can two belts be on and the motor run?
Yeah.
Can two belts be on and the motor stalls because of friction on the belts?
yeah.

can one win over other?
yeah
does the stronger motor always win in a belt drive mismatch?
(schtum OP uses two drive belts in gear belt wheels of different gear. Or this is test gear with belt wheels added.)
No.

at DriverPacks, we saw that the shorter the string, the stronger it is.
let us suppose each manufactor gets a color.
more detailed string is good, if providers don't keep using each other color for their make.

the shorter string will soon match a search.
the exact string is so much tied to this pinkish vanilla smell with violet overtone and a twang of KiSS that modern search takes two hours on local drives, and eternety on the net.

gear boxes don't work without oil.
Help us help you.

This one is a weird one?
What happens with one motor on same axle, when you put two belt to the gearbox.

jaak is saying if the driver is not in the pack give us a link and we will add it

Pete Hawkshurst sounds like a BRit name to me.
Pete? Suppose I run a search to all of the downloads we ever had, and I do NOT find the Pci\ven_168c&dev_001a&subsys_2052168c&rev_01\4&1a598d38 you have, then I have wasted almost hundred minutes search on a terabyte drive.

Can you at least please let us get a driver download HINT?
we know we can sometimes make things work, but if it won't mesh, it won"t.

mesh is not a verb. why is is used as?

you are welcome to try the SAD feature of DriverPacks BASE with the LAN pack.

Thanks
