Running a Vertical Surface Test can help you spot these problems. Another useful test is the Z Wobble Test, which checks for cyclical wobble in the Z-axis. If you notice wobbling, recheck the rigidity of your frame and tighten any loose screws.

Tip: Always tighten screws evenly. Uneven tension can cause slight shifts in alignment, which might not be obvious at first but will affect print quality.

Resolving wiring and connectivity problems

Wiring issues can be tricky but are usually easy to fix once identified. Start by reviewing your connections against the wiring guide for your Voron model. Common problems include incorrectly crimped connectors or loose wires. For example, one builder found that their X and Y endstops weren’t working due to incorrect crimping on the MCU side. Fixing the shared GND and VCC connections resolved the issue.

When working with endstop cables, pay attention to the connectors. The XY endstop cable typically has a 4-pin JST-XH connector on one end and two 3-pin JST-XH connectors labeled for X Stop and Y Stop on the other. Double-check these connections to avoid errors.

Pro Tip: Use a multimeter to test continuity. This ensures all wires are properly connected and functioning as expected.

Addressing print quality issues (e.g., warping, stringing)

Print quality issues like warping and stringing can be frustrating, but they’re fixable. Warping often happens when the print cools unevenly. To combat this, use a heated bed and consider adding an enclosure to maintain a stable temperature. For stringing, adjusting retraction settings can make a big difference. Start by tweaking the retraction distance and speed. Lowering the extruder temperature by 5-10 degrees can also help reduce oozing.

Here are some additional tips to minimize stringing:

• Increase travel speed to reduce the time the nozzle spends moving over open spaces.
• Enable features like Combing Mode in your slicer software to avoid crossing open spaces.
• Use the "Avoid crossing outline for travel movement" option to further reduce stringing.

Note: Small adjustments can have a big impact. Test each change with a simple print to see what works best for your setup.

By addressing these common issues, you’ll ensure your Voron printer runs smoothly and produces high-quality prints. Troubleshooting might take some time, but it’s a valuable learning experience that will make you a more confident builder.
