GIRO - TEVO Tarantula / Y-Axis Motor Mount
This Nema17 stepper motor bracket was designed to improve the Y-Axis movement by reducing the friction of the idlers due to the fact that if you want to tension your system properly then you will get a deformed acrylic bracket over time. The overworked Y-Axis bracket of mine uses a 40 teeth (40T) made out of aluminium and should not be printed. I noticed that if you print the pulley you might get a misalignment of the GT2 belt or the pulley is not sticking to the motor shaft and moves across it. The 40T pulley can be bought on several websites. The 40T pulley should have the following specifications.
- 40 teeth
- 5mm bore
- specificly for 6mm wide GT2 belts
They look like the one in the picture below.
This design is available in two versions. It depends on which side you mounted the stepper motor on your printer. Just take a closer look on the files. They are declared with the subcontext right and left to actually make sure that everyone receives the bracket he / she needs. You will also need to recalibrate your Y-Axis. Read the Additional Information section for further information.
This design is an addition to my 608 ball bearing Y-Axis idler which is called GIRO - TEVO Tarantula / 608 Ball Bearing Y-Axis Idler.
You will need additional screws and washers for the mounting of the idler. The needed parts are mentioned below.
Additional screws and washers
2x M3x35 Screw
2x M3x10 Screw (You may use the original screws of the TEVO Tarantula. They are already mounted on the original acrylic bracket.)
4x M3 Washer
6x M4x10 Screw
6x M4 Washer
This was the first intended design with a 40 teeth (40T) pulley and a first bracket prototype.
I would recommend to use at least 3 perimeters. Print with a lower speed, for example 30 mm/s, to get a more accurate printing. I recommend to print everything with at least 50% Infill.
Let me begin with the fact that you will need to recalibrate your Y-Axis. You will need to recalibrate the Y-Axis steps. I needed to reduce mine from 80 to 38.8 steps per mm. I would suggest to start with a value of 40 and then use a ruler to see if it moves 100mm correctly in Y-Axis direction.
Let me know if there are any kind of problems with the motor mount. I will try to help and if neccessary correct the designs. I appreciate any kind of feedback to these mountings.
If you like my work and find it really usefull then I would be very happy if you give me a small tip as an appreciation for my work. For all of you who gave me a tip.
