Why won't it change the tool?

I ran a simple vcarve program it ended and i loaded the next program which was a profile to cut out the word I had just carved previously. I rewound the profile cut and hit cycle start. The machine went to the tool setter, measured the v bit that was still in the spindle, and then proceeded to go right back to work origin and try to cut a profile with that v bit. I of course stopped it with the estop before it could ruin the work, The program called for a 1/4” inch bit which I had numbered correctly and was in the proper pocket as listed in vectrics and the masso showed that the v bit was currently occupied in the spindle, yet when the program ran it did not eject the vbit and load the 1/4” downbit, why? What am I missing? Elite journeyman with easy atc and tool setter all from onefinity. I have run the tool changer test successfully twice. Something I am missing?

I don’t use the ATC and I’m not sure of its parameters but did you check that you are using the ATC post processor and all vectors are saved to one file?

I had that happen to me three times when I had the ATC. I got rid of it because I already spent so much time and confusion on getting it setup, I sold it and went back to manual tool changes. I was too busy at the time to deal with stuff not working and didn’t want to ruin my projects.

I too have an Elite Journeyman.

I had configured the ATC the “3-wire Subroutine” way and was able to do test swaps of tools. Then a friend of mine came over and I went to show him the toolchanger. Guess what suddenly quit working. I freely admit that it likely quit working because I made some mistake. But I have no idea what that mistake was.

I find the “Subroutine” configuration to be somewhat confusing and didn’t want to go through the work of trying to diagnose it. This I think is specific to how my old geezer brain thinks. I just find the Masso “direct control” method to be easier to understand.

So this last weekend I decided to upgrade my Masso controller to the latest firmware. I then did a lot of head-scratching trying to figure out how to configure all the parameters so that the Masso would directly control the tool changer. It is now working and I have successful tool changes.

Please note that I am NOT suggesting that you must change from the “Subroutine” way to the “Masso controlled” way. I made the switch only because of the way my old brain works and the way I specifically use my CNC.

Pretty much all of my carving that I did this summer involved me writing Python code (I have my own python library that barfs out gcode). This is what makes me partial to the “masso controlled” way. I only need to know “T1 M6”. I don’t have to understand a bunch of 3rd party gcode subroutines.

I have read numerous posts of other people getting reliable tool changes with the “Subroutine” way. It just wasn’t for me.

If you are still having problems with your tool changer, you may want to just log a support call with RapidATC. Again, from what I have read, the head of the company provides fantastic support.

I purchased the 4-tool RapidATC directly from OneFinity. I think it is an awesome addition to my CNC hobby and I look forward to using it.
