Acorn Mill Pro - Encoded Spindel & 4th Axis Synchronization

[A.J.]

Dear Acorn creators,

My Emco Compact 6P Acorn conversion gets slowly towards its end and an Emco F1 mill is already waiting.

So I got a question for you:

If the mill spindle would get an encoder would the mill software & Acorn be able to run the spindle synchronous with the 4th axis (or any other) ?

My guess is that it is pretty much what the lathe software and the Acorn are doing during threading and it should be possible - however my confidence level is not at 100%.

Just to make the thought more realisitc: Imagine a gear hobbing process with the hob in the spindle. This would require that the spindle and the 4th axis - which turns the blank part - run synchronous (and yes I know for such a small mill this is an unusual process but it's meant to be for a quite small modulus in the 0.5 mm area).

I am looking forward to your appreciated answer.

Best regards from Germany & stay healthy !

... time to order another Acorn board - but the question is still open before.

The task is very similar to rigid tapping or lathe threading but it would be nice to get a confirmation as I haven worked with the mill software so far.

Thanks in advance.

Currently CNC12 does not support the spindle synchronized with any other axis than Z. Hobbing is on the to-do list.

Thank you Tom.

Hope is no methodology - so I am going to think about a workaround as I like to stay with the Acorn.

I am pretty sure to get step (& direction) signals with the desired ratio to the spindle encoder to the 4th axis motor.

So the 4th axis would get some own electronics & programming.

If the Centroid developers work through the hobbing item first then it's even better.

So I will place another order.

Best regards
