shoprat,

You may see a warning "style 'ROUTER' not found" when opening the file Bubba attached, just ignore that and continue, it looks like something he has set up for his own use.

See attached cb file.

1. Made a new layer called "Boundary"
2. created a rectangle the same size as the stock (polyrectangle1)
3. in the 3DSurface1 MOp set "Boundary Method" to "Selected Shapes"
4. in the 3DSurface1 MOp set "Boundary Shape IDs" to 1 (i.e. polyrectangle1)

To adjust how the tool cuts within the boundary shape, play with values in "Boundary Margin" it can accept both positive and negative numbers.

As Buuba said, using the file attached to the first post;

Upon producing gcode, the spindle speed is correctly set and the feedrate is correctly set.
I'm not sure any text in Tag will be shown in a gcode file, it looks like only the MOp name is included.

I have a fix for that but it might have to wait a day or so for an update.
The fix is to find the Centroid of each entity, if the X value = NaN then the entity is invalid and
should not be included in the entity list to further process.

Edit: new version 8.7 attached to first post.

Too many words for me  Wink

Here's my work flow.

1. create required 3D object in CAD software, Rhino3D in my case, save as stl file.
2. import stl into CamBam ( the stl created is the surface model included in my cb file )
3. apply 3D MOps using the most appropriate settings for the job in hand.
4. CamBam then does the work of creating all toolpaths.

No need to make it any harder than that.

I usually set the Tool number to 99 when posting cb files, I must have overlooked it this time.

Attached image shows where the tools are defined;

Manual - http://www.cambam.info/doc/plus/cam/ToolLibrary.htm

In the file you have modified a near tool size would be 1/4" ball nose

Dave,

Good alternative, I used the 3D method myself so that the same technique could be used on irregular slopes for example, but it's always best to have more than one method in hand.

Try the file I posted here; http://www.cambam.co.uk/forum/index.php?topic=7355.msg59350#msg59350

specially to Eddy who took the time and effort to create precise a easily to understand schematic along with detailed instructions.

Thanks, I used to get a lot of practice writing instructions, mainly to avoid call-outs through night when the electricians got stuck.

See diagram.

Assuming we need to exchange red and black to reverse;

1. Remove red wire from terminal 3 and attach to a new terminal 6
2. Remove black wire from terminal 4 and attach to a new terminal 5
3. Add new wire from terminal 4 to switch A2
4. Add new wire from terminal 3 to switch B2
5. connections as per diagram.

 
Assuming that the switch works like;
FWD
A2-1
B2-2
C2-3

REV
A1-1
B1-2
C1-3

OFF
no connections

Connecting one of the input phases to switch terminal 3 means the motor is isolated in the OFF position

(personally, I don't believe that... unless those two wires just happen to be to two separate field coils, and not the 'rotor winding')

Lloyd

I can't imagine this motor would have a wound rotor.

The last time I wired a wound rotor motor (and that was some time ago) it had a manual liquid starter, washing soda in water and it was on the gas washers of a blast furnace  Grin
In the same room there was a bank of large mercury arc rectifiers, it was like something out of a Frankenstein film, quite scary when under full load.

I'm reading on the label that it says, to reverse interchange red and black.
However with the switch shown there are other considerations.
For example, you don't want voltage across one motor winding while the switch is in the OFF position so the switch must be wiired to;
1. Isolate all windings of the motor in the OFF position
2. apply voltage to the motor as normal in both FWD and REV positions
3. reverse the red and black wires when moving from FWD to REV

It looks like the red and black wires ONLY should be reversed.

From the Smoothstepper manual;

"We strongly recommended (January 1st, 2016) that you use Mach3 version 3.043.062 (click to download).   The .062 release is the lock down version that works well, fixing stability issues experienced by people running version .066.

The latest release was Mach3 version 3.043.066. However, a number of people have had stability issues with their systems when using version .066.  The .066 version has had these issues for some users:"

Good news indeed, thank goodness for clever people.
