[quote=“jan1959”]Will do, will be Monday now got a busy weekend.
Simply put (I Hope) its a 12v DC relay, the coil connected to the +ve and -ve wires that used run to the hotbed heating element ( Desolder at the control board end)
The 24v power supply +ve output is connected to the common contact on the relay
And a protection diode is fitted across the 12v DC =ve and -ve terminals on the relay that were fitted to the hot bed, watch its orientation (Stops any voltage spikes returning to the control board)
One of the wires that used to run to the hotbed heating element is connected to the Normally Open contact of the relay
Then the -ve wire from the 24V powersupply connects to one wire thet runs to the hotbed, does not matter which one
The relay is then activated by the control board as it thinks its the hotbed, the contacts close connecting the 24V to the hotbed heating element
and there you go heats up to 100Degrees and gets to 50 degrees very fast[/quote]
yep, that’s an option too.
By the Way, here are the settings in the cofiguration_h file you asked for :
//// MOVEMENT SETTINGS
#define NUM_AXIS 4 // The axis order in all axis related arrays is X, Y, Z, E
#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the homing speeds (mm/min)
// default settings
#define DEFAULT_AXIS_STEPS_PER_UNIT {64.25,64.25,2560,600} // default steps per unit for ultimaker //<<< setings for the steppers in order X,X,Z,E
#define DEFAULT_MAX_FEEDRATE {500, 500, 50, 500} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
#define DEFAULT_ACCELERATION 1000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 1000 // X, Y, Z and E max acceleration in mm/s^2 for r retracts
//
#define DEFAULT_XYJERK 20.0 // (mm/sec)
#define DEFAULT_ZJERK 0.4 // (mm/sec)
#define DEFAULT_EJERK 5.0 // (mm/sec)

// EEPROM
// the microcontroller can store settings in the EEPROM, e.g. max velocity...
// M500 - stores paramters in EEPROM
// M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
// M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.
//define this to enable eeprom support
#define EEPROM_SETTINGS //<<< uncomment this line!
