Good luck

It probably ( most likley) just brushes on the router. I have changed mine 3 or 4 times.it easy todo and cheap to replace . Could be a good choice for a backup router.

I may be able to help with a prototype. I have been building out of metal and sheet metal for many years and have a good understanding of what could be done. Can you send a rough sketch of what you...

Make sure that the bit is clean. I have had buildup before that will stop the connection to the zero plate

I think that we fried something on the input board on our PRT Alpha. I know this happened on another machine I own and I was able to change it to #4 instead of #3, but I cannot remember the process....

You can also grind the foam to shape bit its pretty messy

Draw a vector around the shape and when you calculate the toolpaths highlight the vectors. It will only machine between the vectors

The one with the dark head is a juvinile, it takes up to five years to get their white head and tail feathers. Looks like maybe they are looking for fish in the pond.
VERY COOL? I live in Minnesota...

Maybe jack is 3.1416......... days late intentionally?

I believe you can draw a circle around the perimeter of what you want to machine and whendoing the tool paths you need to highlight those circles. The toolpaths will be created inside those...

I agree water jet is fast and clean

You should set the bit to the actual size and re run the test. It looks to me like you will be with in machine tolerance.

The company I work for signs C oof C's on a daily basis for parts going on Millitary Vehicles.
This is just saying that you are building to the spec on the print.

I found a set of screw extractors at the local hardware store that would take out a 4-40 screw for about $20 they worked great. I dont have them here with me but Monday I could get you the name brand...

I would think, if you picked a section that had no undercuts, you could do a 2 rail sweep and then just machine that portion with the board layinf flat on the table. Otherwise it;s cut at angle...
