About the Tronxy x5sa 400

Tronxy x5s-400 review

It was a major thing when Tronxy debuted the X5S in 2018 for around 300 dollars. The CoreXY 3D printer kit was affordable for the 400 x 330 x 330 mm build capacity it provided. It has rapidly become a best-seller.

Tronxy introduced a series of improved X5S models. Many of the models addressed issues that original users had with the earlier version.

The Tronxy X5SA 400 is the first enhanced version of the X5S. It has flaws of its predecessor while also adding some features. If one already has the X5S, they can buy an upgrade kit rather than getting a whole new X5SA).

It sells best because of its 330 x 330 x 400 mm print bed and a 350 dollars price tag.

What is the Verdict?

Tronxy x5s-400 review

The Tronxy X5SA 400 is a promising device. It has a larger-than-average construction capacity and semi-automatic bed leveling.

To perform like the Artillery Sidewinder X1 or Creality CR-10 V3, the printer will need a lot of tinkering, maintenance and upgrading.

The Tronxy X5SA 400 is a good beginning point in the hands of a skilled and determined builder. If one invests time and money in the printer, it could become a beneficial addition to their workshop. This journey may be tedious for first-time 3D printing explorers


Assembling Tronxy x5sa 400

Tronxy x5s-400 review

Missing screws and nuts are standard because the X5S is sold as a DIY kit from TronXY. Significant components being left out is an uncommon occurrence, yet it has happened. These components come included with the Tronxy X5S :

  • The Printer
  • Twelve aluminum profiles (2020)
  • One Z Axle ColumnX2 Root
  • One LCD Display Cable
  • 1X Indices
  • One Acrylic Fixed Foot
  • Single Six Angle Tool
  • A Power Supply
  • Single A Main Board
  • One Limit Switch Set
  • One Squeeze Out One’S Head
  • Single  Axle Left Frame
  • One Acrylic Power Box Bottom
  • A Motor Line
  • Nine Polished Rod
  • A Display Panel (Acrylic)
  • An Axle Right Frame
  • One Memory Card (Card Reader)
  • A Cross Screwdriver
  • A Screwdriver
  • One USB Line
  • A Motor (Z Shaft)
  • A Z Upper Panel
  • A  Motor (Y Shaft)
  • Single Screw Pack
  • A Pack of Print Accessories

The assembly instructions in English are not clear. This would frustrate the inexperienced people or first-time builders. 

Where a line must be drawn is when referring to incorrect components, confusing wires, and instructing builders to use parts that aren’t even included with this model. Aside from that, the build time is fairly modest, ranging from 3-5 hours. It depends on ability to follow directions and experience.

Components such as the PSU, hot ends, cable guards, gantry and axis carriages are shipped pre-assembled. This reduces assembly time. The cable chains are also useful for keeping a clean, orderly build, so bonus points there.

Quality control appears to be lacking in the manufacturing process. As seen by variation in the creation of parts, particularly in how they fit together, as well as poorly labelled components, which is unsurprising given the price range.


Print Technology

Tronxy x5s-400 review

The Tronxy X5SA 400 is a DIY kit with a CoreXY 3D printer design, which distinguishes it from the sea of pre-assembled cartesian XY 3D printers. Let’s find out whether that’s for the better or for the worst.

a. Corexy Printer

Generally, CoreXY printers are cubic. The print head is moved by two lengthy timing belts, each driven by a stepper motor. While the print bed is moved up and down the Z-axis by lead screws and guide rods.

CoreXY printers have various advantages over conventional Cartesian (X/Y/Z-coordinate) 3D printer types due to the frame design and how the axes move. For example, because the motors are stationary, there are fewer vibrations and torque, as well as a gradual increase in print speed.

However, its greatest strength is also its greatest flaw. The belts are necessary for CoreXY design to function. They can also pose problems if they are not properly tensioned. Getting this properly during assembly is a critical step that will save users a lot of problems down the road. 

There is no method to tighten the belt. Getting an appropriate tension while building the printer can be challenging (especially for first-time tinkerers). The belts will loosen over time and will need to be tightened again at a later date.

The Tronxy X5SA’s cubic structure is made up of a mix of 2020 and hefty 2040 aluminum extrusions. The printer is quite sturdy when properly assembled (make sure the screws are snug). 

This skeletal printer seems reassuringly robust, even if the stepper motor and extruder brackets are made of plastic.

Given that the gantry is subjected to a substantial amount of vibration when in operation (CoreXY system or not). The belt system can add strain on top of that, some support angles should be included as standard. However, there are 3D printable community designs to refit the printer with.

b. Print Bed Design

The print plate inside the gantry is larger than typical, measuring 330 × 330 mm. The print plate slides up and then down on two lead screws for the Z-Axis. It is guided by guide rods, as is typical of the CoreXY design. With a printed Z-axis height of 400 mm, the printer can handle some massive prints. With a massive print volume (330 x 330 x 400 mm), one can print large.

The print bed is rigid and sticks too tightly to prints, unfortunately. Thus, necessitating the use of blunt force to remove them. The bed is switched halfway through testing and whipped out the painters’ tape. Don’t get too close – the nozzle has the potential to gouge the print bed.

Any bed level user will typically be undone if they hack at the build plate. But, even if one tries to avoid this by removing the bed from the printer entirely – it’s fine. The bed will certainly lose its level, even if one has the fingers of an Operation pro. It means they will have to re-level the bed before practically every print.

Because the two lead screws aren’t connected, make sure they’re at the same height.

On top of that, the Z-axis motors aren’t connected and don’t have an end stop. This is done by the bed-leveling probe, which is mounted to the print head’s left side.

One should make extra sure that the plate is hanging level on both lead screws, as the probe is more error-prone than a physical end stop. This results in the nozzle drilling into the plate. 

To check if the plate suspension is level, get (or 3D print) two identical sized objects. Users can pin it down in between the frame and the suspension to get the same height.

c. Automatic Leveling of Print Bed

Although one would have preferred end stops on the Z-axis (as on the X- and Y-axes), the automatic bed leveling probe is a noteworthy feature on the Tronxy X5SA 400.

At its price point, this technology is a rarity, alleviating part of the pain of repeated bed-leveling, which is required with this printer.

The probe will measure a mesh of 16 locations over the print bed. It will show users to change the six bed-leveling knobs to compensate for the variances in levels.  Although it is technically assisted-automatic bed leveling, this is prefered to manual bed leveling.

d. The Appearances

The Bowden-style extruder is positioned on the backside of the frame. It feeds the filament to the hot end through lengthy PTFE tubing. The hot end and print head wire is routed to the back of the printer using a drag chain. The extruder drag chain, as well as the X and Y-axis belts, are dangerously close.

The cable chain helps to hide the printer’s DIY appearance (even with two cable chains). But the suspension is a bit clumsy, as its weight pushes it down and scrapes against the belt. A situation identical to this can be seen with PTFE tubing.

It’s not quite long enough, and while homing the print head (in the left front corner), the tube is nearly stretched to its maximum length, perhaps interfering with the belt. Upgrades for 3D printing are accessible online and should be explored if one wishes to print with it in the long run.

The PSU for the Tronxy X5SA 400 is located in the back of the printer, with a 3.5-inch color touchscreen in the front.


Slicer Application

Tronxy x5s-400 review

The Tronxy X5SA 400 comes with Tronxy Slicer, a proprietary Cura (15.04.06) skin. It only allows for limited print control, even when expert mode is enabled. Special caution should be exercised when it comes to retraction. 

This is due to the X5SA’s default settings appear to be universal and not tailored to the printer. It is discovered that the Tronxy Slicer underestimates the time it takes to create a print. The Tronxy Slicer has several limitations with regards to modifying print settings.

Alternatively, one can have more control over the prints by switching to a more versatile slicer. For example, Cura, which has an Tronxy X5SA 400 profile.
