LinuxCNC Paid Help

except that the error only occurs on my machine, but not the backplot Axis sim

linuxcnc.org/docs/devel/html/config/ini-...l#gcode:ini-features

CENTER_ARC_RADIUS_TOLERANCE_INCH = n Default 0.00005

CENTER_ARC_RADIUS_TOLERANCE_MM = n Default 0.00127

try playing with these setting, I have them set on my machine. Its been a while since Ive had that error but this is one of the things I did, I hope it actually does something. The other thing I did was tighten the arc tolerance when doing helical arcs, that was where I mostly had the issue.

Where are those settings located ?

In your ini file under the relevant section heading. It may help to read the whole page that was linked.

/your_home_directorylinuxcnc/configs/name_of_your_config/

4 posts up I put up my configs,

changing the precision value in the prost processor for fusion 360 seems to have resolved the radius arc errors.

Time to email Autodesk

You asked where those settings where located.

I just replied where they were located.

Instead of just (insert bad words here) whinging & complaining, how about a "thanks mate". Seriously if this is the way you treat people volunteering help I'd really hate to see how you would treat someone you paid for for help.

Sometimes the setting need to be added to the section
the link I provided was for the ini file under the rs274 section, so just add them in. it probably has less to do with autodesk and more to do with linuxcnc having a tight default tolerance

CENTER_ARC_RADIUS_TOLERANCE_INCH = n Default 0.00005
CENTER_ARC_RADIUS_TOLERANCE_MM = n Default 0.00127

I will assume this means the arc tolerance is set to .00005" for imperial, most of the time i have my default arc tolerance for roughing set to .001" in mastercam. So see if gradually increasing that number makes a difference

Yeah i was searching inside the  ini files, and I was wondering if this was a case of needing to add a few lines to it.

Thank you, changing the post processor seems to maybe be a better fix however. I will be retrofitting 3 more hurcos for production work in the home shop shortly. 

The tool changer looks to be daunting potentially.
