On my BL Touch, it’s the white wire on the right-hand end: [U]https://forum.drvax.com/forum/3d-printing/7193-bltouch-failing-m48-test#post7193[/U]

Hi,
thanks a lot.
But i think we talk about different Sensors.
Our Sensor is LJ12A3-4-Z / BX for detecting metallic Objects in range of 4mm. But the Problem could bei the Sensor…

Yes, it is a different sensor. My thought was that, like with my BL Touch, there might be a connectivity issue.

Ah, so your printer is trying to probe infinity :wink:

I can think of a couple of ideas: [LIST=1]

  • cover the hole with something metallic, even aluminum furnace tape, or;
  • modify Marlin so the ABL probes a different area; e.g. perhaps a slightly smaller area. [/LIST]

    I scrwed out the Sensor a bit. It helped. Can i modified the Marlin Code? Or you mean modifiy with the gcode.

    26

    You can see if your install of Marlin has a menu option that allows you to specify the bed edge offset for probing. If not, it is possible to modify Marlin itself. If you’ve never done any programming it could be a little daunting, but there are videos on YT that can help.

    I have A monoprice Ultimate 2 and have a problem finding parts. Namely Nozzles. And also don’t understand the bed leveling the “user’s Guide” does not even mention how to use. I press button on screen but don’t know what is happening it goes to position and says “moving” but doe not seem to be doing anything. Then I finally push the button again and it goes to a different position. and so on. When it finishes I don’t know if it actually Leveled the bed or not.

    28

    Does the printbed not move up & down during leveling?

    29

    Have look at this video: [U]https://www.youtube.com/watch?v=X0HnOvVU-Mg[/U]

    Try unplugging the sensor and manually leveling the printer (at least until @Irv_Shapiro weights in ?). This printer is basically a re-branded Weedo F150S, if you are looking for parts.

    Cheers

    Two things I have done that seem to work well on my Monoprice Ultimate 2

    1. I did not like to use masking tape on the glass bed, it rips and u have to change it too often and I noticed that when u buy Overture Filament it comes with a piece of Bilteck (don’t know if i spelled it right) that is 200mm x 200mm in every Box. If you cut 50 mm of of one side it fits bed. and it works great. I have been using it for more then a year. and i have 2 extra when that wares out.
    2. I use The same Nozzles as in use on my Ender 3. The hex is a different size

    Read Dr Vax’s article on how to use the bed auto leveling on Monoprice Ultimate 2. that was great. It cleared up all my questions on that subject. Thanks Dr Vax. Why could not Monoprice explain this in there “user’s Guide”

    33

    I have 2 printers The Monoprice Ultimate 2 and A Ender 3 pro. Each has good points and bad. I seem to get better surface finishes on my Ender. It may be because i use Cura 4.3 that came with the machine I am not sure about changing to 4.8 that i use with my Ender 3 because i understand u have to make a firmware change for the Ultimate 2 and I’m a little little insecure about making that change.
    I like to use the Ultimate 2 when I make filament changes like signs etc.
    But in any case I am sure glad I found this Hobby during this time with Coved 19 shutdown.
    Thanks Dr Vax for all your Videos and help.

    Why not do a test print using Cura 4.8 on the Ultimate? Just keep your finger on the power button the whole time it’s printing.

    35

    I tried that but it started printing too far from the print Bed. as u said had to press the on off switch. there is no stop print setting.

    36

    That sounds like it’s a printer profile issue. Time to search the interwebs for how to fine-tune Cura 4.8 profiles.

    When you say “too far” do you mean the hotend is too high above the bed?

    37

    yes. Nozzle was too far from bed. Filament was extruded so high above the bed it would not stick on the bed.

    38

    I used the Wanhao Duplicator Profile because there was not a Monoprice Ultimate 2 profile

    39

    Try changing the Z Offset. Hopefully, you have that option available in the menu system. Start with -0.1. You might want to follow this video [U]Best method for 3D printer bed levelling - YouTube

    I have Cura 4.8 but also i run the new firmware 2.2.8. It runs fine without ans Problem yet. I had Problem with the Sensor and manually screwed in better Position. The only Thing you have to Change is the Settings in cura for your Printer.
