Hall effect replacement
I bought this pcb to replace my faulty hall effect pcb. The new microswitch pcb works great and my machine is up and running. Great price and fast shipping. Couldn't be happier.

Very prompt. Items well packaged.

Chris at KB-3D is awesome. Hes been helpful with any problems which of all my orders so far, there have been 1 which in my opinion was out of their control. I got a rail with a knick in it. The packaging was ok and everything else was good. I'm guessing it got damaged by the manufacturer and it was not caught during QC. This issues got corrected right away and they sent out a new rail immediately. 10 out of 10 would recommend them!!

Ordered a Voron wiring harness. Product is great, very well made. Unfortunately, it took way longer than advertised shipping times and ended up making my own harness.

Great selection, has nearly everything i need for for my Voron printers. Had an issue with some connectors that I purchased awhile back. Emailed support, had a response in a few hours and the replacement shipped that day. Shipping for order is always super fast.
