MS Learn is pretty good. Apart from that MS has youtube channels like Microsoft Azure or Microsoft Developer. From paid ones Udemy courses by Scott Duff (mentioned by Sander Rossel) is not bad to give you advice what to look for. I would advice to start with learning paths for AZ900 if you are new to Azure as you will not know what is what and then start exploring development like AZ203(old)/AZ204(new). There is also big community on like groups e.g. MeetUp.com or similar where you can attend free workshops led by MS professionals for free.

I'm technical person and I playing with 3d printers for 4 years..(not that I want to show off but to give you a reference to my comments). First question that you need to ask yourself is how much do you really want to spend on device? Second is do you like to tinker(as this is your hobby) or you want to have working device right of the box? Depending on your answers.. if you can afford kits >1000$ so anything is good. If you want to spend 500$-1000$ probably Prusa MK3 is the natural choice (you can save a bit buy buying DIY kit) or pay a bit more for assembled one. Of course market is big and you can spend on something else but Prusa is a BRAND and they have a support and big community behind this. 200$-500$ probably anything from better known Chinese brands like Creality, Tronxy, JGAurora, Tevo or similar check Youtube for the more popular guys how it looks.. Under 200$ Ender3 is the king.. And last 2 quick comments.. 1. don't be greedy.. 3D printer is slow process going big(big printer is a problem if you don't relay print that big prints) small printer are faster to use for small bits.. and big printers are slow for small prints and it takes ages to print a big print. There is a reason why most popular printers are below 300mm. 2. good heated print bed with autoleveling is the key with "extra" print surface which saves you ton of failed prints. Everything else these days are extra features that makes life a bit easier but are not that important. Regards Maciek
