Auto Bed Leveling troubles

[dollarz81]

So Ive followed zennmasterm's youtube video, then fixed the Z_PROBE_SLED bug https://github.com/Maxigraf/Marlin/c...ee7c45f2ffb2a6

loaded the firmware and now im getting this error:

[ERROR] Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)


Any help please!!!

It has to be something in the Marlin code. Reloaded the RAMPS firmware and everything is ok.

Fixed it!!!! wrong motherboard setting!!!


Thanks anyways!!!

Fix one problem...another arises. Step motors moving super slow. UGh

[dollarz81]

When I upload Marlin, I get the following
+Z axis moves extremely slow
-Z axis...no movement; says endstop hit
Same for x and y

Im at a lost here. Any help would be appreciated.

What values do you have for these settings?

//// 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, 150, 0} // set the homing speeds (mm/min)
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,854.91} // default steps perunit for ultimaker {78.7402,78.7402,200*8/3,760*1.1}920
#define DEFAULT_MAX_FEEDRATE {250, 250, 2, 22} // (mm/sec)

#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the homing speeds (mm/min)

// default settings

#define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,200.0*8/3,760*1.1} // default steps per unit for Ultimaker

I changed the values to match yours.

When I attempts to move through the different axis, this is what happens.

+Z: endstop hit....no movement
-Z: step motors move a bit slower than normal
+X: endstop hit....no movement
-X: Slow movement
+Y: endstop hit...no movement
-Y: slow movement.


Would it be possible to just post your configuration.h file so I can go through line by line to see where mine has errors?

See this thread: http://3dprintboard.com/showthread.p...correct-offset

The fact it won't move at all on the X & Y is probably because you have these set TRUE

#define min_software_endstops false // If true, axis won't move to coordinates less than HOME_POS.
#define max_software_endstops false // If true, axis won't move to coordinates greater than the defined lengths below.

My Configuration.h is attached.

Also, it is possible some of the confusion is coming from this if you have the HOME_DIR set to +1.

// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1
