    Avoidance surfaces

    Just to add, in X9 I guess you were using Surface Finish Scallop which allows Check Surfaces. The toolpath you showed above is Surface High Speed Scallop; its a different toolpath and it doesn't support check/avoidance surfaces, even in X9 (or rather, it would let you select them but then machine them as if they were drive surfaces) The old Surface Finish Scallop is still in 2020; you have to right-click in the Toolpaths Manager then go to Mill Toolpaths and Surface Finish.

    Creating grid?

    That function doesn't exist anymore - quick history lesson! Around about the X9 period the Create/Point/Grid was removed and rolled into the 2D Drill toolpath as an option called Pattern. Since around Mcam 2018 and the redesign of the drilling dialog that option went away too. If you just want a grid of point entities then the suggestion of heavychevy2155 would be the best way to go I think.

    Toolpath for machining a fillet without a form tool?

    Well well look what I found! The method I suggested was in the Mastercam Handbook Volume 2, circa 2002 written by San Diego CAD/CAM (Charles Davis) for CNC Software. It was discussed as an option to clean up shallow areas of a component.

    Toolpath for machining a fillet without a form tool?

    Thanks guys - I'd like to say that I first read about this in a Help file or What's New file dating back to perhaps the V9.1 period... I can't really remember now! I remember the image that was used in an example, it was a bit like a aerosol cap with the "containment boundary" going from the centre out to the edge.

    Toolpath for machining a fillet without a form tool?

    Yeah I'll knock one up for you It'll be toolpathed in 2018 so you won't be able to open it in an earlier version. Test_piece2_RT_2018.mcam

    Toolpath for machining a fillet without a form tool?

    My Turn! I read many years ago about using a "tool boundary" perpendicular to the cutting direction with Surface Finish Contour. It helps maintain a constant stepover relative to the chain, a bit like Scallop or Flowline. Take a look at the attached file and look at the containment boundary I used. Test_piece2_RT.mcam

    Pitch in your little gems that make mcam life easier

    In the Bounding Box function I find it a tad frustrating that there's no "reset" button if you have been editing the bounding box extents and decide you quickly want to start again from the initial values (no... I haven't logged this as an enhancement request but I will!). I usually select the "manual" button and reselect the geometry I am working with, or press "All shown" if I want to put a box over all the geometry on-screen. However I discovered this week if you just set your Gview to Top, even if you are already in the Top view then it will reset the bounding box values to their original settings. In my limited testing this seems to work best with the Top Gview; Front or Right Side gviews don't seem to reset the values.

    Modify Probe Backplot Feedrate ?

    I can't find an easy way of editing the feedrate either - if you get no other answers I do have a "last resort" you could try! It uses the Toolpath Editor to change the feedrate. Please note that this method then locks the probing operation (you'll be familiar with this if you have used the Toolpath Editor before). Please see the attached video - sorry for hovering the cursor over the "undelete" function near the start of the video, that wasn't intentional! 2019-11-15 10-26-53_Trim.mp4

    Opening V7???

    X2MR2 only goes back to MC8 so it's looking like the original X. It's possible that a vanilla version of X2 could do it because I have a vague memory of a Maintenance update changing the oldest supported version of Mastercam files that you could open. Not sure when that happend though. Here are some MC7 sample files in a ZIP if you want to do some testing.

    Config file x9

    In the configuration (Settings/Configuration), go to the Start/Exit tab. In there you can set the "startup" configuration file - its the first option you can change on that page.

    Try going to the Post Settings tab (2nd tab in the 2nd image you posted) and there is a section near the top called "Select between the two solutions for startup". There are several options in the drop-down menu... have a mess around in there! EDIT - although the page is called Post Settings, you don't need to have a post processor attached to it to affect the simulation. Also I presume that you are trying to get the tool to start near the bottom of the workpiece rather than the top in which case those options will hopefefully help. If I misunderstood then I'm sorry about my rather flippant reply above!

    X9 GUI Menus not showing up

    I think what you will need to do - if I remember rightly - is shut down Mcam, is delete the default *.workspace file that the person is using (i.e. Design.workspace) from \Documents\My McamX9\Config\ and then restart. They will lose any modifications to the icons though.

    Lots of good enhancements

    Yep I use that button pretty much every day. I teach Mastercam and it's very useful to bring in an old programmed file and clear out all of the previous machining data. You might not see a need for it, but for me using Mastercam would be harder without it

    The Pencil toolpath is designed to clean up the intersections between walls and floors (the ball of tool needs to touch the wall and floor at the same time) and to do this it looks for sharp edges (for example the internal corner of the letter "L"). Basically if it cannot find sharp corners then it won't generate a toolpath. There are execptions to this... if there is a radius in the corners and they are less than the radius of your ballnose tool then you should still get a result. But If the radius in the corners are equal to or greater than your ballnose radius you can use the Overthickness command to trick the toolpath into finding enough material to run the tool between the floor and walls. I can see that you have already tried to use Overthickness so if you make it even bigger (try 0.1 and then re-adjust the stepover and number of passes) then you should get a resonable result.

    Converting part-files from VMC compatible to HMC compatible

    I'm not sure if the post is binned to be honest, I never took a look while I was on site. It might be something I can experiment with if I'm allowed a copy of the post.
