I possess both models. The D series operates on a 12v system, featuring an external power supply and an 8-bit CNC board. On the other hand, the E series runs on 24v, equipped with a Meanwell power supply affixed to the frame. The E series offers flexibility with either an 8-bit or 32-bit configuration. Additionally, both printers may include a magnetic base.
However, I've noted a concern: the website technician should dedicate more attention to clearly defining the specifics in the refurbished Pulse printer listings. Offering this insight, it's essential for potential buyers to have accurate and detailed information for an informed decision.
