I have to make an aluminum part that has a pretty deep cavity that has undercuts. I have a 40 taper machine and the part is coming off the lathe so most of the inside is machined out already. I have no experience with long tooling like this that is capable of doing the undercut. Any suggestions would be nice. Here is the file. Thanks EMASTERCAM.mcam

Thanks for all your help. Yes im trying to do this on a 3 axis. I started out using a lollypop tool but realized I could not hit the full radius. With the lollypop tool I was getting some pretty good toolpaths but when I switched to a key cutter it went crazy. So it looks like I just have to hit as much as I can with the lollypop tool and thats what they get!

Hello. I'm trying to get a clean toolpath for this radius. Its on the bottom of a 1/2 inch hole. I am using a key cutter with .03 rads on corners. Been messing with it for a while and can't get a smooth path. I would appreciate some help. The file is attached.... Thanks UNDERCUT.mcam

I messed with this for so long trying to get it to come out right. Never was able to and finally gave up. There was a thread on mastercam.com that talked about a fix for the bug but I couldn't get that to work either.

I do. And remember I have seen it on two different computers with 2 different graphic cards. I cannot make it repeat either like you.

I do use multiple screens and have my toolpath manager docked on separate screen. I don't know how I can work otherwise. I guess I will just have to deal with it as I have been doing. If the multiple screen is the issue than I would think that many would be experiencing this problem. So why is it so random then?

So for a while now I have seen this. Its random and unpredictable but happens frequently. For example when using Bounding Box. The dialog box will pop up to set the parameters and everything will be grayed out and not register my mouse clicks visually even though it really is registering the clicks. If I then click in a text field to enter a value for the size of the bounding box it does not register visually that I am in that text box. BUT as soon as I start to type a value the whole window suddenly becomes in focus and like normal. This happens on other things as well, Not just the Bounding Box dialog. It has happened to me on multiple workstations and was doing it in 2018 as well Anyone seeing this thing pop up?

I tend to wait 2 weeks to a month before jumping to next version. Not because im afraid of any Gui changes but because im worried about bugs. I feel that 2 weeks to a month is long enough to see if there are any rants on Emastercam.com or mastercam.com forums. If I don't see anything major then I go with it. Off course I leave the previous version installed unless I need disk space for some reason, which usually is not a problem.

I learned my lesson years ago and now I alway save backups to key files and folders once a week. You just have to do it now. Especially if you have everything customized. It would probably take me a good day to get my setting to where I have them now if I started from stock setup

Spacemouse pro. Best bang for your buck. I got mine used on ebay. Have not had any issues with it. Here is one. Spacemouse pro

Would be nice to have the option to toggle on and off pecking in backplot!!

I loved it. Was way faster and you could tell it was going to peck but you didn't have to visually see it doing all the pecks. It looks nice seeing the pecks I agree and is what the machine will do but its painful when doing backplot. Time waster in my opinion.

but is this a change for update 3? Because in update 2 it was not the same. I remember when I first got 2019 it showed all the pecks until I put subsequent peck to 0. then it did not show all pecks but still posted out correctly. That's if im remembering correctly. kind of fuzzy

When backploting a drilling toolpath I just hit the s button. For some reason now its showing every peck when It used to show only the first peck and then drop down to final depth. I liked it to just show the first peck and then drop down to final depth because it was way less time on the s key. I don't know if something was changed from update 2 to 3 or if I changed something without knowing it. How do I get it back..... here is what I have

that works if you think of it that way I guess.

I try to think of it like the model on the screen is in my hand that uses the 3d mouse. If I wanted the part closer to me I would pull it toward my body. That's the natural way I look at it so I leave it at the stock settings for zoom. Tried it the up/down way and it made me dizzy.

That makes more sense. I just downloaded no problem. sig updated Thanks Pete

Same here. I was prompted for a few days but was too busy to update. now I go to help/check for updates and all I get is a message that says no updates available. Im going to wait a few more days just to be safe. That kind of scares me

Finally got around to doing this on my new laptop 4:37

It most likely doesn't have anything to do with winrar. Probably some of the script is wrong.

Here is my setup...…

Its no TOY!

I think you nailed it right there gcode. I did that right off the bat and got hooked to the thing instantly. Every once in a while my rotation origin will be off and I just orient it to center of the model because its impossible to manipulate the model fluidly like that. If someone doesn't know about that one single adjustment they WILL put it in a drawer and forget about it. I personally have been using one for over 10 years. With all the buttons programmed and in conjunction with my Logitech G502 with its 11 programmable buttons, I really only need to touch keyboard for typing comments and my mouse pointer movement is kept to a minimum. If you have one in your drawer, Take it out and do what Gcode says. I would say it makes my workflow 25% faster.

That's the first thing I tried. It didn't work
