MH721 No pressure, blade won't lift when cutting

Recommended Posts

I'm using a MH721 cutter purchased about two years ago cutting Siser Easy Weed heat transfer vinyl.  I was cutting a design and the machine was working fine until, quite suddenly, the blade appeared to lose all pressure and stopped lifting when setting the origin point or returning to resting position.  This happens when sending a cut from the computer and when using the TEST feature on the machine.  The blade is not penetrating the vinyl enough to weed and is leaving lines when moving to cutting point and back to resting position.  I replaced the blade hoping that may be the culprit, but no luck.  Similarly, adjusting the force of the cut achieves the same results.  Any help would be appreciated.

if anyone needs any for an out of warranty machine (usc offers free shipping if in warranty) I have some $4.50 for 1 with free shipping - $7.50 for 2,   $10 for 3   or   $12.50 for 5 - all are including shipping.
