[Best setup UMO+]

Hi mate, 

 

Thank you once again for your help. 
 

Right, so I’ve adjusted the extruder screw tensioner in to 11mm from the black part to the washer as you said.  
 

I disabled ironing but added 1 top surface layer.  And these are the results. 
 

I think this is probably the best print I’ve had from it as of yet!

It might not be the Z screw.  I see the pattern seems to match the X.  It could be you are retracting too much (or not enough).

 

With the feeder open (no pressure on the filament) tug on the bowden at the top of the print head and the top of the feeder.  The bowden should not have any play - it should not easily move up and down even 1mm.  Even 0.1mm.  If it does then you are putting the bowden in wrong.  For the head it's easiest to loosen the 4 screws a few turns, put the bowden in and retighten until there is no play.

 

If there is no play on either end of the bowden then use retraction amount of between 4mm and 4.5mm.  Don't go outside that range.  You don't want the filament to actually pull up out of the head - you want just enough for the filament to stop pushing so hard and rest on the other side of the inside of the bowden (at the top of the arc of the bowden).

Hi mate, 

 

Thank you, I'll clean the Z axis later when I get home from work. see if that helps. it is looking a little dirty and so I doubt it would hurt, I'll also check out the boden tube movement, although I'm fairly sure it's reasonably static. 

 

There is very little temp fluctuations. +/- 2 degrees C, at very most 

 

So within Cura, I changed some settings;

Skin and Infill overlap percentage (30%)
-Alternate extra wall (enabled)
-Compensate wall overlaps (enabled)

 

I got the results below. the sides are perfect, details are nice and crisp and no rough edges. 

 

Ironing wasn't turned on for this print, however I have a feeling it may have been on earlier prints, I noticed the top layer was set to 0 for some reason, I'll adjust this up and enable ironing, see what results this gives me. 

 

The top almost looks like it was under extruding, even though it was extruding perfectly for the rest of the layers as I stood and watched it. again, I think this is a setting I need to address, rather than a fault with the printer.

Hi guys,

 

So I’ve got this old machine printing, however some of the prints weren’t great. 
 

Here’s what I’ve done so far. 

I’ve put a new 0.4mm nozzle and ensured the feed tube is completely free. 
 

I’ve repositioned the X axis limit switch 5mm to the right as the nozzle block hit the frame. It now auto homes without issue. 
 

I printed a cube and it was leaning to the left slightly,  so I used my callipers and noticed the Y axis wasn’t straight, so undid and adjusted the truck to get it as straight as possible.

 

I’ve lowered the print speed from 60mm/s to 50mm/s printing PLA with temps of 60/200. 
 

I’m using cura and I’d prefer quality over speed, what can I change/ adjust to  improve the quality of the prints. 
 

I’ve also levelled the bed and used the paper pinch technique cura says. 

[IMO+ PLA feeding issues]

So I actually managed to solve this issue, it wasn’t really a problem, just doing it wrong. 

[IMO+ PLA feeding issues]

Hi All, 

 

I've very recently acquired a Ultimaker Original plus printer from a friend and I'm having some issues with the PLA feeder. 

 

I've used a brand new sealed reel of PLA, removed the bowden tube off the feeder and it still wont feed the PLA up, I can't even feel the PLA up using the manual extrude wheel.

 

If I apply pressure like in the first picture, I can manually feed the PLA through the feeder, however when I release the pressure, it no longer feeds. 

 

The little latch that comes down, should this hold the black part where the thumb is in tight or be loose? is this a friction fit part or does that just simply stop the black roller part on the pivot from dropping down?

 

Could the black roller ball be warn ( picture 2) enough that it doesn't contact the PLA against the knurled roller?

 

In picture 3, it shows the locking latch in a horizontal position, does this fit tightly between the two upright plastic parts?

 

Thank you all.
