Using A4988 driver for turntable position control. Coding sketches.

Hello, again, railway modellers! I hope you are interested in the topic of using CNC and 3D-printers to accelerate your layouts development and implementation of your ideas. It seems to me that the main obstacle to mass application in machine tool modeling is the complexity of programming parts. This is a really incomprehensible and complex process, and it is further complicated by the software. I do repeat the thesis from the previous video, I am of the opinion that using a CNC should be no more difficult than using your usual hand tools. I think I've found a solution...

This is first video about my CNC 1310. I'm going to use it for railway modelling hobby and show you its capabilities.

The Wireless Railway Unit is compatible with all sketches, algorithms and Protocol of the URB project. The only difference is the use of wireless data transmission instead of wired buses. You can mix WRU with URB units or other microcontrollers (MEGA, ESP and etc.) in any way. Available only for members of URB Club.

The default PWM sampling frequency for ATmega328 and ATmega2560 is from 500 to 1000 Hz, depending on the selected GPIOs and Timers of MCU. These frequencies are in the sound range, and you can hear the unpleasant squeak of the engine of the locomotive, especially at the start moving. Preconceived opinions of some modelers is the need to set the PWM sampling frequency above 16 kHz so that this squeak is not audible. This is the wrong opinion – the higher the PWM frequency, the worse the traction characteristics of the DC motors. My experience gained as a result of my own experiments is confirmed by manufacturers of model locomotives with DCC control – do not increase, but rather lower the frequency. The frequency of the PWM on DCC decoders is about 100 Hz. This video shows the relationship between the frequency change and the movement of the locomotive

The URB system can control any mechanisms on the railway. As an example, I have developed an original design of a turntable. The basis of this turntable is Body Twister Fitness circle. I have been designing and assembling this device for six months and this video shows the final result. If you are interested in watching the process of creating this mechanism, then write and I will publish the rest of the videos of creating the turntable.

On this module I separated the infrared sensor emitter and receiver. These details deployed relative to the rails by 45 degrees and are located at a certain height above the rails. Also on the receiver is a black slit mask that removes stray radiation. The height of the sensor and the IR-LED above the rails for different scales is selected experimentally based on the minimum horizontal continuous line of wagons in your collection. This design allows you to get a guaranteed signal of the presence of a train at the sensor zone. The system works correctly at any speed of the train, any the number of cars or types of cars and any length of the train.
