biesse rover 316 retrofit

gcode is from solidcam. *.nc extension ,arc has I an d J incremental mode.

Here is my Ini file, there is no ARC_BLEND_ENABLE =`` in TRAJ section. should I add it?

The default setting is ARC_BLEND_ENABLE = 1, so if it is not present that is what it is. If you want to try the old planner add the line and set it to 0. It won't hurt anything and if you want to switch back to standard set it to 1.  Remember you do have to shut down and restart Linuxcnc for configuration changes to take effect.

hal pins can alter the settings:

> ini.traj_arc_blend_enable
> Allows adjustment of [TRAJ]ARC_BLEND_ENABLE

Ref:
$ man milltask
linuxcnc.org/docs/2.8/html/man/man1/milltask.1.html

See NOTES for restrictions

 

unfortunately changing arc_blend_enable = 0 or 1 has no effect, feedrate is drastically reduced at the entrance and exit of the curve. I increased the engine acceleration to 600 the same.

I insert arc_blend_enable = 0 just in ini file..ahve to check what is in hal?

Looks like something in gcode is causing that, so can you use Inkscape to generate a simple shape using built in extensions>gcodetools>path to gcode.

i am using just solidcam for this i am working on wood chairs.. i can try simple circles gcode from aspire to export as ngc not nc as is in solidcam. i take a look in hal pins it’s now false in arc blend enable but the same situation with exact stop at arcs. Will check with gcode exported as ngc with same contour as in solidcam. but just to check.. in practice i must use solidcam for toolpaths.thank you

Ok, try adding
G64 P0.5
at the top of the gcode file, if 0.5mm of tolerance is OK, try also lower values like 0.3 or 0.1, see if that helps.

yes, I added that too, although I think P0.1, I'm not at the machine now, but I'll see tomorrow, maybe a higher value will help

I agree, it looks like it might possibly be something in the g-code. Could you post a bit of the problem g-code that exhibits the problem for closer inspection.

Unfortunately I'm not familiar with Solidworks, so I may not be much help adjusting its settings to better optimize it's output, but we may be able to make general suggestions.
