So my 3D printer uses two 10mm rods for the X axis with LM10UU bearings inside the toolhead carriage.
The regular metal bearings are quite noisy and have nasty resonance effects at 40mm/s speeds. They also have a lot of wiggle room.
In an attempt to solve this I bought the plastic variant which has no moving parts and just slides over the rod. They are too tight however and my printer struggles with moving in the X direction.
Does anyone have experience with these? I assume the plastic ones wear out over time so the friction should go down.
I got rid of mine and replaced it with an induction hob with power management. This way it can run on just 2.5KW but also on 7.5KW. Depending on your electrical connection.
I’ve found that 2.5 is plenty for me. No reason to change the electrical wiring.
It’s so much more pleasant to cook on than gas. It responds faster and also the cooking fumes go into the suction hood rather than all around it.
Gas produces a huge extra volume of combustion products and that ruins the efficiency of your ventilation system. Never mind the toxicity of the combustion products.
