As title says, our Wizard 5000 is pulling the mats out of the left side vertical air clamp. Bought a used 5000 in pretty good shape but it had a few issues. Needed new air clamps for one thing. New clamps installed and other things adjusted, (overcuts, backup,etc...). Anyway, the issue is that when cutting tall vertical mats. The head starts in the lower left as normal then goes vertical to the upper left corner. Makes the turn to go from the upper left corner to the upper right corner. This is where the problem occurs. When the head makes the transition from vertical to the horizontal position to cut across the top, the pressure from the head retracting and reinserting the blade causes the mat to pull out from the left air clamp slightly. On a single opening it's tolerable, but when cutting a tall vertical tiled mat, say 3 instances, by the time the last mat is being cut, which is the one closest to the air clamp, the mat has been pulled out from the air clamp. When the head start it's horizontal cut across the top, the mat is out of the clamp and I'm trying to hold the mat by hand, but then the head turns to do the down cut from UR to LR is really bad. usually the mat buckles at this time ruining the last mat. I've tried pausing the cut to reset the mat in the clamps, but when I release the pressure, the head is released to and cutter forgets where it's at. Question is, is there a pressure setting for the head/foot pressure to keep it from applying so much pressure it yanks the mat out of the clamp? I've felt the 8500 wanting to do the same thing when it makes it's UL to UR transition, but it usually didn't fully pull the mat out. I still had to hold the mat and sometimes the mat did buckle so it seems to be a design issue but is there a way to adjust this to minimize it?
