Hello
I have prusa i3v I followed the instructions downloaded firmware from github entered as it said how to change firmware but when i verify it in arduino1.0.5-r5 i get the following errors
SERIAL_PROTOCOLLN(((READ(X_MIN_PIN)^X_ENDSTOPS_INVERTING)?MSG_ENDSTOP_HIT:MSG_ENDSTOP_OPEN));
Marlin_main.cpp: In function 'void process_commands()':
Marlin_main.cpp:1270: error: 'X_ENDSTOPS_INVERTING' was not declared in this scope
Marlin_main.cpp:1274: error: 'X_ENDSTOPS_INVERTING' was not declared in this scope
Marlin_main.cpp:1278: error: 'Y_ENDSTOPS_INVERTING' was not declared in this scope
Marlin_main.cpp:1282: error: 'Y_ENDSTOPS_INVERTING' was not declared in this scope
Marlin_main.cpp:1286: error: 'Z_ENDSTOPS_INVERTING' was not declared in this scope
Marlin_main.cpp:1290: error: 'Z_ENDSTOPS_INVERTING' was not declared in this scope
in the marlin_main.cpp i only changed the configuration.h files as instructed by the guides
Please help been tying t figure this out for 2 weeks
Thank You

For those trying to use a RUMBA board like me.
I've managed to operate a hobby servo connected on ext3. Pins 2 / 4 / 6 has +5v / gnd / pwm2 signals.
I've added on pins.h file the following text in red:
------------------------------------------------------------------------------------------------------------------------------------------
#define LCD_PINS_D6 41
#define LCD_PINS_D7 40
#define BTN_EN1 11
#define BTN_EN2 12
#define BTN_ENC 43
#ifdef NUM_SERVOS
#define SERVO0_PIN 5
#if NUM_SERVOS > 1
#define SERVO1_PIN 4
#endif
#endif
#endif //MOTHERBOARD==80
------------------------------------------------------------------------------------------------------------------------------------------
Be careful about polarity for the servo. Servo's plug normally has +Vcc in the middle, I switched possitive and negative servo wires position and connected as in the attached photo and works ok. Pay lots of attention to polarity of possitive and negative wires or you'll burn the servo and/or damage the board.
The servo I'm using for tests it's a hextronik mg14, no problems, min/max position for me are 0 / 90.

You could try this
// set the rectangle in which to probe
#define LEFT_PROBE_BED_POSITION (X_PROBE_OFFSET_FROM_EXTRUDER+2)
#define RIGHT_PROBE_BED_POSITION X_MAX_POS
#define BACK_PROBE_BED_POSITION Y_MAX_POS
#define FRONT_PROBE_BED_POSITION (Y_PROBE_OFFSET_FROM_EXTRUDER+2)
// set the number of grid points per dimension
// I wouldn't see a reason to go above 3 (=9 probing points on the bed)
#define AUTO_BED_LEVELING_GRID_POINTS 5
//#define ORIGIN_FRONT_LEFT
//#define ORIGIN_BACK_LEFT
//#define ORIGIN_FRONT_RIGHT
//#define ORIGIN_BACK_RIGHT
I should just say I didn't come up with this, I copied it from Roxy's configuration.h.

Just got this ABL setup and running great but the ONLY thing I dont like is how the probe retracts between probing. Is there a setting to keep the servo down while probing and then lift after the last probe?

Also, doesn't it seem like there should be a Z_RAISE_BEFORE_RETRACT setting? We have settings to raise the z-axis before homing and before probing to make sure we have clearance to get the probe down, but when it's done, the probe just retracts where it is. It works ok for my case, but it seems like someone could have a probe setup where the probe might need a little clearance to retract without hitting the bed.

Thanks guys, got it cranking away and working great for the G29 probe.
Is there anyway to have the G28 z home work the same way? or atleast lift 2-3mm before retract?

So - this looks great. I'm dead sick of leveling the bed. Some PLAs its not so critical, but I;ve got this green stuff that that doesn't stick unless the bed temp and Z height from the bed are spot on. As well, the springs and screw adjusters seem to vary a little over very long prints where there has been lots of vibration (high speed hex infill for example).
Anyway, I upgraded the Sanguinololu board to a 1284p processor and now have the memory space for the auto bed level. But I have no servo outputs on the board.
Anyone connected this servo to the Sang. board before ?
Also, limit switches seem to have terrible repeatability. I'm going to use self adhesive copper tape in each corner of the glass, with a small electrical test probe monted on the servo. Should give better than .05mm precision which is what is required for this.
Also - I assume that the Z probe is connected in parallel to the normal Z end stop switch ?

I would like to see an "Probe bed level" menu item in the marlin menu which does G29.
Also with the "clasic" endstop situation I had, choosing "Auto home" homed all my axis and put the nozzle in the home position.
Because I have auto bed leveling now and safe z homing, it stays in the middle of the bed.
I would like it to go to the home position with the auto home command in the menu.

I use Hall effect sensors so I can probe a 5x5 grid using Roxy's lovely code and get 0.0002 repeatability which is way more than needed.
