CodfishCatfish CNC machines ideally use MOSFET’s to drive stepper motors for smooth movement and operation. You can’t switch relays on and off for this application. Powering, reversing and other switching can be done with these relays but for movement you need stepper drivers.

CodfishCatfish Yes you can in the eWeLink app. Either inching which counts down. Example set plants to water for 30 seconds inching. Or set timers in eWeLink app of you want to set timer for many times. Also the ability to schedule the device to turn on and off once, or certain days of the week.

CodfishCatfish The laser has a built in safety feature that prevents it from being on. You must use the software to make the master turn on to calibrate and focus the laser. Unless your are ready to cut the laser will never be on. Also the laser uses PWM technology so you must make sure the laser is pulsed with the lowest pulse at first while you focus.

CodfishCatfish Do you offer one that will......seems like a perfectly OK question. Why the hostility?

CodfishCatfish It uses a Micro USB connector and is programmed with the Arduino IDE. You may have to search the Boards manager for the correct driver. If just using the ESP8266 part then that will need the correct driver. If using the Mega2560 part then that is already included in the latest Arduino IDE. DIP switches allow you to select which programming area.

CodfishCatfish I have successfully used PLA, ABS and TPU but you will have to adjust your settings for each. Some filaments require different Nozzle and Bed temperatures.

CodfishCatfish No, this is a LNA or low noise amplifier. It can only receive RX and cannot TX.
