Sorry about that. I'm off work for the rest of the week so I won't be able to send you a file until Monday. I could make a short vide if you are interested. I'm not 100% sure if that's what you really need but it may help.

I learned this toolpath here and it works great. Triangular mesh. you have an open book of options. 3D High speed Equal scallop works as well. both toolpaths are in the file, take a look and modify as you need it. Roughing Test.emcam

I forgot to mention that you can have stepover or number of passes.

Not really, but do not change the subject. He already have 3D curve. Transform offset the 3D wire frame by .045" then you have your second Chain. Blend works fine. I do not have 2021 here I did it on 2024.

I believe you have to update your post too. We got same machines here. T2 (0.625 BULL-NOSED ENDMILL) M06 G54 G17 G90 S1742 M03 G94 G05 P10000 M79 M11 G00 A-90. C90. G68.2 X0. Y0. Z0. I270. J90. K0.

I sincerely Apologize for interrupting your question. You were going to get help from the best, I'm sorry. I read here that you have to have Stepup Check. if you do not want to do the stepup , Stepup and stepdown should match. I see your part has an angle stepup Should be better for the finish tool.

I have to use my previous Stock model. Like this It's been working for half an hour and it doesn't do anything.

When I use a solid model for my tool on Mastercam 2024 update 3 I cannot create a Stock model. I use Optirough all the time then stock model, after that Optirough but this time with rest material with smaller tool , one other operation and select stock model, after that I create another stock model using those operations as source operations and I cannot get a new stock model'. If Iuse a regular tool it works. I don't know if I explain myself. If not, I'll send pictures later on. Coul you please create I stock model after that operation using that operation as source operation and let me know if you can create the stock model operation. When you have time. it doesn't work for me 2024. are you on 2024? if I use a regular tool it works, I tool from Mastercam. Thank you.

mirek1017, is out of your question. But I need your help after you're done. could you help me. are you using a solid model for your tool definition?

I believe since the beginning, Mastercam X7, know it's worse than 5-7 years ago. It's just a waste of time using solid models for holders and tools and on top of that if you use stock models you end up with not working stock models. I created mine 9 years ago, X9 now in Mastercam 2024 I have to rotate the solid models in order to making work. but by mistake I learned that if you change the level's name to NOCUT, now you're able to edit the geometry in the parameters, Maybe it's been like that for years and I didn't know. '

stand-alone Tool Manager is powerful tool, I use it a lot, too bad that you cannot use solid models to create holders. It's very confusing to use DFX files, every new release of Mastercam changes the way you can Import the geometry. The same DFX file that was Created in Mastercam 2022 cannot be use in Mastercam 2024. If you go to help page the information is not up to date, still from Mastercam X7. What I like the most is that I use it to get my feeds and speeds from the Cut parameters.

You need to read the fine print. Yes you can edit a tool holder from a solid model. Any tool holder that doesn't contain radius on the profile can be modified. I know is a lot of work and takes time. I agree with you, is a waste of time. We just want to grab the solid from the vendor and make the adjustments.

Thank you, Aaron, for your quick response and the advice I really appreciate. straight forward explanation and it really works better on the corners, the C axis is not rotating like crazy, and the finish is great. Tool axis control makes a big difference. I still struggle a lot with tool axis control and collision control. I was using Curve parallel because it gives me the option to extent to the side of the curve. Curve parallel gives me that option. i was trying to machine the material on the corner from previous operation. Curve guide doesn't give me that option, I guess it has different options, and I will try to check those options.

I'm using Unified Curve, Parallel toolpath to finish the radius at the bottom of a pocket. My tool is almost the same radius as the corner radius on the part. The step over is fine until the tool gets to the corner it gives me a very tight step over. Could please show me how to get rid of the tightness. I tried advance options for surface Quality, Step over calculation. Nothing helps. The reason I'm using Curve parallel is because it lets me extend outside the curve and clean the corners. I do not know if it does that because the surface is not parallel to the curve. any help would be appreciated. ath to finish the radius at the Part2.MCAM-CONTENT

I do not know how confident you are to try. The lines where you want the whole code to disappear are easy. Ex. find: pbld, *n$, *t$, "M06", ptoolcomm, e$ add # in front of: ### pbld, *n$, *t$, "M06", ptoolcomm, e$ do the same for the next and so on.
