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 ...

Re: Modifiying Creality Ender 3 with Plan B

There are few companies that make piezo inkjet. Epson and Xaar almost by definition make piezo inkjet, HP and Canon almost by definition make thermal inkjet. Pinouts are always challenging to find, since this is not open technology.

Re: Hacking the HP45

Hello, I myself have little experience with identifying printheads. I do know there are subtle differences between several variations of printhead, one of them the HP45, and expect that there is something in the background that allows you to identify heads. I however have no facts on this. What prob...

Re: Modifiying Creality Ender 3 with Plan B

I do not know any, since the C6602A is a bit of an odd printhead. The closest thing I know is the XAAR 128, but it already has 128 nozzles, and a serial interface.

Re: Modifiying Creality Ender 3 with Plan B

Hello Plan B firmware does have all the handling for motion and inkjet combined. That is however everything that matches. Also be aware that even now I am not a great programmer, and in the Plan B time I was an even worse programmer. I cannot guarantee that modifying the firmware will be simple. 1. ...

Re: Hacking the HP45

How many amperes consumes HP 45? Each nozzle does 300mA, and I can fire at most 5 at a time, so the peaks are around 1.5A. Average should not go above 1A. @inkjet: Your schematic shows a pulldown on the address. However, my experience is that I needed separate resistors pulling down when I used led...

what is the speed of spitting HP 45
how fast can they fire?
what speed did are you achieve
I manage 50mm/s at 600 DPI. This gives 1200 firings per nozzle per second.
