Description of Issue

A Y-axis stall is caused when the difference between the commanded distance becomes much more than the actual distance over the allotted time interval.  An easy example of this would be putting your hand on the cutting truck and preventing it from moving during an operation.  The computer is commanding it (and expecting it to move a certain distance in a given time interval) but your hand is preventing it from moving; or stalling the movement.  A stall does not have to be a physical obstacle to movement.  For instance if a power lead to the motor was broken then the motor would not move when commanded and the computer would record a stall.

Possible Causes

Causes include: obstacles blocking the movement of the cutting head, outdated firmware, faulty electrical circuit in the shop, and electrical short in the machine, a loose connector, a faulty power supply, or a cut motor that is not spinning.
