I want to use Mach3 because I will be controlling stepper motors and other relays.
I was hoping to create a dedicated Mach screenset for the different functions, and basically want to
have one single software/control system running the whole process.
A G-code program will start/stop and hopefully interact with the sensors to adjust working parameters.
They are selling real neat little USB thermometers which can log the data. if I could somehow use a vb or a brain script
to read and report the contents of the log file
Hi Ray, that sparkfun product looks great and talking about forming Plexiglas, would it be possible to create a 180 degree u bend
using 3 inch clear polycarb tubing ?
@KTM thanks mate I will have a look a modbus cause if I remember right there is a modbus 3rd party add on.
No reason you couldn't do a temp controller as a macropump. It doesn't require high-rate control. If doing a constant temperature, all you need is a single digital input that indicates when you're at, or above, your set temperature.
My Plexiglas forming experience is limited to vacuum forming 1/4" sheet. Never messed with tube, and hope I never have to. It's not easy stuff to work with. I will tell you temperature control is *critical*. There's a very fine line between too cool, which creates stress concentrations, and too hot, which results in lousy surface finish. There is a nice PDF on the Rohm-Haas site with all the gruesome details on how to handle Plexi. But don't expect it to be easy. Doing it well is very difficult.
