Can't figure out BLTouch offset - 6 years ago
I cannot figure out how to get the leveling values produced by the BLTouch to register. I'm using a custom 3D printer and Marlin bugfix 2.0.x. This is what happens: G28 to home printer G29 and the four corners of the bed are measured. echo: M420 S1 Z0.00 echo: G29 W I1 J1 Z2.43446 echo: G29 W I2 J1 Z2.16985 echo: G29 W I1 J2 Z3.25292 echo: G29 W I2 J2 Z1.50892 I start the print and the pby Jeffsg605 - Firmware - Marlin

Thanks for the explanation guys! M420 V1 was what I was looking for as well.by Jeffsg605 - Firmware - Marlin
Re: Bed levleing has no effect - 6 years ago
I can see why programmers use the rubber duck approach to work through problems. I've made more progress replying to my own forum post this morning than I have in the previous week of working through this problem. Apparently G28 (home) turns off bed leveling. Not sure why but I'm sure that people smarter than me have a reason for it. So by putting M420 S1 after the G28 in my GCode, bed leveliby Jeffsg605 - Firmware - Marlin

Alright, something is turning off M420 in between when I send M420 S1 and the print actually starts. After I do my bed leveling and send M420 S1, I send M503 S1 to view settings and get the following: ... echo: M420 S1 Z5.01 echo: G29 S3 X1 Y1 Z5.00000 echo: G29 S3 X2 Y1 Z5.00000 echo: G29 S3 X1 Y2 Z5.00000 echo: G29 S3 X2 Y2 Z5.00000 ... I then start the print which ignores these settingby Jeffsg605 - Firmware - Marlin
Re: Bed levleing has no effect - 6 years ago
Nope, that didn't do it. These were the steps I did. 1. I enabled EEPROM_SETTINGS in the Marlin Firmware and uploaded to board. 2. Ran bed leveling and set the nozzle to maximum vertical clearance for all points just so I would know if it worked. I understand this will not make a good print. 3. Sent M500 to store bed leveling settings 4. Sent M420 S1 to enable bed leveling 5. Started a print bby Jeffsg605 - Firmware - Marlin

No, I will try that, thank you!by Jeffsg605 - Firmware - Marlin
Bed levleing has no effect - 6 years ago
Hello, I made a custom 3D printer and got everything to work except bed leveling. I currently am doing PROBE_MANUALLY with MESH_BED_LEVELING and LCD_BED_LEVELING. I am using a Ramps 1.4 with Marlin and the LCD screen. I can follow the on-screen instructions and the printer moves throughout the bed leveling points. I adjust the Z-axis, use a piece of paper, all of that. After bed leveling, Iby Jeffsg605 - Firmware - Marlin
