Re: LinuxCNC and Path blending tolerance

Ok, I will set up my machine correctly. Just thought that I can set up this in G code. I edited feed for Z axis by Hand. My bad :oops:

Will re check my machine settings.

Re: LinuxCNC and Path blending tolerance

G64 was a preamble. Two G0 moves one after another was generated by Freecad Linux CNC postprocessor. This caused a "crash". Its not so uncommon to have a different feeds on Z axis and XY axis. And setting rapid move to lowest possible value for axis that dont travel as much as XY is waste of time. M...

Re: LinuxCNC and Path blending tolerance

This solution didnt work for me. :?

Code: Select all

G64 P0.1
G0 Z10 F50
G0 X0 Y0 F500
Different feed rates on Z axis and XY axis produced the same result like when not using G64.

Or maybe I'm just using G64 wrong?

Re: LinuxCNC and Path blending tolerance

The problem was that LinuxCNC is blending the G0 retraction move with the G0 rapid to the next hole I tried to describe the exact same problem. Freecad postprocessor for Linux CNC generates G0 codes one after another, but Linux CNC will blend this two G0 g-codes in to one. https://m.youtube.com/wat...

Re: LinuxCNC and Path blending tolerance

Well I noticed this today also :? Fortunately on a test piece made from foam ;)

Code: Select all

G0 Z10 F10
G0 X10 F100
Will blend to:

Code: Select all

G0 X10 Z10 F100
But G1,2,3 G codes are not blended.

So now Im not setting any feeds in FC, and then find&replece G1 -> G1 Fxxx, and then G0 to G1 Fyyy etc.

Re: PCB design & machining

I think that some people use kicad and export to dxf, than import dxf to Freecad? And really most dont mill all that surface, just router aroud traces, its also beneficial to remove noises from circuit with all that big gnd area.
