Cal ...I assume.

The weight of the torch plus lifter assembly plays hell on thin gauge plate as it rolls over the cutting slats. sometimes enough to crimp the sheet leaving dimples all over it as the balls roll across the slats. It also has a tendency to move the sheet around. If the sheet is clamped in place, there are no drop parts within 3 inches of your cut path and the steel is thick enough to support the weight the the roller ball floating head is dandy. Otherwise go with the auto height control. The one qouted only has a 3 inch stroke Drive and control is contained with in the motor and was a bear to get to work right when we first played with it...but it works fine after rodney got finished with it.

When I implemented the card in a system I would always use this feature. Al.

Those were some bad times for engineering back then. When the price war started they tried to do many things and unfortunitly most of them wrong.

After some shake up in engineering they got their crap together and came up with the milinium line that is for all pratical purpuses ...perfect. Everything engineering did had to be approved by the Field techs. They even stole our best one!!

I installed the second mastergraph milinium in Va. after two years of operation it had lost only .002 in the cross axis X and .006 in the Y. Still running strong after 10 + years.
