ParraPortCNC RevA2.2

PCB color may vary. Currently each board is built to order. It may take an extra day to get your order shipped, thank you.

New revisions are finalized! Boards are now in stock.

What is this thing...

designed to convert parallel port diven CNC's to USB for use with GRBL.

I designed ParraPortCNC because I was tired of using old desktop PC's with the requirement they had a parallel port. The only computer I have that has a parallel port was my server and I could not double duty the server. LinuxCNC requires a dedicated machine to prevent missed steps and processing of your Gcode files.

With this easy plug and play option, you can now control your yooCNC variant CNC from any computer with a USB port including laptops and Raspberry Pi's using any program that knows how to talk to GRBL such as Universal Gcode Sender.

A2.2 has six hardwired lines for yooCNC configurations, all other functions are broke out to test pads that the user can wire up to match there specific setup. The hardwired connections also have a small section on the back of the board allowing the user to cut the hardwired connections and re-wire there own configuration with full flexibility.

The video linked below is a small demonstration of the ParraPortCNC A2.2 working with OctoPrintCNC moving all 3 axis on my Chinese 3020T CNC router.

Specs:
Atmega328 16Mhz.
CP2102 USB to Serial connection.
16Mhz external clock.
Working baud rate 115200.
Compatible with any software that is capable of talking to Grbl.
individually numbered boards.

3D printable enclosure files.

The board comes pre-flashed with GRBL v0.9j and settings pre-configured. All boards are tested for functionality with my CNC setup.

Perfect device for parallel port based CNC machines

This has been a great device for my 3020 CNC machine. I have the skills and parts to convert my machine to use a Grbl or TinyG board- I just need to use the machine and not engage in *another* project-within-a-project exercise. This is exactly what I needed and works wonderfully!
