I have been using a gecko G540 on a CNC router for over a year. We recently changed the table from a 4' x 4' to a 5' x 10' table. Then we started to experience recurring faults and E-stop reset messages on Mach3. Now we get a reset message occasionally when we move the Y axis. The X and Z axes work fine. The G540 red fault light comes on and the power green light goes off when movement stops along the Y axis as the result of an e-stop. We also experience an unusual phenomenon during a rapids command. When executing the following:
G00X10.8125Y78.5000Z0.2000
The router moves the correct distance along the x axis, but makes no movement along the y axis. The router also seems to drop at a slow rate along the z axis while moving in along the x axis.
We eliminated the limit switches as the problem by shorting them out during a trial run with no perceptible performance change.
Please provide any troubleshooting advice you can.
