nitehawk SB printer.cfg changes and sensorless homing
I've been through the discord, and searched through the forums, but couldn't find an answer, so here we go. I am working on getting my voron 2.4r2 up and running for the first time and trying to configure for sensorless homing while using the nitehawk SB. I started by using the guide for the nitehawk straight from LDO found here, which leads to the GitHub repository here. Those instructions involve creating a file called nitehawk-sb.cfg and then an include in the orignial printer.cfg file that points to it. The nitehawk-sb.cfg file makes some changes to the printer.cfg file for proper operation (which I'm all for!) However, when researching where to put the jumpers on my octopus to allow sensorless homing I came across this article on the Vorondesign.com page. That article clearly led me to which jumpers to use, but it also indicated that I have to make changes to the printer.cfg file or "..YOU WILL BE SAD." These change are "mostly" already put in by the nitehawk-sb.cfg file, but there are some notable differences. For example. The VoronDesign page says to: If you have a [safe_z_home] section, find it and comment it out as we will be using homing override as found in homing.cfg. Which I did, because the nitehawk instructions don't inherently cover sensorless homing, but then I get to the Stepper_X instructions in the VoronDesign (I'm using 2209 drivers) it says: Updating stepper_x Locate the [stepper_x] section Record the current value for endstop_pin (PG6 for example) Change the endstop_pin to tmc2209_stepper_x:virtual_endstop Change homing_speed to 80 Change homing_retract_dist to 0 Locate the [tmc2209 stepper_x] section (usually right below where you just edited) Add diag_pin to match what you recorded from step 2, but add a ^ before it. Example: diag_pin: ^PG6 Add this below the diag_pin entry: driver_SGTHRS: 255 pretty straight forward it would seem, except the nitehawk-sb.cfg already made some changes (basically steps 1-3) but it had set homing_speed to 100 and the homing_retract_dist to 5 (I updated my file to follow the vorondesign instructions). The nitehawk-sb.cfg file had already found and moved the diag_pin to read " diag_pin: PG6 " instead of " diag_pin: ^PG6 " and it has the value for driver_SGTHRS: 60 instead of 255 as in the VoronDesign instructions. Looking ahead to the rest of the instructions there are similar disparities. So..... now I've stopped. Does anyone have advice on which settings to use and why? Anyone that has a similar build/setup please move to the front of the line But anyone that has good advice is welcome. -

Milo V1.5 CNC Bench Mill - Water Cooled - Casa Enclosure
Machined a plate in the dead zone for the 4th Axis. Still need to wire it up to Scylla and once it's squared up, two 6mm location pins. I also had to remodel and print a new X motor end plate. Had to shorten the top flush with the extrusion.- 3
