Hi there,

New Member, NE VIC, semi retired.

Thought I'd build an Engraver/Mill, probably going about it all wrong, but I
don't care. At least it will keep me off the streets for at least 15 minutes.
I'm into recycling, if you can get it for free or little cost why waste money ?
Have around 60% of the parts for an A3 or slightly larger table 2.5 - 3D unit.
Latest aqusition a cheap Chinese 4 axis controller and using Mach3.

After a week or so of testing (lack of or misinformation supplied from China)
I have the board fully functioning on Mach3 and calibrated my motors.
I also knocked up an X, Y, Z, axis + Spindle, DB-15 Port Remote Controller.

20mm linear base rails are next on the list-
Meanwhile I'll have a coffee and check out the wallpaper in here, huge forum !

Hi Kung Fu,

I have a Scorpion Brushless Outrunner RC type motor it's a 3032-#12 coil.
It's the slowest of the 3032 range the #8 or #10 coil may have been a better
chioce but this one was cheap @ nearly 1/2 price (Old Stock).
I don't have the ESC yet, saving up for that one.
And I will run the motor into a cut down 8mm HITACHI Router Spindle I
scrounged from a local Motor/Tool repairer, Did I mention I'm a tightwad ~ ;o)

I don't really feel like listening to a screaming 240V AC Router or Trimmer motor while I'm working away.

If my version fails I think I'll save up for one of those 1.5 kW or 2 kW all in
one water cooled Spindle/Motors, they are pretty much what my home grown
version will be from the look of things, mine will be air cooled.

The Axis motors I have are Recycled HP Printer motors, they're the page or
paper transport motors (PM55L-048-HP69) You have to cut the Common
Coil links on the connector PCB then run them as Bipolars, a one minute modification.
They are a 7.5 Deg motor, 48 Stp/Rev but I have their 6:1 ratio matching
steel reduction gear to make them 288 Step/Rev. Geared the motors are
quite strong, ever had a tug-of-war with misaligned page on an old HP printer ?
They draw around 1 Amp or so @ idle, less while stepping. And they do
get qiute warm (18V to 22V) so I may have to include an idle power
reduction circuit on the output of my 4 axis (China) Driver board.
I was given a heap of old HP Printers, so the price was right and I have plenty
of spares to keep me giong.
