### Basic Information:

Printer Model: Vcore31  
 MCU / Printerboard:Octopus Pro SHT42  
 `klippy.log`

_Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_**. _Pasting your_ `printer.cfg` _is **not** needed_  
_**Be sure to check our [Knowledge Base](https://klipper.discourse.group/t/about-the-knowledge-base-category-table-of-contents/6228) and in particular [this](https://klipper.discourse.group/t/how-to-trouble-shoot/6326) and [this](https://klipper.discourse.group/t/how-to-ask-for-help/6327) post**_

### Describe your issue:

I have a RR Vcore 3.1 enclosed  
As an extruder I am using an Orbiter 2 connected to an EBB42, but for some time I have been experiencing temperature problems, the Nema 14 motor of the extruder gets very hot, I don’t know exactly the temperature, I do know that you cannot touch it with your hands , and stop extruding.

I have tried to lower the current to 0.40, and with this something better, but even so it continues giving me overheating problems.

The engine is: LDO-36STH20-1004AHG(XH)

and the configuration I have for that motor, the one for the extruder is:

[tmc2209 extruder]  
uart\_pin: EBBCan: PA15  
run\_current: 0.40  
stealthchop\_threshold: 0  
interpolate: True  
sense\_resistor: 0.11  
driver\_TBL: 0  
driver\_TOFF: 4  
driver\_HEND: 6  
driver\_HSTRT: 7

I’m not sure that the “driver\_…” lines are correct.

Do you see anything that can be changed to prevent it from overheating?

Hi,

I’m looking at options, meanwhile I’ve put a fan with plastic flanges… An option that I do not know if it would work is to place instead of a fan as in the PCS, a Peltier sheet …

What do you think?
