5 axis 9 stepper mesa board selection

Well.....looks like I have one of those optoisolator ones which are blah....cant get it to work at all. Still feel like something might be wrong in the hal/ini files as it wont budge one bit. 

Have another board, like the one listed above, arriving tomorrow...will give that a shot.

Included are the hal/ini files

Yeh, the 1205 boards are Blah! Thats been discussed before. I just threw mine out this morning....

Regarding the opto interface:
There is a high speed variant available with a high-speed optocoupler (6N137).

That was it..... Was able to get all 9 steppers moving with the 7i96s and the bob with the relay shown above .... The only thing is I can't seem to get the input working when it worked fine on the other card. Will double check things again and see what I goofed up.

Thanks for the help everyone! Look forward to that rs485 mesa driver! Let me know when you need a guinea pig to test.... I'll be happy to.

"A bit of warning, not sure what the situation now is with G540, but the old ones had division by 10 inputs, so for precission stuff it was not good, hence i stopped using them. Pitty as they are a capable neat package and i newer understood why they did that, nor got a reasonable answer from them back then. "

I have a Taig mill with Linux 2.7.14 on an Intel J1900 processor and an old G540 that has been dormant for years. The latency test with Linux Live 2.8.4 is unacceptable and the future of the RTAI kernel seems uncertain, so I was thinking about a Mesa 7i76 or 7i92 for use with the G540. In view of your experience perhaps I should replace the G540 as well. What would you recommend for use with the 7i76 for driving Keling hybrid steppers (KL23H284-35-4B)?
