CamBam plus 0.9.8

[blowlamp]

I'm trying to add a tool to the Default-mm folder, only when I come to save it, I get the error message 'Access to the path is denied'. I can save tools elsewhere without problem, but wondered why the Default folder can't be added to.

Ah yes, I wondered how much of a problem this would be.

The easy 'fix' is to go 'Tool - Browse system folder', then in Windows Explorer, go up a level and do right click, properties on the 'CamBam plus 0.9.8' folder.  Now in the Security tab, give your user account 'Full Control' permissions.

Alternatively, in CamBam's system configuration settings, you can change the SystemPath property to point to your user profile folder... 
{$user}\CamBam plus 0.9.8\
...or an alternative location.

From a security, best practices point of view I should perhaps make the user profile the default location for the system folder.  Personally though, I prefer the common application area.  Especially if installing on a machine with multiple users.

Andy, found an issue with the new 'post' system.  The new system works great, until you load an older .CB file.  The old .cb file doesn't know about the new posts, so if you save a g-code file, your post changes aren't applied.  Bad things can happen 

If an older .cb file is loaded, you need to automatically set the post to the post called in your template file, so it will be used when creating g-code, and saved in the .cb file when it is saved as the new version.

Hi Don,

Is this the same problem as in this post?...

Sorry for moving the location of the post files on you but I thought it best to keep 0.9.8 separate to 0.9.7.

Completely different problem.  Only occurs when loading a pre-.98 .CB file.  Everything works perfectly on new files, and .98 .CB files.

Everything else converts and works, i.e: all the MOP settings.

What it doesn't reads the post that was used when the file was created. That could be 3 years or so old. If the name isn't found, It uses a default un-modified post.  That can cause some problems if there are important things in the post you are using. 

Can be worked around, but easy to forget to change to new post before creating G-code.  It may be because the names of my post have changed slightly as time goes on. 

For safety issues, I would thing that old files would be set to use current default post, the one that is loaded in the template file.  Also, as time goes by, things are added to post files to make them better for your use, ot changes in your CNC machine, making the old ones obsolete. If not changed to the current post, at least give an error dialog stating that the post in the .CB file doesn't exist, and a default will be used, so we know to change it.

Does that all make sense?

Yes, I think as you suggest a warning message should be added if the post is not found.

I was also thinking of adding a default post processor option to the Tool - Options settings.  So you could still set it in your drawing template, but if this was blank it would use the default system one.

Thanks Don!

I just noticed that Climb and Conventional milling strategies look like they're mixed up if I have OptimisationMode set to None when cutting a pocket.

Martin.

Ah, I see what you mean.

The toolpaths are in the same cut direction as the optimised ones but because they are output in the order they were generated they are going outside in, rather than inside out as the optimised ones do.

I think the toolpath order just needs to be reveresed when OptimisationMode=None is used.
I looks like 0.9.7 was doing this OK. 
I'll put this on the fix list.

Thanks Martin

Andy.
Does that mean that the cut then will start in the centre and work its way out to the edge, because I was trying to force an outside to inside strategy for this job?
I would like to remove all the outside stock from this part without doing any plunge cuts if possible and the ability to change to an 'outside inwards' strategy would be nice for doing this.
I'm finding the new Stock and Part features to be very nice  thanks!

I have a round part and wanted to add 3 tabs. I set up the tab parameters as manual and min=2 max=3. When I generated the machine code, no tabs appeared. I then set tab to auto and regenerated. Now I get 4 tabs!  I can't seem to get the 3 tabs I want and I don't understand how manual works.

Cheers,
Michael

Hello

You can add or remove tabs by following this steep

- select the MOP that have tabs
- on the drawing right-clic on a tabs you want to delete and select "Holding Tabs/remove tab" in the context menu

You can change placement of tabs by clic and drag it with mouse.

Same think to add a tab -> "Holding Tabs/add tab" in the context menu

for automaticaly obtain 3 tabs, you can try to set min and max tab to 3 and then use "Holding Tabs/autocalc" in the context menu to refresh the tabs (or setting "TabMethod" to Auto and generate toolpath again)

Thanks David. That did the trick.

I have used 6 of my trial starts of CamBam Plus. I have been using 9.8 g & h til now. I just got my cnc router finished a couple weeks ago so I'm new. Today I was engraving a pattern of squares app 3/4 in. layed out like a single array of 15 squares. Each of these have a smaller square inside of it and each of them has a smaller square inside of it and each of them has a still smaller square inside of it. I hope this explains my pattern. When I produce the tool path it put in cuts between some of these squares - either vertical or diagonal. Looking for the solution, I downloaded the newest stable release and it produce a correct tool path. Ive spent the last 10 months designing and building my machine and so I've been looking at all the CAM programs available and I am sold on CamBam. My plan is to build jewelry boxes with very small patterns and engravings on them. I will keep playing with the latest editions because I'm still learning - and I really like the new features you are adding. Very COOL intuitive program.

Gary, I'd been using G-simple for most of two years on my restored R2E4.

A friend recommended CAMBAM.  After using it about ten days, I purchased it. 

GSimple was free.  CamBam is a better deal!

I'm wondering if the Toolpath View Filter is working as intended. In short, I don't think things are being displayed in the order they perhaps should be for maximum effect. I mean, shouldn't the Profile MOP be shown in its entirety (in Toolpath index mode) before showing any of the Pocket MOP, so you can follow each toolpath start to finish?
I hope the video explains my point.
