I really appreciate the way you explain things. You explain the "why" and not just the "how." It allows me to understand why things are done, and not just blindly copy how someone did it without understanding. It's very helpful and valuable for someone like me. Thanks again.

You've got great timing on this series, as its been concurrent with me building my first DIY (and first Klipper) printer, the Rook 2020 MK1. There's not too much documentation, so thank you for your help! The Rook homes to the top left (eg. mine homes at x117 y131 and z118.7), so the movement in your macro moves the wrong way; all the way back to zero. Edit: I had some adventures trying relative positioning, then had trouble finding where the endstop variables were kept, but finally got there with something like this: {% set safe_x = printer.configfile.settings.stepper_x.position_endstop - 5 %} ... G0 X{ safe_x } F1200 Klippper is great, but every feature is an adventure!

I recently done it (X and Y) in my rebuilt Anycubic Mega X (bedslinger) with a Manta M8P+CB1 . Saved me a lot of trouble , as there were less wiring needed to be redone. As long as it is properly tuned, it works like a charm, I have never had a false positive on homing after tuning it properly. In my printer I´m running with 75 for SGTHRS on both axis, and 0.800 run_current on X and 0.850 on Y (it´s a big heavy bed, 300x300). Now I´ll do it again on my other printer which will be rebuilt (this one gave me a lot of trouble with the stock electronics, but it´s frame is decent enough for a rebuild), a Brazilian made CoreXY (Sethi3D Farm), which has a single Z axis (no need for dual drivers for that axis) and will be using a SKR Mini E3 V3 with a MKS Pi for running Klipper. Wiring first, then programming. Will use sensorless only on X and Y as well. For Z I´ll use a CRTouch. Your CoreXY-specific tips on this video will be VERY useful on that rebuild. It´s not something I´d recommend doing in a printer that has endstops working properly (if it works, don´t touch it is my motto, but I don´t follow it, I like to tinker, LOL), but when building a new one from scratch (or rebuilding one) it´s a very useful tool.
@ChrisRiley10 ай бұрын
Totally agree with you, it works great to make things simpler, but if it already had endstops I would use them for sure.

This method is detecting stalling on one stepper, but on a corexy machine movement in x as well as y will always require both motors to turn together. That basically will make correct sensorless homing less accurate than on something like a bedslinger or cartesian ...
@ChrisRiley10 ай бұрын
Agreed, core XY is always a little tricky to get consistent.

Chris, watching your videos is becoming a way to get a degree in 3D printing. Great video, but I'm still wondering about the advantage except for the reduction in wiring.

Helps to prevent breaking something if some wiring breaks on an endstop, something blocks your head from hitting it, etc

@ChrisRiley10 ай бұрын
Thanks Dave, I wouldn't say there is a really advantage to it with most firmware at the moment. What I do think we will see is crash detection. When someone make it easer to tune on a more broad set of hardware, we could use stall guard to recover from a crash that may occur.
@djmulder7 ай бұрын
I have a different driver but got this working.. but I'm not sure if it is set right. It does work and doesn't grind.. but it does hit the end of the gantry as with your Y.. but I have a TMC5160, and it's a difference of 5 = doesn't move and 6 = it hits the end. So I don't know how to tweak it more Tho you mention speed, which is a good point (although it's not superfast already).. I'll lower that for my next testing.
@ChrisRiley7 ай бұрын
Good to hear you got it working. Confirm your belt tension as well, that will change it a bit.
@djmulder7 ай бұрын
@@ChrisRiley thx, yeh got it working but didn't feel stable enough.. So just moved my XY end stops. Belt tension remains a mystery for me. Especially the ab belts (voron 2.4). I just can't get them tight or equal. Best I got is 90% on the tension tool on klippain. I wish there was a guide or tool to keep one of the belts tight while I can pull the other. I have a cnc tap and have to lock in both.

@ndupontnet10 ай бұрын
One thing I've observed with my TMC2209's is that the threshold is really impacted by heat. I'm not sure if it's the motors or the drivers, but after a print it becomes too sensitive and is not able to home properly. Although my sensitivity is quite hard with the hardware when homing cold.

Tell me Chris, the Skr 1.4 turbo board has no diag pins to jumper .. ? is this automatically done or do you have to jumper the endstop pins ?

Yes, on the 1.4 you have to cut the diag pin on X and Y if you DON'T want to use sensorless homing. If you don't it will conflict with the endstop pin/switch.
