XY not moving to center of bed when homing Z

[Luchane]

Hey Guys.

Total noob here. I ran Marlin V1 for LCD 2004 on my printer for over a year now.

I added some fans on the aux pins and LED lights to extruder head for those late night prints. Added Auto bed leveling with servo. Worked awesome until one day. I must have messed with something in the code and the Auto bed leveling was off. It doesnt calc the plane properly anymore and prints iregular.

Thought its time for upgrade. Downloaded the new Marlin firmware. First of all. Well done. It is way better layed out and the fetures in it is awesome.

It does not want to work for me tho. If I home the X and Y axis independantly, It shows "0" on my LCD.
When I do a "Auto Home" it homes the X and Y. Does not go to center of the bed to do Z. Just drops the servo in the X and Y home pos. Also the values on LCD is then X 90.0 Y 135.0 and Z 13.0.

I cant see where it gets those values. Also if I send it a G29. It does not move to the grid points. the servo just drops once in the X and Y home positions.

Here is my config.

// Allen Key Probes, Servo Probes, Z-Sled Probes, FIX_MOUNTED_PROBE, etc.
// You must activate one of these to use Auto Bed Leveling below.
//
// Use M851 to set the Z probe vertical offset from the nozzle. Store with M500.
//

// A Fix-Mounted Probe either doesn't deploy or needs manual deployment.
// For example an inductive probe, or a setup that uses the nozzle to probe.
// An inductive probe must be deactivated to go below
// its trigger-point if hardware endstops are active.

// Example: To park the head outside the bed area when homing with G28.
//
// To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN.
//
// For a servo-based Z probe, you must set up servo support below, including
// NUM_SERVOS, Z_ENDSTOP_SERVO_NR and Z_SERVO_ANGLES.
//
// - RAMPS 1.3/1.4 boards may be able to use the 5V, GND, and Aux4->D32 pin.
// - Use 5V for powered (usu. inductive) sensors.
// - Otherwise connect:
//   - normally-closed switches to GND and D32.
//   - normally-open switches to 5V and D32.
//
// Normally-closed switches are advised and are the default.
//

//
// The Z_MIN_PROBE_PIN sets the Arduino pin to use. (See your board's pins file.)
// Since the RAMPS Aux4->D32 pin maps directly to the Arduino D32 pin, D32 is the

values on LCD is then X 90.0 Y 135.0 and Z 13.0.

That's the location the head should be at when it starts & finishes the Z axis homing.

What does M114 report ? It should report the same location as the LCD.

It looks like your config files are set up properly.

• Z_SAFE_HOMING is enabled
• Z homing will be done with the probe at the center of the bed. The strange X & Y values are because it's the head's position that is reported. The probe will be at 100,100 and then you add/subtract the probe offsets of 10 and -35 to determine the head position.

I think you've run into a bug. The "take two aspirin & call me in the morning" response is to request that you download the latest RCBugFix and see if that fixes the problem. RCBugFix is the very latest Marlin. It has a lot of bug fixes in it so it clears up a lot of these problems.

ULTRA_LCD and REPRAP_DISCOUNT_SMART_CONTROLLER are both enabled. Why is that? I haven't gotten into the LCDs so I don't know if that's correct or not.

---

Some minor notes/questions on your config.

#define ENDSTOPPULLUPS should be enabled. This will enable the pullups on all the endstops. Never hurts and is required when using mechanical switches and most hall effect sensors..

#define NUM_SERVOS 3 - just surprised to see it's not 1. Are you running other servo based items besides your Z probe?

//#define Z_HOMING_HEIGHT 4 should be enabled and set to the needs of your printer.

---

FYI - here's the sections from your config file that pertain to Z homing

#define Z_SAFE_HOMING
#if ENABLED(Z_SAFE_HOMING)
#define Z_SAFE_HOMING_X_POINT ((X_MIN_POS + X_MAX_POS) / 2) // X point for Z homing when homing all axis (G28).
#define Z_SAFE_HOMING_Y_POINT ((Y_MIN_POS + Y_MAX_POS) / 2) // Y point for Z homing when homing all axis (G28).
#endif

#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS 200
#define Y_MAX_POS 200
#define Z_MAX_POS 170

#define X_PROBE_OFFSET_FROM_EXTRUDER 10 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER -35 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER -3 // Z offset: -below +above [the nozzle]

#define Z_CLEARANCE_DEPLOY_PROBE   10 // Z Clearance for Deploy/Stow

[Blue-Marlin]

Please make a M119 in mid air. No unused endstop shall appear in the list. No used endstop shall be triggered
Likely your x and y -max.endstop is triggered.
Ehter deactivate them (//#define USE_XMAX_PLUG //#define USE_YMAX_PLUG)
or invert them (#define X_MAX_ENDSTOP_INVERTING false #define Y_MAX_ENDSTOP_INVERTING false).

[Bob-the-Kuhn]

@Blue-Marlin - I hadn't thought of the X_MAX and Y_MAX sensors always being active. That would keep the head at X0, Y0 until endstops are disabled.

If this is the case then enabling endstops (M120) and then issuing G0 X30 and G0 Y30 would result in no head movement and an "endstop hit" message on the screen.

[Luchane]

You guys are THE best.

Commented out the unused endstops. Z homed as it did before.

Other minor issues to sort out still.

Thanks again for awesome response.
