Unbelievable how much easier this just made my life. Thank you!
Another great video on something that has intimidated me for a long time jag you are great at explaining how to do stuff
Thank you 🙏🏿 this mean a lot!!.
Thank you! This simplified the process for me and helped me get this going on the first try. Been intimidated by it just reading the klipper docs. This explanation was WAY better.
Seriously, thank you.
Thank you happy I was able to help ☺️
Finally a video (actually it was 2) that is easy to follow and work along. I have not counted how many I had to go through to find this channel, but it mos def were more than a few. Thank you so much, I am in the process of starting the homing, i.E. the last missing piece (before, when I tried after watching the 1st video, it rammed into the wall)
I’m happy my videos was able to help.
Thank you, your video always have amazing explanations
Thank you bro!
Hi, thank you very much for the video. I'm from Brazil and I loved your didactics, very detailed for inexperienced people like me. +1 sub
great video, explained really well easy to follow , keep up the great work 👍
Glad you liked it!
Man! you are doing really great I have learned a lot from your videos
Thank you!! 🙏🏿
nice one! thank you!
Yo u doing it man ur the man great video dude keep them coming
Thank you!
thank you, worked perfect for me :)
You’re welcome
Pretty helpful video！
Glad it was helpful!
Have you tried adding a homing macro on any of your printers yet? The Voron printers use a homing macro that lowers the driver current on the motors, and it applies some other changes to the TMC drivers, which allows for the homing retract to work properly without the endstop error being triggered when it uses your standard TMC driver settings in the config. I am looking for a good tutorial on how to do this with TMC2209, but I cant seem to find any.
Thanks mate for the tutorial. Works fine on my X stepper, but with my Z still is not working! I need to do different configuration?
sensorless homing is not recommended for z axis.
Do you have to cut diag pins for Z axis and E axis drivers? I remember having to do this while configuring marlin way back..
also, do you need to specify diag pin and driver_SGTHRS for all axis that should have sensorless homing?
For example in the video the config does not contain diag_pin and driver_SGTHRS in stepper Y.
you with new board like skr 3 skr 2 and skr octopus board you don't need to cut the pin any longer..a jumper is used instead to activate sensorless home on the axis that It's needed on.. Yes you will need to specify a diag pin which is basically the endstop pin of the axis and driver_SGTHRS for sensitivity. for axes that are not using sensorless homing you wouldn't need any of the latter.
When doing the sensorless homing, is it just X that's sensorless? Currently building my 2.4r2 and learning as I go.
Nice, i will try this on my printer How does it work in a heated (60 C) chamber?
Hello. Why did you use stealthchop_threshold: 1? Looks like docs says it should be stealthchop_threshold: 0 to disable stealthchop
Very goog. Thanks
You’re welcome
lets setup senseless homing !!! great content you have helped me a ton one question i have is do you know how i can add a slider to fans in the mainsail console
you're welcome...which fan ?
Currently I am using spread cycle but do I need to adjust jumpers on board beside these tips? (fluiddpi +skr 1.4 turbo
No you shouldn’t need to for sensorless homing, you only adjust the jumpers to config uart mode communication for the drivers.
@@GoldenJaguar3D Thank you bro after my print is done I will try right away, I am sick of my endstop spring being to pop out
do i need to cut the pin on the stepper drivers or is that not needed in klipper?
yes you need the pin on the stepper driver, If you cut it sensorless homing won't work.
Hi, Thank you for the video. Very well explained. It would be much better though without that annoying background tune.
Hi I have followed your tutorial, even copying your settings from comment below and still not working, it is just crushing into side of printer ... Do I need to change something on stepper? Cutting/bending pin or something? On marlin with sensorless they worked fine (but to do so i had to cut of one pin from driver, is it a case?)
Hey sorry to hear about this man, but to answer you’re question, no you need the Diag pin in order to use sensorless homing, if you cut it you can’t use sensorless homing and will need to use a limit switch. So make sure that the driver your using have the diag pin intact and supports sensorless homing.
The file he posted below DOES NOT have any sensorless homing in it.
Okay, maybe stupid question here about the diag pin. I think you said your setup is for a SKR 1.4 and your diag pin is shown as P1.29 which seems to be the x-endstop pin. If sensorless homing means getting rid of the physical x- (and y-) endstops, why is it required to include the diag pin? Wouldn't that pin have nothing connected to it? I ask because I think I read somewhere about connecting pins with jumpers and that's kind of where I got lost. Otherwise I understand the configuration, makes good sense. Appreciate any response. I feel like you're going to answer and I'm going to immediately realize whatever it is my brain just isn't grasping right now.
Well the diag pin the located on the 2209 driver itself, it purpose is to detect stepper motor stall, in the case of sensorless homing where motor hits the side of the gantry. in your printer.cfg you're telling firmware that you're using a virtual endstop, just like you would for a z probe, but in this case its a pin on the driver (2209) itself. If you don't set a pin in the config. The firmware won't know where the senor is, I hope this helps. Pin P1.29 can be used as a physical or virtual endstop.
@@GoldenJaguar3D I think I get it. The diag pin is on the driver and I'm telling the firmware to take that signal and treat it as it would a signal coming from Pin P1.29 (aka, the pin that would normally be a physical endstop) so when the diag pin detects a stall, the firmware takes that stall and calls for the motor to stop. Hence, virtual endstop. I think?
@@phildawgydawg exactly you got it!!
Thank you for your good video, ı made your settings then X step working good but when ı make same settings for Y mainsail give me an eror, "pin virtual_endstop used multiple times in config" how can ı do it for Y too ?
thank you for your help
It’s sound like you have the same pin duplicated in your config make sure to remove the pin from your y stepper endstop since you’re going to be using it as a diag pin for your y stepper driver.
@@GoldenJaguar3D sorry can you explane more clear ı am not full control on this job :)
Works great for the X but just crashes into the Y no matter the sensitivity. Even tried swapping drivers. Any ideas?
what board are you using?
@@GoldenJaguar3D fysetc spider v1.1. Jumped the xy diag, removed the endstop wiring, and definitely using the right pin designations for the diag. If I switch the diag pin to have a ^ in front then the Y wont move at all
actually it says "By default, Klipper places the TMC drivers in “spreadcycle” mode." so spread cycle is enabled by default. you don't need to set it to 1 or 0.
you correct the website says that, but if you look it say to enable stealth_chop ad 99999 to the config the default config atleast for the skr if you go the driver section show 99999 which enables stealth_chop and not spread cycle mode, so it could some to report.
@@GoldenJaguar3D Current docs say to remove it:
> It is recommended to always use "spreadcycle" mode (by not specifying stealthchop_threshold) or to always use "stealthchop" mode (by setting stealthchop_threshold to 999999).
@@GoldenJaguar3D yeah depends on the config u downlaoded
Btw homie, stealthchop can actually lower your torque, especially if used in combo with pressure advance and raise heat while reducing that torque. Idk that you want to run stealth chop if you want max torque homie g slice biscuit
Love your videos, could you post your config so i could take a look please ?
sure I'll will uploading another video soon, I post a link to my one drive with all my printer configs.
@@GoldenJaguar3D hey thanks for the video! did you happen to upload your config file anywhere? I tried looking through your other videos but couldn't find it.

@@hunterfisher2304 ok take a look at this video, make sure you didn't cut the diag pin else it won't work. th-cam.com/video/zZYd0aYtThY/w-d-xo.html
Can you do this for z axis?
yes you can but generally its not recommended for accuracy, and could cause damage to your printer depending implementation.
can you share your printer config? I'm having problems getting things working.
Sure thing, I will when I get off work.

@@GoldenJaguar3D awesome man. thanks! I appreciate it. yeah i have not been able to get the inductive bed leveling sensor working with the skr 1.4 turbo. I'll check your config to see what i'm missing.
hey, was trying to get this going on a octopus 1.1 but i need to bring the print head back to middle of bed after each axis homes. I tried a macro but its not working. any ideas on how to do it? i tried the klipper example for x but after it homes x it just goes in a diagonal move and then tries to adjust bed, never even attempted to home. any ideas?
Hello
GoldenJaguar3D, could you pass your printer.cfg to check the settings? I'm having a problem that I can't do the home correctly, if you can pass it, I'd appreciate it.. a big hug.
