How can I connect a second servo MG995?

Hello folks,
what if I want to control 2 servos independently? Do I need a level converter? Can you recommend a level converter to me, please?

P.S. How can I correct the heading? Servero ->Servo

Thank you guys, I will try the solution on the weekend.

Hello folks,
I have a problem with a servo M995. I just can't get it to work. I've already searched the forum for the problem:

Wiki Using servos and controlling unused IO pins

-> duet-2-on-rrf3-servos-not-working
-> servos-not-working-correctly
->help-configuring-rc-servo-for-spindle

Unfortunately I didn't get any further.

wiring :
I have a 230V AC to 24V DC /15A power supply for the board and a separate supply, 230V AC to 5V DC Mean Well IRM-30-5ST with 6 amps, for the servo. The servo is connected as follows:

RED, PLUS SERVO -> +V0 Meean Well
BLACK, MINUS SERVO -> -V0 Mean Well and GND on io.6
ORANGE, SIGNAL -> io6.out

I have also tried:
BLACK, MINUS SERVO -> -V0 Mean Well and Duet 3 Mainboard, Power In GND

Nothing happens with g-code command M280 P1 S50
But if I take the servo with a tester and a separate laboratory power supply it moves as it should. It was also tested whether 5v come out of the meanwell power supply. It is ok.

Can someone help me, please?

Thanks for the reply guys, I think it will be a Duet 3.

Hello David and Tony,
I would like to buy the Duet 2 Ethernet. I have the following motors to choose from:

Trinamic NEMA23 QSH5718-56-28-126, RatedPhase Current 2,8A and Holding Torque 126Ncm, Phase Resistance 0,9 Ω, Phase Inductance 2,5 mH : Link Datasheet

SANYO DENKI NEMA23 103H7126-5840; RatedPhase Current 3A and Holding Torque 160Ncm, Phase Resistance 0,99 Ω, Phase Inductance 4 mH: Link Datasheet page 54

ACT MOTOR NEMA23 23HS6620; RatedPhase Current 2A and Holding Torque 126Ncm, Phase Resistance1,8 Ω, Phase Inductance 2,5 mH: on ebay

I need around 1,2 Nm of torque for my large 3d printer. Could I use Duet 2 for this? Do i have to cool the drives with a fan?

Thanks in advance

Florian
