I just started in the world of CNC and am having an issue with my Soft Limits in Mach3 set up. I've read a bunch, watched videos, and search other people's issues, but have yet to find anything to resolve my specific problem. I'm sure it's something simple, but I just can't figure it out, so I'm hoping someone can point me in the right directions.

I'm not sure if any of this matters, but the following are my hardware specs:

• CNC: Zen Toolworks 12x12
• Computer: HP DV9000 Laptop, 2GHz, 2GB, Windows 7, 64-Bit
• Communication Interface: Ethernet via MachForWin64
• Software: Mach3
• Three homing switches: X-, Y-, Z+ (wired individually)
• Three limit switches: X+, Y+, Z- (wired in parallel with E-stop button)

I have sucessfully set up my home switches and am able to 'Reference All Home' with no issues. Also, my limit switches work correctly in that they E-stop the software. It appears that I have set up my Soft Limits set correctly but they won't stop the travel. The reason I say that they appear to be set up correctly is that if I drive any of the axis past its soft limit and then turn off the 'Soft Limits' switch, I am unable to turn it back on until I travel back below the limit -- instead, I get the "Machine out of limits for SoftLimit Activation" message.

So, why does it let me travel past the soft limit setting even though it obviously knows what the limit is?

I suspect that the MachforWin64 controller doesn't support softlimits? I just saw this post after searching for other issues with this controller.
