General Mach Discussion / Re: Mastercam X5

When you say it didn’t work properly, did you mean

1.It was the wrong size
You say it was 100 x 100mm, but the dimensions in the program indicate 200 x 200
Your geometry is wrong, fix the geometry.

2.It was feeding too slowly
Line  N170  F3.6 is 3.6 mm per minute
It would take 55 minutes to go 200 mm
The feedrate is set on the “TOOL” page in Mastercam X5

3.The depth is wrong
You say you went 10 mm deep, but line N160 makes a rapid move to Z-15. and line N170 feeds to Z-20.
The depth and feed plane are set on the “LINKING PARAMETERS” page in Mastercam X5

4.You wanted the tool to be centered on the lines
It looks like cutter compensation (handled in the computer by Mastercam) is on. That shifts the tool ½ the diameter so the cut will leave the line.
Compensation type and direction are set on the “CUT PARAMETERS” page in Mastercam X5

5. You didn't want to use tool number 219
The tool number can be set on the "TOOL" page in Mastercam X5

Let me know if it's something different that's not right, but I don't think there is anything wrong with the post processor


Nice job on the clocks and video. It was very enjoyable watching.
Part of the fun is to catch a glimpse of some ones shop and machines.
I missed the CNC, was it in there?

First paragraph.
I agree with you, but what if your tool is the correct size and run out is acceptable. Both inside and out side would be small.

Second paragraph.
This will work if your backlash has already been taken out by first moving toward the indicator.
Try moving away from the indicator then slide the indicator into position then move away again then back.
This way the backlash will show itself.

Third paragraph.
A 1 inch travel dial indicator or even dial calipers can be used, but I think that backlash is probably the problem.

Best of luck, you have to admit this is fun, even with the minor problems.

If you cut a square and the inside is small so will be the outside.
With your dial indicator move a distance you can read on the indicator, say .02 then again in the same direction, then again in the opposite direction.
This will tell you what your backlash is. If it's not backlash check that the amount you move is accurate.

M98 P10 jumps to O10 in your program, but remembers where it came from.
M99 sends it back from the jump location.
M30 ends the file.

You need an M30 before the subprogram so Mach will stop reading (after line N22)

With no M30 the file reads directly through the sub until it sees the M99, but has no place to return to.

Hi Bob,

I've never checked the accuracy, but if you go to Tools/Options/Workspace/Edit you can change the precision.

If you check it out let us know if it really makes a difference.

Give this a try.

X and Y zero at lower left corner.
Z tool offset on the surface, Z+.100 for clearance
F10. for plunge and contour (you may want to slow down)
1.48 wide 1.49 high

Special thanks to BR549 for the coloring page.

Your real close.
Line N85 turns on cutter comp then you go to your sub. After the sub is finished you move to your next starting point and the cutter is compensated going in that direction. You need the compensation in the correct direction.
You could add
before your Z0 move.

I think you can double click on "None" for image path to allow a different bitmap.

You say "it has happened a couple of times".
Does that mean that some times it's OK?
If you run without a part or just look at the graphics are things OK after the move into the part?
