General Mach Discussion / Re: Optocoupler for limit switch problem

USB connections for an external motion controller with Mach3 are 'noise prone' and it is unlikely to be truly sucessfull when using an 'electrically noisey' plasma torch.
My opinion is that the problem is not with your limit switch connections but is related to the USB.
The best long term solution I can think of is to swap out your motion controller for one that uses Ethernet connection such as (and just for example) the Warp9TD ESS Smoothstepper. There are other (Ethernet connected) motion controllers available but make sure you choose one of EU or USA manufacture and steer clear of those from China.
