Beaver Knee mill conversion- by a newbie

[Clive S]

Servos came today. I paid for them on 28 December. That is amazing service. They were sent from china bought from fasttobuy on ebay.
Going to have to make up my mind on the controller soon.

Its the cables I believe that are expensive if you don't get the servo and driver with cables as one unit.

Hey up Clive, I have got the cables with the motors and controllers. The ones with a round plug on one end and D on the other.
Are those the ones you mean?

Just trying to understand the chinglish manual, it's not going to be easy(LOL).

Ah! In post #1 you said you have two AB servos without the drivers

[ukmxer]

Oh yes I have those two but I got no wiring or controllers with them, so they are on the shelf in the workshop. this is a picture of the label.

I bit the bullet and got the CSMIO/IP-M. Now it is time for my journey to begin.
I have no experience in machine building, so I look forward to learning something new.

Could someone please tell me if I put 2500 in as my encoder steps per or 10000(quad) in mach motor tuning.
This is from the manual for my servo :-
The encoder feedback 2500p/r,15 line increment model, differential output
I have it running step/dir through the csmio ip/m . The servo model 90ST-M02430.

will be 10,000 i think - they call it "all edges" so it senses 2500 rising edges plus 2500 falling edges and then the same again on the quadrature output so 10,000

Well yes and no really. Yes your 2500ppr becomes 10,000ppr because it's quadrature encoder so 2500 x 4. But in motor tuning you need to divide 10,000 by the pitch of your ballscrew because your entering steps per MM or Inch into tuning.
So 10'000 pulses per rev which becomes your steps per revolution in mach3 is divided by say 5mm pitch becomes 2000 pulses per MM.
