Review on Enhance 3D Print Quality with the Zeelo TL Smoother Elimination Clipping Controller by John Clark

I typed at normal speed for about 15 minutes and my extruder motor started clicking. I ordered 2 packs for a total of 6 units but only received 5. So far X, Y and Z seem fine but the extruder started clicking and not working for some reason. I checked the temperature and surprisingly X and Y were much hotter than the extruder so I don't know what to do about it. At this point in time, I cannot say whether this has had a positive effect, as I have not carried out any calibration tests. If I see better quality I will increase to 3 stars but for now they are not very good. There aren't any instructions either, so not sure which way to plug them in, nor sure about the cable pinouts as they aren't supported. I'm using MKS GEN L with A4988 drivers if that helps.
