General Mach Discussion / Re: I've got CV Brain lock... I know even less, now... Help!?

Basically, the faster the feedrate you're using, the faster the accel needs to be to prevent rounding.

What Distance tolerance does, is basically disable CV mode when you get within the specified distance of the corner. Just guessing, but I believe that if you set it to .001, it will act very much like Exact Stop mode.
Imo, your best option would be to lower the CV angle below 89. depending on your toolpaths, you may find that you get better results with it set at 60, 45, or even less.

The oscillating issue your seeing is due to a lack of rigidity in your machine. There's no substitute for a powerful, rigid machine.

1) Mach3 can not do 3D radius compensation. (I'm not sure if any controls can, as they wouldn't know where the actual part is).

2) If you have the correct tool information in MeshCAM, then the g-code should be offset from the surface of your part by 1/16" everywhere.

And if your goal is to have your home position (Machine 0,0) in the  center of the table, you can use Home Offsets to achieve that with the switch at the end.

I don't think that you can.

so when you hit a limit mach gets rid of your zero you set?? why would it do that?

Because a limit switch is an emergency stop, and Mach3 will instantly stop sending steps, which causes the motor to lose position, as it doesn't decelerate properly.

How you restart depends on how you started in the first place.

No, you have to jog it off the switch yourself. You need to turn on either manual override or automatic override before you can jog off the switch.

A Mach3 post processor, if there is one. Otherwise, try a generic g-code or generic fanuc.

5mm pitch = 5.08 turns/inch, x 200 steps/rev x 10x microstepping = 10160 steps/inch.

Also, some plugins may only work with certain versions of Mach3, and with Chinese devices, they tend to be older versions.

Don't really want to go back in time, sure the older versions have their glitches and bugs that were hopefully solved by the latest version. 

Actually, the latest version is known to be very buggy, and most recommend using an earlier version, like the ones you tried.
But I would be surprised if the chinese plugin requires a much older version, like 3.042.*********

if you look at the plc and other bits they have a on off for screen buttons, axis`s but not jog it probley needs a on/off for jogging to not work when the machine is not enabled if its not the screen jog being used that is disabled a different way

No,this should not be in user accessible code. When it's disabled, it should be disabled, an it should be done where it canct be changed.
