Unable to see tool path after loading new G-code file?
« on: February 03, 2014, 11:10:14 AM »
Hello,

I just "wrote" a new engraving program with morning using BobCAM V24 It ran perfectly in the BobCAM simulator. I then opened the G code in Mach 3 on our CNC router's computer. The engraving is straight forward, on a 9" x 9" square. But I cannot see the artwork in the Mach 3's Tool Path window, on the right hand side of the monitor? There is a tiny little green dot that you can not zoom up to, no matter how you try? Any ideas? The machine was working fine last week.

I did try loading another file that has been used before, and it opened in the tool path window, just fine?
Thanks,

Cismontguy

Check the program limits to see if the engraving is far away from the origin.

Hello,

I am not sure what you mean, by limits?

The 9"x 9" rectangle is at 0,0 for the lower right hand corner of the X,Y axis in BobCAM.

Also, do you get an error message in Mach3's status line?  Sounds like maybe a problem with the BobCAM gcode.

Go to the Toolpath page, and see what the X any Min and Max values are in the upper right part of the screen.

Thanks for the replies!

OK the Program Limits screen shown on the Tool Path page of Mach 3 are : X range +0.00 +15.540 /  Y range +0.00 and +7.360   which are well within the working range of my CNC router area of movement.

I decided to take a chance and just run the program and it ran just fine but for some drawing detail errors that became apparent when the tool cut the sample materal, but still no tool path illustration shown in Mach 3?

Just to answer the other question, Mach 3 is not showing any error messages on loading the file and creating the tool path.

Do you have the toolpath turned off?

Hello,

Yes, were have a fully licensed copy of both BobCAM and Mach 3. Yes the Tool Path function is turned on . I can see it on other CNC programs I have loaded this morning to make double sure something in the settings has not been changed between today and last week.
