Some questions about Mach3
« on: March 19, 2013, 10:11:22 PM »
I am building a multi-purpose machine and I have some questions about how Mach3 operates which will influence how I wire it.  I have two milling/lathe spindles that are interchangeble.  Once is DC motor driven, the other is stepper motor driven, and therefore positionable.  I also have another stepper motor which is to be used for an extruder for 3D printing. I have a USB 4 axis breakout board.  I intend on driving the stepper spindle and the extruder from seperate drives, but using the same step, enable, and direction signals, which are switched by a multipole relay.

My questions:
What powers up the stepper drives?  Just enabling the E-stop circuit, or is there a standby mode where you can be programming and such but the drives are off?

I want to use the machine as a Vertical Mill, Horizontal Mill, Vertical Lathe, Horizontal Lathe, Shaper, Cutoff Saw, 4 axis robot with pneumatic gripper, and 3D printer.  The vertical mill and the horizontal mill need to switch the Y and a Z axis.  The lathe axis get switched around too.  When I want to 3D print the A Axis signals need to go to the extruder etc.  Is the best way to do this to create a profile for each machine type?

Thanks,

Gary H. Lucas

He Gary, welcome to the forum!  That will be what we call a humm dinger.  :)

Depends on your drives and how you wire them up.  Your break out board can have some bearing on this as well.

That would be a good way to go I think.

;D If you could see the things I have in my head, you would be laughing too. ;D
