Frequently asked questions
Can it run on 12 V or 24 V?
Yes, the listing says it supports both. The wiring differs between the two, and at 24 V one terminal is left unconnected. Follow the wiring diagram in the listing before powering it.
What size is it, 200 mm or 214 mm?
The listing title mentions 200 × 200 mm, but the product parameters list 214 × 214 mm. Check the bed dimensions against your printer before installing.
