Hi Irfan

How is your big router building? I've been watching your posts yet from machmate forum. Me too who got stuck with servo (before learning prices for reducers) . The only difference - I've bought drivers and now looking for motor + reducer affordable solutions. Going to build cnc similar design and size as yours.
I see you've got quite big motors. Is so big motor for X really needed? I've made a spreadsheet for calculations and it seems moving some 90kg gantry with twice lesser motor possible... Any suggestions from you (or anybody reading this)? Hope nothing wrong with my formulas. I only don't know efficiency (factor) coefficients for belt drives, what practical "t" (acceleration time) and cutting forces are (wood, 2-3hp spindle).

Oleks, when I purchased my motors I was not sure what I should buy!

it was just made on instinct and my foolishness!

Now I have decided to use those motors on differently designed router where I have used ball screws.

and for the material I have used for this router I will utilize this for building a mechmate.

I have purchased steppers to keep up with the original design.

I think you values on excel are good enough, though I havent gone thru them entirely!

u can see my other build at http://www.cnczone.com/forums/showthread.php?t=46998

Good luck for your build.

Irfan, I was unaware of your this built......Very nice work u did so far... Why you start the second machine before completing this one???

[contactirfu]

Bcos it was going haywire, the time and money spent of that machine were just not justified and i then decided to go the mechmate way!

Just same thoughts attend me - to cover expenses and delivery costs have to oder set for two cnc and make one for sale. I see in Ukraine and Russia 2-3 years ago there were more discussions on cnc forums than now. I suspect that most gays who made good one started to sell them.
Here is most professionally designed DIY CNC with ball screws I've seen in the web. Some info there very interesting and may help you some day.
