you can see the 2 aluminium plates finished. thats here the best kind because the product is for sewage channal (i don't know the worfd, waste water under the street) for the roboter to repair the channel. it's a old tecnology we built 25 years ago and need repair-parts. so i don't want to optimize a process, i want to repair quick and dirty. but thanks for your idea.
by this problem i learned a lot about fc. it was my first time to get a g-code out and it was since 7 years my first time using my selfmade hsc-cutting machine with emc2.
so i'm happy
