Question Motors dont move

hey guys, I'm new to motionsim. Where should I start... I have a 2DOF with arduino uno r3 and 2 Hbridges in mode 2 and two wheelchair motors. The rig is completely built and I can start the motors in the SMC3 and they adjust themselves. But as soon as I go into simtools the problems start. I entered all the parameters according to the instructions, the firewall off, smc3 off, PC in English. (I will upload pictures). As soon as I want to test the output and press turn on and move the sliders, nothing happens. On the Arduino, L lights up and the RX but not the TX. In the SMC3, however, L and TX light up and RX only lights up when the motors start up. I've been stuck for 3 days now and can't find a solution to my problem.

Is there a discord where you can possibly have direct communication with a professional with know-how?

I hope u can help me. this is my darkest hour

thanks for the quick reply. Is it possible to use 500,000 bitspersec even though my com11 for Arduino says 115,200 bps? I'll test the whole thing on Monday morning and let you know if it worked.

Thanks again for your help. Your solution solved my problem. The mistake was that I translated the page into German and achse and axis looked the same. I noticed that one of the motors lags a little. Can I somehow adjust how directly they record the signals?

Hello guys, I have the same issue as you Peln... however I have done the same thing that I added this Output - [A<Axis1a>][B<Axis2a>]
and set BitsPerSec to 500000. Does not work for me... I am getting crazy out of it. I am using the same config as you Peln, however I have also the VNH5019 - (https://www.pololu.com/product/1451) - in both cases I can move the motors with pots and the SMC3 utils, where I just put the KP to 400 and pwr up to 255 and then the motors move. When I try the simtools and move the sliders for roll and pitch, they dont move. PLEASE HELP I am already desperate out of it. I can send pics of my setup as well...

Hello Youbuddy, many many thanks, ill try it when I get to it and let you know.

Hello Yobuddy. thanks, it worked for the wiper motors however I have now stronger motors, they are 24v, 550kw, 30A and I have the power source 24V, 600W but only 25A, the motors keep like shutting down, is that due to the power source?

Hello, noone is riding the sim, as I mounted the stronger motors, as I wrote before, the power source is only 25A and the motors are 30A... they are not grnd isolated, so I try this and put it on the frame, however I was thinking about the grnd on arduino, is that ok? anyway, ill try it first on the frame and also ill try another power source which will be at least 30A, because I have feeling it is causing the issue...
many thanks for your support mate...
