defualt heated bed PID settings

I tried doing the PID calibration for my heated bed and replaced the values without at least writing them down. now it can no long reach temps above 90c which is keeping me from printing ABS. Could someone please post the default PID settings so I can get this corrected?
PLEASE AND THANKS.

Those of us who followed the manual got the values from the pid autotune.

Yeah and it didnt work.
The defaults now if you don't mind.

If you want the defaults, clear your eeprom with the arduino script.

what bot said. clear the eeprom, reload your firmware with the latest fork, that will give you your defaults. I do not have defaults only my modded eeprom sorry. search the forum for PID autotune, there are a couple of threads for fine tuning your hotend temps.

There is no bed PID tuning procedure listed in the assembly manual.

hey thanks a lot, Ironcoot.
glad someone on this board is willing to lend a hand.

The reason why the defaults are not mentioned is because they are not even used once.
You also have the defaults in the arduino program that you have on your computer.

I do not understand this statement.
If the instructions from the manual are followed to the letter, the bed-PID values used for printing are the default values from the firmware build.
The manual includes instructions on how to tune the extruder-PID values based on data from the "M303" gcode command -- but there are no instructions to use the "M303 P1" version for the bed.
On a related matter, I have been unable to get "M303 P1" to complete without timing out, so I continue to use the default bed-PID values. (Max V2; 12V Onyx V7)

Hnm. Mine must be an older manual then.
Sorry for that.
