Ultimaker 2+ problem Please help!

Posted · Ultimaker 2+ problem Please help!

I received my Ultimaker 2+ about 10 days ago and I have a seriously annoying problem. For some reason I'm getting these weak layers on my prints, almost as if its skipping layers. It's incredibly frustrating and I'm trying to get a print done for a deadline but I can't if i have these weak layers. its Completely random and doesn't happen at any specific layer height every time.

Here are some photos of the problem: http://imgur.com/a/jsBis

Did you have a look at the link?

There is one specific case where reducing the Z current helped, maybe that's your problem?

On the Ultimaker 2+ the current to Z is already set at 1200mA instead of 1300mA, so I don't think that could be the problem.

Have you tried adding sewing machine oil to your Z-shafts? If the bearings aren't riding smoothly on the shafts, that can contribute to your bed not moving well. I recommend adding a drop of sewing machine oil about 3/4 of the way up the Z-shafts, and then using Maintenance --> Advanced --> Raise Build Plate a few times to make sure it's evenly spread.

Weird. I did that two weeks ago but since there's always people saying that the z shafts shouldn't get any oil ever... I spread some sewing machine oil on a microfiber lens cleaning cloth then clean the z shafts with it. It works quite nice, but it won't revive any bad long bearings. Also it won't cause any z problems. I did too that Z raise, by hand with the machine off, a few times.

In my experience, oiling the Z-shafts with sewing machine oil is absolutely as important as keeping the XY shafts oiled. I wouldn't recommend the Teflon infused lubricators, but, I use sewing machine oil regularly.

It won't fix the bearings if the bearings themselves are bad, but if the shafts are too dry, they won't run as smoothly as they should.

I use Ballistol which is available on the web and a first class oil - only needs a finger dipped in the end of the bottle and spread over the bars etc to provide first class lubrication.

Used on guns etc., doesn't wax up and first class - Have a look at the specs :)
