General Mach Discussion / Re: Mach3Turn Offsets?
« on: October 28, 2014, 05:56:01 AM »
Well,I ran some of the old code output by V10 and it used your unmodified PP that you gave me earlier in this thread.

The spindle acts exactly as it should in that file. It regulates to initial speed and then continues steadily during that operation. Changes to the next called speed on the next op. This is as it should be.

V13 is definitely doing something different.
I thought it might had been a Mach 3 settings somewhere, but nope.

I will compare texts files and see what the difference actually is. I'll then post the results here.

Thanks, Hood.
Definitely something still going on with it. I'll investigate further and let you know if I get it sorted out. :)

Right. I was thinking rigid tapping. Not having done threading on a cnc lathe, I confused myself with it. ;)

Spindle keeps turning the same direction for use with a threading tool.

I will try to do a CAM part that maintains one speed throughout and see how the spindle reacts.
It is still stopping and starting, but never gets a chance to stop completely.
The Check box for CSS in not lit in Mach 3, but it does flash numbers beside it when it's running and those do change.
Honestly I have never really noticed those before. :(

I did buy the spindle encoder that uses a hole in a disk, but never installed it. It is partially a trust issue I think. I think I would trust a servo setup more and it would be more precise than the motor I have on it now.
It doesn't have any braking on it.
I am currently running the steppers off of Gecko 203V's. 72 VDC 12 Amp PS. The lathe is only 110 VAC right now, but it sits close to the circuit panel and I could runn 220 to it as well to run a spindle from. My question now is if I did use a 220 VAC and chose AC servo's, could it use the same BOB as the DC steppers? Right now, the motor controls are inside the control panel on the larthe.

There is a need now to find an answer before my little motors quits completely, but I haven't decided to go with servo's yet. I was unable to locate brushes for my old mill motor, but I may be able to find them for this one. That would give me more time. :)

That was my conclusion as well. It may be noise in the motor controller. I don't normally run the lathe. My Son and his Wife does. They probably would not realize the spindle is acting differently.

I am considering putting a servo motor on it instead of the DC motor that is on there now.
Much better control of the spindle speed that way as well as direction then. It could finally be able to do some threading.
I used to take care of threading with a little 7/14 manual lathe. That motor control burnt out, so it isn't running.
I think I would much rather do cnc threads instead. ;)

Judging from the time it took my mill to burn through the brushes on it's old DC motor (similar) then this one is getting close to needing replacements sourced anyway.
I had always intended to do threading eventually, so it is about that time.

Servo's are relatively new to me so I'll have to research them a bit. Any recommendations? :)

General Mach Discussion / Re: Mach3Turn Offsets?
« on: October 24, 2014, 03:04:06 PM »
That is all there is in there now as well.
Now the code wants to fluctuate the spindle rather than stop it. Kind of like it is wanting to do constant surface speed rather than set spindle speed. That isn't as bad. It shouldn't be doing that either though. I'll look closer at it when I get a chance. Gotta get some parts turned out first. :)
Thanks Hood.
That new 3D simulation in Dolphin is pretty cool. Check it out if you haven't seen it yet.
There are a few videos on Youtube in the Dolphin channel.

Here is the Version 13 of the last post that you gave me, Hood.
I had to send it in and they updated it for me. Works great now.



Everything seems to be working okay in simulation. 2D sim that is. I still have a glitch in 3D sim, but they are working on that.

I'll let you know how the lathe runs.
I did do a compare on the two text files of the Posts. They only changed a few things, but those were important things. :)

Lets hold the phone, which is what I should have done before. They did leave me a voicemail yesterday.
I called them up and everything is okay now. :)
Maybe not with the posts, but I will post my results here.
I did decide to update to the latest version. There was a problem with the version 10, but I decided to eliminate that problem with the authentication process. Version 11 forward no longer uses a third party to authenticate the software. An email or phone call is all that is needed from V11 forward.
I'll let you guys know how it works out. Thanks a bunch, Hood.

Just regular old Mach 3 Turn with the Blue screen set. It is an Lset. The only thing that has changed was this PP recently from the last PP that you gave me.
No I did not modify it in Notepad like I should have, but used the PP Utility provided by Dolphin.

That may be where I messed up.

On a side note, Dolphin has not answered my quote request. Each time you install a Demo, it over wrote my original version 10 or the last Demo. Tried re installing V10 and now my activation code is too old and it will not let me verify the installation unless I contact Dolphin and beg them for a reset.
Well, if they aren't interested in selling me a new version, how long will it take for them to do something with software they sold 7 years ago?
I understand the need for such security, but why does new Demo software over write my old verified software.
All these issues will help me determine what I end up getting. ;)

Thanks Hood.
