Need Retraction calibration Help

[buggy]

So currently I am printing out the hallow pyramid to try and calibrate my retraction when I noticed it was doing something weird. I have been searching for a little while with no results so I thought I would ask much more experienced Rostock maxers for imput. Each one of my pyramids comes out with like a squished tip.

Update - So Im still trying to calibrate my retraction and so far im having no luck. I switched to a different object to speed up the process and no matter what i change i cant seem to get an improvement on my prints. I started off at 0mm for retraction at a speed of 30mm/s on the move as a base. I then printed at 1mm, 2mm, 3mm, and 4mm till i didnt see any improvement. i then increased the speed to 40mm/s, then 100mm/s, then 150mm/s with no noticeable change. am i missing something? any suggestions would be greatly appreciated

It looks like your temp is too high. There is a great thread on this, calibration pyramid challenge. It has a lot of information on it.

I will definitely check out that thread! Currently I'm printing abs at 230 and 85 bed temp, I will lower the temp of the extruder and reprint!

Thanks for the interesting link, made for good reading.

Also note that some firmware (I know that Marlin does this) limits your retraction speed even if you have firmware retraction set to "off". Note that hitting "retract" in pronterface was NOT being limited by this firmware limit. Totally crazy, but I verified it twice.

I was running into similar issues, and solved it by:
1) Increasing retraction speed in the firmware. It was set to 25 mm/s. I bumped this up to 50, which made a massive difference.
2) Increasing speed of non-print moves. You want the head to quickly get to the next printing spot before it has time to ooze.

I have no strings or branches in my prints now, they look great.

Thank you guys for the information, i have had no luck improving my prints using mattercontrol with matterslicer so i thought i would give repetier host a try given that it was the software that was originally used. So far my prints have been turning out a lot better with regards to the stringing and blobs i was experiencing with mattercontrol.
