Guide on Ender 3(V2/Pro) Bed Spring Upgrade

Upgrading the bed spring of your Ender 3(V2/Pro) 3D printer should be a top priority on your wish list if you’re looking for improved printing results. In most cases, an upgraded bed spring will increase the stability and accuracy of large prints.

It also helps with re-levelling since it is much more efficient at evenly pressurizing the surface compared to its stock counterpart. With an aftermarket solution, you can squeeze more consistency out of your device and limit any print warping caused by thermal shifts under the bed during long prints.

With just few extra dollars invested in this upgrade, you can completely change the way your Ender 3 behaves during print jobs!

How long are Ender 3(V2/Pro) bed springs?

The springs inside of the Ender 3 bed are a vital aspect that directly impacts the print quality. They are an often-overlooked factor, but they come in different variations that carry advantages over each other.

The standard length of these springs is 40mm, which is optimally suited for most 3D printing materials. Shorter springs – around 30mm – can provide a slightly better adhesion while longer springs (up to 50mm) offer better stability and thus should be used when printing models with large flat surfaces.

Regardless of the spring type, one should never forget to check on their tightness and proper extension from time to time.

Why are Ender 3(V2/Pro) bed springs are important?

  • They support the printing bed and allow it to move up and down smoothly, helping to ensure that the print head can make precise movements.
  • Bed springs also help protect parts from physical damage during transportation, as they reduce vibrations that would otherwise be transferred to the device.
  • They also absorb some of the noise generated during printing which helps reduce overall noise levels in a near vicinity.

When kept in good condition, bed springs are capable of providing reliable performance for many printing cycles; making them a worthwhile investment for those who are serious about creating quality pieces using their Ender 3 printer.

When to replace Ender 3(V2/Pro) bed springs?

Replacing the bed springs on an Ender 3 3D printer should be part of your regular maintenance schedule. If you notice that your prints are not as precise or have inconsistent layer thickness, it may be time to replace the bed springs.

Another sign that a spring replacement is needed is if the bed does not level properly. Replacing these components are relatively easy and can make a huge difference in the precision of your prints.

To be proactive, you should inspect springs and other mechanical components of your 3D printer every few months to ensure they are in good working order.

Ender 3 (V2/Pro) Bed Spring Replacement Steps

Replacing the bed spring on your Ender 3 3D Printer doesn’t have to be a daunting task – it can actually enhance your printer’s performance.

All you need is a

  • Replacement bed spring,
  • Anti-seize lubricant, and
  • An allen wrench of the right size.

Step 1: First remove the build plate from the printer’s platform by loosening the set screws with a hex wrench.

Step 2: Disconnect all the wires connected to it, including those for the thermistor and z-endstop.

Step 3: Once removed, carefully take out two of the four existing springs, being sure not to instinctively blurp them in frustration.

Step 4: Now insert two new springs at their respective positions, making sure they are oriented with ex-changeable ends on opposite sides of the bed bracket and install them as parallel as possible while avoiding cross-connection helix structures.

Step 5: Reconnect all wiring that was previously attached and slide back your newly installed bed into its original position. Tighten all screws finger tight and you’re done!
