Saving G29 Bed Level Correction Matrix to EEPROM

[Fri]

Thanks Roxy,
This version of marlin was change to try to figure out what it going on.
Usually I have the pullups uncommented.

Without the true for the software endstops i didn't have any luck, didn't move right.

I need the max endstops to be commented, I have a Y max switch.

When running an M119 it shows Xmas triggered.

I will try it again with your suggestions and let you know.

Thanks again

Attaching your code was helpful.... I'm not sure what you are seeing. But I would try a couple of things to debug it. First, I would get it into a state where it isn't moving properly. And then I would give it an M119 command to see what it thinks the state of the end stops is. It may be possible you have bad wiring or switches. If this fails to show anything that might be helpful, I think I would try rebuilding the firmware with a few changes. For starters, I think I would change:

#ifdef ENDSTOPPULLUPS
  //#define ENDSTOPPULLUP_XMAX
  #define ENDSTOPPULLUP_YMAX
  //#define ENDSTOPPULLUP_ZMAX
  #define ENDSTOPPULLUP_XMIN
  //#define ENDSTOPPULLUP_YMIN
  #define ENDSTOPPULLUP_ZMIN
#endif

to:

#ifdef ENDSTOPPULLUPS
  #define ENDSTOPPULLUP_XMAX
  #define ENDSTOPPULLUP_YMAX
  #define ENDSTOPPULLUP_ZMAX
  #define ENDSTOPPULLUP_XMIN
  #define ENDSTOPPULLUP_YMIN
  #define ENDSTOPPULLUP_ZMIN
#endif

Just to make sure everything has pull up voltage to it to eliminate noise. You won't hurt anything by doing this if nothing is connected to those pins. I would then repeat the above stuff to get the printer into a mode where it doesn't move correctly and try to give it another M119 to see what it thinks of the world.

Probably, I would try rebuilding the firmware with these changes to eliminate the suppression of moves when the printer thinks the endstops are being touched. This is kind of brute force, but if these changes make a difference, that will be confirmation we are dealing with an endstop switch stopping the movements:

#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.

#define DISABLE_MAX_ENDSTOPS
#define DISABLE_MIN_ENDSTOPS


//  #define Z_SAFE_HOMING   // This feature is meant to avoid Z homing with probe outside the bed area.

If I disable the max endstops, x works fine, but Y doesn't home. If I disable both the max and the min, it doesn't compile with the G29 and z probe repeatability on.
If I comment both out, and the the pullups as you suggested, x and y home, but don't bounce and M119 returns all triggered but zmin.

I am still not able to solve the issue on one of the machines. It's really weird. After ABL ( I save it to Eeprom) the z probe/stop triggers x&y. I am really not getting it, I have another machine with the exact same firmware that works fine.
Here is again what is happening and it only happens when the ABL is not erased, it doesn't do this after M502.
When I send G28 the machine homes all axises and rests in the front left corner, the z stop is triggered. So if I hit print, my g code sends another G28 and the machine
homes from where it is at. Meaning the machine thinks x & y are triggered when z is triggered, but they are not. M119 shows Zmin triggered, x&y min open.
When now trying to home only x, it moves away from the stop as if it were triggered, but again, it is not.

If a M502 makes things work again... It would almost seem something is getting stored wrong in the EEPROM. A M503 will print the values of the variables (out of the EEPROM) that are being used. Can you do a couple of things? First get the printer working normally and do a M503. Then get it sick and do another M503 and compare the numbers.

Also, it might be interesting to get the printer working correctly, do a M503 and then read values from the EEPROM using a M501 followed by a M503. Does a M501 get the printer to act sick?

[Fri]

It doesn't work with eeprom safe, I cannot get it to print since after a G29, the bed doesn't come up anymore. If I do a M502 it works again, but it also removes the matix data.

Right now with all the pullups, I cannot home all since the Zstop is a sensor and needs safe z homing. But the machine doesn't safe z with all pullups uncommented.


I will change the firmware back until I can do the G29 and send you that M503.

When ever I use the safe to eeprom the machine act erratic. Should have a M503 without ABL soon

Now I can't get it to safe home anymore.......hmm

Here is the M503 from a firmware with out safe G29 to eeprom. It doesn't safe z at the present...not sure why....

Her is one without the G29 to eeprom but uploaded, and did an M119, then M502,M500,M501 and M119 and nothing is triggered without a motion on the machine.

When you connect to the board, does it say "Using EEPROM values!" ? What does it say the Version is and the Stored Version are?

Here is the M503 from a firmware with out safe G29 to eeprom. It doesn't safe z at the present...not sure why....

The main line code from GetHub did not print out the value for the Z-Probe offset. So, this would imply (at least for this print out) that you are building an unmodified Configuration_Store.cpp file. I'm wondering if you are having problems getting Arduino to load and build the correct set of file? I've had problems with that in the past!

I discovered some errors and fix them, now I get a better initial reading, see below. I also noticed that the safe z coordinates were outside the max print size (did some mechanical changes to the x carriage) and therefore it wouldn't
safe z. All said, now it is still spotty about the safe z, if I connect, it doesn't do it, if I home x and y first (both do not bounce the first time) then it most of the time does the safe z. Not always though and sometimes it does it, but
moves to a position short of where it should go.

Roxy, I think my safe home speed is too fast. Where can that speed be changed. The axis homing speed is fine, but when it moves to the bed center (or whatever position to have the sensor on the bed) it moves very fast.

[Roxy]

During safe Z homing, the line

#define XY_TRAVEL_SPEED 8000

is used from Configuration.h If the speed of the motors was too high for them to move where they are being told to go to, it is possible for the firmware to think the extruder is in a different place than it is.
