Sorry, Scott ,it took a while to get back had some family issues to deal with in the meantime glad that's over ! Yes i am ,"[The built in encoder works fine ", and i have run several tests and parts of different kinds internal and external threads without a fault. Tried intercon and two di...

To the control, the encoder may be showing the wrong direction. In the wizard, do you have a - sign in front of the encoder count value or no? If yes, take it out, if no, put it in and give another try. Marty That solved the error problem but ,it was still dropping the thread , i have fixed it thou...

After the latest on this problem i decided to hook back up the encoder one more time and check one more time , i get a little message from Acorn, spindle slave position error when trying to cut the thread .

Marty wrote t will have to be from one of you that really wants to use a DMM AC servo for a spindle motor and try and use it's encoder for feed back. I choose to do it the traditional way.when possible. VFD driven spindle with a standard encoder belted 1:1 with a timing belt TO the spindle. Maybe Fr...

The index pulse just starts the thread it is not the only signal that is required to complete the thread as has been discussed here before . I would like to be proven wrong so lets see a video of a DMM tech motor and encoder actually cutting and tapping a thread on a lathe before you scold everyone ...

Marty DMM asked me to post this clip showing their encoder does indeed work with Acorn. So those of you trying to use a DMM motor as a spindle motor with the encoder output to Acorn shouldn't have a problem. It is important that you make up your encoder cable using proper wiring methods which includ...

Drill and tap two holes across from each other 3/8 and use a bar puller , make a plug to go into end of spindle shaft with a center drilled in it ,for the puller screw. If you soaked it it should come off without to much trouble, you can buy split clamp style timing belt pulleys just slip over the s...

Can you please post the solution? This has happened before and will likely happen again. For the life of me, I can't remember what resolved it. This is what i came up with ,use a external encoder tied 1:1 to spindle of lathe , this is the one i used below https://www.automationdirect.com/adc/Shoppi...

WHo ! Who! here stop hijacking my thread for this crap, if you can not be of benefit, take it somewhere else , these are nice folk's and should be treated as such ! :mrgreen: Any way i have mine working and threading just fine , after taking care of the EMI problem and it was not DMM techs fault ,it...
