Hello. I didn't connect the servo with the yellow handle physically. I place a Lego Technic Bush (https://www.bricklink.com/v2/catalog/catalogitem.page?P=3713#T=C) on the yellow handle pin to make it larger and the servo push it. You can see it in detail in this video https://www.youtube.com/watch?v=_1XNC5YFI90The housing for the servo is make with bricks and plates.

Hello. I put a Lego Technic bush (https://www.bricklink.com/v2/catalog/catalogitem.page?P=3713#T=C) on the handle to make it bigger. Then the servo pushes it when it turns.

Hello . Use the GitHub file instead of the code on the Instructable (the link is near the code). On the GitHub Repositorie is a file with all the code and the library needed.

Hello. I don't have a connection diagram. On the Instructable is the information where the data pin of each sensor connects to the arduino. All the others are ground and vcc.

Hello. It was from reprap page. https://reprap.org/wiki/Prusa_i3_HephestosHere's the direct link: https://reprap.org/mediawiki/images/3/38/Frame%26base_Hephestos.dxf.zip

Hello. You can see a bigger diagram on my page at: https://space.groundzero.com.pt/sensor-de-temperatura-com-lcd/

Hello Soryy i forgot to upload it. They are in: https://www.thingiverse.com/thing:2523319

Hi. The home is on the bottom of the vat. First time you need to adjust the endstop to stop the plate when it touches the silicone.

Hi. I have the library on my GitHub Account (step 5). You can download from there.

Hi. I've try with two trains and one led and works well. One starts, then stops and starts the second. I use this code:#include <legopowerfunctions.h>int fwdSpeed[] = {PWM_FLT, PWM_FWD1, PWM_FWD2, PWM_FWD3, PWM_FWD4, PWM_FWD5, PWM_FWD6, PWM_FWD7};int revSpeed[] = {PWM_FLT, PWM_REV1, PWM_REV2, PWM_REV3, PWM_REV4, PWM_REV5, PWM_REV6, PWM_REV7};LEGOPowerFunctions lego(13);void setup() {}void loop() { lego.SingleOutput( PWM, PWM_FWD2, RED, CH1); delay(1000); lego.SingleOutput( PWM, PWM_FLT, RED, CH1); delay(1000); lego.SingleOutput( PWM, PWM_FWD2, BLUE, CH1); delay(1000);lego.SingleOutput( PWM, PWM_FLT, BLUE, CH1); delay(1000);}

Hi. I can only try on the weekend i can try with my trains to see a solution. I'll see if there is another solution.

Hi I still didn't test with two trains but one led should be enough. Try changing the channel of one train. It can be a problem with RED and BLUE parameters.

Hello. The other trains work in multiple ways. The Lego trains have a standart. The other don't. You need to choose one model/brand and see how it works. I can't help because i only work with Lego trains.

Yes. Instead of using the Lego PowerFunctions Remote, you need an Arduino and a IR led. The ir led send the right commands to the Power Functions Receiver.

Hi. You need an arduino, an ir led and the LegoPowerFunctions library (see step 7). The command to control the Lego Train is: "lego.SingleOutput( PWM, PWM_FWD5, RED, CH1);" Before that you need to inicialize the library:LEGOPowerFunctions lego(13);
