I would like a message box to require confirmation before I crash the mill or plow an end mill in to a fixture.

A description of the crash before I select "OK" would also be nice, but not a requirement. :)

Seriously, I'd really like the "run from here" to use machine coordinate Z0 as the start point. As it is, each program requires a different safe Z height depending on the part height.

That, or I still don't understand how the run from here function actually works.

I find that jogging the Z all the way up before doing run from here keeps the Z axis at that height until it completes it's X Y move.

Not specifically Z0 (with plasma, that's top of plate :o ), but a user definable Z height. At present the move to the restart position is done at Safe Z height (whatever that's set to in UCCNC), so if for some reason safe Z was not high enough for this move, a user definable setting in the Preparatory Move popup box would be needed.

There's also a tick box option in the pop up box to do the move to the restart position at rapid speed.

Some safety features require I have seen.

Door Safety to prevent Gcode from running if door is open If cycle has not started teh message teh user IF cycle has started then bring machine to a stop and prevent any more gcode from running. Closing teh door restarts Gcode.

Safety feature to prevent a cycle start IF teh machine has not been RefHomed

A safety feature to prevent UCCNC from running IF teh machine is not powered up and IF you shut down UCCNC then it kills power to teh machine.

Red green yellow light tree functions

Feedhold jog away and return feature

Being able to set SafeZ to user OR machine coords OR to Zhome


Just a thought , (;-) TP

Charge Pump already does this.

Assign the switch to the Feedhold?

Charge pump only does PART of it

Feedhold is not a good function either for door switch.

We have tried it many ways and so far there is always a Glitch as in teh functions are not perfect.

I have tried Plugins, Macroloops and macros.

But we are certainly open for examples (;-)

My charge pump goes to a relay, which handles the safety circuit of a safety relay. If the charge pump drops out, the power gets killed.

And the machine can't be powered up without the charge pump.
