Cura 14.07: Where is the bed leveling wizard for UM original?

Recommended Posts

Posted · Cura 14.07: Where is the bed leveling wizard for UM original?

Hi,

I wanted to level my bed on my UM original, but when I use the wizard, the print head moves to the center in the back for the second calibration step.

I think this is the required method for the UM2, but on the UM original the fan is blocking one of the adjustment screws.

Do I miss something or is it a bug?

I'm sure someone will correct me if I am wrong, but i always have levelled my bed on my UM Original manually!

I like that the wizard positions the head automatically to each of the corners. So you do not have to move the head manually (my assumption is that the automated way is more precise) and/or do it step by step via the software or controller.

The wizard was one of the elements that made me happy compared to the leveling procedure for my Prusa Mendel.

Is your fan on the left or the right? (It should be on the right. I know this is easy to do wrong. As it's still on the left on my home printer)

Print head

It is on the left as described in the instruction manual. i don't understand why it should be on the right side now? And if so, would that work? Looks like it will block the right adjustment screw then.

Sorry, it should be on the left, and mine is on the right. (was looking at the machine from the wrong direction)

The bed-leveling-wizard in Cura should account for this and put the head a bit out of the way of the screws...

It did before. With the four adjustment screws it should move to each of the four corners.

Even if I could reach the screws, it is probably not working to level the bed properly if you need to do this based on one location in the center of the bed. So it's useless for the standard UM.

Is this way of working now the 'standard' procedure or should it still be working on the regular UM (maybe my system does not recognize the correct printer)?

Wait a sec. Do you have a heated bed? Because if you have a heated-bed selected, it assumes you have a 3 point leveling system instead of the 4 point leveling system.

Yes, it was selected! My printer is busy, so I cannot check if this fixes the issue now but will let you know.

If this is the case, I would suggest not to keep these settings related to each other. Otherwise the people experimenting with DYI heated beds on the UM1 can be disappointed ;-).

Do you have an ulticontroller too?

I would suggest to generate a gcode file with a leveling routeen so you have no need to use the wizzard.

If you´re interested, I can post my gcode-file as soon as I´m back home...

I have the Ulticontroller, so posting the leveling g-code is very much appreciated Drayson! Think others will like it too.

It's a secret plot to sell more heated-bed-upgrade-kits. But don't tell anyone that.

Think this is the number one USP for selling them :mrgreen:

And yes, you were right. When the heated bed setting is disabled, the bed leveling wizard is visiting all 4 corners again. Thanks for the help.

Sorry, was a damn long night yesterday :-)

Just put the code into an empty .txt and rename it to .gcode. It´s for 4 P leveling with an second round as extention to make the leveling super accurate.

Here we go:

G21 ;metric values

G90 ;absolute positioning

M107 ;start with the fan off

M117 Homing X/Y

G28 X0 Y0 ;move X/Y to min endstops

M117 Start Extended Bed Leveling

M0

M117 Front Left

G1 X42 Y15 F9000

G28 Z0 ;move Z to min endstops

M0 ;Pause

M117 Front Right

G1 Z5.0 F180 ;move the platform down

G1 X148 Y15 F9000

G1 Z0.0 F180 ;touch print head to bed

M0 ;Pause

M117 Back Right

G1 Z5.0 F180 ;move the platform down

G1 X148 Y180 F9000

G1 Z0.0 F180 ;touch print head to bed

M0 ;Pause

M117 Back Left

G1 Z5.0 F180 ;move the platform down

G1 X42 Y180 F9000

G1 Z0.0 F180 ;touch print head to bed

G1 Z5.0 F180 ;move the platform down

G1 X15 Y180 F9000

G1 Z0.0 F180 ;touch print head to bed

M117 Extended Middle

G1 Z5.0 F180 ;move the platform down

G1 X95 Y97.5 F9000

G1 Z0.0 F180 ;touch print head to bed

M0 ;Pause

M117 Homing X/Y

G00 Z10.0 F180 ;move the platform down

G28 X0 Y0 F9000

Have fun with it - if sombody has recommendations it please feel free to modify :-)

b.t.w. I don´t use it any more as I modified my bed to 3P leveling - there I have a similar code...

Hi Drayson,

That is a nice gcode hack. can you also publish your 3point levelling? Then I can compare them and modify to my printer. i also have 3point levelling but my likely my locations are the other way around. I have 2 points in the back and 1 on the front... Thanks
