What options in cura would allow a skirt to print but not model

[theafterwar]

So I’ve been trying to print a model of mine for a week without any progress. My printer will not print my model. It’ll print a perfect looking skirt that’s been the easiest to clean from the plate so far but as soon as it starts the model it makes the movements but won’t extrude anything. Anyone have any idea what would cause this and how to fix?

Maker select v2

215 nozzle

60 bed

Is this PLA? If so, you are running kind of hot. It’s possible, and the is only a wild guess, that ‘heatcreep’

is occurring while the first lines are going down, but reaches the heatbreak and causes a clog pretty quickly.

Maybe try the same model at 195?

[Johnnyo1012]

For PLA we use a bed temp of 60 and extruder temp of 210.

Thanks.

[Andrew_247]

Give it a try at 195c and see if that helps. Oh, and check the fan speed in

your slicer settings. It may be set to be at 50% or off for the first few layers.

If so, then running at 210 or 215 may be too hot.

Again, only a guess.

Which Cura version are you using?

Activate the layer preview in Cura and go through it. Usually you’ll be able to spot the problem right away.

If it is not Cura, then it is something with your printer.

What filament type are you using? If it is PLA, have you had it out for some time? Is it brittle or does it breaks easily?

Check out this video first:

Also remember to cut off the serrated segment of filament when you reload it.

A good step is to use air and blow out any debris that gets caught in the feeder mechanism.

Well, it might not be the best help you can get, but if you send me the model I will try to print it (at least start) and see whether it goes beyond the skirt. At least that will tell you whether it’s a problem with the model file or the printer settings…or an incompatibility between both. I’m using an Ultimaker with Cura.

Take a look at your coupler maybe it is worn out. When your machine is cooled down the filament should move easily. When not it there could be a knot in the coupler blocking movement of the filament. You can also trying to move the filament in the maintenance menu

If your printer is working with other models without a problem, I could also imagine that your current model / STL has a defect or too tiny parts / walls which do prevent it from being printed. I recommend to do a quality/health check / auto repair (e.g. with Microsofts Azure online repair service) of it and also check for thin walls or parts.

[nilsmeulemans]

I agree, and that’s why I proposed to do a test print (or at least start one). I’ve been working with Cura for over three years and I’ve learnt that if it recognises your printer, it pretty much knows what can be printed and what not. It wouldn’t even start with the skirt if it’s not compatible. So, my guess is there is a defect with the file.

[3DAmsterdam]

You can find a lot of these defects in the layer view. When a component is to small or a wall thinner than your nozzle you won’t find it there.

Download a copy of Autodesk Netfabb. It is a great help in repairing defective meshes.

I suspect the model is up in the air, so before it prints, it prints the skirt.

You don’t see anything printed, probably because, you’ve disabled supports.

This is just a wild guess!

[theafterwar]

Thanks but I center it after every change and make sure there’s nothing lifted. Also my model has connected parts so i enable support.

[theafterwar]

Nice thanks I’ll try this when I get home

[theafterwar]

Awesome thanks I’ll try that.

[theafterwar]

Cool thank you how should I send the model?

[theafterwar]

It’s not brittle but thanks for suggestion. Everything is only a couple weeks old.

[theafterwar]

It is pla so I’ll try that thank you.

[theafterwar]

I tried that and it’s weird the layers all look great. Should layer view also show supports if they are enabled?

its the newest cura 2.x something.
