If you are still having issues after applying the "NoL", try going to the "Start" menu, "Mastercam X4", "Mastercam Launcher" on the other computers and setting the Lathe to "Inactive". I've had this problem with a floating seat of Solids.

If you are using X3, Rast_2_Vec is a free C-hook. In previous releases, it is an add-on.

David, When the computer shuts off power to the usb port, Mastercam will become disconnected. I don't know if this is the problem, but have seen it on laptops when the power save option is active or the hibernate mode is on.

David,

John, Go to Stock Set-up, Bounding box, select OK, check the XYZ values. Then go back into Bounding box, and look... The values are different. The values seem to cycle thru whatever is in the drop-down for that dialogue box. Just my $.02.

Using X3, I noticed that once Verify is launched, I loose my auto highlight and pre-select will display only after repainting the screen or slightly zooming or un-zooming. At first I would close Mastercam and re-open to fix the graphic issue, but noticed Ram-Saver will also fix the problem.

Most pipe threads have 1" taper in 16" length, so (1.3*.0625)=.08125, which would be correct if your "R" value is for taper in "Diameter". Divide by 2 and you get .040625, which is pretty close, if the "R" value needs to be in "Radius". This worked for a Mori, like g-code said, the manual is a good resource.

I think the "R" value = the length of the the thread plus the lead in amount (Total Z * 1/16), for external threadding it is a negative "R".

That looks like a good part for a lathe. You might try Scallop on the mill.

Check the box "Force Tool Change" in the second tool's toolpath parameters.

I like to teach "Planes by geometry" for the 2nd operation. Roll the part over so you can see the other side and select the "Planes" button on the Status Ribbon Bar. Then the select two lines at the lower left corner of your model, Selecting the line that represents the X+ direction first, then the Y+ line. The "Select View" dialogue box appears, and the X,Y, and Z directions should be correct. If not, cycle thu them so X+ is pionting right, Y+ is pointing toward the back of the machine, and Z+ is pointing toward the spindle. Select "OK", and the "New View" dialogue box appears. You can give the view a unique name, such as OP-2 (I also like adding a new toolpath group with the same name OP-2), change the origin, and select a work offset to be output. Check the box "Set as WCS" if you are manually flipping the part, leaving this unchecked should output A180.0 for a 4th axis.

If you have installed Mastercam, there are Documentation PDF's ready for you to explore. Go to the Windows Start button>All Programs>McamX>Documentation>Getting Started...

I've played around with it some... Do not change the scale of the screen size. I like to create a rectangle and record everything inside it with the rectangle "fit to screen". Also, be sure to unlock any buttons on the ribbon bar before you exit a function.

Being able to draw in Mastercam is one of it's strengths... Some ppl think it is a waste of tim for a programmer to be drawing, when he has paid good money for an enngineer/draftsman. Don't get discouraged.... If you can't draw it, you will likely have trouble putting a toolpath on it...

The HST is the new format for future toolpaths. If you look at the "peel mill" toolpath, you will see that there is room for more 2D toolpath types. You will be able to copy any toolpath and modify the type without having to bail out... Pretty cool. I'm sure most Mastercam training facilities would introduce this, but you might check with them first. Oh, the Surface High Speed Toolpath is for 3D surfaces.
