ever time I set auto zero the router lowers touchs the plate then raises to hits the limit switch. I have to home ref and start over now the router its self will not turn on. It works five if I plug it in by itslelfs. I have unstall mach3 and installed agan. If anyone has a suggestion I'am all ears.

Could you please post the code that you are running to auto zero the tool? I think we can find a way to make it work

Thanks
