Re: Hacking cartridge HP 84/85

I made a connector that holds pogo pins. I will also make an ink supply and a suction cup, and then I can test whether I can send lines to it.

Re: Hacking cartridge HP 84/85

I do finally have the time, and now that you have shared this, I finally bought an HP84 myself. I do hope I can find a few days around Christmas to mess with this. First thing I will make is a connector so I can wire this up.

Re: Hacking cartridge HP 84/85

Thank you for sharing this. I will see if I can replicate this over the next few weeks. You have made a nice summary. For sharing code, you can zip it and add it as an attachment. We might not be able to read it in the forum, but we can at least use it. Looking at the voltages, I have to assume that...

Re: Hacking the HP45

I have not been working as much as I wanted on the Oasis project. Now that the turret is done, it was planned that I was going to work on HP45 related work. However, responsibilities and other smaller projects took the majority of the time. I have done some work again. I have made a controller that ...

With that I can give pointers: https://ytec3d.com/the-z400-blog-part-8/#comment-52407 In the comments here, Ezrec has give some pointers, and he has a webpage http://www.evillabs.net/index.php/ZCorp_Z310%2B#Materials I have compiled a small list here: http://ytec3d.com/plan-b-printing-materials/ Las...

Re: New project powder 3D printer ZEUS

Powder composition would not change printer design (much). The bigger issue is that how well your printer prints REALLY depends on your powder and binder. There are a few people who have done work, and you can hope that it will work instantly, but most likely you will need to tweak the powder or bin...

Re: Hacking the HP45

I do not have time to change it. That does not mean it cannot be changed. If you want to mark a product, you will need to know where it is. Currently, my controller needs an encoder, but in principle, you could just tell it that it needs to print at say 50mm/s, and then tell it to start printing. Ho...

Re: New project powder 3D printer ZEUS

I can second this. Since plan B, my printer have gotten smaller volumes, not bigger. Especially if you do not have a working powder recipe you want to print with, you want small machines. I am literally designing a 20x50mm printer so I can test powders. Plan B is currently 80mm round and is big enou...

Re: Hacking the HP45

I cannot provide any real support other than giving you what I already have, but the current Oasis controller should be able to do most of it. You will need a way to convert text to print, and if you don't have an encoder, you will need virtual speed. The hardware is there though. I do warn though, ...

Re: New project powder 3D printer ZEUS

Your design looks very solid. Do you have the manufacturing capabilities right there to make the metal parts? The basics of you hopper looks great. Do try to make something that is easy to clean. While a piston should not leak much, it will leak a little, and printers can gather enormous amounts of ...
