Hi Guys,
I've got a G540 and I'm looking at adding more outputs to it. i.e. I would like to add mist and potentially another output so I can reverse the spindle (not really sure when I'll use this but might as well make it). Anyway, any suggestions on how to rig this up? Any suggestions in terms of
1.) Additional PCI cards with D25
2.) Breakout board
3.) How would I go about controlling the pump/compressor
Has anyone got any links to their systems?
Add a pokeys ethernet board.

Shouldn't cost you more than $25.
Good point ger .. I had forgotten about PP cards, as I have not used any in maybe 6 years..
BUT..
And this is actually important, an ethernet interface is electrically isolated, and this gets increasingly important as more signals get added.
Yes, ethernets are isolated from the PC, by spec.
Also, pokeys gives you high speed 300-500 kHz input and output signals iirc, can read high speed encoders, and add about 20 inputs/outputs, not just a few.
And its only 60€ or something.
Great drivers. Good support.
By far, best bang for buck available. Anywhere.
The best bar none, is the CSLabs stuff, but its a bit expensive for a big industrial system like mine, about 1500€ all in.
CSMIO-IP-S, mpg module, encoder module, 200 IO, 24V, dual 24V DC isolated PSUs, large case, 1500 ferrules used, DIN rails, etc..
But it is the best, and 4Mhz, noiseproof, runs my 750W and 2.5kW servos, 30.000 count/turn encoders, etc etc etc.
Pokeys is best and cheap.
CSLabs is the best, period.
PP is cheap, and for only 1-2 signals, fine.
But electrical issues creep in, especially doing 0-10V speed control, and you cannot run real servos etc.. due to limited bandwith on PP driver.
I need/use 500 kHz on my servos, typical, 10.000 counts/3000 rpm = 500 kHz.
Pokeys supports 125 kHz on mach3, more on mach4 iirc. and at least more axis on mach4, 6 axis vs 4 on m3 (3+spindle).
I use step/dir servo spindles, so I need min. 4 axis, lathe will be 6-7 (now 3), and grinder will be 9ish (2 pokeys).
