host software temp problem
June 19, 2009 12:45PM
My reprap is almost done, but the temp in the host software is still wrong. The thermistor works because it gives the right temp in the firmware test (where you watch the temp in the serial window). The host software does one of three things, in linux it says, 3,4,5 but in seemingly random order and frequency. In windows it will either say 255 or 0. I know my pin is right, but it just seems like the host software is making up the value. Thoughts?

And I'm using a sanguino, gen 2 electronics

I'm running the debug right now and it is trying to get a temp from the board.

Now it says debug: queueRespond: attempt to queue: M105; get temperature to a non-running output buffer. [###.###s/####ms]

I have changed the thermistor table and the host software is still giving me the same numbers...

Scratch that, I can get different values but it never update the number even though in command prompt it says it is getting new temp values.

values of random 255 or 0 is normally indicating an unconnected input. Since you can read the temp in some tests OK, check your pin numbers in pins.h in the firmware against the wires.
It sounds like you've done that, though.

Restart the host, watching for connect errors in the terminal window....

Are you using the gcode or SNAP firmware: sometimes the settings are in different places?

gcode. And I know the pin is right, I have checked in pins.h. Is there anything else it could be?

Try running a serial terminal, and send the M105 command to the Sanguino - you should get back a temperature reading. If you do, the problem is on the host side; if you don't the problem is on the Sanguino side. Check that other commands work, like G1X10.

the serial thing works, it will tell me the right temp.

Can I run the host software without the right temp?
