i get the following codes sometimes while running. Sometimes by clearing the code will help, sometimes re-homing, and sometimes by turning it off and restarting. That sucks because then I have to start over...
Anyone know what causes or why I get it? I've blown out all limit switches, cleaned out the E-stop and out of ideas...
Thanks.

Re: Limit Switch Errors
If you've had your machine awhile, the best solution is to replace the switches. Limit 0 is the X axis and those switches are on the ends of the gantry beam. I oversee three Probotix CNCs and my students have a tendency to jog the Z axis to the top before homing the machines which eventually bends/fatigues the Z switch until it can open up easily with vibration during a cut. The X axis on our Nebula is also finicky. Sometimes pulling off the cable ends and giving the switch terminals a quick scratch with steel wool will help, as will squeezing/crimping the connector a bit once in place. In some cases we've eventually just soldered the cables to the switches.
Let me know if any of the above helps.

Also check the grounding between machine and computer. If the ground is not very good, you can get some false switch readings.
