Welcome to the SeeMeCNC Community

Without going into a very long story, after about a year of messing with my printer I have finally been able to print something. I calibrated per the instructions and ran some additional calibration tips I found on the net specific to the Rostock. I ran the small cube test and had pretty good results for a first print, but it looks like I need to fine tuning. I have included the cube print as well as a partial calibration print. If you look at the cube you can see that on some corners it seems to overshoot the corner and bulge out instead of making a clean corner. In some cases the bulge is only on one side of the turn and not the other. In other cases it is on both sides and in one case the corner looks perfect. I was pretty happy with the print as I had no strings or very few imperfections on the walls. I assume this at least means my retraction settings are pretty much perfect.

After the cube print I found a calibration file specifically for delta printers and gave that a go. I stopped the print after a few rounds. I highlighted what looks like thin areas where I believe the head is too high. At least I think it's too high. So my question is where to begin fine tuning? Since I am new to 3D printing can I get some somewhat detailed help (ie. explain it to me like a noob).

Some info
.91 firmware
Printing ABS
Head 230 (E3D not stock)
Bed 95
Default Repetier first height and subsequent height


*edit
Also the print seems to just quit LCD says KILLED. The timer reached zero and it just dead stops. It's seems to be right at the end of the print. Maybe 2 layers left. When it does I lose all control of the printer. I can't send any commands at all they just queue up. I have to disconnect the printer from the laptop and reconnect. This seems to be a wide spread issue after some searching, but I don't see any solution.

your printing in abs... get the blue tape off and use the purple elmers glue stick, put it on cold, if you do it hot you use too much glue... hot end 240 bed at least 90'''' you see where your thin spots are in between the towers, looks like that is a horizontal radius calibration problem. go back thru the manual procedure's and re calibrate. do it EXACTLY as Gene Describes using rep host. I had to do it 4 times to get it flat.

the corners being blobby was for me an extrusion problem, I lowered my extrusion speed to.95 and it cleared it up, calibrate your extruder also

Took me a year to get mine working also...

That was going to be my question. Whats up with the tape? Chuck it. It for unheated beds.
