RE: [CAD_CAM_EDM_DRO] Re: plasma setup-leadscrew vs. rack & pinio n + software

Hello, Ballendo,
I saw once on this forum, roller chain is NOT enough linear for CNC
machines.
So, you recommend it again ?

And, I can't find an email address of Plasmacam, Inc on plasmacam.com. Do
you have it?

Hello,

Roller chain (#25, or even bicycle chain) can work really well for
plasma. Fix the chain at both ends, and move the motor/sprocket. An
idler sprocket or two adds "wrap" to the motor sprocket. If your
motors are small, try a 4:1 reduction before the final output. BTW,
this will work for routers too...

Hope this helps,

Ballendo
