LGX Lite configured (by default) to run HOT (out of spec)
https://www.bondtech.se/product/lgx-lite-large-gears-extruder/
Recommended stepper motor Current (using LGX Lite) : 0.45 to 0.60 AHowever, RatOS configures it quite a bit higher at 0.707: https://github.com/Rat-OS/RatOS-configuration/blob/v2.x/extruders/lgx-lite.cfg https://github.com/Rat-OS/RatOS-configuration/blob/v2.x/steppers/ldo/36sth20-1004ahg/24v-0.7a-e.cfg

It's identical to the 36sth20-1004ahg that's used on the Orbiter 2.0 where people are complaining 0.707A is too low (it's not).
0.6A on the LGX is sad performance.
I generally don't really care about manufacturer configs, i care about the motor specs and configure according to their rating. If you want lower current it's just 2 lines in the user override section away 🙂
🤷♂️
hhelp pls. if i dont put stepper config for lgx lite motor in the printer.cfg than its 0.5a? Because its in vcore3 config 0.5.
2. question:; why in steppers config extruder stepper has 64 microsteps but bontech say 16 microsteps is right. 64 microsteps can heating stepper motor more??
yes
64 microsteps can heating stepper motor more??No
bontech say 16 microsteps is rightThat has nothing to do with their extruder or their motor lol.
This is comically wrong
Bondtech has marlin brain, don't pay too much attention 🙂
It doesn't say that you're required to use any particular amount of microsteps. Thankfully. That would've been embarassing.
interesting. thank you.
1 more; this meanmeans, 0.707 rms is 1A motor peak?
indeed 🙂
