The QIDI Tech X-one 2 is a pretty traditional fused deposition modeling (FDM) printer that prints in XYZ coordinates. The print head moves in the XY directions, and the print bed moves in the Z direction. The bed is heated, and the print head includes a cooling fan. The build volume is a cube 140 mm on a side.
Now, for all the issues I can think of:
* The documentation is sparse, and poorly translated into English. The PDF on the included thumb drive is more complete than the printed manual, so make sure to refer to that.
* When you want to change filaments, you're supposed to be able to heat the current filament and run the feeder in reverse to back it out. For my printer at least, this doesn't work. The sorta-warm filament just below the feed gears develops a bulge, which jams it so that it will feed neither backward nor forward. Twice now, I've had to disassemble the print head and cut the filament to get it out. I'm hoping that just heating it, holding down the manual lever that disengages the feeder, and pulling it free will work better.
* It seems to be possible for the printer to retain a bad state or incorrect awareness of position when it is shut down. Two or three times, at the beginning of the first print attempt after turning it on, it has started by trying to drive the print bed down through the floor of the printer. I'm not sure exactly what causes this, but I haven't seen it since I started 1) making sure to always push the button on the "print complete" dialogue box before turning off the printer and 2) never removing the SD card while the printer was on.
* I've gotten the "sensor error or power is not enough!" error a couple of times. It seems to mean that the connector to the heated print bed is loose. I re-seat or wiggle it and the printer is good to go on the next try.
* The printer sings most of the time, but if I turn up the travel speed too much, it sounds ... bad. A little grindy. I don't know if this is evidence of a real issue or not.
Until the next cycle,
