all the electronics built-...

Re: Hacking the HP45

Hi Dragonator! Hi everyone! I thought about putting the version 1.01 that it showed in the forum. My knowledge in electronics and programming is quite reasonable. I made some impressions using the C6602 but I did not take the project forward because I thought of something more interesting. I'm also...
