Hey Les,
i know that you tried to support G41/42 earlier and that you've given up because every control wants its own kind of entry-moves etc.
So that means it COULD be done, but for every control seperatly?
If so, how much would it cost me, if i would like to have G41/42 working for USBCNC?
Thank you very much and best regards,
Marc
G41 for USBCNC?

I can't really do this as an addon btu I'll take another look at the code and see if I can get it working. I do need to finish off V carving and some changes to the plasma path generation first.
One problem I came across was handling ramped cuts. In some cases the cutter needs to 'back up' after a ramped entry. Do you know of any way to implement this in G-code when using G41/G42? Most controllers will choke if you simple swap G41/G42 when you back up.

Imagine you have a simple straight line cut but you want to use ramping. The cutter will ramp down to depth but it then has to reverse direction to clean up the ramp and leave a square cut start. You wouldn't normally use G41/G42 on a straight line cut but the same applies if you are using a leadin and leadout or if you are using holding tabs.Spartan117 wrote:Sorry, i do not understand, what you mean?

What do you mean with "back up" ?
