Monoprice Ultimate 2 Comments and Bed Leveling

[SamiHeikkinen]

@SamiHeikkinen

Hi Ender5r, many thanks for the comment/suggestion. Is there a way to adjust this without having the nozzle movement physically throughout calibration process as I cannot set it more than -0,3mm as the bed comes in a way. 1 cm mentioned earlier is actually -5.8mm now that I had a change to measure it more precisely. On the DrVax instructions I selected V1 and then adjusted the bed based on this. I don’t know if I actually should go for V2 but I do afraid that I’m going to get hit on the bed during process. And why would it not work with V1 as again, everything is seems to be level and calibrated but it just starts now 5.8mm above the plate…

Okay seems that it was from CURA, located some new start code from reddit;

With that so far so good. What I did overall that adjusted bed with V1 and used code above in CURA 4.8.0. At least its printing now on bed level.

good news. It’s nice when it’s working.

In cura 4.8 printer settings, which initial settings works, I was using Wanhao Duplicator 6, is that the one to use? or should try Monoprice Ultimate 2?

Did not get answer to previous Post. does anybody know which

I tried new start code from reddit per Sami Heikkinen, It works but it skips bed leveling. and rapid move to start position. What is the G code for auto bed leveling?
At this point i will probably continue using cura 4.3 that came with machine.
I would like to be able to use some of the features in 4.8.

I’m not quite sure what you’re trying to do, but I feel it’s always best to use the profile built specifically for your printer model.

G29 is the Marlin code for ABL. You can add it to the Start Code in Cura.

I’m a bit confused as well as to what you are asking. If you mean the Start G-code (“initial settings”), you can always make your own. One of DRVAX’s videos has generic g-code you could start with (I would think that one of his MP Ultimaker 2 videos has one as well.) If you have a good Start G-code in 4.3, just copy it over to 4.8. Did you try to import your U2 profile in 4.3 to 4.8? (I can’t remember which version changed profile variables, but Cura’s profiles are zip files and the text files within can easily be edited to make them compatible.)

If I change a nozzle or the hotend or the print bed, I’ll level the bed using manual to get close and then use auto leveling. I’m not sure why a printer would be so unstable as to require auto leveling before every print.

Hope this helps.

Cheers

When I got my MU2 I did not understand How auto bed leveling worked. I previously had an Ender 2pro with manual bed leveling. I did not know you first had to level bed manually to start. I thought the auto leveling happened in the software. After watching Dr Vax video I realized and leveled bed. I do not level bed before every print. Bed leveling works fine.
I am going to copy start code from Cura 4.3 to 4.8.
Thanks

hello @Irv_Shapiro , i haven’t been here in a while. i had a question about bed leveling. what does it mean when the sensor moves to a spot and turns red? i have seen go to some spots but does not turn red.
