Hello
Finally I got a few pieces from China and Italy and I’m starting the assembly, in the meantime I’m printing all the parts of the project with the 3D printer Anet A8 with PET-G filament, very very resistant to bad weather and high temperatures. The white PETG filament of the E-SUN is truly exceptional and the worm gear is printed very well

Work in progress and little tricks
If L shape hidden corner was too long, you can mount in rear slot like my pictures
Boom and Ball bearings are 40mm diamater so the bearing does not want to enter and flow on the boom. A trick is to file the pole surface with abrasive paper until the bearing enters and flows. With very fine paper, you can also polish the pole to make it slide.

The rotor is almost completely assembled, I had some problems in the worm gear because the 3D prints did not come well, so they did not turn well in the boom gear. I have therefore modified the print settings:
ANET A8 printer
PETG material, temperature 230 degrees, heated bed 70, cooling fans switched on at 60 percent, layer 0.2. The worm gear came perfect, and now it runs very well in the boom gear.
Agis and Team Satnogs gave me a great gift, sending me all the necessaries for the DC motor version. The PCB is really fantastic and the engineering design is spectacular.
I thank all the Team and in particular Agis for giving me this opportunity.
… see you soon with the rotor tests

UPDATE 18 OCT 2018
Yeah.
Now the rotator is finish.
It’s fantastic system engeenering
Now it’s being tested, but from the first tests it works great.
I thank AGIS and the Team Satnogs for this fantastic project.
I have taken care of the electrical part with regard to the shielding for disturbances caused by the drivers of the steppers placing at the beginning and end of the cables of the ferrite cores because in the previous version (V.2 rotator) I had many problems of noise caused by the drivers a4988
Soon a video will follow with the tests of the antennas and of the tracking system

Nice build. I like the cable clips you’ve got there. Where did you get them from?
Ok, didn’t think they would be printed but it makes sense
yes,you can print it. It takes about 3 min for 1 pieces

Bonjour,
Belle réalisation
Hello, beautiful achievement, I built exactly the same configuration, could you give me the reference belt gt2 thank you in advance.
Rémy.
Thank You Remy.
Belt is 158 mm like classic stepper version.

…And? …Did it work!? Lol…
Any observations? Tips? Hints? I plan on using the exact same dish as yours, I will be building another antenna as well.
Love the pics, looks like a nice spot!

Hi.
Rotators working good!
The only things is that for a Parabolic grid antenna (2.4 Ghz) you need a strong rotator like a DC motors version or this 5.18 stepper motor version because that grid antenna is heavy and rotator can lose position on elevation when stepper motor is off power.
Actually I use rotators for Noaa Satellites and Meteor and also I have tested rotators on february when ISS transmitted sstv images, with my new “3D printed arrow” antenna I received it perfectly on the whole passage, without problems of “MERIDIAN FLIP” given the last correction to the firmware

Hello iz5rzr,
Breathtaking your realization.
Really beautiful photos of the rotator V 3.0.1
I make about the same AZ/EL rotor.
I use a QFH that I made to track les NOAA and Météor.
I want to change antenna.
You’re using a new “3D pinted arrow” antenna, which I’m very interested in.
I’m looking for STL files to build it, to use it on the rotor.
What do you advise me ?
Thank you for your reply

Hello.
Send me an e-mail, I will transmit .stl files or you can download directly by Tysonpower.de, the designer of that kind of antenna

Hello iz5rzr,
Thank you,
Hi Max,
did you try to balance the parabloic grid with a counterweight like this?
Bye
