I've been away from the ShopBot for many months. I needed to cut some arrows out of 1/4" PVC so I'm trying to remember the procedures. I noticed, without running it, the "X" axis motor is Hot to the touch, Y & Z are cool. CNC is just sitting there, turned on, but not running. Also having issues with A Message: ''The remote stop button connected to input #4 appears to be on''. However, the stop button is not on. Any help with these 2 issues would be appreciated. Thanks.
