LinuxCNC is overkill for an oven controller. I used an 8-pin AVR uP for the same thing. The entire computer, memory and all is In tere at a cost of $1.79. They are easy to program. All you need is a PID control loop.
If you want overall look at the Raspberry Pi. It has 40 io pins and runs Linux cost is $35. > On Aug 2, 2016, at 11:56 AM, Curtis Dutton <curtd...@gmail.com> wrote: > > Hi everyone, > > > I'm in the middle of designing a paint curing oven for my shop.
