Review on Iverntech MGN12 700Mm Linear Rail Guide With MGN12H Stainless Steel Carriage Block For 3D Printer And CNC Parts by Brad Davis

These rails are a simply excellent. The Zyltech train wrecks that would not even slide without force were sent back after a week of them promising replacements they never bothered to send. These things were usable right out of the box. They slide very easily by tilting the rail and have no lateral movement at all. They arrived at my door 18 hours after I clicked buy now, individually boxed, carriages mounted and ready to use. They mounted easily (I cut two 700's down to 520 with a dremel) and are working great. I also bought an LDO MGN12H x 400mm from Filastruder. Thinking was the X axis gets a lot of work and I wanted a known, good brand on that axis. These roll better. When I started turning up the print speed.I noticed I was getting ripples in the X axis. Further investigation found the machining on the rail had tiny ripples in the track.which showed up on prints when the speed increased. I ordered a replacement from here.voila. When I need more linear rails, and I will.I’ll be back.
