Dear all, I need to know to what extend Linux CNC could be used to manage an infrared SMT reflow oven. Any ideas are welcome.
I just purchased an old professional oven, a small one, around 2.5 meters long (some ovens can be 5 meters long or more). It has 7 heating zone up and 7 heating zones down. Each heating zone has a temperature sensor. Also a motor to manage a small train inside the oven with 3 different speeds. In the end, there is also a need to cool down with a ventilator at different speeds. This oven is 20 years old and managed using an Amiga computer running on floppy. The Amiga displays 14 zones, red when too hot and green when in line. Sometimes the Amiga does not boot or does not work very well. There is a need to modernize the oven quickly. The overall quality of the oven is excellent and it should be preserved. My idea was to connect LinuxCNC with: * One X axis * One or more ventilators * 14 temperature sensors * I don't know if power is being switched off/on or if it is leveled. * Alarm censor triggering emergency shutdown. For example, in LinuxCNC, can we use temperature as an end-stop, that would trigger on/off in temperature, just like we stop a motor or start it? I already know the perfect temperature for each zone. There are MANY very good old ovens around, available for nearly nothing. Do you think it would be valuable to use LinuxCNC to control reflow ovens? Also, it would make building custom ovens easier, that would compete with professional ones. Also, I would love to be able to build a custom interface showing the oven state (14 zones) and a temperature curve. Do you think using LinuxCNC would be a good idea? Kind regards, Jean-Michel
