I don't know. Are the currently set the same for all drivers?
TMC5160 has given us a lot of problems.
https://github.com/bdring/Grbl_Esp32/wiki/Trinamic-TMC5160-Issues
all three are bigtreetech tmc-5160 silentstepstick. to see if it's the drivers i switched them around and still the same issue... the second socket runs 5-12 degrees (according to my ir thermometer) hotter. the jumpers all set to spi, and 5160 (over default) and 3.3v (over 5v). i will note that the last time i fiddled with the machine definition file i just noticed that when i compare it to the example on github that i left out
#undef N_AXIS
and the #define MACHINE_NAME did not match the name of the file... both of which i'm correcting now and will reflash.. i'm new at this and maybe been fiddling around to much.. but it doesn't inherently seem like something that would cause this issue...
as a side note i did just realise that my power source 24v 14.6 amps... that would fit the observations suggesting wierd behavior due to psu.... i will continue to reflash with the changes i made to the machine definition and see if the heating issues resolves itself. will also include the definition here in case u notice something that stands out. will report back

might you have a recommendation for psu's. maybe one that has worked for you? driving three 2.8amp steppers with tmc5160 drivers.... following the guide on wetterott guide for picking a power supply (https://learn.watterott.com/silentstepstick/faq/#how-to-set-the-stepper-motor-current) just curious is u have any recommendations.
I use a 24V 16A power supply. I don't see the problem, but I know there are people with 80A power supplies that do have the problem.
We really don't know why some people have problems and some do not.
Some people have suggested these protectors might work, but I have not heard about and test results.

so i got the motors moving and everything working ... you were right changing the psu did the trick.... (thanks to meanwell)... HOWEVER now that their moving they are ironically LOUDER than they've ever been before, i've tried both CoolStep and StealthChop modes with both waterott and bigtreetech drivers and still the same thing. i feel like there's something very simple in the grbl settings i'm missing... changing the step pulse does effect the sound that it makes, but not the volume of the sound... and i've tried literally every number from 10 -100. any suggestions...
because my steppers are 2.8 amps i'm thinking of trying the bigtreetech external 2160s 9https://usa.banggood.com/BIGTREETECH-TMC2160-High-Power-Ultra-Quite-Stepper-Driver-Compatible-3D-Printer-Parts-TMC5160-Motion-Control-p-1693831.html?utm_source=googleshopping&utm_medium=cpc_organic&gmcCountry=US&utm_content=minha&utm_campaign=minha-usg-pc¤cy=USD&cur_warehouse=CN&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgcs&utm_content=frank&utm_campaign=frank-ssc-usg-all-newcustom-ncv90-0420-19cov&ad_id=432153545270&gclid=CjwKCAjwnPOEBhA0EiwA609Ree1PA3keX1UHNfwEz_ACj8rhTvFDg40MSK1ElpzW7C_CHXhsdLC4UxoC6j4QAvD_BwE) tho that might be overkill rofl
What is the current setting for the 2 motors? The TMC2160s tend to be louder at faster speeds. Are they quiet with slow moves.
I have no experience with TMCxxxx external drivers.
lol i think i just stumbled onto the problem: current setting? are you referring to 0.75 for (X/Y/Z) RSENSE?

hmm thank you. i'm not sure how i missed these. i will read up and explore... i'll prolly have some questions but will see what i can solve first.
ok so i have $140/141/142=.250 (seems kinda low for 2.8 amp motors, shouldn't it be 1.4? $150/151/152=.125
$170=16 (if i'm not using stallguard at all what should this number be set to?
thank you again for your help.

u were right... it just needed some tuning and uping the micro steps... now she's a silent as a mouse 🙂 thanks again 🙂

everything seems to be running fine, but i've noticed that the 2nd motor socket (y-axis) seems run unusually warm. even when just powered on and not used it seems to 5-10 degrees warmer. intuitively that doesn't seem normal, what might cause that. i'm using tmc-5160 drivers on all three (bigtreetech)
