| Jul 6, 2020 at 0:12 | comment | added | Faraz Ahmed | I am aware that kinematics are not the only variable in a perfect print but having a solid base does help a lot and simple tweaks and hacks can be done afterwards. These cheap printers are great but need a lot of babysitting to work right. I'm planning on making a minimal maintenance printer (fingers crossed) | |
| Jul 5, 2020 at 23:52 | comment | added | R.. GitHub STOP HELPING ICE | For example, see the 0.0125 mm positioning example in my self-answer here: 3dprinting.stackexchange.com/a/12075/11157 You can clearly see that the positioning is fine, but even with tuned linear advance etc. there's some bulge at one of the corners due to extrusion-related issues that better positioning won't help with. | |
| Jul 5, 2020 at 23:45 | comment | added | R.. GitHub STOP HELPING ICE | I'm not sure if this is entirely agreed upon, but I think it's largely the case these days (even with cheap printers like the Ender 3) that print precision is limited more by extrusion (accuracy of filament diameter, extruder stepping granularity, errors due to compressibility of filament, material oozing in the wrong place, etc.) than by axis positioning. In other words, to be able to take advantage of better axis positioning, you'd need to invest a lot of effort in getting the extrusion exact too. | |
| Jul 5, 2020 at 23:44 | comment | added | Faraz Ahmed | Yes printers at my price range don't really provide what I'm looking for, that's why I'm saving that labour cost and putting it into quality parts. | |
| Jul 5, 2020 at 23:39 | comment | added | R.. GitHub STOP HELPING ICE | Can you clarify what "super-precise" means? Are you building this printer to get precision you can't get at an affordable price in commercially available printers, or because you just want to do it yourself? | |
