<p>I'm trying to set up a Creality Sprite Extruder on my Ender 3 Pro without using the kit (installing the extruder alone).</p>
<p>I can see <a href="https://store.creality.com/products/sprite-extruder-pro-kit-300%E2%84%83-printing?official-website-top=&amp;spm=..product_0f7e137a-4505-43ca-958f-022f372863a0.products_display_1.1" rel="nofollow noreferrer">here</a> that the extruder operates at 1.4VDC and 0.8A.</p>
<p>I'm using TMC2208 and Klipper. How can I set my extruder's driver up so that the provided voltage is 1.4V? Is it the same as setting the VRef to 1.4V?
Can it be done in the Klipper config (I have UART set up) or does it need to be done on the trimpot?</p>
<p>Thanks</p>

I found that mine being in an enclosure caused the hotend to not cool sufficiently, so I had to lower the hot bed temp by 10 degrees and that seems to have resolved my issue for heat creep. I also have the Hero Me fan housing which improves airflow.</p>\n"}]
