Optional – Install A Tough Dual Drive Extruder - Creality CR-10 S5 Complete Setup Manual

When the firmware is successfully flashed, the new name of the printer will be
displayed, which will indicate the new firmware is active. New menus will be made
available in the navigation tree, like "bed leveling", and a BLTouch menu among
other things.
A comment on my Bed Levelling parameters:
At the beginning I was probing 3 points only, and I was doing this at the beginning of
every print. I soon found it inaccurate as well as time consuming. My strategy now is
to probe a 7x7 grid for a much more accurate mesh, store it in EEPROM and do it
only periodically (like after re-tightening the bed spacers, or when resetting the
firmware). At the beginning of every print, I insert a gcode sequence after homing to
reload the mesh stored in EEPROM and activate bed levelling based on the stored
values. This works very well and enables a faster start of the prints (especially when
bed is pre-heated already).
Gcode is (pending the mesh has been saved before):
G28 //homing
M501 // restore EEPROM settings
M420 S1 // activate bed levelling based on current mesh
Optional – Install a tough dual drive extruder
After having changed all the parts above, and created a very robust printer, I ended
up with another frustration when I got prepared to print bigger parts. When loading a
big and heavy roll of filament on the filament holder, I noticed in some occasions that
the extruder was not capable to pull on the filament hard enough to assure the flow
expected. This ended up in grinding of the filament, which in turns made the extruder
pulley more slippery. I therefore decided to invest into a "tough extruder".
As for the fangs and ABL probes, there are many models and this document is not
intended to make any comparison. I purchased a BondTech BMG extruder that I
installed after printing the bracket available on their website (including a holder for
the stock filament detector). I'm sure the E3D Titan extruder is equally good.
Once the extruder is mounted on the bracket with the stock motor, I recommend the
following actions:
a) remove, if you had installed it, the holder for the bowden tube mentioned earlier
in this document. The other cable holder should be in place for the black cable.
b) zip-tie the black cable of the print head, as well as the BLTouch cable,
somewhere on top of the new extruder,
c) the bracket being made of PLA, the stepper motor will get hotter than before,
therefore install on its right hand side a 40x40 heat radiator with thermal glue
d) verify the good functioning of the filament detector and plug it back
e) verify the whole path of the filament by inserting a sample.
