Hard to beat for the money.
It printed fine right out of the box as good as my other 9 printers. I exclusively print PETG for usable parts. Some "hairs" are normal with this printing.
I went online and found an amazing simple upgrade that you can print and then just buy an all metal hot end. It has a dual close blower fan right up on the print nozzle. So when the filament is extruded it is instantly fused. So the prints come out, not only dimensionally perfect but very smooth with no PETG "hairs" at all. Now I want to have dual fans on all my printers because of this enlightenment.
The design of this printer with the four 8 mm rods and circular bearings seem to make it very precise, as a sort of copy of the Prusa printers, it really impresses me.
I have 10 printers and this one with this thingivese upgrade hot end prints better than all of them. Smooth with very precise layers, It is dimensionally right on.
The only issue I have had is the screen "button" to move the X axis is weird, but I think that is in the firmware. It is not enough of a problem to even upgrade the firmware. Press this X move button and nothing happens, then press the Y 10 mm move and the X moves 10 MM. Has to be in the programming. (I program PLC in C++ as part of my work.)
The bed is not flat from the factory. And doing the leveling was nearly impossible. So, as an engineer, I put aluminum foil under the low spots and now it is perfect. I don't hear much of this from other owners, so it may just be this bed. I also took off the glass clamps which I think are too tight and replace them with small black spring clips.
It is, right now with the upgraded hot end, my favorite printer. But straight from the factory it is OK and works fine. I just saw this upgrade and knew I had to print it out and put it on my Mega S.
This printer is used constantly, now. So pardon the dust. I have ten printers most are in constant use and clean them as needed.
These are PETG at 248 deg hot end and 85 deg bed. Notice the aluminum foil under the front end to get the bed flat. I don't know if it is the 8mm rods are bent or the bed is just not flat? But it works great with shims.
Notice there is NO stringing with this printer. And .16 layer height and .36 layer width, 100% infill because these are functioning parts and need to be as strong as possible.
Most people would love these upgrades. All metal V6 hot end and new printer head you can print on this printer.
