Hello
update:
no (original Case)
last night my CR-10 gets upgrade to DuetWifi
first the Duet needs FW upgrade…via SD an PC...
(comes with old FW)
then I'm creating the config via reprap online config
https://configurator.reprapfirmware.org/
for Molex Connectors you need a Tool for Crimping
looking amazon (DE): IZOKEE Crimpzange
works good for this cheap tool
the Duet fits into the original case of CR-10
without Display - mounting duet board with ca. 3cm distance from case, for air flow
using the 2 Case original case fans parallel
(using PWM Fan Port 3 - needs other PWM Frequency ~ 30Hz on 40% - so duet remains below 30 degrees)
for Bed using original Mosfet from CR-10
raise up Voltage on Powersource to 14.4V - works
(more Power 
)
first Test:
I'm using demo config files for prusa from sd,
then overwritten with data from config tool (zip)
I need to switch direktion for x, y Motor
Endstops working
in Bed conf there was a failure with Z define 2mm to low - correctet to 0
(I'm still work without autolevelling on CR1-10)
using 16 microstepps with interpolation for x,y,z
using 32 microstepps with interpolation for E
Test…with 100mm/sec - silence !
really silence - great
now i can hear the bad chinese ball bearings !
there is one bad bearing on Y
the fans are the only loud sound
very smooth printing
and testet...150% works...200% works
I let the printer print at 300mm/sec ! - with PLA
(needs 230 degrees and 150% extrusion - not nice, but works with original Hotend)
but up to 200mm/sec would be ok for Vase Mode
my CR-10 mods:
- Bed isolation - silcawool (stoutwind) 300x300
(sealed with a lot of Kapton) - more Voltage - 14.4V
- Fan Mod thingiverse : www.thingiverse.com/thing:2274499
(bridging without any problems) - Case fans, Hotend fan and Parts cooling fan on PWM Ports
(Hotend Fan working over 45 degrees) - BuildTak direct on ALU-heatbed (glass plate is too heavy for high speed)
- extra Car Fuses for Board (10A) and Bed (30A)
- CR-10 case and frame grounded
files, config will be submitted later….
