Thanks for this. I am on a Mac so this tip will help a lot when I finally get around to printing.

Once you have the printer up and running you will quickly learn that its all about how the first layer of the print sticks.

If the first layer is good you can usually be confident that the rest will be fine (very important for long print runs).

I usually watch the first layer very carefully as sometimes bits may stick together or some stray filament will get caught up and join with the part it its printing. These kind of things as quite common as when the printer first starts it takes a little while for the extrusion to become consistent.

This is where the extra loops help.

You may occasionally still get some bits that do not stick properly and start to cause havok. You can remove these if you are quick with something like a pair of tweezers. Otherwise filament will start balling around the nozzles and it will force you to cancel the print.

The other thing I found is that it does not always matter if a small part of the first layer support structure is missing. This will depend on the model but in in the case of a small part not sticking I watch the next layer. If it looks fine then I let it carry on. For example this happened on my WW1 tank in my prints thread and had not real effect on the outcome of the model.

This is not specific to idbox but to all the 3D printers of the same type so you can see a lot of people discussing similar points around the internet.
