Time to machine some aluminum clamps for a nice vise. To be used on the palet of my Intelys C3000. First time I am using 3D printing to check the part before wasting material and time with CNC milling: very useful, let me fix some design flaws before machining!
A good friend of mine gave me an Inca 260 bandsaw. Unfortunately, the original miter gage has been lost. Found a good design on thingiverse (www.thingiverse.com/thing:505852) that I have tuned for this machine.
I have experienced poor cutting speed with complex curves. The feedrate was not constant, even with G64 command.
After googleing few hours, I found a clue: LinuxCNC needs a tolerance parameter to be able to blend complex curves with true constant feedrate. Now I use “G64 P0.01” which gives 0.01 mm allowed error for the tool path. With this feature I have decrease the machine time from 3 hours down to 40 min for the same job, 1/4 ratio !
Below a video showing my machine cutting POMC at 700 mm/min feedrate.
