I am very active designing and building new, better 3D printers.

I don’t think there is any “Best” 3D design software for all purposes, just like there is no “Best” vehicle for all purposes. Some people need a truck, some a van, others a sedan, sports car or motorcycle. A lot depends on what you want to design. I do a lot of engineering and I want to be able to…

You should not use a relay for controlling the hotend (extruder) temperature. It doesn’t require very much current, so the MOSFET transistors on your RAMPS 1.4 board will be more than large enough to control it. The way an Arduino/RAMPS controls the temperature for the hotend is by rapidly turning …

If you’d like, my printers can print that in PLA. Where are you located?

Many aspects of your 3DBenchy came out well. I’ve found than thinner layer heights help, and good cooling is important. On my printer I have plenty of insulation protecting the tip of the hotend from the PLA cooling, and there are three small blower (centrifugal) fans to quickly cool the PLA. Her…

Have you tried using a different/better extruder? I’ve been using this one for the last year, and it has worked quite well: ArmDrive Bowden Extruder by ChiggerPepi - Thingiverse All of the parts are easily available. I use a Mk8 drive gear, which gives you 50% more torque and you can get on eBay …
