Communications issue

#3566

Last night I managed to get my reflow oven working, but only a couple times…

There seems to be some kind of communications issue between the OSPID and the Front-end software. At this point when I press connect, it connects and reads the current values of the Set Point, Current temperature, and % control. Then I can do nothing more. I can’t send commands, profiles, or anything. I’ve tried resetting the defaults, etc. For a while last night it seemed to be working well, I went through one whole reflow profile and it displayed temperature on the graph, communication was working properly, etc. I am going to try it on another computer, but it is very strange that the communications would just stop like that, yet work long enough to get the current status.

I am still having the same problem. The only way around this is after you connect the front end software disconnect it then reconnect it. I have to do this every time.

I am having a similar problem.

The frontend will connect, get some data, and then just stop functioning. The chart will plot a flat line as the output.
Disconnecting and reconnecting used to fix this, but now when this happens, I also am getting a constant zero at the input of the thermocouple, not just on the frontend but also on the osPID screen.
I have checked with a Fluke thermometer the thermocouple itself is giving a reading.
Disconnecting and reconnecting cannot bring the thermocouple input back to life, nor could I get it to work by resetting the osPID using the hardware button.

Only when resetting to factory defaults through the frontend does the thermocouple reading eventually come back to life, but I then have to reenter all the PID constants etc. again.

Anyone kow what I could do to fix this?
