perfect, it's always good to have the opinion of other people. What motors you
specifically recommend? I have guided by winding machine of USC College. They
use a Nema 34 motor.

guides, I will use a steel shaped "v" inverted 40 x 40 x 4 mm.

Hello,
I know two people who made a winding
machine, one of them sells carbon tubes for sail ships.
I am also thinking of it, but had no time
yet for it.
If you have no experience in cnc, either
machine construction and programming, then you will have a hard start, but it
is possible.
You will not need 8.2A steppers, small 3-4 A steppers will be
sufficient. You will need a slow but strong stepper as turning motor, the best
is with a transmission on it.
Also you will need 2 axes, one Z and one X-Axis, only Z is not enough. So 3
steppers, one big with transmission, and two smaller ones for the filament.
The Z and X-Axis need to be fast, so big large motors are wrong here.
Then you need long steel guides, THK and others make these. Since
precision is not needed, you can also use a steel ruler and make a slide with
ball bearings as a guide.
Check out nanotec, and use Leadshine stepper drivers, a Meanwell
48V power source, that is the czurrent standard in europe for smaller cnc
machines.
It will cost a bit, but that is material you can rely on.
Next problem you can think of is: How to get the tube from the core…
Not an easy task.
Here you find a german thread from one of these machines, a large
one for large carbon tubes.

Hi friends,
lately I am (among other projects) investigating the
possibility of creating a filament winding machine for the construction of our
carbon fiber tubes.
This machine has a CNC system. This machine will be
operated by the Linux CNC software.
I ask for help, to make use of your experience. I found
two internet providers complete kits.
The first gives me this: 380 €, shipping included.
2 PCS
Nema 34 Stepper Motor with 1600oz-in holding torque on 85BYGH450C-012,
2 PCS Stepper Driver with 8.2A DQ860MA
2 PC Power Supply for 350W,60VDC,
1 PC Breakout Board DB25
The second gives me this: 205 € and in the absence of
knowing the price of shipping.
http://www.ebay.com/itm/2-Axis-Nema-34-Step-Motor-1600oz-in-CNC-Control-Mill-/180656961021
The first is from Spain (I'm from Spain) and the second is
from China.
The shipping cost of the second provider will be above 100
€ (need confirmation).
Which of the two recommend?
Regarding the software, I do not know how to use. I will
start to study once the machine is in the process of manufacture. But is there
any volunteer who can offer online help, and even make some program?
Cheers
