Title: ATC with Mach3
Post by: Roberto on May 03, 2017, 01:15:32 PM

I have a problem with automatic tool change.  If I change lets say to tool 2 the screen shows tool 2, but it has the wrong x,z values. But if I then go to tool number on the screen and hit tool 2 and enter it, it changes to the right x,z values.  So on running a program with tool changes, the tool change occurs and it shows the correct number on the screen, but it is not the correct x,z values,  Mach 3 does not seem to recognize the tool change unless I manually reenter the tool number, which makes it impossible to run a program with tool changes.

Any help out there??

Never mind!  I figured out what I was doing wrong.  When entering a tool number you must put in the tool number and the offset for the tool .  For example T0101 means tool 1 and the offset for tool one,
T0303 means tool number 3 and the offset for tool number3.  I was going astray by putting in T0101 and then T0301,  so I was switching to tool 3 but was using the offset for tool 1.  I mistakenly  thought all the offsets were in reference to tool 1 so I was using 1 for all the offset numbers.  Dumb and dumber!!

Hi, I'm fairly new to CNC milling. I have a CNC Linear machine with an ATC using Mach 3 as the controller. I would like to be able to disable the ATC and manually run a milling routine starting from the home position 0,0. I'm not sure which settings to change in Mach 3 in order to do this. Any help would be immensely appreciated.

Hi,
on the Config/General Config... page top left hand corner there are settings for tool change. If you wish just to continue with the tool
currently fitted check the 'Ignore Tool Change' option. I think it would pay to restart Mach just in case a restart is required for the
setting to be recognised.

Thanks for the direction to go. Now is there any special settings to change in order to start the current milling operation from location 0,0 ?

Duh....ignore the last post. It occurred to me that I can just home the machine and start the milling operation like normal. The only thing changing is the ATC will be ignored. Thanks, Craig.
