I have aquired a old cnc pick and place unit witch I intend to convert to 3D cnc / mill ?
BUT it uses 2 sevo motors with encoders for one axis one on each side Attachment 248076
Can I set up the artsoft to use two motors and encoders on one axis ?
any advise thanks John

I think you are confusing artcam with mach3 (artsoft?)

It can use 2 motors for 1 axis, I don't know if it will read the encoders or not.

Look at Kflop and Kanalog if analog servo's.

Thanks for info will look into it ?

If the servo drives that the machine has take step/dir then you can use Mach3, find out what Servo Drives/motors you have,also if the Encoders goes to the Servo Drive or to the control, this will tell us what you need to do

will strip out and check but also has sony linear encoder/scales on all axis could this be used as well for feedback ? thanks john

Just slave the one motor off the other, the encoder is just feedback to keep the co-ordinates absolute,

Ok have issue with servo drivers cannot get information on inputs or how to use as is proprietary for the machine maker and the manufacture will not give any details out?

So considering replacing servos with steppers as servo drivers too expensive for 3 off

Can anyone advise if the torque of 13 kg-cm on the servo motor would be measured the same way on a stepper motor or different?

E.g. the servo is the max torque before stall and the stepper max holding torque as trying to find equivalent power!
Thanks john

[Wombilly]

what is the make of the servo drivers?

[wildrat]

Motors marked TS4047N116E31
Drivers marked AU6310N2031
All Tamagawa-Seiki
Fitted to a Juki KE-710 pick and place unit ?

Thanks john
