[QUELAB CNC] Fwd: [Members] Quelab Interest in a MaslowCNC?

[Adric]

So,  there was some discussion about this on the Members list, but ive seen
nothing after it was suggested by some to possibly move it to cnc at quelab.net
but i had not seen anything, (i just assumed i had left the list sometime,
 but no.  i see im still on it.

so, has the interest waned? Did the interested parties not get signed onto
this list?

Hi All



I am sorry if this isn’t the right mailing list to use…I’m still relatively
new to Quelab.



I am interested in building a CNC Router called a Maslow (see
http://www.maslowcnc.com/)and wanted to know:



a)      If anybody was interested in helping out?

b)      If there was interest and space for keeping it in the Quelab
woodshop and making it available to the Quelab membership? (Especially
since a large router is #2 on the Large Equipment Needs/Wants List).



The Maslow is an open source 4’ x 8’ capable CNC router.  It is implemented
upright, like a hanging plotter rather than lying flat (horizontal) like a
Shopbot.  They claim it has accuracy to 1/64” (0.4 mm) or better.  It is
not quite in the same class as a Shopbot, since it is slower and less
accurate, but good enough for my needs to make some plywood furniture
(i.e.,  www.opendesk.cc and http://atfab.co/ ) and can be built for under
$500 (including the $160 router Home Depot/Ridgid router) versus $8000+ for
a more conventional CNC router.



Here are the specs from the Maslow website:



Work Space: 4' X 8' *

Encoder Resolution: 8148 steps/rev

Repeatability: +- 1/64th inch (.4 mm) or better

Max feed rate 48 inches/minute

AC Voltage: 110-250 volts

DC Voltage: 12 volts

Connection: USB

OS for Software: Mac, Windows, Linux

Size: H: 6' 8" W: 10' D: 1' 7"



*The work space is defined by the length of the two #25 roller chains so it
can be easily enlarged or made smaller by adding or removing links from the
chains.



It was a Kickstarter project, but they closed the sales on their Maslow
kits and aren’t accepting new order until maybe September.  Since I don’t
want that long, I am going to try to implement myself with the information
available…and maybe make some upgrades in the process.  For example, the
baseline design uses an Arduino for control and the limited computational
capabilities of the Arduino seems to be one of the factors in the
relatively slow cutting speed.  I am thinking of using a Raspberry Pi
instead of the Arduino and hope that will allow it to run at a faster
speed.  If anybody has additional suggestions, I would be happy to have
them.



Thanks.



Regards



Michael
