	Some materials, especially certain plastics, create excessive static electricity when cutting. It can be exaggerated when using a shop vac or dust collection system. Running a bare ground wire through the dust collection system can help alleviate this issue.		Some materials, especially certain plastics, create excessive static electricity when cutting.

		+	=== Too Tight ===
		+	If the switch has recently been replaced, it could be screwed down too tightly. This would cause the outer casing to squeeze the spring inside effectively holding it in place.

 If you accidentally drive into a limit switch before homing the machine, no need to panic. Follow this procedure:
-# Click the small grey [x] in the lower right corner to clear the error.
+# Click the close button [[File:Close.gif]] in the lower right corner to clear the error.
 # Place a check mark in the box labeled "Override Limits"

 # Then you will have one jog maneuver to get off of the affected switch.

 The Y limit switches are removed for shipping and may not be as tight as the X and Z. If you are tripping the switch when you are nowhere near it, or it's happening randomly, you may be experiencing one of the causes listed below. Try blowing out the lead screws and switches before checking the connections again. If you still have issues contact PROBOTIX and we can send you replacement switches. If you would like spare switches or are not under warranty we offer them on our website.
-If you have any bad switches and no replacements, you can temporarily disable hard limits in the configuration using the [[NEW LinuxCNC Configuration| LinuxCNC Configuator]]. This will use the switches for homing only. You may need to rearrange working switches so that homing works. Contact support if you need help deciding this.

 Did you hit the wrong jog button when trying to jog off of the switch? Still no worries, it will error out again, simply follow the steps above again.

-The Y limit switches are removed for shipping so are not as tight as the X and Z - if you are tripping the switch when you are nowhere near it, or it's happening randomly, you may be taking too rough a cut causing excessive  vibration, the crimp terminals on the switches may need tightening, or there may be some dirty or bad contacts.
