Warning: Driver 1 warning: over temperature warning
-
I have my two Z axis wired and correctly configured to run off of Driver 1 (light Z stepper/ystep) and Driver 2 (left Z stepper/ZA) ((DUET2WIFI)). I am getting a "Warning: Driver 1 warning: over temperature warning." I don't know what additional information is needed to troubleshoot. I have checked connections, ensured both lead screws can freely rotate and I don't know what else I can do. Any help would be greatly appreciated.

@SonnyD1 did you feel the stepper driver heat sink to see if it was hot?
-
@moth4017 Yes and it did not feel hot to me.
-
@SonnyD1 post your config

@SonnyD1 what stepper motors are you using the current looks high , try dropping t0 1200 ma
-
@moth4017 It's the LDO-42STH47-2504AC rated at 2.5a max current. The 2300 your seeing is around 80% of that. 1200 would be less than 50% max current. Should I go that low? The driver is rated for 3a right?
-
@SonnyD1 Do you have any 'active cooling' for the stepper drivers on your Duet 2 Wifi? typically with motors that use higher currents (like the motors you have) it is recommended to have fans blowing air over the Duet boards to cool the stepper drivers/chips. The TMC2660 chips heatsink to the board itself.
-
@sebkritikel No I don't. Ive never needed it on other builds. Is that the only thing that will resolve my issue?
-
@SonnyD1 i think the drivers are rated at 2.4A peak not continuous ,
-
@moth4017 Based on 2.4a peak what % would you recommend. Usually its between 60-85%. I can drop em all down I think. Especially since its not a speed printer. I'll give 75% a try.
-
@moth4017 so I lowered it to 1900. Repeated the G32 that was triggering the error and it completed this time. I'm pretty sure that will be enough current. If not, now I know I will have to add additional cooling to the boards. I may end up doing that anyway. Thank you for the help but I think you've solved my issue for now.
