Thanks guys, looks like both are good. I actually have a pmdx-122 stashed so it's pretty much even Stevens as to which to choose.
The CSMIO has all 24v digital input/outputs which I think is less affected by noise than 5v. Also it has 2 analogue 0-10v outputs for vfd control so i'm still leaning towards that, but the ESS looks good too! Decisions decisions.

Yes the CSMIO would be my choice if didn't need slaved motors because it's neat and high quality unit. . . BUT will say while 24V I/O's are nice you can still have a 24V driven control E-stop and limit system that is very noise immune if using the ESS or PP.!
The PMDX spindle board will plug into the 122 if spindle speed control was needed and you have it already so ESS will probably workout cheaper and still perform the same or better.!!!. . . . Ermm close call but either way you can't go wrong and both will blow the PP away.!!

Thanks,
Yes a 24v safety circuit is a good idea on either. I just bought a Pilz Pnoz 1 safety relay yesterday off fleabay which I hope will do the job nicely.
Like you say it really is a close call, and most definately the best thing is the PP gets the boot.

I just noticed Jazz's point about slaved motors.
My upcoming build does not use slaved motors, but that's not to say i won't in future.
The CSMIO has an in built facility to slave motors independently of Mach. This however is NOT available in the M version.
You can however still slave motors via Mach with the CMSIO "thinking" two slaved motors are independent axes, but CSMIO-M is limited to 4 Axes so that's something anyone reading this and considering buying the CSMIO-M should be aware of.
WARNING:
Slaving within Mach could be a very bad idea when using the CSMIO-M
Please check posts below for updates, or better still check with CS-labs before making any buying decisions
Cheers

This needs checking carefully thou because every other motion control card I have used takes the duty's of homing away from Mach3, it's a technical issue I think and comes has part of the deal of external motion control.?
So while CMSIO may allow slaved independent axis that doesn't mean it will treat them combined while homing then independent for squaring which is what you need for slaved axis when homing.??. . . . .Best check with Manufacturer first.!!Last edited by JAZZCNC; 06-09-2013 at 12:34 AM.

Ahh, I did not realise that.
So potentially, slaving a motor in Mach when using a CSMIO could be a very unwise thing to do.
Apologies for bad info. Note to self. Check facts before offering dodgy info!!!
I have edited my post to warn and will check with CS-Lab about this

Give another point to ESS,
They really do help if their are issues and once fully set up it runs a dream. When tuning my motors I can get a solid .005 to .01 mm repeats (the DTI and Plunge gauge are calibrated to +/- .01) which literally puts the machine up against the ability for me to accurately measure. That is with C7 screws Zap NEMA23 "24" 3.1 NM motors. Running Mach 3. B.O.B is a PMDX-126 and the power supply is a home built toroidal transformer providing ~68V w/ 15A. It does the job. Have the spindle on the relay on board the PMDX and also a secondary relay off the PMDX so that power is cut during E-Stop.
With Geckos and the Jumbo mode on a PMDX 126 or the ribbon cables you can set up a rather power system if you have the time effort and funds.
