Hi,

I don't really know what is going wrong but here is what i found to make your toolpath regen.

I don't have 2020 anymore to get your file back but here is step by step process:

- Major issue is R2.8825 surface normal is reversed (Surfaces/normals/change)

- Limit R2.8825 surface to other flat surfaces (Surfaces/trim to curves)

- In toopath parameters 'cut pattern/advanced option' tab, change 'step over calculation' from approximate to exact.

You'll need to make a stock model with hole machined and select this stock model in your optirough (will become optirest) toolpath.  

HSM pencil has a major difference over legacy: ability to limit it with a stock model.

Just check this video. There is a pencil example at 10:00 but whole video deserves to be watched.

I'm pretty jealous of your rigs guys!

Mine is 5 years old now (Xeon E5-1650 oc4.2/32Go/K4200/SSD) and it crunches benchmark3 in 4'03... fortunately our parts are usuallly medium size without complex surface features. However I'd like a new one to speed up things like GUI latency sometimes. 

Just enter 0.2 (0 dot 2)

G81 cycle will always go back to R or Z plane then G83 will always start from here. This is part of the cycle process and there is nothing you can do about this. Or use 'advanced drill' command for a fully customized cycle.

Yes that looks nice.

Here are others video from official website

Model prep commands should do this easily

You can deactivate them in ribbon bar customization. You need to uncheck Tools ribbon bars.

Yes, this is to clearly separate setups and you can select different machines easily.

 I noticed you have 2 stock models.  1 as a single part, and 1 as both parts.  You included both, just to show both options, but would normally only have one or the other, correct? 

 

The first one is an exact copy of your 'finished OP1' stock model but with stock part_1 only. I did it to export mesh for part_1 only, copying/transforming this mesh to make OP2 part 2 stock. This stock model toolpath can be delete after meshes export. I let it in the file as it's part of the process. 

There are several ways to make it. It depends how you want to organize your work. On complex parts i usually make one file equals one setup.

However, here, part is simple so it'd be perhaps better to get all setups in the same file.

There are several ways to achieve it but my strategy is usually to move fixtures (not part designs) and use WCS/viewsheets.

In your case it's a little tricky as you're using one stock model for 2 parts. I usually keep 1 part per stock model (except if i need to verify) it makes things easier.

Then, I made a mesh from your OP1 stock model for 1 part only and made a copy of this mesh for 2nd part. Then make another stock model from these 2 if needed.

I updated your file here: https://www.dropbox.com/s/ehick6vmsajvzl7/333A072-mod.mcam?dl=0

We had a lagging issue with a 2021 seat. Here issue was related to 'shared' folder on network. We couldn't find how to solve except moving shared folder locally. 

Tu as essayé de changer le symbole décimal dans les options régionales de Windows? As tu installé les dernières Updates de Mastercam 2020? 

Je suis sûr d'avoir déjà lu ce problème ici ou sur le forum officiel. Faut faire une recherche.

Edit: Il y a un post sur le forum officiel qui parle de ce problème http://forum.mastercam.com/Topic33710.aspx?Keywords=comma+field#bm33711 mais apparemment ça ne toucherait que les fichiers DXF/DWG.

Here is a quick example with curve5x.

Do you have a "Default" Advanced Drill Operation, in your Mastercam Operation Defaults Folder? (If you've been updating the Op Defaults for a while, you might be missing any "new Operation" Op Defaults.) I had an issue when I first fired up Advanced Drill, but I haven't seen the warning since encountering it the first time. I don't think it should effect you when "importing" an Operation from another file, but I suppose I've seen stranger things happen.

That was it.

I had a message creating new advanced drilling operations (probably migrating operation defaults from 2020). I saved values using and importing from another file is ok now.

One other thing is to save these to a ops library and then you can import them in as needed for other programs. This will take some to build up, but as you make them save them all into one place and then you can pull them as needed.

Does this effectively work? I'm asking because i recently tried to import an advanced drilling operation from another file but drilling parameters were reset to default.

It doesn't sound like the simplest way to me. Try the method I (with the help of JP) mentioned above. 

Create point position-Autocursor Relative-click your corner- type in your XY position.

Even simpler, just maintain shift clicking existing point (shift is hotkey to relative autocursor)

maybe i'm dumb, but i just put a point in the corner and then use translate/copy

Yes, there is a lot of different ways to make things in Mastercam!

Another fast way is to make point, Analyze (F4 key) and change coordinates in fields.

You may use incremental value using Gnomon.

To position, Just click existing point maintaining shift key, then click gnomon arrows to enter value (or drag it using scale)

I have a similar issue but with 'cutting' tools. Is there a way to save it to a library once a holder has been attached (without need to attach 'default' holder)?

Yes you may use migration wizard and select specific folders/file type you want to update again (then it will ask you if you want to backup/replace files previously updated)

We're running an Integrex200-IV Matrix here (without lower turret but with sub spindle,y axis and 5 axis option on main spindle). I could help but issue is I'm off until 08/24 without a Mastercam seat...

Control parameters and installed options can involve major differences in NC code output but feel free to post a NC program and i'll check if I find something weird.

I guess you could already use several closed chains air regions but not opened edges like in this video.  

It comes from official Mastercam website here https://community.mastercam.com/techexchange#files (there are sample files too)
