General Mach Discussion / Re: Use of tools in a turret?

Btw, I didnt get anywhere yet :-) You just thought my problems were solved. In reality I chopped thru my cable/internet feed installing my dog's invisible fence (2" under the soil). So I didnt have my computer up and running (plus I was trenching and installing 2000' of cable thru the woods!) I will be back with questions!

Btw I was just trying to get clarification of what the Reset button action would really do.  Home shop safety is a personal issue, though I do think you should do what you can. I got rid of my handwheels and or never used them once I configured my home and limit switches.. Press the "Auto Limits Override" and dont look back.

Jeff, though a great description of what "should" be done and what is acceptable on our hobby machines. One of his questions was, "does pressing the Reset button on the Mach page allow the steppers to freewheel (not locked electrically) on the G540? I have mine reallocated and in a test with a Smoothstepper and nothing is configured correctly or safe during this.

There are 2 different things at play. If you hit the E Stop, all motion should cease. My understanding is that the Reset on Mach should do the same thing. However there is an ability on the G540 to disable the drives (IIRC) but this would involve using a separate switch to disable. I might have always misunderstood the Reset however it stops all motion including the spindle on mine. I dont know if it is doing it thru the contactor or via software though? (my physical E stop kills the contactor)

Dont worry Krugs there are a lot of CAD programs that will do the sort of thing you are trying to do. Learn the ones you have. I personally run BobCad and I do have CamBam though it is different enough in its operation than the BC. I only really have any training on the BC so it is what I understood first. Actually I have Mastercam in 1 of my computers but it too is different. It is just a matter of getting familiar first and then find the shortcomings of that program.

The E Stop should stop all motion and signal possibilities. It will not disable the G540, the steppers should be locked upon E Stop. If I am understanding you correctly, are you expecting the steppers to be able to move by hand when the Gecko is disabled (via the E Stop)?

Connect and use the SCHP (charge pump in the outputs section of Mach) feature. This will disable any output until Mach is operational. It tells the G540 to not do anything until it get this signal. Do you have your Estop enabled and hooked to the correct pin? You dont have a jumper across the E stop input for the original testing do you?

Or just post the screen shot here and be patient, answers usually take a few hours at the most.
