Review on Pack Of 5 TMC2208 Stepper Motor Drivers For 3D Printers, DORHEA V1.2 Module With Heat Sink And Screwdriver For RepRap, RAMPS1.4, MKS, Prusa I3, Ender-3 Pro Controller Boards by Bart Schwalbe

I'm using mine with an Anycubic Mega S. They work great. So much quieter. I waited a couple of months to install them as I wanted to be confident in the printer and my own ability. It was pretty easy. I did wind up using some other "low profile" heatsinks (spare raspberry pi kit) instead of the included ones as they were too tall for my fan arrangement. I do recommend upgrading the driver fan. I set the VRef to around .85 volts from the factory 1.1 volt. You can attach the leads of your meter with alligator clips to ground and the adjustment tool and measure and adjust the voltage at the same time as it is present on the potentiometer. The stepper motors run cool with no missed steps.Prints are as good or better. I notice a slight change in the interference pattern created by the print head motion in an otherwise smooth surface on a calibration cube. That makes sense with the step interpolation. Otherwise I can't tell a difference. It's astounding how much it changes with the same motors just using different impulses. Not sure why they don't use them to begin with other than a bit more cost. It's now a better printer. *UPDATE* I eventually switched them from Legacy mode to UART. It's tricky to solder the three little pads, but I got it done. It's definitely worth the effort if you feel comfortable performing the modification.
