Re: Hacking the HP45
Wouldn't you only need to patch the capacitor to the ground? That would give you a common testing point regardless of which element you selected.

Re: Hacking the HP45
I'm in for working on the controller - I have FPGA and SoC experience.

Re: ZCorp 310 +
Also of interest: * The controller is a x86 PC motherboard with a custom FPGA card ** The OS is Phar Lap's 'TNT' embedded Win32 API RTOS. * The fast (printhead) and slow (gantry) axes appears to be controlled by DC + Encoder * The fast axis motor controller and printhead controller are both on the f...

Re: ZCorp 310 +
There is a rolling spreader, 19mm in diameter, that spins at approx 250 RPM. (At a 2x slow-mo, I counted 2 revolutions per second, so that's about 4 real revolutions per second, or 240 RPM, calling it 250 RPM) There is no metal scraper, only the roller. The 'snowplows' on the sides are held on to th...

Re: ZCorp 310 +
Had the opportunity to pick one up (broken) for the price of transportation. Took a few hours to get it fixed (new HP10 head, purge binder lines, etc) and it's working nicely. Using sake rice wine and ZP150 powder currently, and it's printing small test objects nicely. Came with the depowdering stat...

ZCorp 310 +
I recently acquired a ZCorp 310 +, along with a depowdering station and a full bin of powder.
If anyone wants me to run some experiments on a 'commercial' powder bed system, let me know.

Re: Brainstorming: Compact piston drives
Agreed, separate powder and feed drives will be in any prototype I make. Only after I have convinced myself that I can run them fully in parallel will I move to a single drive model. I'm going to give the ink + halogen lamp idea a few more goes, but I am beginning to think that a thermal head (like ...

Re: Project Tesseract
I very much like the spring steel bed idea, now that I see it visualized. Some questions: * Are you going to make the spring steel a continuous belt, or a series of plates in guides? * How are you going to drive the spring steel? * If you plan to print in ABS, how do you plan to get good contact wit...

Re: Brainstorming: Compact piston drives
Another option would be to not wind a cable on a winch, but mount cables to a horizontal linear slide. And we have a winner! I like this one a lot, especially as with proper cable routing, this can do both the 'push' and 'pull' operations on the piston plates, and can drive both the part and feed b...

Re: FPGA + AVR for pen control?
I believe BrundleFab's pen controller is a good demonstrator for the 'encoder driven inking' concept. When you get to the point where you are interested in this, I have experience with VHDL and Verilog, and could code up something for you. I'm getting started with a cheap Chinese delta FFM now (taki...
