Thanks Mathew No longer needed.

Had it happen to me never took the time to find out why just went with the fact that it backplotted fine and moved on. Jeff has a good sugestion. I never have had the tool in the same file as the part, it may help?

open your machine def. then ensure the proper boxes are checked here:

If yur on maintenance then call your reseller and have them walk you through the procedure to fix otherwise.... Some will be with you shortly, we are experiencing an large # of call please be patient and someone will assist you shortly.

Thanks Pete

I believe it is a cadkey.

Anyone out there have a suggestion on a converter? I can view the file but when I try to open it in MCX2 it asks for an access code. Which I'm told has not been set.

MillingMan I sent you an example how I performed this.

Yes that would be correct! They actually move the opposite direction that they are programmed. (not 100% exactly how it calculates it's position, or if that last statement is a 100%, but it is wrong anyway) Generally I will use the default jaws values and only change the positioning (OD, ID).

I can't recall if it is calculated, haven't checked it out in a while. I have alway selected a point then adjusted in or out from there. You have mail of an example I'm working on now! I mailed no file!! DOH!

I don't have any issues with stock flip except that it doesn't verify properly. I use it on practically every part I process. One file for one part. Leave original position at zero.( assuming this is 1st op zero) Transfered position is the left side of the part. (or the largest -Z) Wherever you assign this is where you will move the part to zero. If you don't want to see the prior to flip geo check the box to blank it. Use the radio button and have it change the entities level, then turn off the 1st op level. I leave it the same level and use the blank check box, but until you fully understand how it works I suggest changing levels that way you don't destroy the original geo. Final position is reffering to the chuck in relation to its previous position. Be aware these operation backplot correctly but DO NOT verify correctly.

If you set them 5 years ago, don't you think you would have saved some time by now? HEHE

One last thing on this issue. Wouldn't it be nice if you didn't have to create the additional geometry to get the desired result? And then have it verify properly? And, no it does not effect my code. But as I stated before it negates the use of verify. An Idea for CNC, make it react as a machine in canned cycles would. (easier said than done I'm sure) I wonder what will come of this when they offer machine simulation? And I think I need to apologize to you all on the boards. Sorry for coming off negatively as of lately, I'm not trying to be negative I'm trying to point out errors and ensure these things I find are not user error in the hopes of seeing them get fixed.

No Problem Millman no need for apologies!!! I used to use regular cycles exclusively prior to this position. At this new position all they have ever done was right code by hand in canned cycles. I am trying to get code that looks similar. Similar being the key word here, not exact. We reuse programs here a lot, as sometimes all that changes is material. So canned cycles come in real handy for changing from inconnel to a bronze. But I'd also like to be able to cram the largest tool in a job that I can. So I guess as long as I'm aware of these error I can deal with them. But it kills the use of verify and backplot!! I was hoping I had something set wrong!! I don't like not being able to see whats happening .

I got it it's clearing stock previously removed. Whereas a machine will clear .02 from it's last X cut position. Machine: ex. cut at X2.4390 retract position X2.399 difference of .02 radially MCX2 calculates that line equal to the first cut position (2.439) and exits at 45deg with X.1 clearance(?). It does this when the leads box is check as in the 1st example of my last post, with nothing checked in the lead dialog. And it repeats this for every cut + .1 ex. cut at X2.4390 retract position X2.2390 .1 radially Why I don't know? Is this a setting in MCX2?

here's a pick with the leadin/out check with the sub boxes left unchecked both of them in and out Here's the same toolpath with leads box unchecked

Slightly modified from when I posted but still get those additional angled lines. I'll up the file if you want to see it.

I was hoping someone could tell me what parameter I need to modify to remove these tool path lines from this canned cycle. Here's my parameter page: my lead in is add a line .100 at 0deg no lead outs checked tool clearances are at .02 and tool clearance: Am I missing something? The minor on that bore is 2.469 but I can not use a 2. Bore Bar. the back of the tool crashes the part. But I know that the machine will not follow this path. It will back off the overlap amount and run fine. Am hoping I have something set wrong. Any ideas what I can do to either fix this or work around this are welcome.

Well the results are pretty much what I expected. Very few people using canned finish. Anyone want to explain why? Especially like to hear the 2 yes vote on canned finish and what they are doing to use it and get good output with no modifications. I'd like to see what I can do to make it work right for me without editing. And of those using canned threading are you using G76? If so what are you doing for lead-in angle?

You ever get that file?

You need to go into your post and find this area: and use switch sign from basic #Machining position turret/spindle settings # Switch strings based on turret position top/bottom-left/right and cut type. # Turret position is based on the Mastercam settings (see lathtype). # Strings are re-assigned for output in the routine psw_str_mult. # The string variable sw_string holds the place position value to determine # how to assign the strings. Planes are relative to the view from Mastercam. # Assign the 17 digit string following the alpha columns below: # A - C axis, 1 = axis winds, 2 = axis signed, 3 = indexer # B - Spindle direction, 0 = normal, 1 = reverse # C - Plane 0 arc/comp, 0 = normal, 1 = switch # D - Plane 1 arc/comp, 0 = normal, 1 = switch # E - Plane 2 arc/comp, 0 = normal, 1 = switch # F - Plane 0, 0 = G17, 1 = G19, 2 = G18 # G - Plane 1, 0 = G17, 1 = G19, 2 = G18 # H - Plane 2, 0 = G17, 1 = G19, 2 = G18 # Decimal (required) # I - Plane 0, X axis, 0 = normal, 1 = switch sign from basic # J - Plane 0, Y axis, 0 = normal, 1 = switch sign from basic # K - Plane 0, Z axis, 0 = normal, 1 = switch sign from basic # L - Plane 1, X axis, 0 = normal, 1 = switch sign from basic # M - Plane 1, Y axis, 0 = normal, 1 = switch sign from basic # N - Plane 1, Z axis, 0 = normal, 1 = switch sign from basic # O - Plane 2, X axis, 0 = normal, 1 = switch sign from basic # P - Plane 2, Y axis, 0 = normal, 1 = switch sign from basic # Q - Plane 2, Z axis, 0 = normal, 1 = switch sign from basic What John said.

Thats why I started this, I want it fixed. I want to use Canned cycles efficiently, without having to use geometry lead-ins, reference points, hand editing.... As well as canned threading using the 29 deg lead, which is much better on the tool, without having to use a misc.real to set my start point since using the 29deg lead will give you different Z start positions scraping a part if you don't remember to edit the program. Lathe needs some attention. I do lots of expensive 1 and 2 offs, 10 to 15 a day and the list of things I have to remember to do to get safe productive code is becoming longer not shorter.

Crazy^Millman Exactly what I do but if CNC were to alter the output then you could skip a couple of steps there. Ref points and creating the additional geometry. The crashing problem is due to the start position output from the canned finish on G71. Which makes it impossible to do an order of operation as follows (N20 AND N40) with out editing the start position from the referenced rough. code: N20 (1" S16-SCLPR3-CPGM-32.51) (80 DEG .0156R VECTOR 2) (ROUGH ID) G0 G40 G54 G99 G50 S2500 G30 W0 G97 S1630 T0000 M3 / G1 X1.5 F.9 X1.5 <<<<<<<<<<<<CLEAR OF STOCK Z.1017 M8 G96 S640 G71 U.075 R.02 G71 P22 Q24 U-.03 W.002 F.01 N22 G0 X1.6149 G1 Z.0012 X1.5452 Z0.

I blew it with the last question #5? you have to reply to it!! DOH!
