The G53 puts it in machine co-ordinates so I can send the carriage to the tool change position without doing an M6. 

I have tried LazyCam and LazyTurn 6 or 7 times and have never been able to get any code out of them.  I am pretty good at AutoCAD and can draw up a part in just a few minutes.  I would love to use that programs if I could ever get them to work.  See my most recent post to the LazyTurn forum.

Vince,
The programs work, it's just another learning curve. Go to members docs and look thru the LazyCam Turn
manual. It's not the best, but it should shorten the learning curve. I am not going to update it since
LazyTurn is going to replace lazycam turn. It's the only writtten info that you will find.

Here is the DXF file for the Crosshead Guide that I spent 3 hours hand coding.  It took me literally 5 minutes to draw in AutoCAD.

Just load up this file and see what you get, it works fine on my set-up R3.043.00

Below is what I got when I loaded your program into version 3.042.008.  I have not tried to load version 3.043 because I am a little gun shy from my last attempt to upgrade to the lockdown version .020 what killed my VB script.  What program/s did you use to produce the code?

Vince

Ok, that is just a setting in Mach3 that is making it look like that. My setup is like this :-

Graham

Graham, my setting are exactly the same as yours.  It must be version 3.043.  Well, I missed the reversed arcs in front.  Thanks for the post.

Vince

Vince,
Check ...reversed arc's in front post.... in turn options tab.
Anytime you get those stupid crop circles that's what you need to do.

Thanks Rich, that was it.  I'm glad I can keep my current version on my lathe.  It seems every time I change I get bugs that I have to figure out.  I installed V3.043 on my mill and now I get watchdog triggers several times a program. 

Graham, I'm curious about the program to that generated the code.  The feed rate is .0039 which would take about 2 weeks to cut at that rate.  Looking over the code there is no tool I could use to cut it.   I was planning on using a 1/8" grooving tool.  I changed the DXF so code generated from it should work.  I extended the section at the front of the part by 1/8" so that the front side of the tool will end up making the proper rounded corner.

Vince

Hi Vince,

what feed, speed, depth of cut & finishing allowance do you want and I will do you some code using your .125 tool, is it a ball end or a square end ?.
