Title: Lathe G83/M1083
Post by: Sparky_NY on March 28, 2012, 06:11:28 PM
Been experimenting and reading up on lathe G83 and G83.1 peck cycle. I believe
it was changed a few years back to also support G83.1 using a parameter C in the
command.

These two lines behave exactly the same, why? C should change things
according to the note in the M1083 macro file. (further down in the M1083 file
it refers to C as "taper" which is confusing!!!)

G83 X0 Z-1.0 Q.15 R.2 C0 F.002
G83 X0 Z-1.0 Q.15 R.2 C1 F.002

both enter at the commanded feedrate (.002) all the way in and retract fully
each peck. If I read it right, that is what the C parameter should change.

I would like to either not retract fully each peck OR after a full retract,
rapid in to just above the last peck depth.

Doing it the way it works now gets it done BUT is slow as hell.

Hopefully someone can steer me in the right direction.   
Thanks,
George

For peck drilling on the lathe I have used what is in the link and worked great.

I have seen various macro's people wrote as a work-around including the ones you linked.    I researched the G83.1 history and it was fixed and working back around 2005 but has quit sometime thereafter.    I have been working the last few days with Brian and can report that G83 and G83.1 now are fixed and working with the standard m1083 macro.   

It will probably take a little time for these changes to be released in the development version BUT they are on their way and do work.   Other things have been fixed in lathe recently also and yet other things are being worked on.    Mach lathe is a much better product than it was just a couple weeks ago.

Not aware of what's happening. Maybe you can enlighten us.

Brian has fixed some of the long standing lathe issues.   All is not done yet but much is.   Softlimits now work, toolpath display had some bugs fixed, G53 has been fixed, some tweaks to tool offsets and some other things that don't come right to mind.   Suffice it to say mach lathe is getting some needed attention.

The fixes I mention are in progress, some complete some almost done.  They are not in the development version yet,  except softlimits, that is in the current version.

I am tickled.
