Downgrading Firmware to .91

[Bobbystone]

Hey All,

I've had my printer about 2 weeks. Its a dual extruder. I've been getting the dreaded decoupling heater problems so I thought I would try to downgrade firmware to .91 When trying to compile the firmware I get the following error:

Arduino: 1.6.1 (Mac OS X), Board: "Arduino Mega ADK"

Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.


I have a couple of other questions. What is the Arduino board type I should select?

Thanks!

Check which Arduino version you have, I had to downgrade to 1.5.5 to have it compiled and uploaded successfully.

[Bobbystone]

Thanks, I'll try that. Are there any settings I need to change in the config.h or anything or is it good to go after that?

Downgrading arduino to 1.5.5 worked, thanks! So far no decouples

[frankjoke]

Good to hear! I learned to resist upgrades when new 'features' are introduced which destroy working solutions.

Anyhow, I am using 0.92 now, I only increased the EXTx_DECOUPLE_TEST_PERIOD to 30000!

... and I fastened the Thermristor!

I have issues with 0.92.2 firmware (uploaded using arduino 1.6.0). Printer only does one print run before everything becomes unresponsive - no heaters no motors. Occasionally get the heater decouple issue when heating bed only. Reinstall everything works sometimes, but only for one print.
I have wasted weeks struggling with latest update.
What RepHost version are people using 0.91 firmware with?? Please help!
