#Burning motors regardless of current setting and wiring. Solved:Failed to Configure Rsense

motors too hot: probably don't have num smart drivers set right in board.txt, uart pins not correct, etc.

#

you'll probably see that the "driver is not detected" in M122

#

m122 would help troubleshoot ye

ruby sparrow
#

what does the motor current report itself as? before the motors get hot and after?

#

seems like it isn't a missing driver, assuming you have 5 drivers

#

you have 5 and not 6 drivers, right?

#

drivers always "work fine" if they aren't detected as uart drivers

#

but they cannot be configured

#

so they will run at whatever default current is configured on the board, often too high

#

drivers will always work on step/dir/en & vmot

#

check M906 and make sure they always report the right value

exotic stirrup
#

can you post your config?

ruby sparrow
#

if driver 0 isn't detected, it will still work to drive the motor, but you can't configure it, so microsteps, current, etc. are all unknown/default

exotic stirrup
#

what 5160 drivers are they?

#

which mellow 5160's?

stepper.DriverType = {tmcspiauto, tmcspiauto, tmcspiauto, tmcuartauto, tmcuartauto, tmcuartauto, stepdir, stepdir, stepdir, stepdir, stepdir, stepdir, stepdir, stepdir} seems you mistakenly set driver0 to spi when it should be uart

exotic stirrup
#

you'll need to set the correct sense resistor then

#

no

ruby sparrow
#

I thought you said you have 6 drivers

ruby sparrow
#

ok, then port 6 is also not detected

exotic stirrup
#

the sense resistor value is 0.033

#

don't worry about setting the S value

ruby sparrow
#

@arctic field you have port6 set to stepdir

#

so if X is on port6, it is unconfigured

#

but I assume not, since 1 and 2 should be the 5160s

#

anyway, fix 6 as well whileyou're at it

exotic stirrup
#

all he needs to do is change the number of smart drivers to 7 not 6

ruby sparrow
#

and do the sensor resistor thing jay says

exotic stirrup
#

i've added a note to cover it on the wiki (as we don't currently)

exotic stirrup
#

the external ones definitely work with the correct sense resistor as i use 4 of them on my vzbot

#

what motors are they?

#

what current are you setting the 2804's at?

tardy echoBOT
#

GG @arctic field, you just advanced to level 4!

exotic stirrup
#

yea, i run them at 4A now with the mellow drivers and with the 1HCLs

#

fingers crossed!
