rounding toolpath radial with mach 3

Post by sawmiller »

hi all,
working with my joes 4x4 4th axis which uses mach3 for the driver

the optimized raster and the raster left little tits all along the piece ( using 1/2 ball nose at 10% stepover ) they really did not work the way i thought they would.
rather than just going back and forth they would also sometimes rotate the piece while going back and forth

this by the way is using the Y to A PP

so i decided to try the radial.
heres the file produced by the pp
all it did is stutter from x 0 to 18 while the A axis did not move.... not what i wanted

i edited it and got it to work( spindle moves over, A axis rotates, repeat till done) with this file
what i think worked is i replaced the A-360 with A359... is the pp right and i need to fix something or is it wrong ?

yup, was the 360 rollover.
do NOT check this in the general config for mach 3 .
does not interpret Vectric's pp properly.
