Review on 🔄 BCZAMD 3D Printer Z Axis Upgrade Parts: T8 PTFE Teflo Lead Screw, Extended Length 367Mm/ 14 by Tropingzz Cece

I was so happy to get them. I bought 2. Both rods are connected at each end. Replaced 1 and the one sent was worse than. The one that needs to be replaced! Upon further investigation, I found that there were spots on each end of each lead screw that were not teflon coated or defective. Not sure why all three different leadscrews have it, but all three leadscrews had issues. In the photos below you can see what I'm talking about. As the light reflects, there are clear spots where bare metal is visible. socks. I was so excited about that. I think I'll have to shell out a few more bucks and get it from Misumi or McMaster-Carr. If this company doesn't send me 2 threaded spindles without defects, I won't buy anything from them anymore.
