How to level my heated print bed?

Greetings,

i seem to have the problem where the one end of the bed is lower than the other, Y axis i think, if you look at the picture, the lower end of the picture the extruded plastic is nearly round, and on the other end its very flat.

Is it even possible to level the printbed, the only thing i have seen that can be leveled is the extruder.

As i side note if i had bought this device locally in Denmark, i would have returned it, is simply too much hassle, i knew that there would be problems, and that is ok, now this bed that is not level is just another nail in the coffin.

 

Lasse, take a look at this:

This is the bed leveler that tesseract created. Since your Y is not level, print in an area where you think the Y is most level when you print this. You'll also need some springs. This lets the bed float and can be adjusted by adjusting the tension on the bolts.

 

Thank you Melody,

this replaces the 4 bolts with nylon standoffs in the sliding rails correct?

Yes, I believe so. Tesseract can better explain how they work since he made them. I haven't printed them since my bed seems like it doesn't need them though I've thought of doing the mod once my printer is up and running again.

 

That being said, its somewhat dissapointing to buy something and then have to print parts for it to make it work properly

One thing you have to remember is that 3D printing is still really in it's early years. We're not to the click-n-print stage yet. Plus there are always revisions and changes and the community itself finds better ways to do something. Nothing like Crowdsourcing

 

Just a side question, how is it possible for anyone to print in space? How would astronauts level their print bed? Which way is up?

all the existing hardware is used, Lasse. I recommend getting some metal washers that fit into the plastic pieces though, as the springs are VERY strong and could bite into them (unlikely, but it's good practice). You will also need a dial indicator and one of the printed out dial indicator holders.

 

Melody,
I did realize that i had to tinker with the printer, to make the prints perfect, but what i have seen so far is a disaster, for a commercial product. I have manged to print 1 thing, and that was rampant with "stringieness", things not sticking to the bed, if i drive the z axis up, the treaded rods look like they are spinning out of control, and quite often if im at 15cm it will unalign so that one of the hex nuts will come loose. I have to modify it to level it?
But anyway, i have contacted Robo3d for refund policy, i cant really live with the way this performs.

Well made for space 3d printers are a little more advanced than needing fine tuning like leveling the bed. They're much more robust but at an insane price tag.

Yeah my friend has spent well in excess of $500 on upgrades on their Makerbot Replicator 2. Every printer, especially now, has tons of issues, and if you can't deal with them then you're not ready for 3d printing.

 

I've seen automatic levers. Just wondering if it's possible to modify Robo3d printer to utilize such a mod? What would it take to have auto-levelling?

Marlin has autoleveling build in. You'd just need the sensor

 

brass or copper shim/plate is fairly cheap. The best idea I could come up was to some how lay that down across the bed, and then use the nozzle (which is brass) to touch/short out. then you'd know exactly where z-zero is. I think I saw a video of one of the machines doing that method.

How to program/wire for it. I don't know.
