To many retracts!

[ujmujm]

When I right a contour program with multiple depth of cuts and check keep tool down, when I post it out the tool retracts to the home position for every cut, is there something in the  control definition, machine definition or configuration that might have been enabled by mistake? when I back plot it the tool stays down.

Any help would be appreciated thanks

What do you mean by "retracts to the home position"?  Does it retract to the clearance plane, retract plane, or does it actually send your machine home in Z?

G0 G53 Z0.  for every depth of cut or multi pass it all of sudden started doing it, I deleted the tool path and wrote a new one and it does the same thing and what's weird is there are operations in my program that are unaffected.

If you create a new file does it continue to do the same thing? 

Can you post your file (or something similar) here for someone to look at?

[gcode]

what kind of post are you using?

Some posts use  misc intergers to control this behavior

[ajmer]

Check your misc values

1 of them is making it retract between passes

[Colin Gilchrist]

Check your "Misc Values". It is either 'mi7$' or 'mi8$' that controls the "retract to/from a chain".

The post is from Postabilty  and my Misc Values are turned off . This has happened before its seems when I work with a file for a certain length of time one of the tool paths become corrupt. The only way I know to fix it is to reprogram it from scratch

you don't want all of them turned off

this behavior is caused by the Start OP Ref and Mid OP Ref mics intergers.

If you don't want automatic retracts, set them to 3

I never have them on and its never been a problem

It depends on the tool path..  try experimenting with those switches.. it will fix your problem

[ujmujm]

I will give that a try, I sent my reseller a zip to go  file and they sent it off to Postability we'll see what they say, I'm wonder if its Mastercam 2018 I've had a few issues this version one of them is saving my work which I learned 30 years ago to save often and version 2018 that doesn't seem to matter some times it will save it and sometimes it won't at first I thought it was me but a coworker come up to me yesterday and asked me if I was having that problem so I guess it isn't just me, also when I use Dynamic Planes I like to select the entity from the auto cursor menu but everything is grayed out!
