Re: Ricoh printheads

Sorry it's been a while, I am still working on this. I have managed to get basic printing working enough to print some test patterns. I am currently working on the FPGA system for taking images and then sending them to the printhead etc. This project was significantly more complicated than I initia...

Re: Buying an Oasis 3DP or Plan B ??

What is your budget? I'm developing an inkjet printing system that can be controlled with Klipper, and while I can't make a complete machine for you, I'd like to get a feel for your needs and explore potential customers ;)

Re: Where do I start?

I have completed the inkjet test of the xaar1003 nozzle driver and am now working on the development of the cycle inkjet system. My idea is to add a pump at the input and output, and then the output is greater than the input, so that negative pressure can be generated. Some pressure sensors and pid ...

Re: Ricoh printheads

That an awesome project. Thanks for sharing. I have some questions regarding your project. 1. What kind of controller are you trying to using in your printer for motion? How do you plan to sync the motion with jetting? 2. What kind of ink are you planing to use? At first I planned to use a grating ...

Re: Ricoh printheads

I also have the intention of making an ink circulation system, mainly to facilitate the heating of the ink material. At present, I am developing the nozzle of Xaar1002/1003 series, and I have completed most of the hardware design work, and I am still debugging the firmware code. Unfortunately, I do ...

Re: Hacking xaar 1002/1003

I originally published the Xaar 128 PCBs and code here. It would be great if the OP could send me the data sheet and documentation. Maybe I can help a little. It would be even better if I could get my hands on one of those 1003 heads for a lot less tha 4k$. Any ideas? Thanks, Wonko. Given that this...

I figured this thing out, the next two lines of components are used for power supply :geek:
