Thanks,

Hello Andy, Hello pl7i92,

I am almost done with this setup, thanks tonns, actually G 38.2 i didnt tried on machine, will try tomorrow with dummy switch.

Apart from that I found one bug, whenever i close EMC with tool in spindle, its not saving existing tool, it shows no tool in next startup. any ideas to avoid this ?


Thanks & Regards,
Ankit

Yes my bad, its not bug its normal... Okay, so all the time when machine starts up we need to remove tool manually and place it in its pocket and then after i can get GCode running.?

Are there any parameters for this ? To overcome this situation ?

Thanks,
Ankit

Yes AndyPugh, i tried unloading with M6T0

But problem with my spindle is, its Alfred Jaeger HF spindle 10000-600000RPM, it cant be left unloaded without tool for longer time, or cant be forced to run without tool loaded into it. Doing so can damage spindle collet mechanism and internals Warned by Manufacturer

So have to think over how to keep tool into it and still manage to change with respective number.

There will always be a free pocket unless you place the tool in the spindle in the rack. Either way you can check to see if there is a free pocket, assuming you have switches that detect a tool in pocket, and if, tool in spindle, then you have the tool thats in the spindle. I do this on every tool change so I know the status of tool-rack and whats in the spindle.

I can do this because I have sensors that detect if there is a tool in the spindle and sensors that detect if there is a tool in each pocket.

I also set selected tool and pocket before updating parameters after I set toolchange flag to true. I dont know if Linuxcnc really needs this because on every tool change, I run the functions to test what I asked for and where the tool is.

Keep in mind doing this you need the tool# to be the same as the tool_pocket always. So you have to govern yourself accordingly when setting up tools and doing your cam stuff.

Regards to all
I was somewhat able to run this example ATC and it works fine, but I have two questions if you can help me,
1. how to do new tool = current tool ignore tool replacement.
2. my machine requires tool orientation
Thanks a lot
