Holes in ABS print
Hi, I'm trying to figure out some settings for using ABS.
Attached is a image with a simple 10 mm cube and disk.
The file was sliced in Cura to the right of the print I wrote down the Extruder temp, Bed Temp, Print speed, and layer size settings
When I got to 3rd one down,
.1mm layer at 220 extruder temp, 110 bed temp and 50 print speed I start to get holes in the print.
I thought maybe it was the filament I was using.
Shaxon Blue ABS, which I'll admit has gotten bad reviews.
So I tried a different filament, Black ABS from Prototype Supply.
*I painted the print grey so you can see the holes better.
I used the exact same file and got the same errors.
So can some one explain what is happening? Mostly this is just a learning experience fro me so I can learn to trouble shoot my prints.
Thanks.

I'm no expert myself, but even the best of those looks a little stringy. It seems like an extrusion rate or z-calibration issue; either way the printer needs to smoosh each layer down onto the one below it a little. I don't use Cura, but it would be helpful to know more about your hardware.

I figured out what the problem was.
Just a in case anyone runs into something like the above images.
Turns out my issue was three things things.
One was crap in the nozzle. I did 5 cold pulls and got that cleaned up.
The holes were coming from blockages in the nozzle.
The other issue was the bed was slightly loose.
One of the smaller screws that holds the heated bed to the laser cut bed holder had come lose.
I tighted them up and put a drop from a hot glue gun to keep them from vibrating lose again.
I was also trying out 3.0 Shaxon ABS from Frys.
I switched to ABS from Prototype supply and that seemed to print better.
Please explain to me how to...
