Error Auto Bed Level on Marlin 1.1.5 and 1.1.6 in Geeetech Prusa i3 Pro B #7860

Closed Pablo-GNU closed 6 years ago

Pablo-GNU commented 7 years ago

Hello, I'm trying to get work a BLTouch sensor in a Geeetech Prusa I3 Pro B. All the hardware is working and I can get the grid from the sensor with the different values.

Bilinear Leveling Grid: 0 1 2 0 -0.355 -0.130 -0.250 1 -0.165 +0.105 -0.080 2 -0.175 +0.060 +0.162

But when I print this grid is not applied so the leveling is not working. Here is an photograph.

img_20171006_182251

My Cura starting code is this.

M851 Z-0.7 ; G21 ; G90 ; M82 ; M104 S{material_print_temperature} ; M140 S{material_bed_temperature} ; M190 S{material_bed_temperature} ; M109 S{material_print_temperature} ; G28 ; G29 ; M420 S1 ; G1 X0 F12000.0 ; G1 Y0.0 F12000.0 ; G1 Z0.1 F12000.0 ; G92 E0.0 ; G1 X60.0 E9.0 F1000.0 ; G1 X100.0 E21.5 F1000.0 ; G92 E0.0 ;

I try with and without M420 S1 and always the same. The system is configured with the Bilineal method.

Here are the configuration and configuration_adv files.

Configurations.zip

I don't know what more I can try. The Lineal system do exactly the same. RCbugfix doesn't work too.

I anybody can help me.

Thanks for your time and sorry for my English.

guiseco commented 7 years ago

Same problem every where. Bilinear do not work for me. I'm using LINEAR.

Pablo-GNU commented 7 years ago

Thanks for answer. If you have the same printer and your board is gt2560 a+ please can you send me your firmware and conf files. I try linear but it doesnt work.

fiveangle commented 7 years ago

Have you both tried these options ?

//#define PROBING_HEATERS_OFF       // Turn heaters off when probing
//#define PROBING_FANS_OFF          // Turn fans off when probing
//#define DELAY_BEFORE_PROBING 200  // (ms) To prevent vibrations from triggering piezo sensors
luismi7777 commented 7 years ago

Im the same problem have you solved?

Pablo-GNU commented 6 years ago

Hi everybody. Recently I change the firmware from 1.1.5 to 1.1.6 and I make some test from different methods. Lineal and BiLineal. The results are the same.

@fiveangle yes I tried these options.

@guiseco The lineal method doest work for me.

On this video you can see the BiLineal method

and on this video you can see the Lineal method.

I don't know how to fix it.

Pablo-GNU commented 6 years ago

@guiseco @fiveangle @thinkyhead This is my last test.

I just performed a manual calibration for the bed and everything it’s ok. After the calibration then i perform a Z-Probe Repeatability Test and this are the results:

With this results i send a G29 command and there is the results:

SENDING:G29

Bilinear Leveling Grid: 0 1 2 0 +0.211 -0.011 -0.690 1 +0.199 +0.039 -0.606 2 +0.110 -0.053 -0.686 Subdivided with CATMULL ROM Leveling Grid: 0 1 2 3 4 5 6 0 +0.21125 +0.15398 +0.09671 -0.01125 -0.20370 -0.44685 -0.69000 1 +0.20991 +0.16080 +0.11169 +0.01065 -0.17695 -0.41648 -0.65602 2 +0.20856 +0.16762 +0.12667 +0.03255 -0.15020 -0.38612 -0.62204 3 +0.19875 +0.16338 +0.12801 +0.03875 -0.14032 -0.37329 -0.60625 4 +0.17481 +0.14072 +0.10662 +0.01880 -0.15858 -0.38968 -0.62079 5 +0.14241 +0.10700 +0.07160 -0.01685 -0.19371 -0.42361 -0.65352 6 +0.11000 +0.07329 +0.03657 -0.05250 -0.22884 -0.45755 -0.68625

Now, if i send a G1 Z0 on one corner (X186 Y181) the nozzle is touching the bed without level. So i calibrate the bed without doing G28, moving the nozzle with G1. (G1 X0 Y0 G1 X0 Y181, G1 X186 Y181, G1 X186 Y0) After check that everything it’s ok i repeat the G29 command with this results:

Bilinear Leveling Grid: 0 1 2 0 +0.186 -0.341 -1.336 1 +0.177 -0.343 -1.301 2 +0.066 -0.450 -1.405 Subdivided with CATMULL ROM Leveling Grid: 0 1 2 3 4 5 6 0 +0.18625 +0.02773 -0.13079 -0.34125 -0.63829 -0.98727 -1.33625 1 +0.18713 +0.02910 -0.12894 -0.33773 -0.63113 -0.97529 -1.31944 2 +0.18801 +0.03046 -0.12709 -0.33421 -0.62397 -0.96330 -1.30264 3 +0.17750 +0.02042 -0.13667 -0.34250 -0.62958 -0.96542 -1.30125 4 +0.14801 -0.00864 -0.16530 -0.37046 -0.65649 -0.99102 -1.32556 5 +0.10713 -0.04911 -0.20536 -0.41023 -0.69616 -1.03072 -1.36528 6 +0.06625 -0.08958 -0.24542 -0.45000 -0.73583 -1.07042 -1.40500

And now again if i send G1 Z0 on the same corner (X186 Y181) the nozzle hits the bed.

It’s anything bad with the G29 command and the mesh calculation?

Pablo-GNU commented 6 years ago

@thinkyhead hello. Any update on this?

iz3man commented 6 years ago

would be interested to see some update as well. i see that with bilinear abl the z-axis is moving up and down to compensate, but it seems it's undercompensating on one side, and overcompensation on another. no idea what's going wrong here. using marlin 1.1.6 with a DC42 ir sensor.

thinkyhead commented 6 years ago

Please test the current bugfix-1.1.x branch and report back. Issues might be fixed.

Pablo-GNU commented 6 years ago

I will try it now. Later I come back with feedback. Thanks.

Pablo-GNU commented 6 years ago

Hello. @thinkyhead the results are awesome. Now the printer makes the bed level okey. I have to make some changes on the pins configuration for the GT2560 because the pin for the BLTouch is not defined well. And I have to increase the time for the bed heater because the systems halt. But for the rest, I can't be more happiest. I'm using bilinear.

Thanks for the support.
