GeeekPi 5PCS TMC2208 V2 3D Printer Stepper Motor Driver Modules with Heatsinks, 3D Printer Motherboard Accessories, Replace TMC2100 for 3D Printer Parts

Great value set of stepper drivers. However, the chips are on the underside of these modules and on a lot of motherboards, you will be unable to mount the supplied heatsinks on the chips.

Does the job well!!

During the summer heatwave I fails to notice they were overheating and it really didn't give me change to realize the problem. The temp in the room was 5 degrees more than usual and they never work s the same. Had to swap them out for a better brand.

Printer: Anycubic Mega SWow, these are incredible. My 3D printer no longer sounds like a milling cnc machine.Some parts are so quiet that i started to trouble shoot my extruder as i thought it wasnt working but was just silent, i mean silent!Z & Y very very low key and x sometimes makes a bit of noise but really nothing.A few gripes. On my printer the modules are all inline side to side. These are a tiny bit bigger than the original and i couldnt get them all down fully, with each one resting on another at one end. Fortunately they have long legs and socket is deep so it still made contact.Secondly, you need to calibrate this but they dont tell which is the calibration point. Turns out its the top left of the four pads, where left is near the potentiometer and bottom is the txt “gnd”.For my printer you need to invert all the leads going to the stepper motors. This sounds both wrong and scary but it isnt.I would have preferred it they all slotted in flat , would have given it 5 stats but these are fantastic.
