Re: [Emc-users] Curing Oven

With everyone pitching in on what they think is the best controller, I'll put my two cents in... If you are doing this as a learning exercise, or to get better with LinuxCNC, then by all means do it and enjoy. But if you just want a working oven, get a DIN temperature controller and move on

Re: [Emc-users] Curing Oven

Yes I used just a bare AVR chip but the arduino nano is easier to use and I've seen them for $3 with free Shipping. They can hold at least 2000 lines of code and run at 16 MHz. The Mano has more then enough PWM and ADC Pins and can drive an lcd display for status and control. You get quite a

Re: [Emc-users] Curing Oven

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

Re: [Emc-users] brass and warpage during machining.

Heat treating means applying heat to whatever material on earth. Hardening is one aspect of it, annealing another, softening or making malleable yet another. It is not to be expected hat all materials behave the same. Everyone knows that brass and other copper alloys harden by mechanical

Hi everyone, I'm in the middle of designing a paint curing oven for my shop. I am going to control it with linuxcnc. The oven only runs at 120 Degress Farenheight ~ 50 Deg Celsius So far I plan on using LM35's for temperature reading. A 120V 1500W heating element driven with a solid state

Re: [Emc-users] OT: Servo drive tripping out

I am wondering if it just temperature related, I will have to turn the AC unit back on, and put a temp sensor in the cabinet, and see if I can get a common trip temperature maybe. Dropping the cabinet temp 20 degrees has got to make some stuff contract a little bit, maybe enough to make a crappy

Re: [Emc-users] OT: Servo drive tripping out

On the Mazak lathe I often have problems with the drives tripping out when there's high humidity levels (85% and up). In fact, the drive doesn't want to turn on at all, whenever I turn on the machine it's on fault state. Most of the time it happens on one of the drives, but if the humidity is too

Hello Guys, I have a Fanuc triple axis servo drive on one of my machines, and since last Thursday it has been randomly tripping out, and faulting the cnc control. It is from roughly 1995, and has been running just fine up until this point. Even while just sitting powered up, but with no servo
