Crazy wobble!

Hi,

I have now had my printer for a couple of days and I can't really figure this out. Most things are working well. I have printed a spool holder, I installed the XXL controller and I printed some Z-axis stabilizers. I don't have any problem getting the print to stick, hair spray do the trick. I have printed all kinds of stuff, long things, small things and round things. Only once did something warp from the bed.

I do, however, have crazy wobble problems. It's so bad that at this moment I don't really have any use for the printer. I need this to be sorted out.

I'm a total beginner at this and only have very basic technical knowledge, but I do think I know where some of the problem is. My threaded rods moves A LOT. They move so much that they still move the smooth rods even though I have the stabilizers. Sometimes it wobbles so much that everything gets stuck. They don't look straight at all. I took a video of it:



At the end of the video you can see another weird thing. My power button stopped working. When I try to turn the printer off it just springs back! I have to unplug it to turn it off.

Here are some prints. I use Cura, 195C, 35mm/s. The unfinished one is 0.1 layerhight, the middle is 0.2 and the last is 0.2046. Not much different to the waves. I tried MatterControl but it just makes a horrible mess of everything. I also tried different speed and temperatures but this turned out the best.



I would love to hear any tips! Thanks!

 

Your threaded rods don't seem centered in the groove. They seem to move in an oblong circle.

 

They also sound like they need a little lubrication.

 

Definitely need some white lithium grease or other lube for the threaded rods to calm the squeal. (found at hardware stores or auto parts stores)
I have not been able to get a good balance with the stabilizers in place. For starting out I would say leave em off. They are mostly for when you need to print really high and the jerking is intensified, like closer to max height. for prints under 4-5 inches or so, I would debate that they are less important.

 

Also, try printing some of the bottom smooth rod z stabilizers from tesseract. I'm not sure what r3d is sending out now, but mine were both teeny and broken. My threaded rods move around quite a bit as well, but I'm getting very good results despite this. Here is the .stl for the z stabilizers:

 

Thanks for all the tips guys!

Today I went straight for the store and got some white litium grease. Worked great and my printer sounds great!
When I was at it I decide to pick up a metric rod and nuts too. Makes sense since I'm Swedish! Changing out the rods felt like big job considering my experience with this stuff, but what did I have to lose?

Changing the rods went well and the waviness went down a little bit. After that I flashed the software and panic struck! My printer didn't work at all! After some reachers on the forums it turned out I used the wrong version! It wasn't adapted for my newer model with auto bed compensation (did I use the right term? ) and after flashing with the right one we were back on track. A couple of calibration cubes and changes to the code I am now at a result I'm very happy with! All the axis are within 0.5mm. I will try to get it even better another day.

Here is before and after:




Looks amazing to me!
Only problem is my power button who still springs back when I try to turn it off. Tomorrow I will turn the printer up side down to see if I see anything out of order. Anyone have any idea of what can be causing it?

Again, thanks for all the help! Without this forum I would be lost!

AWESOME!!! Really glad for ya! Nice lookin' cube.

 

The power switch has a spring inside on the rocker arm. More than likely it's popped off.
You should be able to remove the switch from the power/fuse block. Not sure if it's sealed or if it comes apart.
The Robo guys should be able to mail you a replacement. It's a quick enough swap.
