Hi All

Just wondering , has anybody here done a Denford Novamill - Acorn retrofit
I picked up one of these little mills with ATC a while ago and finally have the time to try and get it running.
I already have an acorn board that i am planning to use to replace the original controller but other ...

If you want to stick to what is built into the wizard and the standard template, then of course you are more limited.

Ok , that makes sense
Thank you

From Acorn CNC12 v4.20 Acorn Wizard Input and Output “canned” PLC functions and M codes :

Input for Low Air Alarm, issue message when input is Active, finishes current G code job (does not stop current Job that is running).

works just like low lube….issues warning message, continues to run ...

Hi
Could anyone tell me briefly how the Low air pressure input works on the latest version of CNC12 , i have searched forum threads but can't find anything.
I'm still running the previous CNC12 version but suspect i may need to update to get this feature.

In brief i am running a homebuilt ATC on a ...

Sorry, cant help - I no longer run an ATC on my lathe - but would be interested to know too.


Hi
No problem and thanks for your reply.
With a little head scratching I modified the macro to better suit my application and so far it now works.


Can you please post the updated code? I have a ...

Chris ! Success !

I have to confess i took the easy option and used your compiled PLC attachment ,

Wow that was a fast reply , i've just left the workshop to get some food in me.

The Axis Driven turrets are done by macro, however the software requires plc logic to display the "Tool: t0101". I did a short test quickly u can at the end of the macro write to the parameter of the tool you requested, and then you can edit the PLC to read from that parameter.

Try changing Parameter 160 from 1 to 0.

As far as I am aware, the "Enhanced ATC" functions only apply to certain mill tool changers, and do not apply to the lathe software nor to lathe turrets. But when used, "Enhanced ATC" changes the source of the displayed tool number.



Hi
Thank you for ...
