BTT SFS V2.0 For Sovol SV07/SV07+

Update(#2) 2024-01-04: Filament guide to be mounted on top near spool holder added.

Made and tested by Tomas Olsson. 

----------------------------------------------------------------------------------------------------------------

Update 2024-01-04: New version of sensor bracket/holder.  Sensor can be mounted just above the extruder and move with the extruder. 

~shorter distance between sensor and extruder=higher accuracy. 

~Less sensitivity between filament path from spool. 

~lower false positives when filament reaches edges of spool. 

~can be used with lower length of bowden tube since it only needs to be between sensor and extruder. 

 Made and tested by Tomas Olsson.

Update 2023-12-25: Added pictures of wiring and extended cable harness for the sv07+

Thanks to @Pgain88_1484577 for the pictures.

This guide provides any necessary information on how to replace the standard filament runout sensor for a BTT SFS V2.0 smart sensor on the Sovol SV07 and SV07 Plus.

This was a project me and my friend Tomas Olsson Worked on together and i have full permission to post the full guide and files.

What you need

1. SFS V2.0
2. Printed part of couplerholderV0.3.3mf and SFSV2Holder.3mf
3. Tools

IF YOU HAVE AN SV07 PLUS, YOU WILL NEED TO EXTEND THE CABLE THAT COMES WITH THE SFS V2.0 OR BUY A LONGER ONE.

How to

1. Remove the button plate of the printer.
2. Unconnect the old filament Runout sensor and remove it.
3. Connect the SFS V2.0.

 

Run the SFS V2.0 wire where the old runout sensor wire is.

Mount the printed parts and the SFS V2.0

Add the button plate of the printer.

Start printer.

Edit printer.cfg

Remove:

 [filament_switch_sensor my_sensor]
 #pause_on_runout: True
 #runout_gcode:
 #RESPOND TYPE=error MSG="Filament Runout! Please change filament!"
 #event_delay: 3.0
 #pause_delay: 0.5
 switch_pin:PD11

 

Add:

[filament_switch_sensor switch_sensor]
switch_pin: PD11
pause_on_runout: False
runout_gcode:
  PAUSE #[pause_resume] is required in printer.cfg
  RESPOND TYPE=error MSG="No filament was detected!"
insert_gcode:
  RESPOND TYPE=echo MSG="Filament was inserted"
[filament_motion_sensor encoder_sensor]
switch_pin: ^PB14
detection_length: 3
extruder: extruder
pause_on_runout: False
runout_gcode:
  PAUSE # [pause_resume] is required in printer.cfg
  RESPOND TYPE=error MSG="Filament is stuck!"
insert_gcode:
  RESPOND TYPE=echo MSG="Filament was inserted"

 

Save and restart.

Check if its working:

Mainsail: Under dashboard you will see:

 

Fluidd: You will find it under the page "Tune"

 

If everything checks out try to print.

HAPPY PRINTING
