Bilinear bed leveling w/BLTouch not working #5868

Closed Psyc0Flyer closed 6 years ago

Psyc0Flyer commented 7 years ago

I recently configured RCBugFix and uploaded to my Azteeg X3 Pro board and I can not get the autolvl to work! My probe works fine and probes the defined points correctly but when it prints, the nozzle still digs in a little on one side. What do I have to do to get this working properly?? I have tried M420 S1 to enable auto leveling, M500 after probing and everything. I get the readout after probe but nothing is compensated for the bed irregularities.. PLEASE help!

Here is what I get when finished probing READ: Bilinear Leveling Grid: READ: 0 1 2 3 READ: 0 +0.28 +0.24 +0.36 +0.21 READ: 1 +0.25 +0.20 +0.16 +0.07 READ: 2 +0.10 +0.07 +0.08 +0.05 READ: 3 +0.23 +0.20 +0.18 +0.14

This is my starting script in S3D G21 ;metric values M107 ;start with the fan off G28 M420 S1 M420 Z0.7 G29 ;AUTO PROBE M500 ; SAVE AUTO PROBE RESULTS G1 X2 Y2 Z0 M109 S245 ;set extruder temp and wait M116 ;wait for temps to stabilize G92 E0 ;zero the extruded length G1 F200 E20 ;extrude 10mm of feed stock G92 E0 ;zero the extruded length again

M420 is for Mesh leveling(manual), which is totally different than bilinear leveling(auto). You should only need a G28 followed by a G29. I would remove the M420/M500 commands and see if that helps. Make sure you have your Z probe offset set correctly.

M851 Zxxx followed by an M500 is used to set the offset in EEPROM. You only need to do this once when you have the correct height figured out(ie you don't need it in your start script).

As a rule of thumb I never put M500 in my automatic scripts. This seems like a good way to accidentally destroy your EEPROM settings.

Psyc0Flyer commented 7 years ago

I used that script on the last try to see if it helped. It has already been deleted. I have done the M851 z-2.8/M500 but what I am saying is that after everything is done, it does not apply the compensations for the bed so it still acts as if it never probed in the first place. If I were to print without probing, I would get the exact same issue so therefore the probe calibration is not being applied.

From what I can tell your firmware config looks correct. I just uploaded the RCbugFix today and configured my Delta(Ramps 1.4) to use a BLTouch.

I verified that the compensation is working by triggering the probe, in several spots, several mm above the print bed; then i printed a part. It is actively compensating. Maybe you could try this?

It would rule out a hardware or offset issue.

The other option is to disable EEPROM settings and plug your probe offset and any other EEPROM settings directly into the config file. That is how I just setup mine. Maybe the EEPROM offsets are not being read correctly for some reason.

cozierad commented 7 years ago

The only other thing I can think of is that bilinear leveling used to only work with an odd number of points.

ie

define ABL_GRID_MAX_POINTS_X 5

instead of

define ABL_GRID_MAX_POINTS_X 4

This one is a bit of a shot in the dark...

How would I do this?

Also what about this section?

Bob-the-Kuhn commented 7 years ago

Actually, M420 is for all the bed leveling systems in RCBugFix. Sections are added/deleted based on if mesh leveling is enabled or if one of the Auto Bed Leveling schemes is selected.

I wouldn't recommend using M500 unless something has changed. The EEPROM literally wears out a little every time it's written.

Definitely disable the EEPROM until you have things working as desired. The settings in EEPROM override a lot of the settings in your configuration files. You can find examples in this forum of people pulling out their hair because they'd make a change in their config file but the EEPROM would keep on overriding it with the old value.

To disable the EEPROM just comment out EEPROM_SETTINGS in configuration.h.

Sanity check - go to each of your G29 probe points and use the M48 command to measure the repeatability of your BLTouch. Your compensated Z height is at best as accurate as the readings you get from M48.

FYI - don't do a G28 after you've done a G29. G28 turns off bilinear bed leveling.

Increasing the number probe points definitely improves the results of G29. You're running 3x4 now. Try 5x5.

Any idea how far off the compensation is after doing the G29 command?

Psyc0Flyer commented 7 years ago

Looking at the printer, let's say the left 1/2 prints good and the right is into plate. I am using buildtak so you can imagine my frustration having gouge marks in my build material..

I have 1st layer settings at 100% and my probe offset is -2.75.

I am not a very comfortable coder so is there any way you can kindly walk me through what I need to do? I can handle commenting out the line in code but that is about as far as it goes.. Lol.

I M48 1 single spot and this is what I got: Mean: 2.906875 Min: 2.840 Max: 2.927 Range: 0.088 Standard Deviation: 0.023407

I just looked up buildtak. Nice but not cheap.

You're not actually changing code when you set/enable/disable items in Configuration.h and Configuration_adv.h. You're just setting parameters and enabling/disabling flags used by the code and the compiler. You're expected to modify these files and pins_AZTEEG_X3_PRO.h to match your machine.

To disable the EEPROM open the file configuration.h, do a search for EEPROM_SETTINGS and then add // at the beginning of the line.

Have you tried changing your probe offset? Any error in it directly affects what the system thinks Z0 is after G29.

Try using the "paper between nozzle and build surface" method to look for high/low spots with leveling enabled and then disabled. There should be an obvious improvement.

Psyc0Flyer commented 7 years ago

I have already done all of that (enable/disable/set) specific lines in code since your post. I have had my printer working for quite some time now (Printing, not probing) and I am an original backer for the BLTouch but it never seemed as though it was working properly since I was using Repetier. I just recently switched to Marlin because I was told that it supports the probe and Rep does not.

When I first load the code, I always do the paper/nozzle calibration so I know what the offset would be (M851 Zxxx) but I only have done it in 1 spot (Middle). Is there something that I should do differently? I do not understand how I would do the paper test in multiple spots and only enter 1 # for the offset..

Bob-the-Kuhn commented 7 years ago

I hope you're using an RCBugFix that's less than a week old. Older ones had a minimum speed limit where if you probed too slow the BLTouch signal could be missed which results in the head being pushed into the build plate until you hit your kill switch.

So you're the one to blame for that 5mS pulse from the BLTouch! Not the best decision they made.

The Z offset moves everything up/down at once. Based on your printing experience I suggest modifying it by 0.05 or 0.1 and see what happens. Sorry, too late at night and I don't remember if going from -2.75 to -2.65 raises or lowers it.

I'm a little surprised at the M48 results. They imply that each step pulse (when micro stepping is set to 1) results in about 0.025mm movement. I'm not used to seeing dedicated 3D printers with that course of a minimum physical movement.

The more I think about it the more I'm convinced your path to better prints is to go to a 5x5 grid and to adjust your Z offset. Don't forget to put your final offset back into your config file.

Psyc0Flyer commented 7 years ago

I am using the latest RCBugFix. The -2.65 would raise the nozzle away from the bed. The higher the - #, the more "into" the bed it goes. I do not think I have micro stepping activated unless it is on by default. You say not to forget to put it back into the config file. What exactly are you speaking of and where?

Bob-the-Kuhn commented 7 years ago

Z_PROBE_OFFSET_FROM_EXTRUDER in Configuration.h is the variable/setting you need to update. Once you've set this then you no longer need to manually set it with M851.

At power up or after a reset the offset is loaded from EEPROM if that is enabled. If the EEPROM is not enabled then it uses the offset from the Configuration.h file. M851 changes the currently used offset. A M851 specified value is lost after a reset/powerup unless saved to the EEPROM via the M500 command or manually copied into the config file.

I have the same problem (briefly mentioned in issue #5817 ) but the fact that I didn't own a legit BLTouch lead me to rethink if it was a sensor problem or not. You seems to have a legit one and the same problem as me. Maybe I screwed up Marlin and it's not the sensor's fault!

The G29would effectively compensate for the bed leveling but not enough in one side of the printer. I do know it do his job (stepper whining) and with a heavily tilted bed (-10mm in one side), you can see it working. But still like 0.2mm error in one side (X max in my case).

I tryed with linear, bilinear. 2, 3 or 4 points. With and without EEPROM. With the lastest RCBugFix. No luck.
Z offset is supposed to be good (All the left part + center of the printer is fine), only the very end of X is wrong.

Here is the picture of mine, I wonder where your error occur (which axis):

Bob-the-Kuhn commented 7 years ago

@m600x

I'm guessing here ... but is the 0.2mm error section outside the probe area? Can you modify the xxx_PROBE_BED_POSITION settings to include more of the error section? With a BLTouch type of probe there'll always be a strip along two edges that the probe can't get to.

You could try a 5x5 bilinear grid. That was the magic bullet on a couple of issues but those were for errors within the probed area.

Really long shot - try enabling ABL_BILINEAR_SUBDIVISION in configuration.h.

By chance is the bed tilt primarily in the X direction and are you running Z_DUAL_STEPPER_DRIVERS? If yes to both then you could consider using Z_DUAL_ENDSTOPS. This allows you to tilt the X carriage. Both of these are in configuration_adv.h.

I'm curious about your BLTouch type probe.

If it's a Geeetech 3D Touch then you have no worries. They did a good job of emulating the BLTouch.

If it's not a Geeetech then I have a utility that I'd like you to run. I've proposed a Z servo probe utility that will tell you if the probe is BLTouch compatible.

m600x commented 7 years ago

The probing points are within the printing zone. I modified the max X and Y of the printer to compensate the offset of the probe (X -16 Y -78) so the probe will still reach the whole printable bed.

I'm currently set as:

#define AUTO_BED_LEVELING_BILINEAR

#if ENABLED(AUTO_BED_LEVELING_LINEAR) || ENABLED(AUTO_BED_LEVELING_BILINEAR)
  #define ABL_GRID_MAX_POINTS_X 4
  #define ABL_GRID_MAX_POINTS_Y 4
  #define LEFT_PROBE_BED_POSITION 0
  #define RIGHT_PROBE_BED_POSITION 180
  #define FRONT_PROBE_BED_POSITION 10
  #define BACK_PROBE_BED_POSITION 150
  #define MIN_PROBE_EDGE 10
  #if ENABLED(AUTO_BED_LEVELING_BILINEAR)
    #define ENABLE_LEVELING_FADE_HEIGHT
    #define ABL_BILINEAR_SUBDIVISION
    #if ENABLED(ABL_BILINEAR_SUBDIVISION)
      #define BILINEAR_SUBDIVISIONS 3
    #endif
#endif

So yes, the subdivision is already activated. I'll try increasing the grid to 5x5 and update the result. And no, there's no dual stepper set in the firmware.

The printer is a Leapfrog Creatr where all the electronics have been replaced to RAMPS. I just updated to the lastest RCBugFix (22feb #f9e4717, was on 11feb #0369f97). And see if it change something.

Forked at (if you want to see the full files): https://github.com/m600x/Leapfrog-Creatr-on-RAMPS-with-Marlin/tree/RCBugFix/Marlin

As for the probe type, mine seems to behavior like a retarded clone: deployed pin is always triggered, there's no pulse involving. And sure, I can run your utility!

m600x commented 7 years ago

TL;DR: 5x5 doesn't solve the problem.

I did what you suggest me to do: increasing the grid point from 4 to 5 in bilinear leveling with subdivision activate.
Here are the result:

4X4
Measured (in mm):
0,23 0,24 0,30
0,23 0,21 0,26
0,22 0,22 0,22

5x5
Measured (in mm):
0,22 0,20 0,33
0,23 0,25 0,30
0,23 0,23 0,22

So it is roughly the same result. Increasing did not solve the problem unfortunately.

The following code is used to produce the result below:

Do M48 at a few of the "good" spots and a few of the "bad" spots. The spread should be no more than the movement 2 steps of the motor would produce.

In my case I have 200 step motors. 1 step results in 0.027mm movement. I normally see my spread between 0 & 0.054mm.

At best your grid will only be as accurate as the spread you see with M48.

Bob-the-Kuhn commented 7 years ago

I've got to learn to put my machine back to normal after troubleshooting a problem. Nothing like a few moved pins and an open connection to drive you crazy.

I've finally been able to test my utility with your branch. Attached is the modified file.

To run the test issue a M43 S1 command. You'll need to enable PINS_DEBUGGING near the end of Configuration_adv.h.

Your utility seems to work (can't confirm, ain't got a real one):

Send: M43 S1

As pointed out by playlet, his workaround seems to be disabling ENABLE_LEVELING_FADE_HEIGHTwhich I just did to see if it does improve things.

Will keep updated.

Thanks

cozierad commented 7 years ago

@m600x did disabling the fade height make any difference for you?

I just realized my leveling was not working in a small increments as well.

It does not appear that disabling the fade height made a difference for me.
