We won't be able to ship any order until September 20th, 2021

Some weeks ago we finished moving our warehouse to Tortosa (Tarragona, Spain). We worked hard to open as soon as possible. We had to get the place ready for the products, install the laser, our saws, etc... We finally opened the store again but now we need some holidays.

We will be back on September 20th, 2021, so we will ship all the orders that same date.

The motor comes with four 30cm long cables connected which is compatible with the majority of electronic components, from RAMPS over Sanguinololu to Megatronics.

These NEMA 17 have a rated power consumption of only 5W, and are specially designed for use in conventional 3D printer Z axes, as a substitute for shaft couplers and threaded rods.

The main advantage of this system is that the special nut together with the lead screw prevent backslash, which leads to a better 3D printing quality since the thickness of the layers can be controlled with a high precision. At the same time, this permits a higher positioning speed on the Z axis.

The price is for one unit.
