I ran the auto-calibrate on X and Y until it was perfect.  I used the same tool as always, .125 2 flute end mill.

The 1" tabs that stick out on the end of the piece are coming in at .96 in the Y and the 3" slot at 3.03.  The project height comes in at 4.95. Something is bugging my Y axis. 

I have been using this for 7 years and have never had a problem. This just started with this project.

Any ideas would be appreciated.

That's what I figured Dave. I was just trying to streamline the process and thought there was some trick to doing it that was overlooked. I will just import the nc file like I was doing before and manually add the x,y coordinates. I still prefer to use the plug-in, but when we machine inconel, heat treated 316, and monel, those thread mills will wear rather quickly, hence the need for cutter comp at the machine. Thanks again!

Hi W7BCW

I was doing some concave slot features the other day for my indexer buttons, which my be similar to what you want to do. the trick here is to use use 2 d geometry and set the work plane to ZX.

If you draw a 3D object in SW (or other), then you can save it to STL format and import this STL in CB to machine the part with 3D machining operations ..

Just broke 3 end mills and two tool height setters.  That cheap pendant ain't so cheap anymore.  

The problem is simple enough.  It uses bubble switches for changing functions and one of the ones I use all the time to select step increment is just plane wore out.  I thought I was dailing in at .0001 and it moved 1.000.  

Didn't realize what was hapening the first time.  Second time the display on the pendant wasn't right.  Third end mill was just because the mill homing was off after the previous crash.  

Miraculously managed to save the part.  

Back to VistaCNC pendants I guess.  The worst I ever had my Vista pendant do was lose communication with the program.  Just have to keyboard jog when that happens.  


~~~~~~~~~~~~~  Time Lapse ~~~~~~~~~~~~~

Just ordered some VistCNC Pendants to replace them, and...   Cry    some new tool height setters.

HI Jim
I went to the site and generated the code for a M12 thread, the code is generated at 0,0 so you can't import it to cb and change the start point as it has already been set by the other program.
If you want to use that code, for say a thread at x = 50 y = 50 then you would move to that position and zero the x and y dro's. IF you want to use CB and want compensation then use the roughing clearance value to achieve the same result.
see pic.

I doubt that backlash is the only problem.
There may also be backlash, but as the error appears to increase with each pass something else is happening too.
Steppers loosing steps or workpiece moving would be my first ideas looking at your picture.
Try reducing the feeds by a large amount, 50% for example and mark the position of your workpiece on the table to see if it is moving.
That should give you an idea what is happening.

I have only pencil drawing and will upload it later but was thinking perhaps CamBam can't do what I
am thinking being only 2.5D and a 3D program like SolidWorks might be better for this.

Thanks for your help Dave.

do you have any image or 3D that show to whats look the finished object ? Maybe it's something to do with 3D machining (need a 3D object)

The lever pivots 1.5 inches away from the slot so that's why the arc is 1.5 inch radius so when the lever is
moved either side of center the inclines push the lever back to center because of pressure from a spring pushing
the steel ball into the slot.

I have looked at side profile and slope option but I need to do some more reading or find where someone has a better
explanation as to how that all works. I tried it out but maybe the way I have created the drawing and profile it won't work that way. I may have to try it using different geometry to understand how to set it up.

Thanks for the reply.
