Yes, there will be an example of a lineardeltakins configuration in the next release.

I believe the BeBoPr++ uses the same pins as the BeBoPr+ which is the same as the BeBoPr-Bridge, so hopefully one configuration will work with all of them, but I don't have details yet. As for the end positions, some things cannot be changed at runtime via HAL (apparently some really old stuff that pre-dates HAL and never got migrated to HAL signals/parameters). But you may be able to do what you want using G92 offsets. You should at least be able to use G92 to do a bit more testing between re-launches of LinuxCNC. -- Charles Steinkuehler char...@steinkuehler.net
