Failure to cut

[Adrian]

You can't upload STL's without zipping them first. Copyright permitting people really need to see the Aspire (CRV3D) file to be able to help as that will have all the settings.

The cut file saved from the toolpaths would do to check feed rates etc if you can't attach the Aspire file. You would need to zip it or rename as a txt file to attach it though.

Found the CRV3d file, this time its to large for up load LOL The Gods are after me !

[Joe&Elaine]

I did compress the file, tried to upload/drag drop into reply. Got a " to large file" reply awesome

Ok, then you need to put it into something like DropBox or OneDrive, GoogleDrive, etc and share the link.

I would suggest you do that with the cnc file not the crv3d since that model may well be copyrighted.

Surprising what us oldsters know about cnc code!!!

Please check the feedrate on the cutter. Make sure there is a reasonable feedrate programmed.

[gkas]

Also, are you homing XYZ after EVERY power on of your CNC? That is how everything calibrates.

[Joe&Elaine]

Yes I do home the machine every time. Just tried to upload just the rough in portion of the file, also zipped it. To large again. Off to plan X-Y- or Z.

[Adrian]

Just attach the toolpath (gcode) file. A lot can be sorted out from that.

[Leo]

Agreed with Adrian - post the G-code at least the first 50 - 100 lines and then the last 50 - 100 lines.

Some of old timers know how to read that stuff.

Adrian asked to have different file run. That was said to have been done. Adrian then asked if that run was successful. That was never answered.

Did that other project run uccessfully or did it also have a problem.

I followed the procedure, loaded into an Axiom machine. The cutter comes down ready to cut and will not go to the material surface to cut.

I’m not entirely sure what “the procedure” is you are talking about here but be that as it may I have a thought:

Was the Aspire file created in inches? Did you save the gcode for loading into the Axiom machine using an inch based process or a milimeter based one? Or perhaps a milimeter based Aspire file and an inch based post-processor?

[Leo]

This really sounds like a no feedrate programmed.

Everything up to that point in the program is G0. The G0 is a default and will definatelty move. When the cutter is ready to cut there is a G1 X... Y.... Z... and F(something)

If the F has a .001 or something less than 1 is will do just that --- STOP as the control will be waiting for a feedrate, but there is none to be had.

I have seen this quite often.

I asked the question several posts back - but go no answer.

[Joe&Elaine]

Hello, New plan, got a different STL file that is much smaller. I went thru same procedure as the Marine logo and got the same result. So here is the rough cut file. Hopefully I / We can find out what I am doing wrong or not doing correct.
Thanks Again for the help
Sincerely
Joe

Opps-------- New plan, was not familiar with dropbox etc. BUT I will do just that today.

I could not see anything wrong in your file with the exception of no zero plane. But that would not cause what you are seeing. You should add one as a rule when doing 3D work for a bunch of reasons.

If you are using the Axiom post the one I have shows that it produces metric output.

I typically work in one unit or the other and do not mix them, so maybe some of the other good folks here can steer you in a direction that helps.

[Adrian]

Can't see anything in that file that would directly cause the problem you said about in your first post.

There's a couple of things to bear in mind though for when you do get it cutting. First the stepover of the roughing pass is set to 10%, that's more typical for a finishing pass. 40% is more usual for a roughing pass. On your finishing pass the title of the tool is 0.0625" but the actual tool you've defined is 0.125". You're using a ball nose for the profile cut out. You can do that but again it's more usual to use an end mill for that.

Have you ever had the machine cutting from toolpaths generated from Aspire? Which post processor are you selecting?

The toolpath file would be really useful as it looks more like an issue with the post processor selection and/or machine setup than the Aspire end of things.
