Re: Solidoodle 3 Mods, and issues.
Read http://wiki.solidoodle.com/update-firmware , but download the firmware from http://www.soliforum.com/topic/4236/bet … ll-boards/ . Its this version of the firmware you want to compile.
Edit Configuration.h and :
Line 201, remove the leading //:
#define PIDTEMPBED
Between lines 211 and 243, there is the following:
#ifdef PIDTEMPBED
//120v 250W silicone heater into 4mm borosilicate (MendelMax 1.5+)
//from FOPDT model - kp=.39 Tp=405 Tdead=66, Tc set to 79.2, aggressive factor of .15 (vs .1, 1, 10)
// #define DEFAULT_bedKp 10.00
// #define DEFAULT_bedKi .023
// #define DEFAULT_bedKd 305.4
//120v 250W silicone heater into 4mm borosilicate (MendelMax 1.5+)
//from pidautotune
// #define DEFAULT_bedKp 97.1
// #define DEFAULT_bedKi 1.41
// #define DEFAULT_bedKd 1675.16
//Solidoodle3 Standard Bed //{SD Patch}
//from pidautotune //{SD Patch}
// #define DEFAULT_bedKp 100.15 //{SD Patch}
// #define DEFAULT_bedKi 7.65 //{SD Patch}
// #define DEFAULT_bedKd 327.90 //{SD Patch}
//Replicator MK2B Heat Bed //{SD Patch}
//from pidautotune //{SD Patch}
// #define DEFAULT_bedKp 367.89 //{SD Patch}
// #define DEFAULT_bedKi 36.68 //{SD Patch}
// #define DEFAULT_bedKd 922.06 //{SD Patch}
//QU-BD Silicone Bed 200x200 Square //{SD Patch}
//from pidautotune //{SD Patch}
#define DEFAULT_bedKp 304.98 //{SD Patch}
#define DEFAULT_bedKi 52.88 //{SD Patch}
#define DEFAULT_bedKd 439.71 //{SD Patch}
// FIND YOUR OWN: "M303 E-1 C8 S90" to run autotune on the bed at 90 degreesC for 8 cycles.
#endif // PIDTEMPBED
Edit the values that are uncommented and replace them with the values from the M303 E-1 S95 C8. In the default firmware its not the QU-BD that is uncommented, but the Solidoodle Bed (I think thats what I set it to...) is what I left uncommented. Replace the numbers on the lines that do not have "//" at the beginning.
If you have never done any of the above - it doesn't matter what you've fiddled with so far, PID isn't even enabled on the bed by default unless you uncommend #define PIDTEMPBED ... hence why I've said numerous times to read wardjr's thread where this is all explained in great detail.
Once you have edited the values, you can upload the firmware following the rest of the steps at http://wiki.solidoodle.com/update-firmware
Everything you need to cover I have restated for you above - But please read the resources that have been supplied.
