Mach 3 PP

Problems and questions
1

the post processor Mach3.scpost includes in line 69:

post.Text (" G40 G90 G91.1\n F1\n")

we had a discussion in our forum because everybody modifies this line manually
since F1 causes an extremely slow movement to the first coordinate.

We are changing this to

post.Text (" G40 G90 G91.1\n F200\n")

which works fine.

Maybe you want to make this change in the original mach3 PP

That F1 shouldn’t make any difference because the first moves are at G0 not at feed rate. Simply changing the feed rate number is not as straightforward as it seems because you need to take the units into account (metric/inch).

Could you post a link to the discussion
