Re: Acorn suitability for small 4 axis lathe.



I'm confused, page 192 of the CNC12 manual indicates that the M51 command to enable C-Axis is a feature.

It is. You can assign an axis to be a C axis ...

Re: Acorn suitability for small 4 axis lathe.

Marty, if I may, one more question...
On the Centroid website is reference to a C axis lathe - an ATRUMP machine, indicating Centroid's implementation of a Servo driven spindle/C axis setup.

However, the article is a little short on detail - What controller/CNC hardware and software is used and ...

Marty , Thanks for the answer! Not really what I wanted to hear, but at least I know not to pursue the Acorn route.
Thank You.

Re: Acorn suitability for small 4 axis lathe.


You are in the right place to get answers from Centroid, but it IS a holiday weekend, and a long weekend for most.


Hi - Yes, I realise that - the intention was not to whine and whinge! - Sorry if it appears that way! I am new to this forum and not sure how it works - sort of used to asking ...

Re: Acorn suitability for small 4 axis lathe.

You are asking for a lot really.
You want POSITIONAL Accuracy and you want the same servo to act as a spindle motor.
You would need a drive that can take 0-10VDC input or PWM input (Version 4.6 will be able to control a spindle drive with PWM) and have reasonably accurate spindle control ...

Re: Acorn suitability for small 4 axis lathe.

Its not a stepper per se; it is driven by step/dir signals, but it is a CLOSED LOOP AC, brushless servo - with internal drive electronics and 32000 count encoder - it is fully programmable, auto-tune PID loop control software runs to tune it in situ, etc. It makes a perfect spindle motor.

How or ...

Re: Acorn suitability for small 4 axis lathe.

Thanks for your response. Since I already have all the Clearpath servo's (step/dir inputs) - I need the controller to be able to do step and dir axis control which if I am correct, precludes the use of the Allin1 and OAK controllers?
The Clearpath motors are really good, and not 'inexpensive', so ...

Acorn suitability for small 4 axis lathe.

Good day,
I have spent some time digging through MANY forum posts but I think the best way to understand is to ask the questions...
I am making a small high speed CNC lathe. It is progressing well and I am looking at CNC controllers that can do the following:
Normal X/Y axis control X and Y are ...
