Sovol SV06 Plus Eddy Mount

I do not recommend this product in its current state (01/09/24). 

Update: There may be a issue with eddy style probes on a bed this thin; I believe many of my issues were related to EMI/noise from the bed heater being on. I recommend setting the target temperature to 0 when probing by using M140 0.

 

When this probe works, it generates great first layers. When it doesn't work, troubleshooting is difficult even with the help of the Klipper Discord community. 

If you are going to attempt this, watch out for old guides written for the BTT fork of Klipper and search through the  #leveling-sensors channel on the Klipper discord for useful nuggets of info. 

One of my pain points was caused by running on RPi2 - this is a bit underpowered for this style of probe resulting in timing issues. Follow this guide Timeout During Homing/Probing | Esoterical’s CANBus Guide but assign 2 cores to Klipper instead of 1:
[Manager]
CPUAffinity=0-1
  

[Service]
CPUAffinity=2-3
  

 

SV06 Plus Mount for the BTT Eddy Probe.  

• The probing point is in the same position as the original sensor.
• This is not compatible with the original part cooling design.

 

I recommend using the following for securing the cable:

 

3* Ribbon Cable Guide
Sovol SV06 Plus mainboard extruder cable support (remix)
SV06 Extruder Cable Support
Sovol SV06 Print Head Cable Hook + BTT USB Cable

 

 

Offset:

1.66-1.79mm offset depending on the measuring point.
