Upgrading to Linear Rails a Waste of Money? - An Evidence Based Answer

  Hey! Thank you for taking the time to watch this video. I just wanted to quickly point out a mistake I made in the video! When I show the grease I use, I present a grease that I claim does not have PTFE in it. Funny enough, as I find the link for it to put in the description, I discover that the Syncolon it has in it, is indeed PTFE. So, you may not want to use this specific grease... Sorry!

  Another great video! <br>I agree with your sentiment on linear rails for quality and speed, with a huge BUT:<br>As you pointed out, V slot wheels can and do cause problems when theyre not adjusted perfectly; this inevitably leads to a problem that you have to diagnose. I think it&apos;s extremely important to reduce the number of things that can go wrong, especially if you have a cheap printer.

  Linear rods are the best because they look cool. Shiny, shiny!

  Alex Kenis has a pair of videos about how to clean and improve low quality linear rails. &nbsp;Regarding speed and steps, your rails were probably binding a bit from not being quite aligned.

  I&apos;ve just printed a new fan duct, stripped the printer then realised I need this and that :face-fuchsia-wide-eyes:

  I&apos;ve been waiting for a video like this for ages, thanks for your time and dedication 🥳🙌🏼

  I&apos;m tired of dealing with pom wheels wearing down so I replaced the X and Y with linear rail kits. &nbsp;That&apos;s the end of that.

  Just like I said in previous videos. This channel blows my mind if we speak of 3D printing brainiac

  I think linear rails are a great solution to the wrong problem here. <br>I used linear rails in automation for ages. But for such light loads I keep using V-slot rollers on my printers.<br>Rollers run dry, can operate well in a dusty environment like a workshop. And they are as much maintenance-free as linear rails if set up correctly. <br>The problem with rollers is usually the human factor. People don&apos;t know when and how to set them up properly. And they will become loose or grind flat spots eventually.<br>The same people will ignore their rails and carriages too, letting them getting clogged from dust filled grease sludge or running them dry causing excessive wear.<br>My first printer is around 8 years old, has a lot of print time and still runs on the original set of rollers. The rollers wore down the black oxide layer from the running surface of the aluminium extrusion over the years and have their contact surfaces reshaped by the V-slot but still run nice and smoothly.<br>Rails aren&apos;t that expensive anymore, but they aren&apos;t really better in a light load scenario. They will fail too, just in different ways than rollers do. They can offer a more compact carriage solution but make the gantry heavy in a coreXY constellation.

  I wrote this on another post promoting this &apos; upgrade &apos;. &nbsp;&quot; The models of vibration presented in all the videos of the 3D printers which use a moving bed is flawed. The problem is not the present bearings on the 3d printers as such, but the stupid top plate. The carrier plate can be made to act quite rigidly with the use of the standard or modified bearings , but the top plate is not a rigid body compared to the carrier due to the use of those stupid loose locating bolts and springs. The top plate moves out of sync with relation to the printing head on acceleration and deceleration due to the effects of the moments of inertia. This is why the first method to reduce the effects of ringing has always been suggested as a reduction in printing speed and acceleration. These printers are just not rigid enough to work under such high acceleration and deceleration values. With the latest printers the thirst for high printing speed as a selling point is only exacerbating the problems. The solution is simple and that is to reduce mass drastically while increasing rigidity. Simple but not easy nor cheap. Just treat these machines as they are, pure hobby printers and enjoy the toys they make.

  Awesome video again! Loving the in depth content- as someone who spends a lot of time upgrading printers it’s useful to have it in well made videos! Keep it going
