Need Help, problem with Y axis

Finally I've successfully make it stick , thanks for this thread;
http://forums.robo3dprinter.com/index.php?threads/my-print-is-not-sticking.1171/

And now, I have problem with the Y axis,
My printer version was ABS+PLA with heatbed.
I follow the step-by-step instruction from the manual and try with blue PLA from the box, other than that just default setting.

I try with 15mm cube,
Everything just fine for few first layer, and the trouble start on upper layer.

Here some picture of my trial,


^1st trial of 15mm cube, Y axis (bed movement) seems not right.


^2nd trial of 15mm, stopped the works in the middle. Same problem with same shape.

Please help to solve this.
I'll update with picture while I keep trying.
Thanks
*sorry for bad english

 

Your pulley belt is definitely way too loose. Have you tightened it yet? Should be a solid pluck about it.

 

Thanks for reply.
btw which is pulley belt? how to tightened it?
Do you have picture?

But I think its not that, because the it fail with same sequence.

 

Look under your build platform and you'll see a belt running the length of the bed connected on either end with a loop connector.

In order to tighten the belt you follow this procedure.

- Mark the belt showing the current "End" point of the flap. This is important so you know how much to tighten it.
-Unscrew the belt mount loop bracket from one end of the printer.
- Remove the belt from the loop bracket
- Adjust the notches a few clicks in so that the belt will be tighter and reinsert into the existing loop bracket.
- Reattach belt mount loop to build platform and check tightness. Repeat until you get a solid pluck from the belt.


If the belt is very tight then there might be an issue with the pulley on the drive shaft, which requires removing the build platform.

 

Oh,found it.
I'll update later mike.
Thank you.

 

Also make sure the belt isn't on backwards, the teeth should go into the pully. (facing to the left of the RoBo.)

 

If you have problems with tightening the belt the last little bit like I did, I printed and used a belt tightener.

I was only having axis shift with multiple parts being printed where as one part would print just fine. The cause was the loose belt shifting during the rapid acceleration of moving from one part to the next and I had to tighten both the X and Y axis.

 

-Solved-

After tightened the belt under bed, wich not hard to do with explaination above (Thanks to senior member here ),
it goes nice and smooth.

I have my 1st print , a 15mm cube. I'll post it later after work. lol.

Now I fail my print on Mr.Jaws, the object was detached at upper layer.
Maybe I'll try painters tape+acetone and hairspray methods,
already on my shoping list tommorow. lol

 

Nice idea, will try later.

 

Just make sure you don't end up tightening it TOO much. I actually ended up having to back off the tightness a little bit as I was noticing the stepping have a little problem with movement in the middle of the axis. I backed off the belt one tooth and put the curved tightener back on and things seem to be happier now.

 

Adding some painters tape this time, way much better adhesion than before.


Now I try to print spool holder mount from thingverse,

I didnt manage to make solid wall, strong infill, and the top not covered.
I can crush it like crispy bread.

Could anyone willing to share slic3r setting while i read the manual?
A bit confuse here coz my english not too well. hehe
