My Take on Cheap Kits (Geeetech Prusa I3 X)

[Johnlarry]

We all read that chinese printer kits are a pain in the ass, but I consider myself a maker and a tinker so I said, screw it!. The kit arrived I assembled it, and off course started having problems. I´m going to list all the problems and solutions that I faced and came up with, as a warning, for anyone considering buying a chinese kit, and specially from Geeetech. ovo.fyi/lorem-ipsumovo.fyi/emp-mailovo.fyi/10-minute-mail


Poor instructions, a pdf that didn´t match and really poor explained videos. This added to my newbieness made me overtight one of the screws breaking the acrylic, uncorrectly tight the belts, leaving them too loose. (took 3 days to assemble it, and had to come back over my steps several times)

Both smooth and threaded rods bent. (First I attempted to strighten them but ended up replacing all of them in the end)

Underpowered PSU, got a 15A instead of at least 20A, 25 would be the recomended here (ended up burning and had to replace it, went with a 30A psu).

ACME nuts inf the Z axis, when the rods are simple threaded. This caused a LOT of Z wobble. (Drilled a bigger hole on the top threaded rod mount and replaced the ACME nuts with an anti wobble print from thingiverse)

THE WORST CABLE MANGEMENT EVER!. From the instructions really bad cable managmente and those cable wraps are plain useless (rewired the cables from the extruder and bed, added a lot of zipties, added that orange corrugated guide, a string for the bed wiring to avoid it blocking the endstop some times, and a print from thingiverse for covering the electronics and a bunch of cables)

Maybe you didn’t read the instructions carefully, it’s explained in great detail.
1. Maybe you need to use a suitable tool to install the belt;
2. The power supply is a standard power supply;
3. The power lines on the extruder are one-to-one correspondence;
4. The z-axis fixing with the lock nut is fixed without punching;
Fortunately, your problem has been solved.

1.I'm sorry to cause you some trouble. The printer may be damaged in transit. We will provide replacement.
2. If the power supply burns out, you have to confirm that the power supply gear is in the correct gear positionAnd you can measure if the output voltage of the power supply is in the correct range
3.a lot of Z wobble should be that the z-axis motor is not fixed.
