@dc42 Thanks. I spent some time searching and found out one with a thermocouple output - https://evosensors.com/products/close-focus-small-spot-size-infrared-temperature-sensor-with-dual-laser?_pos=1&_sid=745f48207&_ss=r. Do you think, using the daughter board on the duet, this could be an easier connect than the one I asked about earlier, as this could be a straightforward connection?

Also, would love your opinion on my question 2 from before, if I configure the sensor using your Voltage or UART suggestion.

Hello,

I have a Duet3 6XD (not configured yet), I plan to connect a Non-contact IR temperature sensor that has 4-20mA analog output (https://www.omega.com/en-us/temperature-measurement/noncontact-temperature-measurement/fixed-infrared-temperature-sensors/oshfv-series/p/OS-HFV50-601-LT). This is for temperature measurement up to 1300 C, welding application.

My question is in two parts (sorry for basic questions: I am new to DUET and controls in general, so any help is appreciated):

1. Can Duet3 6XD accept analog 4-20mA in any of its IO pins? If so, is there a documentation that explains the wiring and programming of it? Can the DWC temperature chart be adjusted to show up to 1500 C? Can the temperature data be logged and extracted somehow?
2. What would be the best GCode syntax, to include between welding steps, so the process waits for the recently welded bead to cool down to a set point (say, 200 C) before welding the next bead? (there is no extruder heat or heater of any sort) - So will it be M109 or M116 (I don't see a syntax to define temperature setpoint using this) or something else?

Thanks very much.

I plan to use 6XD for an automated welding application. Would it be possible to work with DUET3D technical team to customize/setup 6XD for this at a cost? If so, how?
