There is Cura-slicer, Slic3r : are there other slicers that anybody here tested?
Will the Prusa branch be ok for a delta printer like mine?

I personally have only used Slic3r.  It has done what I needed to do (mostly) and was easy to learn. 

As for the Prusa fork of Slicer being suitable for a delta, I don't really know.  Josef Prusa's justification for forking Slic3r was to be able to provide a slicing solution to his customer base that was pre-tuned for Prusa products.  Considering that, I question if it would offer delta users any advantage.
On the other hand, gcode is gcode is gcode, right?  Aside from the hardware specific codes of course - Obviously you aren't going to take gcode sliced for a Makerbot and expect it to work well on a MK2/3...

My first attempts at benchy had a really severe step like the one you pictured.  I blame the slicer.  I was using Slic3r 1.3.0 
I downloaded the Prusa fork of Slic3r (https://www.prusa3d.com/slic3r-prusa-edition/) and the problem went away (or at least became significantly less severe).

I'm really digging the Prusa Edition of Slic3r.  It improved the quality of all my prints, and has already configured settings (or at least a really good framework) for my MK2 clone. 
[...]

My suspect is also Slic3r, since the step is not there when printing with Cura.
If I find time (as soon as laptop is ok and after my holidays - these are holidays with wife so no robot or 3D stuff) I will try that.

Please do not be offended.
not at all bud, am just teasing. I do see there seems to be focus on 3DP with RR which is exacerbated  by the 3D junkies amongst us  :-X .  I personally think it about the best machine a hobbyist robot builder can have around, they aint overly noisy, not really messy either and far better than bashing balsa  :o, there still bashing and filing with 3DP... still its a prototyping production machine/tool which seems to get lost in the hype. best of all though, there becoming ever more affordable.

hope the move goes smoothly,  there aint a maker group close by start one! communities/world needs more of them.

I am using A4988 stepper drivers, which are rated up to 35V, so no issues there.  At the moment, I am using them "out of the box" - I haven't looked at/verified/touched the current limiting pots.  None of the steppers are skipping steps or overheating (although the Y-axis stepper seems to run a little warmer than the others), so I haven't felt the need.
     its well worth calibrating those drivers you may well get away with it for now with short 30-60 min prints, but that Y axis will/may jump up and bite you in the ass on those 5 hr print.
   you read triffid hunters calibration guide and driver guide ?

 you made belting progress,

you compared the speed setting with prusa and your standard slicer. suspect/thinking you got a little over extrusion going on, causing the ribbing and the prusa slicer moving slightly faster which in turn is  stretching the filament. giving the smoother finish.

        I drop the E/step in firmware ( by 20 increment ) down side to this is, could get a great wall and crappy top finish. (so dont go to far!).  the most sane approach!  with slicer is to tweak the Extrusion Multipliers, think they in the PRINT SETTING> ADVANCE  dont really use slicer that much these days. and haven't really tweaked those setting. so cant be much help here, but thats where i start with slicer

ps
 I drop the Z hop, just adds time to a print, but if you gonna use it, check out some of the acceleration related to it may reduce the noise. Auto bed probing over rated,  if you ask me and given how close that probe is to the prints, I be tempted to move it off the carriage and mount on the frame, use it as an endstop on the Z axis,, mount it so it triggers of the x axis bars.

as for 24V think you be the first.  most here are 12v so some of us be interested to see how that works out for you.

I now have the MKS GEN L 1.0 board up and running on 24V, using a 360W PSU.  Zero issues; everything seems to be working great. 
I am using A4988 stepper drivers, which are rated up to 35V, so no issues there.  At the moment, I am using them "out of the box" - I haven't looked at/verified/touched the current limiting pots.  None of the steppers are skipping steps or overheating (although the Y-axis stepper seems to run a little warmer than the others), so I haven't felt the need.
I am using a 40W 24V heater in the heat block which pulls less than 2A , so the extruder MOSFET isn't struggling at all; The heated bed is being driven via an external MOSFET board, so I can't comment on the bed MOSFET's current carrying capacity, although there again, at 24V the current is half what it would be at 12V, so I can't see it being a problem.
I have two 24V fans, a part cooling fan connected to the JST FAN connector and controllable through M106, and a heat breake cooling fan connected to the 24V JST connector that runs all the time.

I don't know what else to report - It all seems to be working just fine for me.  If anyone has any specific questions regarding using the MKS GEN L 1.0 at 24V, feel free to ask!

I'm really digging the Prusa Edition of Slic3r.  It improved the quality of all my prints, and has already configured settings (or at least a really good framework) for my MK2 clone. 

It has Z-hop on retraction enabled by default, which has remedied the issues I have been having with my inductive Z probe hitting my prints and knocking them loose from the build plate.  And yes, I have it raised up as high as I can get it and still have it trigger.  I suspect its lack of sensitivity range stems from the fact that I bought the absolute cheapest one I could find ($2.39 USD shipped) from AliExpress.
I may play around with the Z-hop settings though - the default Z change is 0.6mm and it's set to do it on any move longer than 1mm.  It's quite noisy.  Thinking I may drop it to like 0.2mm and require a move that is equal to or greater than the horizontal distance offset between the nozzle and the probe.

Hi Jinx,
Please do not be offended.
There is no doubt that changes in technology drive development and that coding and bots that were once the domain of Nerds and Professionals are now primary school projects and (hopefully) we'll all be better off in the future for this. I have to declare that my original training was in valve technology (yes I'm that old) so I've lived through one or two paradigm changes.
The capacity for 3D printing to realise innovative design realisation by everyday "makers" and for it to facilitate as yet unimagined electro-mechanical creativity is (IMHO) a very exciting unfolding frontier.
As far as my ongoing "building" is concerned.... It's all "on hold" pending change of residence to an apartment. The plan is to join a "Maker" group when we shift in about 6 months and once again I'll have access to a lab and might have enough grey mater left to dream up some devices to amuse myself with the help of even more powerful magnifying glasses.
Happy building.

Hmm I also see this step in the side of your boat.

Although not as visible like in my case.

Did not find time to find out where that comes from (broken laptop and too much work).

Got the beast up and running today, and after much tweaking and fiddling, managed to produce a pretty nice looking benchy!
