Doing that means I would have to adjust all the locations in my tool change change script and touch off, right? And then I would also have to edit my post because the Z0 moves would be at the soft limit, through the safe zone. I had just test run a few programs before reading this and nothing in the standard g-code in every file causes the machine to go near the soft limits yet I get the warning every time.

Attach your code, your tooltable, offset table and xml and I will see if I can figure it out. Tooltable and Offset will be found in the macro folder then in the folder of your profile, they are called tools3.dat and fixtures.dat

Testing here IF I violate the space then I get the warning IF I stay in the boundaries I do not.

SO can you post an example of a short program that causes you problems? Easy enough to test.


YOU Have the lead on this one Hood. I'll stand by.

Here's the attachments. I tired using the home offsets, see picture attached of the settings I used. It still didn't fix the warning message, the only way I can get rid of the message besides turning soft limits off is move the Z max to say 3, it just doesn't appear to be calculating tool offsets when reading the program before running it.

Forgot to include the g-code in the zip file, but if you look back at my third post in this thread you'll see the .nc file attached.

You have some weird things going on in Ports and Pins, for example you have the Home switches set up to port 1 pins7, 8 and 9. They are OutPuts on Port 1 but maybe you have some other type of hardware that can share pins?

Just a note BUT the gocde has the Z running ABOVE the softlimits zone.

Justa thought, (;-) TP

Ok just found out you are using Industry Control Software with the MCB1 and really you should be getting support from them as your xml wont run on Mach3.
I did load your xml, tool table etc into IC and loading the code didnt give me a softlimit  error but afraid I dont have the MCB1 so cant test things properly.

Thanks, guess I will taking this thread to their forums then. As for the g-code running above soft limits - it does not. It looks that way because with tool and work offsets applied Z0 become the top of the spoil board/bottom of material, so besides the -.005 cut through depth, all the Z moves in the g-code are positive values. When the g-code returns the Z axis to 'home' it uses G53, disregarding the offsets and staying clear of the soft limits.

OH but it does , You are using the the inverse z method where all your moves are positive instead of negative. That is backwards to conventional useage.  You now have 2 homes that move in opposite directions of each other(;-)

 IF you set the Z zero too high off the table OR use a tool offset that moves the Z into the machine  Softlimit zone it will trip.
