Re: Standalone controller V4.0

@Dragonator Print quality of this version looking promising. I am very much interested in how it's working , i mean spi to parallel outputs.

When could we expects the firmware code release. Eager to learn about its mechanism

Re: Standalone controller V4.0

@Dragonator Printing quality is seems okay compare to previous oasis 3dp version. Any special requirement of spi protocol. I think it's reducing the pinouts but increase the source code complexity.

Re: Standalone controller V4.0

Instead of TLC51923 ic , i have found Microchip HV583 of which is capable of driving Inkjet heads as well as it has serial to parallel gpio interface for driving. Also I was guessing your code to driving print head using serial data previously when I studied oasis 3d code it was divided into two par...

Re: Hacking the HP45

Is anybody heard of XMOS microcontroller. As i have read it has parallel processing capabilities with programmable I/O control. Its mainly a software based control. 200mhz operating frequency is useful when we deals with timing critical signals. I hope it would a better alternative to FPGA as well a...

Re: Hacking the HP45

I cannot judge whether the pins are connected correctly, but overall it seems like the right thing. I would lower the delay between clock 1 and clear 0 to 2 microseconds, but other than that, it seems fine. Do wipe the head before printing. It will literally not work without it. Other than that, I ...

Re: Hacking the HP45

If you are manually triggering, you will need to open the mosfet. Testing it is somewhat complex, but what I usually do first to not have a printhead in and turning known pins high or low. I then measure the right pads to see if there is 12V compared to the ground pads. This is simpler without a co...

Re: Hacking the HP45

Hello and welcome Priyashree Do you have any schematics or images of your circuit. The 4017 circuit has not really ever failed me, so I am curious how you are doing it. Dear Dragonator, I have used the schematic HP45 standalone version 3.2 as well as ordered PCB from local PCB manufacturer. I didn'...
