I have built a bunch of machines and configured even more... but I don't recall having this issue before.If I run the G-Code normally... it is rounding the corners... taking a shortcut. If I run the code in step mode, the cuts are perfect. 


I've built a bunch of machines and configured even more... I don't think I ever had this happen before. I'm going to head to the shop to see if I can figure it out. I've attached the HAL and INI files if you have suggestions.

Thanks,
Jerry

Well... it looks like I owe you at least a cup of coffee Tommylight!

I wonder how that got set differently????

Now I know... I'm updating my POST PROCESSOR for Aspire to include G61 in the header.

For those following this post...

- G61 - Exact path mode, movement exactly as programmed. Moves will slow or stop as needed to reach every programmed point.

-G61.1 - Exact stop mode, movement will stop at the end of each programmed segment.

- G64 P0.015 (set path following to be within 0.015 of the actual path) This actually does much more, you would need to read the section.

Thanks for a QUICK FIX... I thought I was going to be in the shop for hours figuring it out!!!

You can also add that to the ini file, it saves the trouble of entering that in MDI if you stop a running program and continue with "run from here". Here is a snippet from one of my configs

[RS274NGC]
RS274NGC_STARTUP_CODE = G21 G40 G90 G94 G97 G64 P0.025
Adjust to your requirements, this is for a metric machine.

That is useful... I didn't know you could specify things like that in the INI file.

I'll do that, I also run a Metric machine... my YouTube videos go worldwide... and more people use metric than not. Besides... I like the system better anyway.

THANKS!
