Re: Hacking the HP45

The bending of the connector is normal. The mounting holes are in the middle, and the springs on the side, so it is bound to happen. The springs usually compensate for this. One question. Do you have gold plated PCB or, tin plated?

Re: Hacking the HP45

If the head only shows a temperature when you push it really hard, the carrier you printed is wrong. Probably the pins do not protrude far enough out to properly contact the printhead. If the temperature shows, it is an indication that some pins are connected, but you only need 3-4 pins to connect c...

Re: Hacking the HP45

The VHEAD is an option for the future. Officially, the HP45 has a variable voltage on the primitives. Depending on the type of ink, state of the head, and environmental factors, the voltage required to fire a primitive is variable. On the C8855 controller there is a variable voltage available. The p...

Re: Hacking the HP45

Hello Nabi, If anyone would invest the time trying it, I think it would be possible. All the required parts seem to be there, and I think you can have enough control to integrate it into a diy printer. Do you have any special interest in full color heads? However I am not going to pursue products li...

Re: Hacking the HP45

The HP45 shares it's footprint with quite a few heads, but internally I can not guarantee that they are the same. All the CMY heads have 3 smaller rows of colored nozzles, not 2 large rows like with the HP45.

Short answer, I can only guarantee that the HP45 is compatible.

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 division of 600, so 600...

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 enoug...
