Giant 20' x 3' x 2' router build

[JAZZCNC]

Many thanks for that info again, i will most likely then go for the EM806 drivers from zapp as it does sound like a worth will benefit as the machine is so big in the x axis.

cnc4you nema 23 were as zap call them SY60STH86-3008B, will they in fact be exactly the same? i will most probably get those and the rest of the little parts from cnc4you.

Good idea and I've not seen any differance between the motors either so your good to go there.!

Zapp mentioned that it may be worth running a nema 34 on the x axis with possibly one of there 3 to 1 gearboxes which would allow a direct drive which may simplify things but not sure if i will be able to fit it all in like that without having to mount the motor up top and still have the belt that i was originally planning.

Does any one have any experience with the quality of the zapp gearboxes for the nema 34?

Yes thats what I've done in the past and they are nice units Italian made I believe.? Just be aware thou the Nema34 motors don't spin as fast Nema 23 motors unless running High voltage drives(240V ac) so if your needing certain feeds rates for cutting your foam etc then be sure to select the correct ratio but other than that it's a good solution. Also be aware that the gearbox does make the overall motor/geabox length quite long so check you have room.

Many thanks again for all the help sorry for so many questions but i just want to be double sure on every thing as it is all totally new to me and obviously a lot of money involved in it all that is extremely tight.

Yes but it will be worth the trouble, don't look at the extra expense as costing more think of it in terms of saving money.? You'll only be spending one time not replacing and regreting.! . . . . To quote My Guru Ger21 . . "The cheapest way to get a good machine is to spend more money."
