I have purchased TRONXY P802MA and have it running for the past two months. Working pretty good. Have been doing the basic mods. Printed power supply case with plug and switch, electronic case for control board and two mosfets, added the two mosfets "extruder, and bed". Those mods are working fine. Now for the the heatbed. Did the prints for various parts to steady it better, and clamps for theby olesailor - Prusa i3 and variants
