Did you try to reconnect the FB (the green Button, as usual)?

use bricklink: new, USA, 28 $ item No. bb0960c01

Yes, I never found an explanation for that, should be here: https://docs.pybricks.com/en/stable/parameters/button.html but is not.

Indeed. Normaly: Rotate clockwise till motor stalls, save position A Rotate anti-clockwise till motor stalls, save position B Rotate clockwise to B-A In your case: just drop third command. You have to check if motor is still running, that's all. 1.) Start motor A 2.) Wait 0.2 seconds 3.) Wait till A = 0 4.) Stop Motor A 5.) Set angle of A to 0 Ps: my "gaming controller" was less than 20 € .....

Hi, don't know what version you are running, but 2.9 should still work? Older versions: Search for "Motor(port).control.limits....." and replace with "motor.obj.control.limits...." @ejayb , no I only have tacho motors and had not any problem, have a look: https://www.youtube.com/watch?v=UaNMkoPSUSA or https://www.youtube.com/watch?v=74n1VGK8jwE

I see! very interesting, and a nice solution.

Is there a specific reason why you run Pybricks on the hubs?

First, there is no Mindstorms any more Second, what would make it "Friends" specific? And Third: Why? April Fools' Day ?

Yes, true, I mixed that up with the tacho function, sorry.

Only the mentioned train motor and the 45303 can be regulated with the handsets. All others offer "on and off" only with handsets. Use pybricks, a smart device, a microcontroller or modify the cables.

Hello, Sorry, no, the links don't work any more, as it took too much effort to me to adapt the programs and description to the changes pybricks made.

Yes, if you have one "master " to connect the remote and then send data to other hubs.

Just use a Powered-up cable on pins 1+2 ("motor") for the relais and connect the cables 4 with 5 and 3 with 6 , that simulates a train-motor to the hub.

I know that, but that has nothing to do with the LEGO Mindstorms Software (which should be LABVIEW). You can use a dozen of laguages and packages on the EV3. like, Ptyhon, like C++, like Java.....

I think all the sensors have different modes (color, reclection, ambient light, distance) , therefore they might look different. Yes and no. The problem in most cases is the surface the tracks lay on.

Is it "labview"? Where do you find Micropython there?

No, there is need fror a specific folder. The normal OS "open File" dialog is used. Are the help fiels not included in you package?

File -> open project

normally the train is that quick that it flies out of the curve. I suppose you need a new motor .....

Hi, look from 1:00 to 1:30, the machine is much too slow. Can you easliy turn the axles of the motor and the others too?

Just use PU motors with tacho function. Extremly low speed, no gear at all needed , one medium linear motor, have a look: https://www.youtube.com/watch?v=UaNMkoPSUSA

You'll find problems running two L motors on one City Hub......

But they do something completly different, as they don't have any feedback (most of the PU motors have an implemented tacho and allow speed regulation via the software)

It is declared as "retired product" https://www.lego.com/en-us/product/simple-medium-linear-motor-45303

For a "smaller" locomotive they are suitable, one of them. As usual all infos can be found her: https://www.philohome.com/motors/motorcomp.htm I prefer the "medium linear motor" (88008) , as it offers much more features. Please note that the so called M-motor ("simple medium linear motor" 45303 ) is a long retired.
