Dust Collection hose support - episode 217

Pimp my Hose
Chip's back and he's not happy with the state of my dust collection hose. 
Can't say I blame him really and I had a good suggestion from a subscriber, (sorry I can't find his email to give proper credit)
Us a piece of pipe to support the hose and ensure it can't get a sharp bend in it. The sience of air flow in pipes is well beyond me but the basic thing to know is to have nice gentle bends and smooth inside surfaces. The hose I have is far from smooth inside but at least I can reduce the sharp corners.

The Result
Not reallly sure how I feel about the result so far.
It keeps the hose up and it looks tidier on camera but I could have done that by shortening the rope. It does eliminate the sharp bends in the hose so that is good and should improve air flow if only a little.
I am very interested in hearing what ideas you guys have and seeing if I can improve on the design or even abandon it and start something new.

This is the first on camera use of the vacuum table and is the sort of project it was made for. Holding thin material flat so it can be accurately cut. The new AutoZero Macro made cutting this project possible without cutting up the Tabletop.

UCCNC Macro upgrade
I also announced the new UCCNC AutoZero tool setting Macro from John Revill.
For those who are interersted it can be down loaded here

This brings the UCCNC version in line with the changes made to the Mach3 script earlier in the year. 
The addition of a Pre Touch test before the probing can begin will ensure that you have a working circuit so that the cutter will crash into the touch plate. This is particualy useful for those people who have to remember to clip a lead onto the cutter.

The macro has been provided in both Metric and Imperial flavours.
The new Macros have a built in touch test which must be performed before the AutoZero 
routing will start. After entering the material thickness offset you have 30 seconds to touch the 
touchplate to the cutter. When connection is detected the PC will beep and you have 2 seconds
to replace the plate on the table or stock surface.
2 seconds is longer than you think!
If a touch is not detected a time out will occur.
There is 1 parameter in the script that you must change, The touch plate thickness
If you have a touch plate with a switch in it the set "bool SwitchedTouchoff " to true
Everything else should be ok.

The Pre Touch test and beep can be disabled if desired but it is not recomended.

Thanks for watching and I'll see you on the next video.
