Why should I upgrade to linear rails?

Short answer: Reliability, Repeatability and Precision Reliability: The main advantage of linear rails is reliability. Linear rails do a very good job at constraining motion and limiting deflections. They will take longer in the initial setup to get everything installed, positioned, trammed, and mounted but ounce they are dialed in you can expect 24/7/365 printing with almost zero maintenance. Not to mention bed leveling is a thing of the past, we just run solid spacers and a touch probe on our production machines. Repeatability: With linear rails installed you have essentially eliminated wear out of your 3D printer you can print part after part, batch after batch with no change in part quality. Precision: At MDG we print functional parts with 0.4 mm and 0.6 mm nozzle size so we haven't really tested the precision with ultra-fine nozzles but we suspect there will be improvements in precision as well. The highest precision we tested was 0.1mm layer Benchy with a 0.4 mm nozzle and well it looked flawless.
