Calibration problem on Ultimaker original + for the first use

Recommended Posts

Hello everybody,

I finished up my original Ultimaker + printer. I download cura 15.04.6, then I download the firmware, I followed the heated bed calibration instructions. So I begin with Z. limit setting I put the nozzle in the center as requested, I put the heat bed 1 mm nozzle and I set the stop end race Z. No problem. WIN_20160815_13_44_15_Pro.thumb.jpg.7658bea71bf1c4448d58e9dd2d9eb239.jpg

After I do the verification Ultimaker all is ok. I connect to the printer for setting the heat bed.5a3320493a724_2016-08-15(3).thumb.png.f779aa273af1ad80a62d327f44f4de2c.png

To recheck the Z abut the setting wizard.

And there begins the first problems the buttons to move up to 0.2 mm OR 10 mm does not rise but down. In fact, the button for mounting 0.2 mm down from 10 mm, for mounting the 10 mm down to 0.2 mm, one to descend from 0.2 mm down to 20 mm and that descend to 10 mm down to 30 mm.5a332049bfd7c_2016-08-15(5).thumb.png.d6c3b4467f0230745537ad599515f6e1.png

Well I said I manual adjustment I made early enough for the stubborn Z, so I continue.

The heat bed back and muse moves top left, I rule the stage with the adjusting screw and I put a sheet of paper between the nozzle and the board as a consultant. And when the nozzle stuck the paper is ok. WIN_20160815_14_07_24_Pro.thumb.jpg.cc7597fb0d1a6850073be1684772cca7.jpg I move to the next position.

And the drama is there, the nozzle moves to the back center of the heat bed but 15 mm from the tray, it is impossible for me to set the tray with the adjusting screw.

Same for the right front position.WIN_20160815_14_11_48_Pro.thumb.jpg.12e6377c8fef7ac8f23616a5580be57d.jpgWIN_20160815_14_16_38_Pro.thumb.jpg.5427ea01f3b8a0f9382df79e9da9dc1b.jpg

I'm confused here.

Does anybody know this problem Installing the after-heat bed?

Does anybody-have an idea?

I'm very thankful for every help!

Even better. Forget about the calibration thingy.

Do Prepare/auto home

Then move the hotend to the basic 3 corners and make the nozzle 'kiss' the bed slightly.

That will calibrate the hotend to 0. Repeat front corners after adjusting the one on the central back of the bed.

Also you can get a feller gauge and after doing the home, go prepare/move axis/move 0.1mm/move z

To move the bed just 0.1

This way (with a feller gauge you can 'fell' if the gap it's really 0.1 when calibrating the bed screws.

After an autohome x/y can be moved by hand, but Z motor will be blocked (so you can do this operations). To unlock it use Prepare/Disable steppers

Your post is a bit confusing to me so let me explain a few failure modes:

1) Z never ever goes up. Always down.

2) Z goes wrong direction. When you try to home it goes all the way down and makes bad noise.

3) Z moves wrong distance (usually half) so when you home it from the bottom it never reaches the top - if you home near the top it homes properly. When you print things they are half height.

4) Z works fine usually but sometimes bed falls suddenly for no apparent reason (this is normal - steppers turn off after a minute of no use).

5) Z moves one direction but refuses to move the other direction (limit switch problem).

Is your problem one of 1-5 above? If not maybe a video will help as the words you wrote don't make complete sense in English (sorry!).

Yes, sorry but my English is not that good.

So I go back step by step. And with the bed Calibration Wizard, in English, for this to be clearer on the capture screen.

In reality I am facing problem three.

No problem for the communication check up, temperature and end-stops.

5a332054c5119_2016-08-15(3).thumb.png.3bed2f19b063ea36a6a39486d0b132e5.png

The first problem occurs during the phase of levelling bed (this is akin to the problem (a) you mention);

So by clicking the buttons nothing works as it should:

5a33205542edc_Pic2.thumb.png.75d3e794c0d79c61c62d5cfc30e962b4.png5a332055eba6f_Pic3.thumb.png.755ca5fe8acabf02071de1fab5e75d01.png5a3320564ac06_Pic4.thumb.png.e4f32d6189da95880749e674c22e4c82.png5a332056926a0_Pic5.thumb.png.e593c3826d7a70a1f00c6304360fc4d1.png

Well I go to the next step and I click resume.

5a332056e50fe_2016-08-16(6).thumb.png.974c6abfdd3b3be321dd1381186e042a.png

The second problem happens now, the nozzle moves into position to the left front of the tray. I rule the bed with the sheet of paper and the adjustment screw.

WIN_20160816_09_49_56_Pro.thumb.jpg.091544594ca67c94b0e8e88576922c76.jpg

But the display screen, written Z = -14.09

WIN_20160816_09_49_47_Pro.thumb.jpg.b2e85d1ee906b65fdfcf19cc9c136d43.jpg

Then I click on the nozzle moves back to the bottom and center of the bed but at about 15 mm of the bed (Sorry but I kutch is a measure for the moment)

WIN_20160816_09_55_12_Pro.thumb.jpg.30c81470dda5a7b1e9347d350de0dd4c.jpg

And the screen written Z = 0.00

WIN_20160816_09_55_32_Pro.thumb.jpg.26398f0c969e1e355ceefd3177c8965f.jpg

Unable to set the bed, so I spend so the next step and click on resume.

And here the same situation, the nozzle moves to the front right of the bed but 15 mm of bed

WIN_20160816_10_03_19_Pro.thumb.jpg.aa3f516f7b4f83c4f30a639666ece7eb.jpg

And the screen also wrote that Z = 0.00

WIN_20160816_10_03_42_Pro.thumb.jpg.07031bd5351b625d3243d830f3f42f2a.jpg

The third problem is that the printer does not read the files, I put on the SD card, yet I are working with the Cura and records directly to SD card.

Thank you very much for your answer.

I'm not sure I understood everything, but I will try to follow the steps.

So first, I stop adjusts Z manually by putting the nozzle in bed center And bed 1mm

WIN_20160816_10_29_56_Pro.thumb.jpg.ffb52a05be5d518394b5ff66514d3353.jpg WIN_20160816_10_30_23_Pro.thumb.jpg.ebb99914e494f29fb347e54b43115140.jpg

Secondly I press the knob of the UltiController. And I'm going to prepare / auto- home.

WIN_20160816_10_39_45_Pro.thumb.jpg.1f1aa0b3810d04b2b87399711a6a00fd.jpgWIN_20160816_10_39_52_Pro.thumb.jpg.5bfd2f9dabb5b42d4fde3640b41c795d.jpg

The nozzle automatically moves to the front left of the bed

WIN_20160816_10_40_08_Pro.thumb.jpg.7cca2577703e3eddbc322d574df58665.jpg

I made him make a kiss with the paper to allow adjustment of the bed with the adjusting screw.

WIN_20160816_10_40_24_Pro.thumb.jpg.bab6ce57bddcba93c1ab7e7a8941883c.jpg

On ulticontoller Z = -14.09, Is this normal?

WIN_20160816_10_46_02_Pro.thumb.jpg.3f96f30e2c7f64ad78f352507669e5f6.jpg

Then this is where is not very well understood, I manually moves the nozzle to the bottom in the center. And after I press prepare / autohome?

And I repeated the action for the front right of the bed?

Many thank you for your help in finding a sollution.

Indeed that's not normal at all

Please could you try this?

Go to the Menu -> Control -> Restore Failsafe

Then do Home again and check if the screen still says Z -14.09

If that fails, could you try this?

Download the latest Cura version and update the firmware (just in case)

And if all that fails let's try this

Download Printrun/Pronterface software to connect from the computer to the Ultimaker with the USB cable

http://koti.kapsi.fi/~kliment/printrun/

Once you hit 'Connect' on the software the machine with do a 'ECHO' with a lot of info. Copy & paste that info here, that will show if there's any Z offset problem that can be reconfigured by Gcode.

Super this to work out. Now when I press prepare / autohome Z = 0.00.

WIN_20160816_11_21_03_Pro.thumb.jpg.74a0896e5c29e03824327d9e4732898f.jpg

So I repeated the action of kisses for each angle manually? (Bottom center and right front) and I press prepare / autohome between each corner?

No, after the home it's done, you should be able to move the Head with your hand. Move to the corners and adjust without the paper, looking that the nozzle almost kisses the bed.

Also, since the error did come back try again Restore Failsafe and after using it, go Save Settings or Store Settings (can't remember the name of the option but it's one of thoes). That should save all the failsafe settings, it's weird because if it worked before it should work again.

I think you have a M206 Z15 offset, or something like that, that could be because the Board at some point had UM2 firmware. Try that Restore Failsafe and Save/Store settings. That should fix the problem I think. If it doesn't, try the other steps, specially Uploading the Firmware again from last cura.

This time it to function well, after having been prepare / autohome.

I have pressed Control/ Restore failsafe and after I pressed Store memory.

I turn off and turned on the printer several times, and it does not seem to move at this time.

Did the SD card come with the printer? Can you reformat it? On some windows computers files may actually be:

a.gcode.txt

But when you look at it in windows it only shows:

a.gcode

Could it be that? The controller will only show gcode files.

Also a very common problem is that one of the 2 cables to the ulticontroller is backwards or loose. Remove and re-insert both cables (with power off!). If one cable is not all the way you will get these symptoms: everything works except SD card.

I turned off the printer. (I unplugged the sector) And I disconnected and reconnected the cables of Ultimaker controller. I turn on the printer. But that does not change the problem, I have even a new one.

Y stops moving !!!! And the controller still recognizes the SD card but does not read the files .gcode put on it.

Find someone with a working UMO - maybe go to the fablab in utrecht? Joris there can help you.  That way you can isolate the problem to either the printer PCB, the cables, the Ulticontroller or the SD card.  Once you know which of those 4 things that are broken you can replace just the broken one.

 

Great, I'll probably fablab in Amsterdam, closer to my home. Meanwhile I'll test the multimeter.

thank you
