Re: Hacking cartridge HP 84/85

There are a few ways to do this on a Teensy. The first, and simplest is to write a whole port: https://www.pjrc.com/teensy/pins.html https://forum.pjrc.com/threads/17532-Tutorial-on-digital-I-O-ATMega-PIN-PORT-DDR-D-B-registers-vs-ARM-GPIO_PDIR-_PDOR?p=21228&viewfull=1#post21228 This way you can set...

Re: The Z400 adventure

I have been keeping track of the progress on the Z400 as a blog. It can be found here: https://ytec3d.com/the-z400-blog-part-3/ TL;DR: All power supplies and HDD are tested and work. The transformer is installed and the machine has booted for the first time. Now there is a big list of mechanical poi...

Re: PowderMaker1 3DP printer

How does this "official" powder behave compared to what I have in Oasis right now. The stuff in Oasis is an older Zcorp "official" gypsum. If you just pour it it can keep angles between 45 and 60 degrees, but is loosely bound. It can then be compressed to what feels like between 2/3 and 1/2 its orig...

Re: The Turret

That was quite a wiring job. _RUQHRmWkD0 fRYzQhVv-Lk But the turret now shoots. I spent the last few weeks wiring the shells. The wiring was quite a bit more work than expected. There are 4 flywheel motors, 1 tilt motor with feedback, and 2 feeder circuits with adequate redundancies. The side is wir...

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?
