A question I get asked a lot is what happened to the power armor project. (WARNING, big post alert) This is what has happened: IMG_20160514_212148.jpg IMG_20160514_212203.jpg IMG_20160514_212212.jpg I lied, only a few people ask me about it. But I keep a record here, so here is the current status of...

The main challenge for Oasis is that I do not want lead screws and guide rods in the pistons. Mechanically speaking, guide rods and lead screws make the piston design a lot simpler, but to get a stroke of n, you need 2xn plus some additional space for mechanisms to make it work. This means that if I...

There are 16 primitives and 2x13 addresses. Multiple primitives can be on at the same time in a trigger. Addresses are different. Only one is on at a time, always in the same order. the first 13 addresses are used from the first head, then it is switched to the second head and goes from 1-9. The chi...

Not at all, The L6452 has the electronics for 13x16 for 2 heads. This is 16 power lines and 2x13 address lines. By using address lines for both of the 'printheads', a single HP45 can be controlled with pins to spare.

I did a lot of thinking on how to make the floating Y-axis construction stiff enough for practical use. I now have a concept that might work. First of I reinforced the X-axis and put both axes in the back of the frame. The rods will be somewhere between 10 and 12mm thick. On the X-axis are 2 thick b...

No pretty schematics today, but a plan for the foreseeable future. I ordered parts today from several sources. I ordered: L6452 chips TLC59213 (SMD) MIC5891 (SMD and DIP) LM311 (SMD) SIRA whatever mosfet (SMD) parallel SRAM (DIP) additional pogo pins PQFP100 adapter (hard to find) And somewhat unrel...

Mouser sells them per 1 and has them in stock. This is the most curious chip I have ever seen. It really seems to be a full inkjet printhead driver chip. It has too few addresses for the HP45, but it is designed for 2 heads, so perhaps the remainder of the addresses can be taken from the other halve...

The reason why I was still doubting was because the horizontal Y-axis has nothing on the back. The circuit of the printhead is pointed that way. I will probably keep it vertical for now, because it is better. In the pistons there is one wire in the middel pulling down. It is this wire that is spring...

I agree that cables should be bent as little as possible, but it is not something that should not happen at all. How much it bends depends on how the circuit fits, not the other way around. I did try it vertically and it does work quite well, so the cable is for now vertical. The endstop will always...

I have gotten far enough with the HP45 that I can start with a new printer. I need something to test electronics and firmware with, and I might as well make it the functional printer I was planning to make. But first briefly what I have learned form the previous printers: Focus: http://ytec3d.com/fo...
