I have managed to figure it out after lots of trials. I changed the g code flavour in repetier to reprap volumetric and it worked, but I wanted to used simplify and simplify does not have that flavour. In the end I don't think it was the communication or flavour(even though that worked).
Since I am using a direct drive extruder, my feedrates are much slower than most and so I turned down my max feedrate. Later on I found out that it was pausing becuase it was indeed retracting, just very slowly. So I changed the retract settings and nothing changed, finally I figured out that the max feedrate is tied to the retract feedrate, this cuased it to retract faster and not pause.

Re: Delta printer pauses
Interesting to read.. I recently had a very similar experience with a new CR-10s, using Simplify3D 4.1 when I changed my nozzle to 0.2mm.
The printer would pause for about 8 seconds intermittently, it seemed, and creating blobs that would ooze out from the extruder during the pause. At first I thought it was an overheating issue, ie the cpu would overheat and make a pause in order to cool down to execute the next command (I had this issue on a resin printer recently, and it would simply pause until it was cool enough to continue). I tried everything - mounting extra fans, removing the covers over the inlets , changing the internal fans etc, but nothing worked. I spent 2 days doing this.
After a while I started noticing that if I let it print a couple of millimeters high, it always paused in the same spots on the outline (a circular form), and when I looked closely in the slicer render, I noticed blue dots here and there in the slicer. What I have found to be the problem, is the slicing in Simplify3D. Some kind of bug creates a close to zero speed dot where the printer will pause, ooze out some plastic and then continue. That's why there are no issues in the G-code, no issues with overheating, voltage drops or any of the other things I tried.. The issue seems to lie with Simplify3D slicing and creating the near-zero-speed dots for print, and I believe it's the support-slicing that bugs out when the details become too small somehow with the 0.2mm nozzle. Will get back if I can supply any new info on the matter.. In the meanwhile, it would be great if an S3D-moderator had a look at it too.. Let's hope they read it!
