I have had my Tevo Tarantula for quite a few years now. It was running a version of repetier. Finally I got fed up with manual bed levelling and decide to try out BL Touch. For that I switched over to Marlin firmware because this fine person has created a fork of Marlin with Easy Config parameters in configuration.h that allow you to setup BL Touch easily among other things, and sure enough it was very easy to set it up. I was so happy to get the Auto Bed Level working.
Here is the link to his fork:

However I am having one issue. My benchy is not printing well. It is very bumpy. I have tried several things including different slicers, different versions of Octoprint, different ways to slice it,old gcode file that used to print great in Repetier before BL Touch install, nothing seems to make any difference. It stays bumpy.
The only suspect now I have is Marlin firmware. After looking at it closely I see that the bumps are created by the small stalls during print. It looks like either the printer is exhausting the buffer and waiting for more from Octoprint (I doubt it), or something else is interrupting and it is going out and processing it while leaving the nozzle at one place (more likely) causing a bump due to melting and oozing of filament.
I am attaching picture to show what I mean.
Hopefully one of you experts out there can help me out. The print looks very ugly and low quality.
I also tried increasing the BUFSIZE to increase the serial buffer to 16 from 4, but that didn't help either.
