Program refuses to run Alarm in Z

[macdrum]

Hello and thanks for your help.

I have a Carve King and I create my g-code using Fusion 360 and run the code using python3. 

I wrote a simple boring program to create six holes into a 3/4" ply.  

I just ran some of my other programs and they all run fine.

Thank you for any input.

I have posted more information below.

Thank you again

I think the G28 is throwing your Z off.

N13 G28 G91 Z0

There was an update to Fusion 360 post processor. If you disabled G28 once you may have to go back and do it again. It's under "Safe Retracts"  I have it set to "Clearance Height"

[macdrum]

Bruce thank you for the update. I deleted G28 from the g code line and try to run the program. It didn't run at all and through an error.

I'm running python3 and I believe you helped me through the download and set up process. Thank you for that help. I like python a lot.



Thanks for you input
Michael

Setting to Clearance Heigth doesn't work.

Here two g code programs one works fine the other throws Z error. The first throws the error code. The second runs fine. Thank you for any input.

What error code are you seeing?

Try going through this info may be of some help
Setting Machining Heights:
help.autodesk.com/view/fusion360/ENU/?guid=GUID3EB12C22-C06B-4601-ABFE-7F1ECBABB9CE

I did find when the change was made to the GRBL post processor in Fusion 360:
Ver: 42683 3/9/2020 Added property to use clearance height instead of G28/G53 for safe retracts in several generic posts.

Hello

I have spent four days trying to drill or bore eight holes into a piece of plywood. I can't believe how difficult this is. I can run an operation on the same pice of ply but I can't create any holes. The machine head Z rises into the limit switch and stops. This does not happen with my other program.

I have tried different operations in Fusion 360 but get the same results.

Thank you again for any help

Michael

I have included the file from Fusion 360

jig for drum shell v60.f3d (190.31 KB)

[Bruce]

what is the other CAD/CAM program you have used to create your programs?
What G-Code sender are you using? bCNC is a Python based program.

Fusion 360 can take some time learning how to use it. I suggest going through some F360 tutorials on YouTube.

[macdrum]

I'm using python3

I have two operations for this 3/4" ply project. One works fine, the other hangs. Contour operation works fine, Pocket operation does not. 

I agree I'm still learning F360.

I'm also learning g code.

Here are the settings in python

Here's the g code for pocket operation.

[Bruce]

I loaded the code above into a simulator and all it does is drill 8 holes in a circle pattern.

[macdrum]

Thank you

I ran the program this morning and received this error message:

N84Y0.0025Y8.075

G-code motion target exceeds machine travel.

Machine position safely retained alarm may be unlocked.


So does this mean I'm working beyond the machines capabilities?

Thank you
Michael.    A student learning and enjoying every minute.

[macdrum]

After reading the error message, I relocated the hole pattern to within the tolerances of the machine and the program ran without any errors.

Thank you all for your input. I do appreciate allowing a novice like me to be a part of such seasoned people who are willing to offer their expertise. 
Thank you very much
Michael Carlito
