S Series Extruder Driver

The X-Axis driver on my FLSUN T1 Pro died after about 3 months of continuous usage. I loved the printer so much that I bought another one to fill the downtime, and it is a similarly great machine. I ordered several replacement drivers in case I got another bad one, and they are all a drop-in replacement and worked great right out of the box. You will need the old heat sink and a solvent to thin the adhesive FLSUN uses, or you will need to remove that adhesive and use something else. I chose silicon thermal grease and a dab of superglue on the IC closest to the square pin. So far so good.
