Hi Ron – I plan to do some testing on my espresso machine sometime in the near future. I’m wondering if you can provide details about the thermocouple that you decided to use. Also, how have you decided to secure the thermocouple to the boiler for temperature sensing? Thanks in advance.

Sorry for the delay in responding. I’m using a Mouser part # 518-4325 (Solid State Relay) and a Liquid tight K type, 2 in probe, 1/4″ NPT Thread (TC-K50MMNPT) from Auberins. My espresso machine, an Astra Mega IIC, has an unused (plugged) 1/4″ NPT bung on the top of the boiler so I simply removed the plug and installed the thermocouple.

I posted over in the tuning forum before I saw this thread so I’m reposting here. I am having the same problem. I installed the PID on my espresso machine and when I connect the front end the input reading drops ~5 deg C (with a 123 deg C set point). If I let the PID drive the temp to the set point and then disconnect the front end the input jumps up ~7 deg C (from 123 input with a 123 set point while front end connected to 130 input with a 123 set point as soon as front end is disconnected.)

I’m using a Mouser part # 518-4325 (Solid State Relay) and a Liquid tight K type, 2 in probe, 1/4″ NPT Thread (TC-K50MMNPT) from Auberins.

okay, I tried with a fresh download and still getting the same result. Any other thoughts?

crazy. ok, so you have the right version of the front-end, since it’s asking for that function. the “ReadProfiles” function is in SPProfile.pde (it shows up as a tab in the processing ide). can you confirm that the ReadProfiles function is there on line 37? perhaps the download was corrupted somehow.

Yes:

void ReadProfiles(String directory)

The Processing executable is in my Applications folder (I moved it there from the downloads folder where it was unzipped originally.) I now copied the profiles folder (with the reflow.txt file in it) to the Applications folder and still get the same error and the same line highlighted.

another thing you can try is running the program from code (instructions here) at the very least this will give you a verbose description of whatever error may be occurring, and we can go from there.

Tried that. Here is the error I received “The function ReadProfiles(String) does not exist.” and the line containing this code ReadProfiles(curDir+”\profiles”); was highlighted.

Yes the driver is installed. I was also able to upload the v1.5 firmware with no problem so the port is working correctly but the front end still doesn’t have any menu options (see screen shot)

Can you confirm that the ospid is plugged in to the computer before you start the front-end?

Yes. I also tried rebooting, plugged in and then launched the front-end and got the same result.
