Hello,
I’ve been using my Flashforge Dreamer biweekly for about 6 months now. The other day, I took a print off (this print was perfect, no problems), and turned the printer off. About an hour later, I turned the printer on, and attempted to start another print, but the printer began to make a loud, ugly grinding noise, and as the printer began to set up the bed, it became clear that al of the axes measurements are off. I tried resetting some things and printing different prints, but each time got the same problem. Is this a problem with the motors, the limit switches, or maybe something else? And how can I fix it?

I have to ask, and don’t take this as sarcastic or witty, if the printer stopped working after it was off for a period of time have you tried just resseting the power? It sounds like for some reason your endstops are not registering?
Check that all of the limit switches are engaging when the bed and print head gets to its home position, mine get bent every now and then, I just gently bend them back in to position. There is a green led on the limit switches that lights up when the switch is pressed.
Most likely cause is a broken wire in either the X-axis limit switch cable or the X-Axis motor cable.
Both are easy to repair if you get a replacement cable from Flashforge.
If the limit switch wire is broken then homing the printer will cause the carriage to move smoothly to the home position and then start banging into the limit switch.
If the motor wire is broken then movement in the x-axis will pause briefly at random intervals or will not move at all. When it pauses it will lose it’s position and any print will develop an offset and the head may end up banging into the limit switch.
Flashforge ship a replacement sensor wire with the printers. The replacement motor cable will need to be obtained from flashforge.
limit switches…
Try to slightly bend the limit switches, let them been contact the nozzle movement part, I used to have same problem, but solved out.
And, try to ask the custom service, they are nice.
When I got a problem on the nozzle, they sent an another extra new one for free.
Cheers
Check to make sure ur wires are interfering with homing the machine.
Are the belts loose and is the gantry square with the frame? I’ve had belts loosen off and skip teeth on the stepper gear and therefore been dramatically out during the print.
I have a similar problem. When I move in the Y-axis (y), there are about in the middle of the travel-distance a slight cracking noise.
Thereafter this point, the print head rattles when I want to drive in the x-axis.
The belts are tensioned and the gears are clean. The Endstops work properly and the green light comes on.
Any idea?

Could be bent smooth rods.
I do not think so. If I move the carriage by hand, I can´t provide a resistance or crack. I have cleaned the rods and freshly oiled. The belt seems to be ok.
