Hood,
  Perhaps I should have said "as good as needed for hobby aplication".Obviously there are
far better drives, I just think for the average user the simplicity of gecko's is hard to beat.

Gecko 320 / 340 are as good as you can get. wiring is a doddle wire them common +5volt.
If you can wire a stepper system then there will be nothing here to worry you.
  I would say use 340's with encoders 500 counts (quad 2000) and you will be safe using 2x multiplier.
dont use 5x or 10x unless you are using them on a point to point system.
  Ie a drilling machine or pick and place.
Ive built a few systems using them and have never had a problem.

« on: January 12, 2008, 02:47:36 PM »
Guys,
  just bought a large turretmill (5hp) that is equiped with an anilam 1100m controll
and servo,s. its a 1996 machine.
  althought the anilam works perfectly and the drives are good ect, I am used to using mach3
so I would like to link mach3 to the drives and remove the anilam controll do I need those pixies?
  Any advice positive or negative would be appreciated.

Clive,
   I have read back through your posts,have you definatly got a pulse signal going from your
breakout board to your driver when you Jog? I usually just attach a small speaker/earphone to the step wire and it
will buzz at differant pitches for differant feed rates,and should be clear and un stutterng.
If you have the buzz and the enable system is disconnected then the motors should turn.
  Do the motors do do anything? I know you say they are energised which is as it should be at stand still with the
enable system disconnected.Do the motors make any noise when commanded to move?
   I have had no expieriance with the cpc4pc system  but they are all very similar.
Whereabouts are you prehaps one of our local forum members can visit you to help.

Hood,
  I doubt it as the case is plastic.
I'll strip one tommorow and see if I can get some photos.

Hood,
  Thanks for taking time.
 yes I found that link before,but I was intending on striping them and modifying them.
or probably using them as mpg encoders.They were cheap enough!

off ebay:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150177860536

there are only three wires coming from them,does anyone know how to wire them for
quadralature? I have tried getting info from the vendor but they appear to be
ignoring my emails!
