FAQs / Re: CNC router tries to go beyond axis limits

« on: March 23, 2015, 01:39:21 PM »

The documentation you suggested turned out to be a reference (at least the one I have).  I consulted tutorial videos, but found them to be of no help.  I am unable to get the soft limits button to turn green.

I find the Mach3 interface to be pretty non-intuitive.  (It may have evolved since the version I have, I don't know.)

FYI.

Thanks Overloaded.  I will check out the documentation as you suggest.  I have since also become informed of a the tutorial video #3 (Offsets, Homing - Limits) and am viewing that.  (Unfortunately, I am currently not next to the physical machine and really looking forward to going to the shop tomorrow morning!)

Which leads me to a related question - is there a software simulator that would show how a hypothetical machine would react based on command inputs to a Mach3 installation?

Thanks again.

Like your Lincoln quote - teach fishing vs provide fish.

Correction: When I move along an axis using the arrow keys, and the stepper motor hits the end of the AXIS, the motor does not sense that it has reached the end of the axis and still tries to move past the end.

FAQs / CNC router tries to go beyond axis limits

« on: March 16, 2015, 12:41:58 PM »

Disclaimer - I am a newbie to Mach3 (although I know G-code programming). 

I have inherited a table-top style CNC router, with a cutting area of 300 mm by 500 mm and a 1 HP spindle.  It is considered a "mini" system by the vendor (Eurocnc).

When I move along an axis using the arrow keys, and the stepper motor hits the end of the spindle, the motor does not sense that it has reached the end of the axis and still tries to move past the end.  The result is a horrible sound and vibration, indicating that the motor is being forced to do something that it should not be doing.

Is this normal, or can I prevent this through calibration so that the software is aware of the limits of the axis?

Thanks so much.

PS: My Mach3 installation is V2.63.
