Alright, so begins my journey! Last year, I got a FLSun Q5, it's a delta 3D printer. It was an open box customer return that was discounted down to Rs 10k. Looks like whoever bought it, didn't realize they had to assemble it, so they returned it. I was finally able to start using it a couple of months ago.
I don't know much about 3D printing or 3D printers, but I've been seeing them come up in my random browsing every now and then and learned that there are two types of people: those who like to 3D print things, and those who like to play around with 3D printers. Turns out, I'm more of the second than the first, haha.
But yeah, Deltas always intrigued me — I remember wanting one because it looked cool about 10 years ago when I had no idea about anything 3D printer related.
Here it is, I've some basic mods that I'll explain:
When I first started using it, I got a few failures where the part would just fly away, so I found this 18 inch by 18 inch shelving rack on Amazon and I'm using it as an partial enclosure. It was wobbly as are most racks of this kind but once I sealed up three sides with 2mm acrylic, it became impressively solid.

I'm drying dessicant in that photo. I've learned that I need a lot of it, everywhere, especially with the monsoon. So I leave it on a steel plate for about six hours with the bed set to 90° C. I'll come up with a better solution later, this works well for now.
I got the orange-green color changing kind, it's less toxic than the prettier blue-pink one. To recharge/refresh it, you basically need to warm it up to encourage it to release the water it trapped, here you can see it's been successfully rejuvenated on the plate sitting on a 90° printer bed, but there are saturated beads in the same environment:
Wild.
Before I learned about needing to dry filament, I had a filament jam in the extruder, which I disassembled and had a lot of parts flying everywhere. I had to get a replacement, so I got a transparent one from Novo3D for a few hundred:
This is a clone of the Titan extruder, and is the exact kind that came with the 3D printer, so I didn't need to change any settings to start using it.
There are basically two types of extruders, they're those geared things that push filament. This one is the Bowden type, named after the braking system, where a wire travels through a tube. It's usually considered less precise but allows for a lighter head, which translates to faster printing speeds. The other type is direct drive, that's where the extruder feeds filament directly into the hot end without a PTFE tube.
There's usually some slack in the PTFE tube with a Bowden-type extruder, and this results in imprecise extrusion. Youtubers recommend replacing the stock bowden tube with something called a capricorn one. I haven't been able to find that particular brand of tube. I found a lot of sellers selling regular PTFE tubes in blue and calling it capricorn, but they're not actual capricorn tubes
The difference is that the regular tube has an inner diameter of 2mm, which translates to a slack of 3mm either way over the length of a meter or half a meter with standard 1.75mm filament. I found a seller on Amazon selling a PTFE tube with an inner diameter of 1.9mm, which is what a capricorn tube should be.

Here's a close-up of the stock tube in the middle, an incorrectly labelled capricorn on the right, and the 1.9mm ID tube on the left:
The difference is almost imperceptible, but it's supposed to make for better prints.
Here they are with filament inside:
There's a larger gap between the inner wall and filament on the right two compared to the left one.
Lastly, the vertical spool holder got stuck a few times, so I looked for a solution and found that someone had designed a horizontal spool holder, and it became my first functional print:

I'll update again after I figure out a few more mods.
