Dear Vicente,

I think you are most likely looking at two identical packages. The stepper 
driver is definitely the same Chinese brand (Wantai motors) and type, and I’d 
assume the  only difference between the packages is the power supply (48V in 
the Chinese package vs. 60V in the Spanish one).

I’ve also checked the price here in China (in Wantai’s local online shop), and 
it’s only slightly cheaper (1390RMB) than your ebay link.

I’ve asked a friend (experienced CNC geek) for his opinion about the product 
and let you know as soon as I get feedback.

The main argument for buying from the Spanish vendor would be the 
easier/cheaper handling of warranty issues. If you buy from China and happen to 
get faulty devices, it’s more expensive and troublesome to get the replacement. 
It’s a tradeoff between price and risk.

… oh, already got feedback while typing this. I’ll just copy and paste it here:

I suppose I can hook you two up later if you have more questions.

Hope it helps,

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 

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 


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 

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?
