Re: Generic powder machine controller

Hello David, I like the idea. For what printheads are you designing this controller. With FPGA at 300MHz and 15 free I/O (and 42V) I can easily see the Xaar 128 on this, but something like the HP45 will not work on this, it simply needs more I/O (around 20). Is the 15 channels limited by your curren...

Re: The Turret

Movement W86etRMzjak (Sorry for the vertical video) I finished wiring the open and pan motor. It took a while because I also got a new 3D printer while doing this. The guts of the movement is the pan/open mechanism. The whole mechanism pans, and inside is a scissor mechanism that opens and closed th...

Re: The Turret

A month later, this post schedule is getting out of hand. I will post the past month in a few separate posts, else this post will be too long. I spent the past month doing several things. Mostly rewiring the main body and printing the left shell of the turret. Today is the left shell. A bit of backg...

Re: Problems with SD card

If you clean the head again and it is a different nozzle it might still be clogged. The printheads can be a bit tricky if they are older. You can also try a different printhead to verify. If it really is only nozzle 6 and nozzle 6 every time, it might be a connection that is off. What connection or ...

The Z400 adventure

The sequel to https://ytec3d.com/forum/viewtopic.php?f=8&t=5627 . I now own a Zcorp Z400, given to me by Wonko (Many thanks). It currently resides at my local hackerspace, the Tkkrlab, where I hope to restore it to a working condition. IMG_20190303_172047.jpg I will give a TL;DR here, but below I wa...

Re: PowderMaker1 3DP printer

That is looking really nice. It looks very solid. The thing on the printhead looks like an ink buffer. Is that correct or is that something else. What printhead are you planning on trying first?

Re: Hacking the Xaar 128 printhead

Looking very nice. No obvious blurring or missing lines. Is the speed currently limited by anything or are you printing at this speed because it is easier for now. I am not really familiar with the damper. What is it's purpose. Is it there to smooth out the flow of ink you are pumping to the printhe...

Re: The Turret

A few more weeks, a few more progress. DSC02308_LW.jpg I first tore out all of the wiring that was in the turret. This was a mess that I did not even want to fix. I then started to rewire the turret (this time with an actual design beforehand). The basics are still the same. There is a 12V/30A power...

Re: Hacking cartridge HP 84/85

Is the hole you pointed to in some way connected to the printer? I suspect the bellows exist to pressurize the ink (or maybe even to create a vacuum), but that would only be possible if that hole is connected to the printer in some way. In any other way it is pretty similar inside to most other prin...
