Let me know if you want some more information.

I'm definitely interested - those ratings should make it pretty indestructable! Do you have a datasheet or something for them? Is it sensored or sensorless?

Hehe, I hope so - just spent £274 on linear bearings and ballscrew so I've not got much money left!

P.S. I vaguely recall you posting about these before..?

PoKeys

That does look good, but very expensive compared to PCI parallel port card on eBay for £3.52.

Mark, I don't know how much control the software you are using allows but one thought on conjuring up a second X home switch is to mount a single switch on the Z axis such that it 'makes' against an edge at the 'home' end of the table.

Drive the Z to the far left and you have a 'home' for the left X screw, drive the head to the right and you have a 'home' for the right screw. Not ideal for the final design perhaps but it certainly gives you some way of tracking the racking while messing around :)

Jonathan while it is correct that you can buy cheap PCI Parallel Port cards on Ebay they don't all work with Mach3 some don't have the option of using pins (2-9) for input or output. The PoKeys has dedicated drivers for Mach3 it even has a sub forum on the Mach3 support site.

A bit like comparing a Tata Nano against a Ferrari they both have four wheels, one is a lot more expensive which one would you prefer. ?

Just a quick question ... Any idea if it works with EMC2??

If you are talking about the PoKeys in theory yes as it is classed as a standard USB device.

But it would need someone to build the the driver whatever and i am not that person, the EMC2 has other options that mean the best guys do not want to bother and Boris the seller of the Pokeys doesn't have the desire either sadly as i have already asked him.

Cheers Phil, I know a EMC guru ... next time I catch him back in the UK I will ask him ... could be an interesting exercise ...

I have had a good look at EMC2, being a guru is a minimum requirement. LOL

I am on the mailing list, i think they talk Klingon, goes way over my head.

Same here ... that's why having a guru around is useful, that is if only he would stay in one country for long enough to have a conversation!!

Tata Nano against a Ferrari

think ill go for the nano, i can afford it

iv weighed up all your posts and its all getting a bit rocket science so im going for the simple and cheap option
iv orders a pci ribbon extender and a pci parallel port, i should be able to sneak under my graphics card with that

all that for one more input
