Cube 3d printer for 2020 Al profile

thingiverse

I slowly finishing my printer so i decided to introduc it for everyone whose looking for inspiration. My printer is original Flsun cube witch have frame from 2020 aluminium profile (but this build can by use for other 2020 frame based printer like tronxy X5S). I liked it, but its problem was that it has 310x310 mm hotbed size but original can't reach the edges and can use only 260x260 mm of hotbed. This I solved with rebuilding on corexy system, which I separately post it here: https://www.thingiverse.com/thing:3263329 Second problem is that the Z asix is out of cube and thats why it can't be enclose. This can be sovled easy, you need only add two 2020 profile (460mm long) and with saw shorten Y rods, Z rods, Z Trapezoidal rods and the "L" profile on hotbed holder. I was worry about temperature of stepper motors so i create design to keep them partial out from insade chamber. I just meassure the temperation - inside of chamber is 55°C and the XY ande E motors have about 52°C. Z motors is totaly cold. The side windows (from plexiglass - polystyrol) can be easy remove with only two screw - thats for easy maintenance access and good vissibility. The cover of the printer is from lacquered polywood and from inside is glued 10mm insulation foam. Most teat losses is throught plexiglass part but, I don't count with temperature over 60°C just due to low temperature plexiglass resistance (next mayby I'll use polycarbonate) Electronic inside is Duet 2 Wifi which is on holder with mosfets and together cooled with 120 mm fan. Edit: 2019-04-08 add holder for PanelDue 4.3" with light switch and termometer for chamber temperature
