Hello, Purchased a snap cutter attachment and hooked it up to the 320e press tool. It says to calibrate it first both in the manual and in a bright yellow paper attachment in the box. I tried to calibrate the attachment and it jammed the bottom moving cutter into the stationary cutter so hard that i had to tap on it to free it. I then moved the pin out to the 3" position so the moving cutter would not contact the stationary cutter. This worked ok but the green light was still blinking. I cut 2 pieces of 3" cast as a test but the tool alarmed both times. I know it locks up if i continue to cut when it alarms. Any thoughts ideas from fellow users of this cutter? Thanks.
