Title: change (Linuxcnc step/dir-servos) to Mach3 to suit recipient. Obsolete pcb
Post by: docslip on May 26, 2024, 10:42:43 AM

It seems that my documentation is lost, I'm too old , and Company who made the p.c.b is no longer around, I think because web site domain is for sale.
The p.c.b is a p.w.m input to analog 0-10 volt output.
Web page silk is screened on board says "www.kdntool.com   DCNC/VFD/OPTO REV1".

If someone has a schematic for this p.c.p could you please email it to me?
With thanks,

I'm giving my converted Grip1340 G ball-screw converted lathe to a friend whom I was unable to convert to linuxcnc. He's a Mach lover.

Attached 1 only photo of the obsolete item described.

Is this for a DC servo?  It may be simpler and cheaper to replace the amplifier with a DC servo driver.
