Tronxy (T-nut 20mm) heatbed grinder

thingiverse

My heatbed 400x400mm was very uneven (nearly one mm), so I decided to try a change. First try was that I reset my heatbed and z-axis, then I use a spirit level to level the heatbead. But sadly the cast resin try fails. I dont like to use pertinax (hardpaper) because of the poot heat conduction. And I anyway don´t want to print directly on this surface. Now I use 2mm graphite foil with 3M transfer sheet. Actually I´m grinding the surface and the warm up is excellent. I´ve used the existing V-wheels of my tronxy and buy eccentric nuts. For savety I´ve constructed one to print out. I hope this was usefull .. Joe Grinder based on Surface Grinder by toolson January 31, 2017 Reconstructed for Tronxy X5SA
