    Re: Mach3/ESS/Yaskawa servo - under construction

    Found this thread today and was quite excited to see someone actually was able to use Yaskawa drives. I have a pair of SGMJV motors and SGDV 1R6A11A drives but in reading I believe you used a model...

    Thanks MSB. I may have to back peddle a bit on this project. I was thinking my drives would handle pulse/direction but turns out they only understand MECHATROLINK (a form of serial that few servo...
  4. Re: Thinking of doing a lathe build and need some basic questions answered.

    it's starting to look like the Smooth Step might be the ticket where the work is done for you. I tend to prefer more in depth details so I can better understand capabilities. The Yaskawa Sigma V says...
  5. Thinking of doing a lathe build and need some basic questions answered.

    It's a bit confusing trying to figure out what Mach4 will and won't do. My goal is to control the new lathe well enough that it can thread accurately granting any physical stability will play into...

    Re: carving a statue

    I was really happy to find RoboDK Marv, I have had this bot for almost ten years and only the teach pendant to make it do squat. The pendant is fine if you have ONE job to do 100k times but for one...

    carving a statue

    Imagine the statue of David. The z axis runs from head to toe and the work (feet) are mounted to a rotary axis of a multi axis machine. The statue is rendered in .stl format. It's pretty easy for me...
