Decoupling or Something Else

3didd

hey,

I m a bit new to some of this.

the Summary is that I built a Homemade printer using the Repetier 0.92.8 firmware.

originally got the DECOUPLE Errors.

so update the firmware, like I saw in other posts

Original Details :

#define DECOUPLING_TEST_MAX_HOLD_VARIANCE 20
#define DECOUPLING_TEST_MIN_TEMP_RISE 1

#define EXT0_DECOUPLE_TEST_PERIOD 12000

Based of Forum Notes I Changed Details to:

#define DECOUPLING_TEST_MAX_HOLD_VARIANCE 300
#define DECOUPLING_TEST_MIN_TEMP_RISE 1

#define EXT0_DECOUPLE_TEST_PERIOD 1800000

but has noticed that the error has disappears for the decoupling.

but the Extruder still gets to Temp(230 degree C for ABS) and once it has reached the right temp, the machine starts to print.

then the Extruder Temp starts to drop, EVERYTIME, Print never gets past the first layer until to cold.....

Any chance someone can please provide the correct solution.

happy to upload the configuration.H file as needed.

thanks in advance.

With these values you could also just have turned decoupling test off with decoupling time 0.

If you have a lcd go to debug menu when it happens and see if dry run is enabled (which I think is).

At least with latest 0.92.8 you should then have a message in the log why it happened. Earlier version went easily on a wrong measured bed temperature into dry run without message, but that has been fixed in latest version.
