Auto_Bed_Leveling: Enhanced G29 command

[AbuMaia]

Yes, it prints correctly. The G29 calculations seem to work, and do not add the extra 4mm that the G28 does. As for pushing a button or sending a G28 command, both. Home All, Home Z, G28, and G28 Z all have the same effect of adding 4mm to Z.

I have:

#define Z_PROBE_OFFSET_FROM_EXTRUDER -3.85
#define Z_RAISE_BEFORE_HOMING 9 // (in mm) Raise Z before homing (G28) for Probe Clearance.
#define Z_RAISE_BEFORE_PROBING 9 //How much the extruder will be raised before traveling to the first probing point.
#define Z_RAISE_BETWEEN_PROBINGS 9 //How much the extruder will be raised when traveling from between next probing points

After resetting my printer and doing a G28 and M114 I get:
>>>g28
SENDING:G28
>>>m114
SENDING:M114
X:76.00 Y:73.00 Z:12.85 E:0.00 Count X: 76.00 Y:73.00 Z:12.85

Which would be 9mm+3.85mm

Then:

Can you post this same information and sequence?

#define Z_PROBE_OFFSET_FROM_EXTRUDER -10.9
#define Z_RAISE_BEFORE_HOMING 13
#define Z_RAISE_BEFORE_PROBING 13
#define Z_RAISE_BETWEEN_PROBINGS 5

>>>G28
SENDING:G28
SENDING:M114
X:40.00 Y:8.00 Z:23.90 E:0.00 Count X: 40.00 Y:8.00 Z:23.90

The numbers here look correct. 23.9 = 10.9+13. However, this is where my problem is. If I do G28 then G1 Z0, the nozzle is 4mm above the bed. If I G1 Z0 after a G29, the nozzle is 0.1mm above the bed, as it should be.

Do you have a good visual diff program? I'm wondering if you should just switch to my code base? What you are seeing doesn't make sense and my firmware doesn't show the problem so it is difficult to help. How about you move your settings to my code base and if the problem is still there, we both will have the same code and it will be easier to figure out the root cause?

If you are willing to do this... Delete the Pins.h file in the archive and replace it with your existing Pins.h Then move your Configuration.h settings to this archive's Configuration.h file. And hopefully you don't have a UniPanel. If you do, we need to delete bool lcd_clicked() & void lcd_pressed() functions in Marlin_main.cpp.

I don't think so. At least, if I do, I do not know it has that functionality.

I do have a RRD SmartController LCD.

Here is a good, basic one... It will help you quickly compare files to cross over changes: http://winmerge.org/downloads/

Thanks, but I can't use that. I run an Ubuntu Linux machine. I'm installing a diff viewer now.

Yikes! There's a lot of stuff in your config.h that I don't have. I don't know what to do with the calibration section, feedrate, acceleration, steps per axis, etc. It's all mixed up and in different locations than in mine, so I don't know what to change and what to leave.

Do I need to delete those two functions in marlin_main if I have a UltiPanel, yet I also run the M600 filament change command?

[AbuMaia]

I got it figured out. I'm ignoring the calibration section, and putting in my numbers for steps and feedrate and such. Just waiting on word about marlin_main before I upload it.

If you have an UltiPanel... Just delete those two functions. Those are needed because I have a switch hard wired to a GPIO pin and something has to tell the M600 firmware that it is OK to proceed. Those functions are already provided in the Ultipanel code.

Yes, ignore the calibration stuff. That stuff is just to make it so I can change any one number and everything gets calculated correctly.

Ok, taking them out. I have a switch plugged into RAMPS being held closed by the filament entering the extruder. Once the filament end releases the switch, it triggers M600. I'm 34% and 7:26 into a print right now, so I'll upload your code with my numbers after it finishes, likely sometime tomorrow.
