giving away my ZCorp Z400 for free
@dragonator has first dibs. I am giving away my ZCorp machine for free to whoever is willing to pick it up near Düsseldorf, Germany. Please contact me at z44@matthiasm.com I bought it many years ago with a fried ribbon cable to the printhead. In all that time, I found replacement ribbon cables, repl...

Re: color 3dp slicer software
I wrote a slicer that can do just that. It is by no means finished, and the current version has the texture stuff disabled because I was trying to control a mixing FDM printer first, and then finish the texture stuff. If you are really interested and have a printer that would work with this, I can s...

Re: Hacking the Xaar 128 printhead
I used some unbranded oil based ink. Water, that I first used for testing and drove me crazy, because nothing worked, well, water does not work. Just search the net for "xaar 128 compatible ink": https://www.independentink.com/a01017bk.html for example'

Re: Hacking the Xaar 128 printhead
I'd be interested in the PCBs mentioned earlier.

Re: Zcorp Z402 project
Mine did print a Sake Sugar model years ago. If you like, @dragonator, you can come over to Düsseldorf and take a very close look at and inside the machine and all its working parts... . No clue where @emptyset is located though ![Wink ;-)](./images/smilies/icon_e_wink.gif)

Re: Zcorp Z402 project
Good luck with it. I have had one for 10 years or so. The printhead are made from Unobtainium. The ribbon cables to the printhead usually rot away from the binder chemicals. The harddrive in the DOS circuit board in the back of the machine will probably not last very long, so you should make a disk ...

Re: Hacking cartridge HP 84/85
Here is an example to toggle bits as fast as possible using assembler: https://forum.pjrc.com/threads/31350-Maximum-GPIO-toggling-(Teensy-3-2) You can modify 8 or even 16 bits with a single instruction, but you have to prepare the patterns that you want to send. There is also an instruction to set o...

Re: Hacking cartridge HP 84/85
Serial.println(...); will take forever in the context. If you set 19200bps, sending a digit plus a newline character will take 8 bit per character plus start bit plus stop bit times two, or 19200/20bit = 960 calls per second maximum plus overhead. A microcontroller is different to a PC. The serial l...

Teensy uses an emulation program to allow for PORTB and PORTD commands, because Teensy has a different CPU.

Re: Hacking cartridge HP 84/85
Arduino Due has the same shape as the Mega and also a faster ARM based CPU and 3.3V. I forgot to mention interrupts. To keep the serial port working and a few other things, Arduinos use interrupts that - as the name says - interrupts the flow of your program at any point in time. For the duration of...
