I'm currently trying to decide what motion controller/BOB combo I'm going to use for my new router build.
I'm going with 3 axis, dual stepper on x-axis, so I need slaving and at least one extra axis to add a 3d printer addon (I know, not the best 3d printer).
I can't really decide what to get at the moment, probably leaning toward either an ESS + some random BOB or a PLCM-E3 with some BOB (currently undecided). ESS is hard to get in EU though.
Lo and behold, I then stumble upon a board called PLCM-E4 on purelogics site. It appears to be a slightly slimmed down version of the E3, but with a BOB integrated.
http://www.purelogic.ru/files/downlo...er/PLCM-E4.pdf + google translate works pretty good.
What do you think? Should I send an email to Purelogic, see if I can buy it?
Or, should I get a PLCM-E3, if so what BOB should I get?
http://www.zappautomation.co.uk/elec...out-board.html looks like it's both the B1 bob and an E3 if I go by the pictures and the price tag, but the description is rather vague. Does this include the E3?
I realise this is a bit of a ramble, but I'm rather confused at the moment, trying to decide what to get. Cost is a bit of a concern, and I wouldn't want to spend as much on a bob as I do on the motion controller as it seems like some people do.

I'd enquire about the E4 but got a feeling it's still in R&D.
The B1 is just a BOB but it's designed to take full advantage of the E3 and allows full use of all the I/O. It's essentially 2 Bob's in one with PWM spindle control.
If you don't need all the I/O the E3 provides then you can get away with just using the PLC6x or the PLC4x-G2. The G2 provides PWM spindle control the 6x doesn't.
If your going for the ESS then I'd strongly suggest you go for the PMDX126.

I was getting a bit confused about this as well, when I was looking at the Zapp site earlier (and especially as I haven't found decent English documentation for these devices). Thanks for the additional info.
One more question, though - when these boards talk about PWM spindle speed control, I am assuming that they have some kind of PWM->true analogue converter on board, which takes a PWM speed signal from Mach3 and gives a 0-10V (usually) signal that connects directly to the VFD. Is that right? Nothing else needed for Mach3 spindle speed control?
