SV08 BLTouch/3DTouch Probe Mount

A BLTouch or 3D touch probe mount for your SV08.  

Do NOT use the 24v power pin on the connector and use an alternative 5V pin.

It will require a modified toolhead cover to allow for the fit as it sticks out the side. Use my alternative Toolhead cover. SV08 Minimal Toolhead cover with LED by EternalGnome | Download free STL model | Printables.com

change the x offset to 20.5 mm, and the y offset to 6 mm

Print with high temp ASA, ABS, or PETG.

Use a few M3 screws and nuts. 12mm, 6mm and 8mm.

Standard version is for the stock standard length (28.2mm) nozzle as well as the Hardened steel nozzle

Shelf version adds a small nut shelf to make it easier to install.

Let me know if you need a shorter or longer one for other nozzles.

After installation.
Turn on your printer, BLtouch pin should self test.
Edit printer.cfg
Comment out the [probe] section

Add [bltouch] section (change values as needed):

[bltouch] 
sensor_pin: ^extra_mcu:PB6
control_pin: extra_mcu:PB7
x_offset: -20.5
y_offset: 6
z_offset: 0
pin_move_time: 0.8
speed: 2
samples: 2
sample_retract_dist: 5.0
samples_result: average
samples_tolerance: 0.100
samples_tolerance_retries: 2

comment out [z_offset_calibration] section, as it references probe in the python script. (I haven’t figured out this part yet, so we will manually configure z offset)

delete the [probe] line from the saved config section at the bottom of the config section.

Save and restart

Test Probe Commands:
BLTOUCH_DEBUG COMMAND=reset
- To reset the probe if it errors and starts blinking
- 
BLTOUCH_DEBUG COMMAND=pin_down
- The pin should go down.
BLTOUCH_DEBUG COMMAND=pin_up
- The pin should go up.
- 
BLTOUCH_DEBUG COMMAND=pin_down
- Bring pin down
BLTOUCH_DEBUG COMMAND=touch_mode
- Change to touch mode
QUERY_PROBE
- It should return “open”
<touch the probe to bring it up>
QUERY_PROBE
- It should return “triggered”. (3DTouch clone always says “open”, but it still works)

Get your finger ready on the emergency stop button.
Run G28 to home.
When the pin goes down, touch the pin to bring it up. 
- If it stops, then it is working
- If it doesn’t stop, emergency stop the printer, or shutoff the printer before the head crashes into the bed.

PROBE_CALIBRATE 
- To manually calibrate the zoffset using the paper test.
SAVE_CONFIG
- To Save

TROUBLESHOOTING:
Probe Doesn’t deploy properly with the cover on: the lower left magnet of the cover is interfering with the bltouch. Remove this magnet and try again.
Probe z offset changes every time you home: your bltouch is not accurate. Knock off 3dtouch has high variance.
