CamBam help (General usage) / Mach4 advise?
« on: September 05, 2023, 01:25:42 am »
Well my 27 year old computer croaked so I had to add a motion card to the system so a newer computer could take over. I also moved to Mach4 for the mill. The lathe has been mach4 for a long time now. When I made the change on the lathe I had to make a few subtle changes to the post processor. Is there a dedicated pp for mach4 mill? Are there any other suprises I can expect?

CamBam help (General usage) / Re: Strange behavior of pocket MOP for some fancy text
« on: August 15, 2023, 00:39:26 am »
In my experience when I get unpredictable behavior it's usually a problem with the dxf file. Open poly or some kind of irregularity. Check the lines in the problem letters to be sure.

Those are a pair of 9 cylinder radials I have been picking away at for a few years. They are a one inch bore so pretty big for me. I would post a few pictures but I need to resize them and street outlaws is on the telly so maybe tomorrow.

Over the years the controls alot. In 1959 when they first came out there were 2 levers. One for brakes and one to shift from forward, neutral, and reverse. They are only one speed forward. In the 80's the brake pedal and centrifugal clutch showed up and there was a shift handle under the seat to shift from forward to reverse. I also have one that has a brake pedal and drive pedal. You shift into forward or reverse and then press the pedal to tension a belt and away you go. 3 different cars, 3 different control schemes. This model has the oldest setup with the 2 levers. All cars had the throttle control on the steering column unless the owner moved it.

Coming right along. Added a few more pieces.

Problem dxf files etc... / Re: Fixing an STL file
« on: February 08, 2023, 20:54:15 pm »1 - Sometimes I can "force it" if I change the increment levels. Either by changing the depth increment or by changing the stock surface.
I know that's not the clean fix you want, but sometimes I have so much work invested in a mesh that going back to blank page and starting over is like a kick in the stomach.
2 - Often waterline chokes on stuff that works fine with horizontal or vertical too.
3 - If you are using the waterline for roughing you might also try taking silhouettes at your depth increment and using those to perform 2D operations.
4 - If all else fails you can start over making sure to do clean booleans so you have a single watertight structure, and run a "clean" or "Simplify" operation on your source geometry before exporting the STL.
If you are working with an STL created by somebody else there is not telling how much garbage there is inside of it. It might not be salvageable.
1 - Yes I have played the "depth increment" game before and will probably have to this time.
2 - Yep! I plan to finish with a horizontal and that tool pathing looks perfect.
3 - I thought about that but every corner inside and outside has fillets or radii
4 - Yeah I don't know what 75% of that means. I don't think Alibre has a simplify or clean funtion.
5 - It is my own STL made by Alibre. I have removed all internals. Other than the surface I want to machine it is a solid mass.
I'm going to try to play with the levels and see what happens. Thanks

Problem dxf files etc... / Fixing an STL file
« on: February 07, 2023, 20:53:41 pm »
I have 2 STL files that look great until i try to waterline them and get multiple open poly errors. Obviously the tool path reneration does not go well as you can see. It goes well until the 6 or 7 layer and then starts to cut closer to the boss eating material it shouldn't be.
Is there a way to fix? open poly's. Tried to change settings in my drawing program. I tried opening in Freecad and exporting. I tried online fixers but they degraded the quality to an unuseable level. Not sure what to try now. Are there any work arounds or opimizations that cambam can do to work with this problem? Think I already know the answer but thought i would ask.

Couple pix with the wheel hubs in them.

Thanks.
Yeah the brass was a few bucks but easy to work with. The shame of it is it will all be painted. I'm also going to make wood spoked wheels. When they are done they will also be painted. The standard car was black with red wheels and a gold grill. Unfortunately that's what I'm doing.

Couple more.
I added one shot of the full size car. The parts in all the other photos are 33.3% in size.

Just showing a few pieces CamBam helped me out with. The go-karts are 1/2 scale 1910 Model T Fords. They were built buy Snapper mower before Snapper was Snapper. I used CamBam to make a 1/3 sized front axle and transaxle cases. Soon I will do the spokes for the wheels as soon as the storm moves on and I can get some wood and a collet.

Post Processors (*.cbpp) / Re: Need a little help with Mach4 Post Processor
« on: March 24, 2022, 13:49:55 pm »
I would have to look bur I think I had to remove the underscore from the $R so it would be present on every line. For G83 there were 2 variables that needed the underscore removed. Again I'm guessing and would need to check.

Thanks. For the record I did do a search and nothing came up. Must have screwed that up a little.
