Brushless Gimbal Controller

[Stef Stuntpiloot]

Just tested it with 2kg payload on the rollaxis, works good after some changes in PiD D, ACC_weight and motor updatefreq

 

[RC FAN2]

video ?

 

[Stef Stuntpiloot]

I'll try to make one but please do not laugh, because i'm waiting for the mold for my actual gimbal I made a temporary one from balsa wood. Took me about 4 to 5 minutes so that gives you an idea how ugly it is



I'll have one online in 10 minutes

Ahw I cannot make a video, My balsa frame just collapsed under the pressure of 2x 6S8000 batteries AND a gopro

Do you mean you tested the 2kg on the roll axis with one motor type 4404? That's not bad, actually more than I expected.

Sorry to hear abot your collapsed testframe. Are you going to mold the gimbal with carbon fiber layers?

 

[Stef Stuntpiloot]

Thats right, On the horizontal arm It does need to be balanced quite good because it does not have that much spare power but it holds position really good. I Do use a 4S battery, 3S is not enough. When I touch the arm and press one side down it slowly gets back to level so that also works good. When I have my gimbal done I will post it here. Its designed to handle camera´s up to a 5Dmk2 body from canon plus a nice lens up to 600 grams in weight.

Is this usable for driving brushless?

It's for stepper motors, since it has only two phases as an output.
And you need to talk to it in a high level command language.
Nice chip, but not really suited for a simple 3-phase driver circuit.

Hey guys, just wanted to say hello and maybe help participate in the beta tests. Im gonna try to hand solder a control board here in the US.

Encontrei um problema, mas não faço idéia de como resolver.
Aparentemente parece na sincronização das fases, mas não é porque o motor corrige o erro.
O código está funcionando como Alexmos, porém com este bug.
Notem: quando movimenta lentamente, há um momento em que o motor dá um movimento a mais.

 

[germinbmxer]

is possible update PID settings with serial port?

 

[Lonestar78]

not yet. Update over Serial will be available in one of the next versions.
Or add it yourself and contribute. Its open source .-)

Wenn jemand eine GUI dazu schreibt , kümmere ich mich gern um die Serielle Kommunikation und das abspeicher der Parameter in den Eeprom .

 

[wareck]

I'm working on it...

 

[RC FAN2]

on a GUI ?
can you share with us the Protocoll ?
i will add the function in the Gimbal Controller Code ....

Controllerbox für Brushless Gimbal

Sehr geehrte FPV-Freunde,

das letzte Kunsstoffteil für das Gimbal ist soweit, es handelt sich um die Controllerbox.
Die Kunsstoffteile für das Gimbal gehen in den Druck.

Die CFK-Teile sind bereits alle gefräst, die CFK Rohre alle auf Länge geschnitten.

Demnächst gibt es ein Video und Fotos vom System.

RC FAN2,
your controller is work like as alexmos, but i see a problem.
why motor not run smotilly? is not linear.

 

[RC FAN2]

smooth enough ?

see on second video:
exactly 0:02 to 0:03 second....its a problem!
