Error Auto Bed Level on Marlin 1.1.5 and 1.1.6 in Geeetech Prusa i3 Pro B #7860
Comments
Same problem every where. Bilinear do not work for me. I'm using LINEAR. |
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. |
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 |
Im the same problem have you solved? |
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 https://www.youtube.com/watch?v=hHqLBEmPVUc and on this video you can see the Lineal method. https://www.youtube.com/watch?v=S5EU1_-PV3I I don't know how to fix it. |
@guiseco @fiveangle @thinkyhead This is my last test. I just performed a manual calibration for the bed and everything it’s ok. SENDING:M48 P20 V4 With this results i send a G29 command and there is the results: SENDING:G29 Bilinear Leveling Grid: Now, if i send a G1 Z0 on one corner (X186 Y181) the nozzle is touching the bed without level. Bilinear Leveling Grid: 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? |
@thinkyhead hello. Any update on this? |
would be interested to see some update as well. |
Please test the current |
I will try it now. Later I come back with feedback. Thanks. |
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. |

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.
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.
