Filament drive slipping??

[keukpa 5]

Hi there,

I'm not new to 3D printing (been printing for about 2 years now) but I am new to the Ultimaker 2, I thought the specs for this printer looked amazing, but as yet, I've not really had a decent print from it....

First I was having support printing issues now I'm having filament issues, there seems to be an intermittent clicking noise, only quiet and only when the filament is extruding, is happens when I manually extrude from the options menu and the rest of the printer is static....

So I'm guessing the filament isn't being gripped correctly....is there a way to fix this and prevent it slipping? The problem is when it's trying to lay the brim or skirt or the part the filament isn't being pushed through correctly and so causes the print to fail...

I'm printing with the roll of PLA that came with my printer (only had it one week) and printing at 210C

Many thanks,

Keukpa

Hi Keukpa,

It sounds like it's the tension on the filament feeder, there is a little screw visable as you look down on the feeder from the top, that you adjust the tension with, I would recomend Printing of the Alternate UM2 feeder by lRobertl as soon as you can, it is much easier to change filament and get good tension.

You may need to alter you nozzel temperature slightly and it may be worth trying the Automic pull method to clean. I usuall print PLA at 210 degrees Cent

Have a quick search for the link on maintenance and cleaning, if I can find it I will add it in another post.

Thanks for the tips Izzy, do you know where the new feeder model is available? On thingiverse?

Hi Keukpa, on YouMagine. Look for lRobertl Alternative UM2 Feeder, I got some slightly longer screws and made some small spacers as I made a change to the yoke, It's also worth finding the part for a guide on the bearing that helps prevent the filament from moving side to side. I'll try and add my modified yoke on the site too.

Roberts feeder really is the bees knees, also make a small knurled nut to cover the head of the screw to make easy tension adjustments. Happy printing

Thanks, I've now downloaded this and will see what I can do

I'll use my AMAZING Up! printer to print tho, as I've not had any success with my Ultimaker 2 at all yet!

It does look like the filament feeder needed adjusting, but just to check have you upgraded to the latest firmware and latest Cura?

Initially I could print the robot ok but when I tried to do something I generated I had all sorts of problems. Upgrading the firmware and Cura at Christmas solved them and with a good level bed Robots feeder was one of the first things I printed.

I've now changed over the fan case but need to find the correct settings for the fan speed, it is now printing the robots left ear fine but I need to get it right for the right ear which now has a problem but used to be fine

Thanks, as this helped me with an issue I started having with some orange PLA and was not sure which screw was the one to tighten.
