Re: HP45_Standalone_3.0 Controller Software ( C# )

The data you need to send before printing varies much on what you want to do. On Oasis I use the following commands: "BCL" : Buffer clear. Clears all lines in the buffer. This is to clear anything left in the buffer "SDP" : Set DPI (with the value for DPI). Needs to be proper div...

Re: HP45_Standalone_3.0 Controller Software ( C# )

Attached is the version of Oasis SA, or Oasis standalone. This is a test version I used to test the DMA printhead. Integration into any project is strongly discouraged. The current Oasis controller is a spaghetti mess. You can load in an image, press convert SA, and it will prepare the file for stan...

Re: HP45_Standalone_3.0 Controller Software ( C# )

The full explanation will take a little time. I will upload the code tomorrow, and start answering the questions you asked here and in private over the following days. I have to dig a bit how it works myself as well. Some layers are abstracted away for me.

Re: Site changes

I changed the registering spambot countermeasure (again) to a Q&A. I dislike using it, but I hope to keep spam to a minimum this way. The oldest way blocked non-bots, and the new old way is letting through 80 accounts a day (This forum does NOT have 2200 members). I hope the question is simple e...

Re: Grain micro powder printer

It is an ordinary HP45 head, but I can easily fill it with any type of ink I want. I preformed the tests with yellow ink.

Re: Hacking the HP45

If you swap HEN and TSR (cut the traces and add new wired) it should work.

Grain micro powder printer

It has been a while since I posted new stuff. I have been (and still am) busy with other projects. One of them is finally finished however. This was Grain, the micro powder printer.

Re: Hacking the HP45

Can you tell me exactly where and roughly when you downloaded the files for that board? I recognize that layout, it is the prototype V3.00 controller that I used to have. The pinout was wrong and the layout was fixed, but I simply resoldered 2 wires. The fact that people still have access to that wr...

Re: Hacking the HP45

@Priyashree2

You will need to add a 10k pulldown to every address. Also before you print you should always wipe the head. Even if you do not use them, floating addresses cause issues. I cannot find any issues with the code you are using.

Re: Hacking the HP45

I will try to run through all the issues in order. For more information on the printhead in general, go here: http://ytec3d.com/hp45-inkjet-printhead/ The values for the 10X and the TSR are what the controller measures on the 10X resistor and the TSR resistor. Both are supposed to be in the neighbor...
