Gary thanks. I've got a vague inkling that those who know the topic better than me see a lot of value in ballscrews
That may be something for next year, I'm wanting to get a set of servo's for the mount I'm working on sometime while the aussie $ is still good.
I've not fitted the limit switches yet and had not thought about optical but that does make sense. I'm using the soft limit's but want the physical limit switches for a backup to soft limit's
Today's project was a drain tray and backboard. Still a bit to go with it (eg a drain) but the main structure is in place with some ugly welds in the corners. It's done in 1.6mm aluminum tread plate with some big chunks welded in to bolt the mill down to. I'll put some rails underneath as well. The electronics will go in behind the backing board. No photo's yet sorry.
I had a play with some cad stuff today, I have a copy of DraftSight and I downloaded a converter to output g-code. I've still got to play with that some more to work out how to create the right properties on a drawing to make the difference between a thin line and a hole or pocket.
