Hi Mike,

 

I would just add the X plunge in GCode before doing the Rigid Tap operation.  Shouldn't that work for you?  That might delay a bit after the X plunge before the Spindle starts rotating.  Also in the GCode after doing the "Rigid Tap" motion you can add a retract and rapid move in Z back to the starting point. 

 

To eliminate the Rigid Tap "rewind" motion remove the following lines from the C program. 

 

 // retract fully
DoTap(-ZDist, RetractRate, TPI);

and also add the +ZDist as shown below

 

Delay_sec(1.0);
Move(ZAXIS,Z0+ZDist);   // move to where we ended up
while (!CheckDone(ZAXIS)) ;

Let me know how much of this works :}

Tom, I made the adjustments you suggested to the notifytap program, and I could not get it to run the tap sequence. It would position itself in preparation, then just skip over the tap part and move on to the code after. I fiddled around with it and just ended up adding some lines in the c program to do the retract. It seems to work ok. I uploaded the c prog and my XML to my folder. Could you let me know if it is an acceptable way to do the retract? Also, an odd thing happens when using the edit button in Mach. I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn. I am using 3.043.062....because I heard that the lockdown version had problems in Turn. Maybe I should try the lockdown. Any ideas on that?

Hi Mike,   Not sure why mine didn't work.  But anyways yours is good.   I think if you remove the line:   DoTap(-ZDist, RetractRate, TPI);   Then it will do a rapid move back in Z rather than an "unTap" type of move so it will be faster.   I haven't seen that weird self start of Mach3.  Hard to imagine how our Plugin could be doing that.  Please try the lockdown version to see if it persists.   Regards TK   Group: DynoMotion Message: 5472 From: Michael Niksch Date: 7/29/2012 Subject: Re: Mach 3 Spindle struggle Tom, Yours may not have worked because I may have not followed your directions properly.....lol.  It let me know where to look, though. I left the DoTap(-ZDist, RetractRate, TPI); in because I need the spindle axis to return to exactly where it started when doing the multiple passes necessary for the operation and I didn't know how to do it otherwise.  I'm open to suggestions, though. :-) I didn't think to try running a regular program without plugin calls to see if it would do the self start.  I'll try that first to maybe narrow down things a bit.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating.

I will give it a try tomorrow. As far as the two techniques are concerned....I would look for whatever is the most accurate. I didn't realize there was a choice. Is it a pain to do the second technique? The owner of this shop makes ballscrews and very high precision shafts that are checked by cmm. The idea was to make this machine dedicated for thread grinding carbide. The one thing that is in our favor is that the spindle moves very slow when thread grinding. Like 1 rpm or less....so I think everything will have an easier time tracking at the slow speeds. Even the multi start threads seldom have a pitch over 5mm. The machine has proven itself mechanically capable of maintaining .00005" in standard cylindrical grinding.....so as much accuracy that can be afforded electronically would be ideal. Again.....the thing moves really slow. Tell me what you think.

It seems to work ok. I uploaded the c prog and my XML to my folder.

I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn. I am using 3.043.062....because I heard that the lockdown version had problems in Turn.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating.

It seems to work ok. I uploaded the c prog and my XML to my folder.

I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating.

I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn. I am using 3.043.062....because I heard that the lockdown version had problems in Turn.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating.

Regarding the two slaving techniques: slaving to actual Spindle position is probably the best.  If there is no Spindle positioning error then it doesn't matter both techniques will be the same.  Your requirements are very tight.  To do a 5mm pitch thread with 1um accuracy the spindle position must be known to 1/5000th of a rev! When slaving Z to actual Spindle Position the accuracy of the spindle servo theoretically doesn't matter because the Z axis will track how it actually moves.  However if the measured Spindle position is noisy, for example dithers +/- several counts due to vibration, then having the Z Servo attempt to track that may cause more harm than good.  In such a case it may be better to just have the Z axis follow the perfectly accurate and smooth Spindle trajectory instead. It is easy to switch between modes.  Change the line:     MoveExp(ZAXIS,(chan[SPINDLE_AXIS].Dest-S0)*SlaveGain+Z0, TAU);    to:     MoveExp(ZAXIS,(chan[SPINDLE_AXIS].Position-S0)*SlaveGain+Z0, TAU); Regards TK Group: DynoMotion Message: 5489 From: michaelthomasn Date: 7/31/2012 Subject: Re: Mach 3 Spindle struggle Tom, It does stop now.....but only for a second before it moves to the x retract.

It seems to work ok. I uploaded the c prog and my XML to my folder.

I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn. I am using 3.043.062....because I heard that the lockdown version had problems in Turn.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating.

I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn. I am using 3.043.062....because I heard that the lockdown version had problems in Turn.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating. Also in the GCode after doing the "Rigid Tap" motion you can add a retract and rapid move in Z back to the starting point. > > > > > > > > > > > > > > > > > > > > > > To eliminate the Rigid Tap "rewind" motion remove the following lines from the C program. > > > > > > > > > > > > > > > > > > > > > > // retract fully > > > > > > > > > > > DoTap(-ZDist, RetractRate, TPI); > > > > > > > > > > > and also add the +ZDist as shown below > > > > > > > > > > > > > > > > > > > > > > Delay_sec(1.0); > > > > > > > > > > > Move(ZAXIS,Z0+ZDist); // move to where we ended up > > > > > > > > > > > while (!CheckDone(ZAXIS)) ; > > > > > > > > > > > Let me know how much of this works :} > > > > > > > > > > > > > > > > > > > > > > TK > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > From: michaelthomasn <michaelniksch@> > > > > > > > > > > > To: mailto:DynoMotion%40yahoogroups.com > > > > > > > > > > > Sent: Friday, July 27, 2012 1:35 PM > > > > > > > > > > > Subject: [DynoMotion] Re: Mach 3 Spindle struggle > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > Tom, > > > > > > > > > > > > > > > > > > > > > > I mean I did not set up the spindle as a motor output in Mach. > > > > > > > > > > > > > > > > > > > > > > I copied over the rigid tapping script and put the proper c program into the plugin and had it rigid tapping in air on the grinder.

It seems to work ok. I uploaded the c prog and my XML to my folder. Could you let me know if it is an acceptable way to do the retract? > > > > > > > > > > > > > > > > > > > > Also, an odd thing happens when using the edit button in Mach. I press the button, and it brings up the txt file. I make my adjustment, save it, and when I close the file the program immediately runs in mach without my consent. If I hit the emergency stop, the program stops.....but when I re-initialize it will start again where it was when I hit the E-stop. I wonder if this is just some weird anomaly in MachTurn. I am using 3.043.062....because I heard that the lockdown version had problems in Turn.

Shouldn't that work for you? That might delay a bit after the X plunge before the Spindle starts rotating. Also in the GCode after doing the "Rigid Tap" motion you can add a retract and rapid move in Z back to the starting point. > > > > > > > > > > > > > > > > > > > > > > > > To eliminate the Rigid Tap "rewind" motion remove the following lines from the C program. > > > > > > > > > > > > > > > > > > > > > > > > // retract fully > > > > > > > > > > > > DoTap(-ZDist, RetractRate, TPI); > > > > > > > > > > > > and also add the +ZDist as shown below > > > > > > > > > > > > > > > > > > > > > > > > Delay_sec(1.0); > > > > > > > > > > > > Move(ZAXIS,Z0+ZDist); // move to where we ended up > > > > > > > > > > > > while (!CheckDone(ZAXIS)) ; > > > > > > > > > > > > Let me know how much of this works :} > > > > > > > > > > > > > > > > > > > > > > > > TK > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > From: michaelthomasn <michaelniksch@> > > > > > > > > > > > > To: mailto:DynoMotion%40yahoogroups.com > > > > > > > > > > > > Sent: Friday, July 27, 2012 1:35 PM > > > > > > > > > > > > Subject: [DynoMotion] Re: Mach 3 Spindle struggle > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > Tom, > > > > > > > > > > > > > > > > > > > > > > > > I mean I did not set up the spindle as a motor output in Mach. > > > > > > > > > > > > > > > > > > > > > > > > I copied over the rigid tapping script and put the proper c program into the plugin and had it rigid tapping in air on the grinder.
