Nice work!

[@UtubeUsername123545]

excellent work man ... thanks!

[@tw2ka644]

Great to hear, you're welcome!

[@toddmiller869]

excellent. I have been watching tons of videos to get ideas for my own build and this is what would be good for me.

[@tw2ka644]

Great to hear! I have a video coming on the finished mill soon where I've gathered some thoughts and details about the project. I hope it also helps.

Very inspiring work. I'm thinking of building it myself but I'm interested in the level of accuracy you achieved? Thank you for sharing all the specs.

[@tw2ka644]

Thank you! Theoretically you can hit sub 0.01 mm accuracy with the machine but in the real world the tolerance zone is propably 0.05 mm. During testing I have measured a aluminium plate with holes cut in to it and the locations of these holes were off by 0.02 mm.

​@@tw2ka644 Impressive! Thanks for your reply

Really nice machine! Have you considered filling the column with material to increase mass and reduce vibration?

[@tw2ka644]

Thank you! Yes indeed I have. I considered filling the base tubes as well as the Z-axis tube with sand at some point.
