※ New features
1. Nozzle switching mechanism
- From magnetic tilting (Existing)

- To nozzle lifting (New)
1) Improved mechanical parts durability for nozzle switching
2) Light weight & durable metal structure
3) Bowden type extruders (L, R 2 sets) are supplied as a standard,
and holder for the direct type extruder can be ordered as an option
※ The print quality is inversely proportional to the weight of the print head and gantry. (The heavier printhead or gantry, the lower the print quality.)
When the OPUS200 3D printer was developed, the physical properties of the PVA filament were not easy to print, so the Bowden-Direct hybrid extruder was designed and used for the first time, and it is designed to be able to change the extruder type easily.
However, as the physical properties of the current PVA filament have been improved, PVA is working well even without a direct extruder, (Please consider Panther origami, Venom head printing video. TPU also prints well) it is recommended to use the Bowden type as much as possible to keep better printing quality, and purchase a holder for direct extruder installation separately only when you need to print low-hardness flexible filament or PVA printability is not enough. (The above picture is with Orbiter extruder V2.0. If you want to use Orbiter extruder, you need to change the extruder steps/mm value to match the driver you are using.)
2. 3.81mm pluggable terminal block
1) Easy print-head installation

2) Easy & low cost maintenance
- Enough current capacity for safety ( < 8A )
- Easy wiring for short wires without the connectors
- Wide wire thickness compatibility
- Each parts can be changed independently


※ Color of the wires on Z-axis sensor and servo motor can vary as the manufacturer.
Top 14 Elden Ring Runes Methods That Involve Minimal Combat
Elden Ring’s sprawling world offers countless opportunities to gather runes, but not every player wants to dive headfirst into constant battles. Whether you’re new to the game or simply prefer a more cautious approach, there are several effective ways to accumulate runes while avoiding intense combat scenarios. These minimal combat rune farming methods can help you steadily build up resources without risking your progress too much.
If you’re looking to buy Elden Ring runes or upgrade your gear efficiently, combining these methods with the right Elden Ring Items can further speed up your progress. Here are the top 14 rune farming techniques that require little fighting but yield reliable results.
1. Chest Farming in Safe Areas
Certain chests in the game world respawn after resting at a site of grace. Find spots with chests containing runes and repeatedly collect from them to gather steady rune income.
2. Selling Unwanted Elden Ring Items
Accumulating items you don’t need and selling them to merchants can earn you a good amount of runes without combat.
3. Trading in Multiplayer
Participate in co-op or PvP sessions where you can earn rewards or trade for runes without heavy fighting on your part.
4. Spirit Ash Farming
Use your Spirit Ashes to take the brunt of fights while you hang back and avoid direct combat, collecting runes passively as your summons do the work.
5. Rune Pick-Up from Boss Remnants
After defeating bosses, some remnants or rewards can be farmed without direct combat by exploiting respawn mechanics, allowing you to gather large chunks of runes.
6. Exploring Hidden Caves and Catacombs
These areas often contain rune-filled items or traps that grant runes without the need for many fights.
7. Mining Runes from Mining Nodes
Certain mining spots yield materials and occasionally runes without enemy interference.
8. Leveraging the Gold Scarab
This talisman boosts rune acquisition from all sources, making even minimal combat and collection more rewarding.
9. Passive Farming with Bleed or Poison Builds
Set up your character to apply status effects and then retreat, allowing enemies to take damage over time without requiring continuous engagement.
10. Using Rune Boosting Consumables
Some consumables temporarily increase rune gain, letting you maximize returns on minimal encounters.
11. Trading Items for Runes at Merchants
Certain rare Elden Ring Items can be exchanged for a high number of runes, letting you avoid combat altogether.
12. Engaging in Site of Grace Rest Loops
By resting at sites of grace near rune-rich respawning enemies or chests, you can create safe loops to gather runes with minimal risk.
13. Purchasing Runes from NPCs
In some cases, NPCs offer services where you can buy Elden Ring runes indirectly by exchanging rare items.
14. Utilizing Spirit Summons as Distractions
Call forth spirit allies to tank damage and deal damage while you safely collect runes or loot.
These minimal combat methods offer a great way to build up runes steadily, especially for players who want to focus on exploration, questing, or improving their gear without constant fighting. Combining these approaches with rune-enhancing Elden Ring Items and strategic gameplay will accelerate your progression.
