Bought one of these PID controllers for a plastic-injection molding machine (desktop), but now it's going into a kiln (controlling electric heating element with a solid-state relay). They look like versatile devices! (Am having to upgrade the thermocouple for the higher temp range.) What would be even more useful would be some kind of interface so the temperature could be set by a PC (USB, for example). As it is, it would have to be set manually. There's also no output for the actual temperature to be read. So depending on the need to change and/or monitor the temperature, this controller might not work as well as the microcontroller-based solution for the particular application. Off topic, that looked like an M-head Bridgeport in the video. I'm in the process of moving to an R8 spindle machine (a Pearson, an Italian-made machine from the 50's, in good shape), having tired of not having access to the cool R8 tooling options. --Dale ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
