Hi everyone, I’m working on a home automation prototype using Arduino Mega + RFLink to handle 433 MHz devices. The plan is to move from a breadboard setup to a custom PCB. I’m stuck on a couple of design aspects: PCB layout for RF modules – best practices for antenna routing, grounding, and...

PLCs adjust feeds, speeds, and tool paths dynamically. Material properties directly impact these PLC decisions. This guide explains CNC material selection clearly. https://www.justway.com/blog/CNC_Machining/How_to_Choose_the_Perfect_Material_for_CNC_Machining_A_Comprehensive_Guide_fb9e953e.html...

I'm currently working on a project to integrate an ESP32 with a PLC system for controlling multiple inputs and outputs, including 8 digital inputs, 4 analog inputs, and 10 relay outputs. I came across this project...

Hi all, I was reading this article on PLC troubleshooting and online debugging: PLC Troubleshooting and Online Debugging It covers general techniques, but I’m specifically interested in how others approach online debugging with Siemens PLCs (S7-1200/1500 series) in the field. What’s your...

I am studying this PLC project that uses an ESP32 with DC/DC converters, 8 digital inputs, 4 analog inputs, and 10 relay outputs: https://www.pcbway.com/project/shareproject/PLC_ESP32_DC_DC_RLY_8_DIGITAL_INPUT_4_ANALOG_INPUT_10_RELAY_OUTPUT_80244464.html I’m planning to build this project myself...
