Sensorless Homing - Skr1.4 Turbo and TMC2209

I'm going to have another attempt at getting Sensorless Homing working on Marlin version 2.0.5.1 using Bigtreetech TMC2209 stepper drivers on a SOVOL-SV01 3D Printer

Let's get together and see how it goes on livestream! :)

Thank you! :) I've been pulling my hair out trying to get this to work on my new CoreXY. Setting the X_CURRENT & Y_CURRENT to 200 stopped the grinding. I really wish others would be as thorough as you. It pisses me off that none of the 5 or so tutorials I watch gave no indication to the homing current as a possible issue. THANKS AGAIN!!!

Thanks for the two video streams for customizing marlin with the skr 1.4 and tmc2209 on the sovol.

Is it possible to get your firmware files as a base for me?

I plan the same setup for my printer.

Hi, I have just started going through your other video on the SKR 1.4/Marlin set up. Did you know that you seem to have disabled commenting and saving on that one? I would love to save it to study later.

hello - hoop alles gaan goed - im from George - hi - after spending 3 weeks struggling with my slow compiling vsc, finally i got to the point where i could power on everything via octoprint and get started only to find that octoprint cant locate the serial running everything through a pi4 so my setup is as follows: power comes in via the relay connected to the pi4, also using a buck converter to supply usb power to the pi4 - i put in the sd card with the firmware.bin, powered on the skr1.4 via octoprint, conected the printer to pi4 via usb, but octoprint cant connect as it cant locate the serial port - ANY advice would be appreciated - many thanks (using uart 2209 drivers)

i have a question, my sensorless homing is working on x and y with tmc 2209's in uart. i have 2208's in z and e0. why can't i unplug my endstops? they are removed from x and y, but once i unplug them, sensorless homing stops.

[stephenkosloff]

so got a new skr1.4turbo and now its working - all except my homing etc - using bltouch (switches on and moves up and down and tests)

Thanks, this is exactly my setup, on a Taratula Pro. Are you going to github the step by step, and maybe your config file? Thank you

No matter if i go from 10 - 250 my y axis stutters at the maximum I cant figure out of im going past a sweet spot as theres no change up or down

So I'm scratching my head, trying to setup homeless sensing with a btt skr 1.4 turbo and using btt tmc 2209s. X homes fine using sensorless homing but y always shows triggered even when you first turn on the printer? Diag pins are connected for both x and y and it does see my drivers

[stephenkosloff]

HI - GR8 VIDEO - im stuck, help my asseblief - cut pins on z and e0, but my x runs off against the lhside and grinds when i home it - im trying to set up sensorless homing - thanks

in my marlin screen appears "tmc connection error" do you know what that means? it's a 1.4 skr turbo with tmc 2209 1.2 drivers
