Unresolved 3 WEEK OLD Y RODS WORN OUT???

I have replace the bearings for the Y axis made no difference still getting a bunch of ringing.. I can actually see the bed shift when the y axis changes direction so i made a video of bed movement..

 

I just see you moving the bed. Do you have a video of it doing the shifting while printing? Mine has some play up and down when I poke at it as well. As long as you don't see it wobbling while printing...it should be ok. And I am sure you have already tightened down the pillow blocks. So not sure.

 

Yes it moves around when printing not to that extreme but still moves. i was getting awesome prints now every print has ringing thats why i replaced bearings but it made no change thats why i am thinking rods and yes i checked the blocks belt tension you name it i checked it!!! I tried to take a video when its printing but it doesnt show in the video

 

What do you mean by "ringing"? Because most of the issues I'm thinking about that have been described that way were solved by turning up the power that the stepper motors get so that they can stop the bed at the end of a high-velocity movement.

 

. Thumb is bottom of print

what print speed are you using?

Edit: Actually what is the temps, material, and software you are using as well?

 

I've gone as low as 30mm That's actually what that block is printed at

Hatchbox Pla 210 cura. I have been using all along this just started happening. One print was fine the next ringing after every corner

That seems right. I print my hatchbox pla at 200, but 10C isn't going to give you that much of a difference.

So was your decision to replace the bearings from talking to Robo about the issue, or was that just something you wanted to try? Asking, because I was wondering if you have been already working with Robo on this issue. Have you changed anything else around the time this started to happen? Reflashing firmware or anything?

 

on the picture, what side is the ringing on? Was it on the X axis sides or the Y axis sides? Is it on all sides, just one, two sides?

 

All four sides pic was right side

I have changed the firmware trying to correct the issue but none before it was working perfectly. I just figured I'd try the bearings. I was getting some squeaking from the bearings as well

I actually just bought a caliper so I can measure the rod diameter it looks and feels rough and scored so I figured I'd check it

Sooo i put in a parts request for the rods no questions asked they just sent them hummmmm

 

well, that is good. Be sure to test them for being straight and not marked up. I ordered some rods from them awhile back and it took 3 shipments to get it right. First were bent, second were marked up bad, but the third was just right.

 

Well I already put a request in for the fans because well listen to the video OMG loud. I went back and forth with the guy for a week before he finally shipped them

fans are just loud unless you invest in better ones like this brand. http://amzn.com/B009NQLT0M. The 25mm on the hotend is just loud. you can update that to a 30mm, but not going to get a huge difference. A lot of fan noise is from the PSU. Something like this, http://amzn.com/B007K2H0GI, will only ramp up the fan as needed instead of full bore all the time.

 

It's moaning when starting up bearings are shot
