Using RC8 with AUTO_BED_LEVELING_BILINEAR enabled. Documentation says that you can override number of points to probe with G29 X Y, or G29 P. Neither command works for me. It still always probes the default number of points hardcoded in the software (in my case, 3x3). Any clues? Also, in this version, is there a way to change an individual probed point's correction? Is there a way to outputby Scott1326 - Firmware - Marlin
This is with RC8. I will try sometime with UBL.by Scott1326 - Firmware - Marlin
mjoyce, I would like to see your config.h if you don't mind. Do you immediately perform an EEPROM save after the auto-level routine (M500)? How can one tell if auto-leveling is enabled, M503? Thanks in advance- Scottby Scott1326 - Firmware - Marlin
Hello Morten, I am also using RC8 and have been trying to get my inductive probe to work with auto bed leveling for some time now, unfortunately without success. I have had better luck with enabling MESH_BED_LEVELING and disabling the AUTO options. MANUAL bed leveling creates other small annoying issues, but nothing that keeps you from printing. However, you have to probe the points manuaby Scott1326 - Firmware - Marlin
Update: Interestingly, when I turned off MESH_BED_LEVELING and enabled AUTO_BED_LEVELING_BILINEAR, I was able to get proper data from the Z probe repeatability test.by Scott1326 - Firmware - Marlin
I'm using RC8 on a cartesian prusa mendel 3. I have mesh leveling enabled. I haven't tried that exact command Obewan, but I have tried probing different points with M48 and V4. Not home right now, but will try that when I am.by Scott1326 - Firmware - Marlin
Yes, it homes correctly. I do have a LCD panel. After I home with a G28 or with the home xyz button on pronterface, it homes and then goes to X100, Y140, Z0. That's what the LCD says, and an M114 says the same thing. A home operation performed with the LCD does and says the same thing. Thanks for any help with this.by Scott1326 - Firmware - Marlin

Roxy, How would you feel about putting up a YouTube video of the UBL mesh setup and use?by Scott1326 - Firmware - Marlin
Hello Roxy, I have tried Marlin UBL, and as a matter of fact, you've replied to some of my questions on github (you may recall that the xy probe positions were off on my setup). I still find it somewhat difficult to use, and occasionally, it has caused some strange behavior on my printer. I'm hoping to return to it when it is a bit more mature and tested.by Scott1326 - Firmware - Marlin
Quotegavatron3000 Hey mate I've had similar issues with this as well, I've found it hard to setup and the gcodes don't seem to respond correctly either, I abandoned the auto bilinear leveling and just stuck with manual mesh leveling and that works perfectly. It stores correctly and you only have to do it once, and use M420 S1 in your starting gcode to activate it each time. Plus it's very easy toby Scott1326 - Firmware - Marlin
Hello Axel, I've found that if you enable EEPROM usage in the configuration file and issue a m500 command after you have your leveling points, that it does indeed save your points. Cheers- Scottby Scott1326 - Firmware - Marlin
I've been trying to get mesh bed leveling to work, because I believe my bed is slightly bowed. Auto bed leveling with a probe never seemed to work. I can do the mesh bed procedure, and all the offsets in my grid are positive. Is this the proper behavior? Printing results in air prints off the bed. I've noticed that if I perform a Z home in pronterface by itself, mesh bed leveling gets turnedby Scott1326 - Firmware - Marlin
I didn't change Z_MIN_POS, but I did change min_software_endstops, and that seems to do the trick. Thanks very much.by Scott1326 - Prusa i3 and variants
Final update: Was able to complete a test print with auto bed leveling, so things appear to be working fine in 1.0.2. Roxy, counter-intuitive to me that disabling max_endstops would cause z homing to fail, but it appears yall are addressing this issue in future releases. I'm supremely confident this will not be the first nor last time I will be burned by over-confidence.by Scott1326 - Firmware - Marlin
Update: I may have found the issue. I had uncommented #define DISABLE_MAX_ENDSTOPS, which for some reason was causing Z homing not to function correctly. I commented this back out again, and now z homing works as before. Auto bed leveling seems to work, but I believe all this testing and crashing has made the x carriage lopsided because on the far right the probe crashes the bed. I will adjuby Scott1326 - Firmware - Marlin
Stephen, many thanks for your help. z_min endstop was not triggering in RC3, so I went back to Marlin 1.0.2 which was working at one time (except for allowing moves below z = 0, which I presumably could have fixed with min_software_endstops). I have the logic correct again in 1.0.2, as z_min triggers when the probe LED lights. However, z homing still does not function. The extruder crashes inby Scott1326 - Firmware - Marlin
Thank you for the quick reply, Stephen. I changed the z max feedrate first, and that did indeed fix the whining problem with the z axis steppers. I tried to do a z home, however, and although the proximity switch triggered (led on), the extruder continued to lower until I had to shut it down before it crashed into the bed (I'm guessing setting the endstops define to false won't effect this).

Was using Marlin 1.0.2 on my Prusa build and decided to install auto bed leveling. For some reason I could not get the printer z axis to move below the z endstop (proximity switch) even with G92 commands and changing Z_PROBE_OFFSET_FROM_EXTRUDER. So I decided to upgrade to 1.1.0 RC3. Now I cannot get the Z axis to home at all, although normal Z axis moves work fine. On a z home command, the mby Scott1326 - Firmware - Marlin
Just upgraded Marlin to new RC (to try to fix auto bed leveling problem). Z steppers work fine during normal movement, but immediately stop and whine continuously during Z home operation. Only other thing I changed was a proximity sensor in place of Z min endstop. Any suggestions greatly appreciated.by Scott1326 - Prusa i3 and variants
Update: After including a G92 Z2.1 command in the Slic3r gcode, I noticed that pronterface gives a 'endstops hit Z:2.14' message after performing the auto-level and before printing. Any remedies for this?by Scott1326 - Prusa i3 and variants
Just added a proximity sensor for auto bed leveling. Auto leveling seems to work fine (grid mode), printer homes all axes and runs leveling routine. Z_PROBE_OFFSET_FROM_EXTRUDER is -2.1mm. I can home z axis then run a M114 command, and printer gives me Z = 2.1, then run a G1 Z0 command to move extruder to actual printing height on bed. So far so good. I queue up a part in Slic3r, include theby Scott1326 - Prusa i3 and variants
Trying my first somewhat large print, the extruder bounces over the previous layer. As can be seen in the video, this leads to wavy layers and eventually layer drift. The video shows just the first layer printed, and already the extruder starts bouncing. What is causing this? I think my bed leveling is ok, as smaller prints seem to come out fine.

Hi Roger, Possibly not clear in my original post, but I have had a 3mm extruder working, though not well, with the 1.75mm filament I am using. The current V6 extruder that I am using and trying to get working is indeed a 1.75mm extruder. Scottby Scott1326 - Prusa i3 and variants
Just bought an all-metal V6 hotend (pictured), but cannot get it to print before it jams. Printing 1.75mm PLA into a 0.4mm extruder. I have the fan turned on constantly (Indeed, it would not extrude at all without the fan on. My guess is that the cooling fins got too hot and heated the PLA which made it soft and impossible to feed the filament). I was able to have some small success after tuby Scott1326 - Prusa i3 and variants
enif, thanks for the quick reply. I managed to figure out this one on my own. Apparently, I was using an older version of Marlin that did not have a #define for a REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER. This youtube video was very helpful: . Cheers.by Scott1326 - RAMPS Electronics
Just finished assembling Prusa i3. LCD discount smart controller powers up (and beeps when button pressed) but shows nothing else whether on usb power or not. Believe I have installed software correctly and have tried different contrast on lcd screen. Also have switched cables on lcd board, but to no effect. Any ideas?by Scott1326 - RAMPS Electronics
Aha, got it. Thanksby Scott1326 - RAMPS Electronics
Just finishing my Prusa i3 build, and realized that my Ramps board w/lcd control panel doesn't have usb adapter. Turns out I do want to be able to connect to my pc via usb. Ok to solder an adapter in now, and how exactly do I go about it?by Scott1326 - RAMPS Electronics
