Are you referring to a page in the machine control here? I'm mostly at the MC seat, so I don't get to poke the buttons on our VX660 too often, and I can't see where these settings would be in MasterCam

Fie on you, Lazy Guy! Thanks for the tip, I'll be on the lookout for self-destructive solid bodies.

"Used or Named" radio button did the trick! Was set to "Named", didn't notice or use those buttons before, thanks a million! Seriously, thanks so much, I have been struggling with this issue constantly as a minor annoyance. Never had a super complex file that I NEEDED the wires from until today.

At our shop we have 1000's of programs made in earlier versions. Most register as "MastercamX6 Part Files" in explorer. I have only been around for a year, so most of them I have never seen. I can open them in 2021 or 2022 for re-posting or grabbing a setup sheet, no problem. The issues start when I am getting wrist deep and starting modifications/uprev's or trying to make some hi-speed versions. Many, if not all, of the files have the part solid, part wireframes, surfaces, and toolpath driving wireframes completely invisible in the Levels manager. As in the levels don't exist - but I KNOW the geometry exists. Why do I know? Toolpaths are usually fine, and the Chain Manager will show the wireframes as "Chain 1, 2, 3... etc" or whatever it may be when its open. That's the only time I can see these particular wireframes/edges. Is this a common issue when opening older files? My initial thought is that the issue is similar to when you don't name a level, and you can lose the level in the manager, but the geo still exists. Maybe the X6 level naming/numbering system doesn't import well (or I am doing it wrong, by just opening it)? I must confess that 2021 was the first CAM system I have used, so I am totally stabbing in the dark as to how the older versions worked. Any help would be appreciated! And may I say that this forum and its denizens have been an incredible companion as I started, and now continue, learning MC - and develop bitchin' CAM habits in general.

See above thread ^^ A veritable wealth of G131 Mats knowledge, helped me figure it out. Happens to be about your very machine. Hope you get it running quick and smooth, my guy!

Yes. I don't think MC is set up for GPU compute on toolpath calculations. I could be wrong, but I'd be surprised if true,

R-25913 has been a pain, the memory error prompt freezes up my pc sometimes, glad it is fixed. Never put 2 and 2 together that it was related to verify though. Thanks for the post, my guy

After installing 2022 on my machine, trying to open .mcam files from Windows explorer results in the 2022 installer launching. I looked at the default program options by extension in Windows, and the .mcam extension is using 'McamVersionSelector Executable'. I'm sure this should open Mastercam 2020 for files last saved using that version, and 2021 or 2022 if that was last used. I don't want to just default all .mcam's to use 2022, as I don't want the older files constantly being updated to 2022 (we changed the posts and m. def locations etc.) when I want to make a small change or repost for a different machine. Anyone else had a similar issue?

in 2022 the Linking Parameters for waterline and a few other 3D toolpaths is totally different. I am by no means an expert, but it has the power to do a few more tricks than it used to. I'm thinking this might be getting in the way of how we approached this path in the old version, and I have gouged with it too. This video has a quick explanation at the end about the new features of the Linking Parameters. HTH, b'y Below MasterCam offical video is waaay better than what I found..

Metallic. I should have looked over here before I posted a longwinded reply over the Auto Region thread! Try an Area Mill op as a finisher with Auto Regions, and use the Expand Regions checkbox in the Air Regions section of the dialog. Might do the trick, b'y

For sure, it's the Expand Region option that I love. Forgive me though, as I may have misrepresented my position - I considered the edges shown below 'outside corners' as far as an open pocket is concerned. We get them a lot here. Below I have a super simple example of the Expand Regions checkbox on the Auto Chain dialog, just adds a little to the material to be cut and follows your avoidance selection, part geo, etc. It's a quick way of keeping the vertical highlighted from getting sharp, saves some deburring time, and dodges a few finger slices. The time saver for me is not having to set up a separate contour path after the pocket routine (finishing not withstanding). It's a small thing here, but a more complex part will benefit. As will parts with many pockets, or nested pockets. I'm making a genuine effort to use solid geo for my selections, and this tool is helping me reduce or eliminate laying down wireframes on my parts.

Had a training/2022 upgrade session 2 weeks ago, and have not gone a single project without using auto regions. Becoming just another step for setups in my book. It improves the selection process with such speed it feels like cheating sometimes, and the expand region (don't know if it was there before or not in the old dialog) is doing wonders for sharp outside corners on vertical walls. Especially if you're someone who is still laying down wires, don't overlook this tool!
