Anyone have any experience with these boards?

(The C79 and C80 are supposed to be the successors to the C31, which I was considering using.)

Just did a quick browse and the amount of writing errors is huge !
On pictures there is always written "outpus" with the missing T, somewhere it is writen that you need a power source of 24V 200A !!!! etc etc.
Back on topic, i have not used them and i am sure it will work but how fast will it work remains to be seen.
Last ones i got from china are collecting dust in the workshop as they are to damn slow, parallel port is leaps and bound faster. I gave up on using BOB's all together and just wire everything directly, a bit of care not to mess up grounding and never have any problems.

I've always had good luck with CNC4PC's C10 boards in the past, but I have to agree that manual is awful, looks like it was typed up by a 3rd grader (or my mom), no proof reading what so ever, lots of obvious mistakes.

If that manual is any indication of the quality of their new products, they might be best avoided. (I hope that isn't the case.)

I have used the GTL2010
www.nxp.com/products/analog/interfaces/i...translator:GTL2010BS
But that is for translating between 5V and 3,3V (and lower)

You might be able to use a ULN

I've made some progress.

First, the C80 board was a bust as far as trying to use it to run the machine. It's opencollector outputs just weren't practical to trigger the drive steps. It's 24v inputs were useful for snooping the output signals from the old control. With that I was able to confirm the step patern is 1/2 step unipolar and even measure the step scale and velocity/acceleration.

So I popped the cover off the old control and looked over how it works. It uses a chip L239E to send the signal. So I bought 4 of these

With them I am able to trigger the drive steps using an ordinary 5v breakout board for a parallel port.

So far I've tested moving 1 axis with Linuxcnc using a breadboard setup. After I test the full setup, I will solder up something permanent.

For anyone searching for this Information about a Gerber D-200 or Gerbers Arc Stations. The pin-out of the D-37 port is:
Code:
Pin# Voltage Description 1 24v X-Phase-a 2 24v X-Phase-b 3 24v X-Phase-c 4 24v X-Phase-d 5 0v Common (Pins 1-4) 6 0v 7 24v Y-Phase-a 8 24v Y-Phase-b 9 24v Y-Phase-c 10 24v Y-Phase-d 11 0v Common (Pins 7-11) 12 0v 14 24v ? 15 ? ? 16 ? ? 17 ? ? 18 5v 5v in (pin 18-19) 19 5v ? 20 24v Spindle Relay 21 ? ? 22 24v Spindle Trigger 23 ? ? 24 0v Common (Pins 20,22) 25 0v ? 26 24v Z-Phase-a 27 24v Z-Phase-b 28 24v Z-Phase-c 29 24v Z-Phase-d 30 0v Common (Pins 26-29) 31 ? ? 32 24v ? 33 ? ? 34 ? ? 35 ? ? 36 0v ? 37 0v ?
I can run the machine with full functionality using only pins 1-5,7-11,20,26-30. At this point I do not know what the pins with the question marks were intended for. They don't appear to be used for this application of the Gerber Arc Station.
The home switches on this machine (only X and Y) are 5v magnetic reed switches and run off of a separate plug that goes directly to the Arc Station.
