Raft hard to remove?

A couple things to consider: Ensure that your build plate is flat and level. An un-parallel HBP could result in the object "welding" to the raft. Turn down your nozzle temperature. It is likely that ...

Getting a Cura Raft to stick to the object more firmly (for ABS)

You should reduce the air gap option called "Raft Air Gap". Printing ABS optimally requires an enclosure of the printer, wind and draft cause temperature changes which could lead to layer separation.

What exactly does automatic bed leveling do?

Last first: use of a raft has nothing to do with bed levelling. It depends only on the features/shape/etc of the object being printed. Now, as to what the auto-levelling does: the answer is, sadly "...

What exactly does automatic bed leveling do?

Basically there are two problems to address: first - bed inclination and second - uneven bed surface. There are different algorithms dealing with one or both problems. Most specialists insist that ...

Lines of PLA not sticking to the bed

You got a few things happening. First that temp seems low. I am printing PLA at 215.. but there are a lot of factors. Start with a simple calibration thin wall test. Which is just a wall, no body. ...

What exactly does automatic bed leveling do?

A probe or even manual (e.g. through LCD panel) leveling results in either a reference plane or mesh. This depends on the firmware and the options set in the firmware. Basically, this process maps the ...

Why did my print fall off its raft?

Your trouble lies within the presliced G-code: the temperatures are rather low for PLA and upping both by 10 degrees would be advisable: 200 °C for the Hotend 60 °C for the Bed Atop that, printing a ...

Why did my print fall off its raft?

It looks to me as the model did not have enough surface contact with the raft. This can be caused by to big of a gap between raft and model set in the slicer or because of Underextrusion. The part ...

How should I go about printing easily removable rafts?

As comments suggest, a raft is not all that popular. Consider using a brim/skirt instead. I've had excellent luck with a 4-mm skirt, printing onto blue painter's tape. (Unless you consider it bad ...

Raft hard to remove?

You could try reducing the temperature of the hotend. If you are using too high of a temperature, the ABS will "run" and over-adhere to the raft. What slicer are you using? I have found that raft ...

When to use Wave Bonding vs Raft on a 3D print?

After additional research, it seems that using both at the same time is ill-advised (more like pointless). Wave bonding is best suited for larger prints, primarily to prevent warping of the initial ...

What tweaks do slicers use to get rafts to stick?

While using rafts with PLA is a good idea due to warping, PETG is a material that requires very little build plate adhesion. When I printed with PLA, I would normally use a two layer raft with a 0.3&...

Raft warping (Makerbot Replicator+)

How should I go about printing easily removable rafts?

My Hatchbox PLA filament only allows me to use rafts

PLA is a forgiving filament, you can even print such filament without a heated bed. Although there are differences in quality between brands, PLA shouldn't need a raft to be printed. Hatchbox filament ...

Why raft is printed much better than the actual first layer?

Based on the scarring and the appearance of the printed holes, it looks as if the nozzle to bed distance is not good, it is probably too large (could be too close as well, if you consider the scarring ...

Why does a raft reduce / limit build volume?

The raft still needs to fit on the bed, and it counts as a print, because, it is printed. You want the raft for better adhesion, so that means that you need more contact with the bed. If you’re not, ...

Why does a raft adhere to the bed while skirt does not?

The raft base (initial layer) is usually printed with very wide lines. Cura's default is double the nozzle diameter, so 0.8 mm with standard 0.4 mm nozzle. This is ridiculously high flow, especially ...
