Last video around 8 minutes is how I edited the post. there's 3 videos and they all have sound.

I did. Watch the videos.

Still curious what other Milltronics owners that run a 4th axis do with their setup/parameters.

I still haven't checked if the brake is left on and powered down, if the brake will still be on when...

That still doesn't address the ability to jog with the brake on.

end of a simple F360 indexing program leaves the brake on

N2960 M9
N2970 G32
N2980 M11
N2990 G0 A0
N3000 M10
N3010 G28 G91 X0 Y0
N3020 G90
N3030 M30

It does run smoothly but it makes it a pain in the ass to have to MDI M11 to position the rotary axis with handwheel or jog function.

I wonder if there is a way to edit the macro for the jog and...

Maybe I haven't explained my self very well. I'm looking for an uninterrupted cutting motion making a great machine finish that will still need a day or more of hand polishing. Any little divot...

I still question if there's any kind of setting through the Milltronics system that would keep the A axis from turning when the brake is on. Now that I've set the Auto Rotary Brake parameter to NO

Here's the sample program that F360 spit out:

N20 G20

I've had my Main-Parms-CTRL Auto Rotary Brake set to yes since I installed my 4th axis on my RH19 Cent7. After getting my Fusion 360 post processor to spit out code for full 4th axis machining and...

Thanks for the replies. The older I get the more frustrated I get that I was the guy that drove a 442 and not something with a small block Chevy while working at a speed shop that sold SBC go-fast...

sure
It's like learning another language.

pretty sure the milltronics post doesn't have the switch to turn on the 4th.

I've got my fleabay 4th axis working well on my RH19 Cent7. Just looking for a post that runs the 4th axis with F360. It looks like I need to modify my own or find one that's been done correctly. ...

The relays in the machine are not currently produced and I bought an upgraded General Purpose Relay PT3S7LC4. It has the same plug in relay module, but it looks like it has an integrated diode...

Looking to add a coolant pump that the control on my RH19 Cent7 will control. The electrical drawing shows what looks to me like a combo diode/resistor as shown in the red box in the pic. What parts...

changing to 2000 on the drive worked

Sigma 7 vs DMM #?

Mactec54
When you tested the DMM servos for Yaskawa, what model/models did you test?
DYN5?

I was hoping I could use the SigmaWin tune all 4 axis after watching this video from Yaskawa.

I'm sure that surface finishes would benefit form a complete custom...

I changed the 201 parameter from 1000 to 2000 on the SigmaII drive only and this solved the doubling of the programmed feed. Yea!

I do have the manual for the SigmaII but I'm more of an operator...

I'm sure the DMM and Delta servo systems are pretty good, they just don't make a cable that plugs into my Milltronics Interface board and the servo drive. The Yaskawa SigmaII motor listed on the...

right now the tune sounds pretty good by ear. running it on the test bench was quite loud and squealing.

my current problem is rotating twice the value programmed.

a recent email from...

Posted over on the Milltronics section as well.

Well I finally got the 4th axis running. However when I tell it to spin 180 degrees it spins all the way around. Not sure which setting I need to...

Well I finally got the 4th axis running. However when I tell it to spin 180 degrees it spins all the way around. Not sure which setting I need to change.

I recently got my 4th axis motor installed on a used Tanshing VRNC-210 rotary table for my 2006 Milltronics RH-19 with Cent7 control. Now I need to tune the servo setup using Sigmawin+5.75. Not a lot...

I got a hardened gear installed and now need to tune the servo setup using Sigmawin+5.75. Not a lot of info available for the older Sigma II.

Bench test

12L14 cuts so well!

Just a quick video making a sling swivel. Love my mill just wish I had more time to run it.
