BACK to business. I got my motors tuned where they're holding steady,but can't get them to move yet.
I've got the pin # 2-3 for X  4-5 for Y  , but according to my step and direction they should be 3-2. and 5-4. I tried both ways
but no luck yet.
Not sure what you are meaning, cant have both, its either 2-3 or 3-2 . Actually now I know you are related to Brett I suppose anything is possible.

I've got a couple mpgs I took off some other machines that have 8 wires. Marked 6 volts, but the machines didn't have 6 volts. only 5v 12v and 24.
Anyone familiar with these? Came off Allen Bradley Bandit control.

Ed

They will likely be 5v but not sure if they will be what you are looking for as I wouldnt expect any more than 6wires on a differential encoder so 8 wires is making me think its not a normal square wave encoder. Got any part numbers?

Hood, Brother Brett, and all other relatives, ;)

   Enclosed pics of Excello model  602 machine I'm working on.It's one of a few verticles of this size
that has a full 6" travel on Z axis./ with #40 taper. My big Yamazen has only 5".

  The other pics are the mpg which was used with the servos I'm using. 8 wires.any knowledge about this mpg  ?

I have the X and Y motors tuned and stable. no oscilation, and cannot turn by hand with power on. On ports and pins
I put in X-pin 2-3. Ypin 3-4. No movement. I then reversed pin # to X 3-2  Y 4-3. still no movement.
Read thru Gecko instructions 20 times, and still is Greek to me. Wish they had one in English for dummies. :D

Step 5 reads
"Set the STEP pulse generator to about 40 pulses per second and set the DIRECTION output to clockwise (logical “1”)."
Wheres the Step pulse generator?? ???

Thanks all

Step Gen is on Diagnostics page in Mach.
The mill  I am doing at the moment has Z travel 6inch, 40 taper, quill Dia 4 inch ,  X travel 32 inch , Y travel 16 inch , knee 17inch.
Cant find any info on your encoder yet, will keep searching and let you know if I find anything. Only reason I can see for 8 wires is it has an Index pulse but why it would have that on a handwheel I dont know :(

Hood, Brother Brett, and all other relatives,
;D

I've never seen a hand wheel like that either Ed. New ones can be found cheap. Have a look at CNC4PC and Homan designs web sites. I wonder what is under the board on that one. All you need is a +V, ground, A and B channels.

I have a funny feeling it may not be a TTL encoder and that is what the ciruit is for to turn it into ttl. How many wires connect to the 9 pin D?
