How can I adjust bed level along y axis?

Hi guys - just received my Robo3D and have been playing with it today. I've noticed that the bed seems to slope down to the front (along the y axis) and would like to adjust that. Anyone know how? I think that is the reason why my prints are coming out looking 'twisted'?? X axis appears level...
Any suggestions/help appreciated

I got the springs off amazon. Not sure where you're located though

Thanks for your reply. I'm in Australia. Is there no adjustment already built into the printer? Problem is I can't print accurately until the bed is level. At the moment, prints are coming out looking "twisted" up the z axis.

can you share a picture?

 

This is a print I tried yesterday and killed part way thru. Printed the 5mm calibration block first and it looked fine though...?

Heres an easy way to make it quickly and easily adjustable...
Remove nut under standoff, replace with rubber oring and metal washer. Now the oring acts like a spring but is very solid and doesnt wobble.
Tighten to lower it....

 

Ok Racegrafix I can give that a try. Not sure whether it will give me enough adjustment tho. It's out by a few mm front of bed to back

What I did was left from stock and just did the rear, and fine tune it from there. You could always add another washer, those are typically 1mm.

It may not be the best method, but its a 5 minute fix that's very easy. Bed is still as solid as ever, and super fine adjustments are easily done as well as bigger adjustments.

 

Ok I'll head off to Bunnings (local big shed hardware) and get supplies to give it a try. Will report back...
As a newbie I'm interested to hear opinions on my diagnosis that this issue is the cause of my "twisted" prints...?

If i understand what you are trying to print, from the photo the gears are meant to be twisted. I would view the stl and confirm if it is designed that way

 

OMG! How embarrassing! Would help if I looked closer at the STL - d'oh!! Thanks scotta you are correct that the gears are meant to be twisted. Still think I should make sure the bed is closer to level across the y though...

Hi all - thanks so much to all who responded to my post. My Robo is now printing beautiful PLA parts for me. I followed Racegrafix suggestion as I had some washers & o-rings etc handy. Worked well - so thanks again. Now to try ABS.......

 

Awesome man, glad it helped out. Its nice when something so simple works.

 

Hey guys - I'm baaaaacccckkkk! Seems my bed is unlevel again?? Going to try the bed levellers this time as I printed them off when the printer was going fine. Just wondering if anyone can help me with a description of the bed screw. Mine are not long enough for the bed levellers, so will need to get some new ones, I'm just not sure what to look for (i.e.. diameter of the screw is...?)

 

Check the flatness of the bed. I went around and around till i figured out the bed was not flat. Tightening the belt below it will help true it up.

 

How "violently" do you remove the printed piece from the bed? I made the mistake of getting everything perfect level, did a few very nice prints, then, in a fit of impatience, tried to pry off a piece that was stuck hard to the bed. I am sure I pushed the rails out of alignment with the pressure and lost my level. I am going to try the vinyl suggestion which would allow me to pull off the whole print rather than wait 30+minutes for the bed to cool enough to pop off the piece.

 

Can someone post specs info on the screws, nuts and washers. I will try to get them online. Thanks!

 

Mcmaster part #
91166A210 - washers
9262K161 - orings

use the nut without the nylon insert that's on your bed now, and the same screw. You could always add another nut on top to lock it in place, but there is enough tension on mine that it doesn't back off. And of course still use plastic washer on top of glass.

those orings will work, not sure if its same exact same height. If you need more height just add one more washer, don't think you will need to though.

 

Thanks a lot Racegrafix!
