Mini Kossel Pausing on and off while printing with new firmware update
Upgraded my firmware to latest website version 2 days ago had horrible prints since. blobs all over the place. after checking everything and find that retraction wasnt the issue. i started to watch a whole print then notice the printer would stop dead in its tracks (ozze would happen leaving a blob) then kicks back into like. this happens for around half a second 2 - 3 times a layer!!
Iv taken a video of it happening and slowed down the moment when it stops then carrys on. not this is even while doing the skirt!!
iv reset eeprom, restarted a new firmware from scratch, lowered segments to as low as 80, tried a new SD Card, tried printing via repetier software with gcode on hdd. all with the exact same results!
code is being made using cura and the 3dbency model. which i have been printing for the past 2 weeks with no issues at all.
any ideas as im competly lost here guys and printer is unusable

iv just found month of arduino sketch from 09/04/15 flashed and working so far no issues.
im printing from SD card
LCD im using is reprap discount normal size setup with sd card (the common one)
im also using auto level and z correction but always have been.
i only upgraded to i could easily reverse encoder knob via website config.
interested to know if other people are having same issue or just me?
is there a way of seeing version number on dowloaded versions from website?
Back working on this again.
I found an old arduino sketch for my older firmware dated 09/04/15 from the website. flashed this back on and no problem at all.
just tried latest website code today and getting stops again.
has anything changed between those dates?
my next test is to try without z correction and see if that helps.
to note i am getting warning while flashign that in near limits of arudino board and may cause instablilty (not exact error!)
time to look into a 32 bit due i think
were can i find the move buffer count so i can lower it?
Thanks

Found #define PRINTLINE_CACHE_SIZE 16
Changed that to 14. still got a pause.
Then lowered it to 10 and still got a pause.
Pause is always in the same spot. and also i have now tried with 2 boards, ramps 1.4/mega2560 and now a rumba both with same results.
any other ideas??
I use cura for my gcode generation.
thought i would try slic3r see if i get same result. i didnt notice the issue. (i only ran for a while though)
here is Gcodes for both and also the STL.
Can someone have a quick look see if they can see an issue?
Cura gcode can be see pausing in the video at the top of the page. (to note video slows down to show issue)
