Re: The Z400 adventure

I do like that tip, I will try that one. I will order the Tween 20 this weekend and add it to the binder.

I will report back when I have results.

Re: The Z400 adventure

I am not yet at the point of throwing the powder away, but it is odd. The part is not really brittle. After a day of drying, the part can easily be handled. It is just that the binder bleeds significant amounts (2-3mm), completely ruining the part. I tried reducing the saturation, but that did nothi...

Re: The Turret

I will not release a build guide. The project is way too big (over 300 hours of 3D printing alone) and too specific for my tools. I will release the files, but with absolutely no guarantee on whether it will work for others. If you are desperate for the files I can put them on the site. 98% of the C...

Re: The Z400 adventure

More time, more progress.

The Z400 prints!



I still need to do a lot of small tasks, but it seems that I can get this machine to work again. More details in the blog.

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...
