A bad contact with a motor wire can destroy a driver (they're well protected against shorts and overloads, but not against disconnection while powered on). Ferrules are the best, bare copper strands twisted together are good, soldered strands are bad. Some cables come with the individual strands tin-plated -- that's okay.

No, like these: https://www.inventables.com/technologie ... errule-kit (or their less expensive eBay brethern). (I presonally prefer uninsulated ferrules.)

Those ferrules are good -- check that they match the wire size. The tool you linked to is for crimping pins; the one for ferrules looks like this: http://www.amazon.com/dp/B00BS8IICA (some versions have six leaves rather than four: http://www.amazon.com/dp/B00H950AK4).

Ok so did a couple of upgrades today. Got a set of Aluminum Mounts for the Makita from Criznach. Since the mounts do not have the same clearance as Targs HDPE mounts the top of the Makita would hit the Stepper motor mount. Found a zero Clearance bracket design on here by Criznach and decided to take a wack at cutting out the bracket out of a piece of 1/8" aluminum flat stock I had laying around. That went OK Probably could have used a little better end mill but in the end it is just a temporary bracket right now anyway. We are still waiting for the Nema 23 Belt drive kits to get back in stock so we can get that put on. But in the mean time this will work quite well.

Also do a wack at designing a dust shoe. That has been pretty a load of trial and Error. More on the side of error. :-) First couple of attempts have pretty much been garabage. Good Idea on some bad process. Haveing the skirt getting sucked up in the vacuum port sucks..

and this is what we ended with..

Pun intended. Our shop we have a home made dust collection system set up. I will detail that out a bit more. Our Dust collection system is small but does a good job for us in the small space we have. The shop is roughly a 24 foot by 24 foot garage that has been converted to a wood working shop. We have it all insulated. For summer months we have a 13,000 BTU window AC keeps it quite nice in there. And for the Winter we have a wood Pellet stove. So anyway the dust collection is comprised of a Thein Baffle cyclone unit that dumps into a 5 gallon bucket. We build the cyclone with plans from Woodgears.ca. It is driven off of a Rigid shop Vac. We have a 2 1/2" piping installed down along our main bench and a port over head for benches in the center of garage and for the table saw.

Been busy with odds and ends.. Working on dust shoe all week and coming up with decent ways to mount Limit switches. Took a few ideas from here on line and mixed up in to ideas of my own.
all of my mounts are cut from .125 HDPE. Hardest part was setting up plates to strike the switches to trip them. I felt the locations of the switches seem work well. Though the switches are not stationary.

Very nice -- but were you aware that, if you choose the right type of microswitch, they fit directly on the motor plates? That's what the vertical slots are for.

Nope was not aware of that... but the mounting of the switches on the motor plates was the easy part. LOL

What size switches fit on the plate?
