Sorry if this is a duplicate but I couldn’t find anything so I figured I’d post. Redirect me by all means if someone else has posted something related to this problem.

I made my first two prints today on the A8 and they turned out awesome. One was the chess piece pre-loaded on the card, and the second was an upgrade off thingiverse. I noticed on both of them (and on cura for the third print I wanted to start) that there were these totally awkward and unnecessary bases that did nothing but use my filament and my time because I had to pick them off with a knife.

It’s like an extra perimeter’s circumference on my first print about 2 or three layers thick, and you can see it on the two tips of the glider in cura. I have no idea why it’s there, I have printed this glider before on a school printer and it never printed these. I’m using the exact same file, and neither of the three prints require supports. Any Ideas?

Hi there,

It sounds like you might have “raft” turned on in your slicer, which would cause an extra 3 layers to be printed before the part begins.

Best,

thanks for leaving the post.

I have just printed my first item and my second.

The only problem was the ‘raft’? (is this the flat base that surrounds the whole piece that has to be peeled off when complete?)

If so, while it was doing this in both cases it would do a small part of the surround and then go to either the left or the front edge and back to the printing area. I did this at least every circle of the print area and usually it only got a quarter or 1/8 of an inch before it went to the edge. It looked as if it was losing its place and just checking. Sometimes it didn’t even print any more just went back to the edge and returned

It was no real problem other than the fact it was extruding a little all the way and eventually got caught in its own trails. I kept cleaning it off but I am sure it shouldn’t have been doing that.

When the item started printing for proper the ‘hunting’ stopped?

I quite liked the ‘raft’ as it made it easy to remove from the bed.

Is it possible I could have the machine running too fast and it loses its signal?

I am using the cura program to run the printer.

In Repetier it says the receive cache size is 127 and somewhere I read if this is too fast take it down to 64. I can’t find this reading in the cura software?
