Andrew,
I cut much of the stuff to save bandwidth

Yes it is, even if it was made without a mill and from Home Depot
parts..!

Well I pushed him in a corner... and he got very defensive. If these
people just tell as it is, they would at least retain my respect...

Yes it is a four point mount and is solid as a rock.. I'll put that on
the TODO list and post it when ready...

I keep all their the brochures and other literature they send me... The
web site says very little about the mill...

And me..

$0.50 circuit board assembly. My
re-ybuilt version of the controller would be more cost effective to
produce and that's how prices are driven down...

[It doesn't look like it would fit in their box, though. How much would
these cost to make?]
Well in quantity they would cost MAXNC about $0.50 it's so simple. I
can post the design and board layout, you could even use the layout and
wire ot directly onto perf board and still come out with a neater
overall result.

Accepting poor quality with the excuse that it's cheap, is no excuse at
all.

[Every product made represents a balance between cost and quality. They
wanted to come up with a design that was simple to construct and would
meet
most people's needs, while coming in at a lower price-point than
anything
else on the market. If you asked, they should have told you that taking
heavy cuts in dense materials at slow speeds would be a problem. It is
best
suited for light cuts in light materials at high spindle speeds. ]

I understand that, but refusing to acknowledge there is a problem with
the design is silly. If they used the grey matter a little more, then
perhaps they could figure out a better and possibly cheaper solution, it
can still be done well... I still like the blue anodizing...

I just wish I had seen this list before I started into this venture, I'm
sure it would have saved me $$$$$

[I thought we liked learning experiences in this group? Just out of
curiousity, what would you do if you had it to do over again, start from
scratch? Save up for a Taig? ]

Well how about http://www.grifftek.com/controllers.htm Have a close
look at some of the workmanship in the wiring.. this is nice stuff..

[I like your modifications- have you shown them to MaxNC? Mind if I do?
Meanwhile, if I run into someone interested in a slightly used and
somewhat
modified MaxNC, should I send them to you? How much do you want for it?
]

Well that's like trading cars every year, I would end up more out of
pocket than ever. This $1295 mill has cost many 100's more...
I'll use it till it's a pain and then give it away..

Go ahead let MAXNC know, I already sent them a fax with my web page
address. Perhaps they will see something that can help them improve the
design... Make sure to tell them to read the very bottom of the first
CNC page where I say that this mill is about as much fun as a belly full
of pin worms.... !!
