Beaver Knee mill conversion- by a newbie

[ukmxer]

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.

[ukmxer]

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

[m_c]

I've never heard it called edges before, it's normally counts, and for quadrature encoders, it's always four times the slots/lines.

However I have seen various terms used, so if you're unsure, just try the lower figure. Worst case scenario, things only move a quarter what you expect.

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.

Just a minor correction, 2500ppr becomes 10'000Cpr.
Although they're often mixed up anyway, pulse per rev generally refers to the number of pulses each channel produces per rev, which is usually the same as the number of lines, whereas the counts per rev refers to the total number of changes detectable by an encoder counter/reader, which in the case of quadrature encoder is four times the pulses/lines.
