The original drives were included inside the SRC320 robot controller sold by Seiko. They were open packaged and may or may not be Yaskawa drives without the plastic case around them. It would cost me...

All four motor encoders are 2048 P/R incremental encoders. The encoder model is a Yaskawa TRD-Y2048.
The motor models vary by size but the catalog coding is consistent with incremental encoders. ...
Which US digital encoder did you use? How are you handling motor commutation?
Hi All,
I bought an old (ca 1999) Seiko SCARA robot just to mess around with as a hobby, It was very inexpensive but didn't come with a controller. I have a lot of servo equipment to play around...
That's awesome! What was the final price? Do they make more? What was your experience with reaching out to them with a brand new design?
I disagree that customization is more limited with Mach 4. Both Mach 3 and Mach 4 come with scripting languages. Mach 3 used VB scripting and Mach 4 uses LUA scripting. Having used both extensively...

Here is a drawing for an AXA that I found using 0.250" wires.
Don't hold me accountable for the content, just did a dew minutes of research.
Dovetail angle is 60 degrees
Unsure...
Maybe it wouldn't work perfectly out of the box, but with a simple modification it could work. I'm thinking of a 3/16" thick steel disk with a 3/4" clearance hole in the center and two counter sunk...
I am currently running Mach 4 with Allen Bradley Ultra 3000 AC servo drives. This is open loop from the perspective of the control, but closed loop at the motor. I am curious (educational use only)...
What a steal. Nice job :)
Not cheap: Aloris 5-C Collet Holder - AXA-5C - Penn Tool Co., Inc
Lots on ebay for ~$150. Some have lever closers
For those who have CNC mills running TTS tooling, we often have many tools preset in holders and loaded in the tool tables of our machines. It would be really nice to clamp a tool in the toolpost for...
I have the same investment in TTS and this is an AWESOME idea. Thinking of a quarter turn lever clamp on the back to clamp/unclamp the tool. It wouldn't need to be R8 necessarily. Maybe you could...
Why not use a chunk of cast iron? It is relatively easy to machine (although dirty) and would be better for rigidity and vibration damping than either Steel or Aluminum. You can buy cast stock from...
I did the goofy thing which was to rebuild an import :). Well it was mostly a teardown and clean. If your hobby isn't machine rebuilding or staring at old american iron then an import will do you...
Enclosure looks great! Nice work, very professional.
Just saw this build and I have to say excellent work! I have a fully converted G0704 which I got my Freshman year of college. Looking back I wish I had gotten a bigger machine :) Congrats
What a stunningly clean conversion. Beautiful work. Would also love to see the electronics enclosure.
I own a Grizzly mill which required a surface cleaning to remove the cosmoline packing grease, but other than that I ran it right out of the box without any issues. I don't own one of their lathes so...
I would seriously recommend getting a little more lathe than you think you'll be able to use at this time. I have bought from grizzly and found their stuff perfectly fine to use out of the box. Some...
I wish :) It would be a heck of a lot more rigid than it is.
Pat, you might have your jogging mode set to incremental. If you press tab in Mach 3 it should bring up the jogging console. Look if the continuous jog is lit up, or if it is set to incremental. Also...
Isn't that the truth. My first build was 10 years ago and it was hard to find parts and information even then. It is amazing how much this hobby blew up.
On my benchtop CNC (G0704) running AC servos, I have my velocity set to 1000 ipm and my accelerations set to 400 in/s/s (1G). It really punches when making rapid moves, but the cutting is so much...
My benchtop with AC servos hits 1000ipm with some crazy accelerations no problem. Since I do mostly 1 offs (really never more than 10), my Rapid override is always set to 5%. Seems kinda silly :)
You may find it a little difficult to find high frequency output VFDs. By US export law, most VFDs and motor drives are limited to 590Hz output frequency in order to prevent the proliferation of...
Did a bunch of deep bearing bores similar to what you're talking about here. Dial in the starting diameter to be very consistent then your finish pass will have the same deflection from part to part....
Ouch! $20 per cutting edge. Bet it works well though. Thanks for the links guys.
Quinn,
If you can find an aluminum specific grooving/parting insert, please let me know. I've never been able to source one. As the width of the insert increases, the strength and stability of...
So I've totally dropped the ball on updating this (I still want to get it finished up). If you want the full thing, it is posted on Hobby Machinist under the same title.
I was offed by having to...
