Need Help!- Do I need to Belt Them Together?

[Mr.Chips]

I'm planning my second machine now that my first machine is running and able to make parts for No 2.

I have two ball screws to drive the gantry, each having it's own stepper naturally. My question is, is it really necessary to tie the two together with a belt to keep them in sync?

Thanks

Mr Chips /Khalid- Congrats -- Me Too!
Khalid your answer was missing - I 'd assume you add the following:
If you are going to use 2 steppers - one per each screw on the X axis - and I suspect you're using MACh2/3 from previous messages - save the belts trouble and set one as the master the other as slave/sync that way.
Bringing back the build one to bootstrap the next! Congrats!
I assume you're planning o direct drive? If belting anyway - (gear reduction ) this approach would require you to build 2 units - one for each screw.

Yes it is two direct drive steppers, using Mach 3 and Gecko G251's.
When you say "set one as Master and the other as Slave/Sync and bootstrap".

Sorry I don't understand. I plan on using two driver cards correct? and the "Master,Slave,Bootstrap/Sync" is a set up in Mach 3, Correct? I checked the Mach 3 index and no listing, also did a CNCZone search and only found Bootstrap refering to "Caps" and electronic componets, but I didn't look at every find.

Could you give me a link to where this is discussed?

I haven't read about any of these terms before.

Thanks
