Re: [CAD_CAM_EDM_DRO] Re: [Emc-users] No Torque (power?)

Weyland,

you are not using a lighting transformer are you?, if you are that could be
a problem as they have a thermal cutout switch and in most cases wont supply
enough amps for even 3 x size 17 steppers (under load that is) ( i know ,
Ive tried).
