Did you bother to contact their customer support asking if they plan to add this feature?
In my biased opinion, I would imagine Gmail would want to use you and your emails for every ounce of data they can squeeze out of it. However proton is a paid service who doesn’t sell your data, with much less Human Resources than google, therefore less language support. They add things as fast as they can get around to them. If you inquire they might be more apt to add the support if they have someone on staff that can do it.
The implication is that if you want something of quality you are going to expect to pay for that quality.
If it’s cheap then corners were cut. Several years ago the tech was just as you described. Not perfect. I bought an ender 3 pro and it wasn’t perfect. I sank a lot of money into it to get an “acceptable” result. It sounds like you selected hard-mode and chose a Delta. I can’t imagine what you went through. I hope you’re ok.
I recently got back into the hobby, and decided to spend more for a better quality printer. Prusa was the Cadillac back when I was toiling in Ender upgrades. What I have found is that newer printers and and slicer software have made a drastic leap forward. Things are markedly better all around.
I chose Prusa, but it was a tough choice. I probably would have been just as happy with Bambu, but I would have paid more.
Based on my journey I suggest you spend more for quality. Right now that’s Bambu lab and prusa. Prusa is behind, but the customer service is there. Bambu is going through some legal troubles, so that is something to consider.
I think because it’s been a a minute since you’ve dabbled you’ll find things have improved. Maybe don’t buy a delta. The Prusa MK4s bed slinger is the fastest bed slinger. The Bambu core XY is faster and comes with an enclosure. Prusa just announced a Core XY but it wont ship for months and it has smaller in build dimensions.
As far as budget printers go, I haven’t wasted any time looking into them. I wasn’t gonna mess around and find out this time. Maybe there is something out there that would make you happy, but I’m not going to gamble and suggest one.
