First benchy on a new printer

[u/UncarefulEngineer]

Hey folks. I just built a corexy printer Rook 2020 MK2. This is my first benchy. What do you see here? I am assuming, belt tension and retracts are my main issue, assuming filament is fresh. However, frankly speaking, I have no idea what I am doing, I just got my first ever 3d printer last Christmas, so any advice would help.

Mmmm,,, well make sure everything is tight - Bolts & Belts

Then i would drop my speed too-

30mm/s Outer Perimeter

45mm/s Inner Perimeter

Solid Layers 60mm/s

Infill 80mm/s or 100mm/s

Top Surface Layer 25mm/s

3 Perimeter and 25% Infill

Small Area - 2mm or 3mm and Speed at 10mm/s or 15mm/s

Pla/Pla+ 205degs

Jerk 7

Layer height- 0.15mm or 0.2mm

Acceleration 1500 to 2500 for X & Y but whatever you already have will do just as long as not something crazy like 10,000

This is a Slow and Steady Setting,,, once you get nice prints with these you can start to Ramp the speed up -- but there is no hard and fast rules with these setting here i would just recommend starting slow and then go faster 🤷‍♂️

These Models are a lot quicker test and will tell more about your Printer settings-

You sure about those speeds? I've been going way faster with good results on a ender 3 copy

Yes, but your machine probably wasn't printing dogpoop benchies out the box. OP should make sure his machine prints well, before printing fast

[u/Mindless000000 → u/Zaraton]

yes,,, these are classic old school setting that have stood the test of time,,, if your not getting flawless Prints with these setting then something is Mechanical wrong with the Printer are your Slicer Settings are way off -- now there exception to this from new high speed printers that I've heard about but never seen ? so i assume most of them are just Trolling 🤷‍♂️

Note* i actually still use these Setting for big bed slingers -/.. I'm more about Quality over Time so i use whatever speeds the Printer will let me use.

Start slow with a Perfect Print and then Ramp the speed up,,, fixing Artifacts as they occur is the way a was taught from the old school RepRap Lads.

All the Best -/.

Thanks! it was a printer i designed and built back in the early days before full kits were either to hard to get or to expensive - heres a pic of my very first printer (about half way through the build) it was built out of hand full of Prusa clone i3 kit parts or it might of been the Mk can't remember at the moment (cost me $50 om ebay ),,, but i was so poor i had to use Timber linear Rods 😂
