Centroid Community CNC Support Forum

I recently purchased a used 2021 ATrump AL42 with Centroid Control. It is an Oak. I am having an issue with the tool changer. It is a swing arm changer. Always works great if the carosel indexes at least 2 tools. Trouble happens when the carosel does not need to index and it is simply swaping the spindle tool for the current carosel position. The message box shows "311 Waiting for memory #30 (M100)". Then a couple seconds later, "8241 ATC MOVE Z AXIS TIMEOUT". Then shortly after: " 311 Waiting for memory #31 (M101).

It does this every time I need to do a tool change without needing to index. Any ideas of where I should look? From observation, It seems as if the spindle orient isn't complete when the pot comes down. I noticed when the carosel indexes a couple of time, it spindle orient completes before the pot comes down. This seems like it may have something to do with it, but I am not sure.

Any ideas on where I should focus my next trouble shooting efforts?

There is a loophole in ATCMoveZAxisStage, where it will only proceed if the tool pot is in the up (idle) position.

Since the pot will swing down as soon as the carousel is in position, that causes the pot to be out of the expected position by the time Z axis movement is acknowledged, if the carousel did not have to rotate at all.

That is fixed in the attached update, along with a bunch of other minor fixes that I have made since the Atrump programs branched off ca. 2020.

The attached update also contains the correct message files and M function macros for your PLC program, so you should get, for example, "Waiting for Automatic Tool Change (4)" instead of "311 Waiting for memory #31 (M101)".

You can install the attached update using F7/Utility -> F2/Restore Report.

Problem Fixed....Thank you Marc!
