5-axis (head-head) router alignment/comp document.

[DavidJackson]

I wrote up some reas. thorougher/thought out documentation for alignment of 5 axis head-head routers after tearing my hair out too many times at 4am with the factory supplied info and 4x floppy bendy machines (....thermwood....) Document covers, rotary compensation which thermwood were not forthcoming with,

and is(was!) a huge sorepoint. Otherwise it is pretty generic bar a few axis

labels and angles.

 

Posting it here as it may be useful in the future to somebody in a similar position, and also with a bit

of luck somebody will peer-review it. (or add to it the stuff that I took for granted/thought too obvious to write down)

 

(Or otherwise, constructive criticism welcome.)

 

Edit - Updated 13Mar12 - Clear C-Marker offsets before doing rotary comp.

Thermwood documentation leaves lots to be desired.

I'm going to give this to the guys.

thanks

Dude. You're my new hero. This is exactly what I was looking for (I've been calling and emailing Thermwood but they've not been very helpful...)

 

The only part of your document that I'm having trouble with is page 3. I can't quite wrap my head around what's happening there. Any chance you could help me figure it out?

 

Also (and please don't take this the wrong way, I just figure you might like to know) the plural of 'axis' is 'axes'.

 

Even if you don't get back to me, I'm still extremely grateful to you for making this available. Like you said, the manuals are pretty damn useless.

 

Cheers!!

if you are referring to step 2 page, it looks to be a method for setting perpendicularity of B axis rotation to Z axis travel.

I figured it out (was embarrassingly obvious when I looked at it this morning, guess I needed some sleep...), but thanks for the reply!

David Excellent work.

Got an old CMS 5 axis that I'm slowly taking over programming for. Thanks for the document, CMS has a very similar document, but is a little vague in certain areas. Your document patches it up nicely!
