Usb smooth stepper

To clarify - I think that you are saying that the PLCM-E3 can handle a twin-motor X axis? That would make it a bit more useful than the CSMIO-IP-M and cheaper than the bigger CSMIO version that costs a lot more, even if it doesn't include BOB functionality.

Yes PLCM-E3 can handle Twin motors and I did say at the beginning "It's only draw back is doesn't support slaved motors" this is the only down side to the IP-M version for use with routers using slaved motor setup but in every other way it's far superior to any of the others. Also remember there are a lot of people out there who don't use slaved motors on routers but still want motion control cards.
It's bigger brother that does do slaved motors isn't really in the same market or aimed at steppers and is aimed more at servo's where again there's very little to touch it in quality and performance at that price range, you have to spend a lot more to even get close matching it.

For Twin motors the PLCM-E3 is a cheaper option and like I stated it's what I now use on slaved motor machines. I used to use ESS + PMDX which I still very much like and would recommend and use if could buy cheaper in UK but not since prologic brought out the dedicated BOB with spindle control, Which you couldn't do at one time without PWM spindle speed control board or BOB with one fitted, then I've started fitting these after testing for over a year on my machine. (I won't recommend or fit anything I haven't tried to kill first.!!)
