FAQ
Can I use this with my own hardware?
The full source code (software, firmware, CAD files) is provided after purchasing the hardware kit. Email your order confirmation to service@nenpower.com and we will send you access. You will need to calibrate mechanical parameters if using custom hardware.
What's the actual precision I can expect?
Typical precision is ±0.1mm with proper calibration, thanks to 16-microstep drivers and 4.5:1 gear ratio. Repeatability is excellent (~0.05mm). Absolute accuracy depends on calibration quality and mechanical tolerances.
Do I need robotics experience?
Basic programming knowledge helps, but not required. Our documentation includes step-by-step tutorials from beginner to advanced. If you can install Python and follow instructions, you can get this running.
Can I train my own object detection model?
Yes! We provide labelImg tool for data annotation and complete instructions for YOLOv8 training. The Complete Solution kit includes one custom model training service from our team.
What OS is supported?
Primary support is Windows 10/11 (tested). Linux compatibility is good (Ubuntu 20.04+). macOS should work but is untested. All Python dependencies are cross-platform.
How fast can it pick objects?
Complete pick-and-place cycle: 3-5 seconds depending on distance. Max speed is 100mm/s but actual throughput depends on object spacing, conveyor speed, and vision processing time (~100ms for YOLOv8).
Can I modify the mechanical design?
Yes! CAD files (STEP format) are provided with your purchase. Common modifications: arm length changes, custom end effectors, or adding a 4th axis (rail). The kinematics solver parameters are configurable in firmware.
What's the warranty and return policy?
Hardware comes with a 12-month limited warranty covering manufacturing defects. You may return an item within 7 days of delivery; return shipping is paid by the buyer and the item must be unused and in its original packaging — see the Returns section below for the full terms. We also offer lifetime software support by email.
Warranty
12-month limited warranty covering manufacturing defects. Consumables (suction cups, belts) and damage from modification are excluded.
Returns
Returns. You may return an item within 7 days of delivery for a refund.
- The item must be unused, complete, and in its original packaging.
- Return shipping is paid by the buyer. Original outbound shipping is non-refundable.
- Contact service@nenpower.com before shipping anything back; returns sent without prior notice cannot be processed.
- Refunds are issued to the original payment method within 5 business days of the returned item arriving and passing inspection.
- Items damaged in transit or dead on arrival are covered by warranty, not by this policy — we cover the shipping in those cases.
EU, EEA and UK consumers also have a statutory right to withdraw within 14 days of delivery without giving a reason — see our Terms of Sale. Your statutory rights are not affected.
