Paint on Galvanize leads to adhesion problems, Best to either strip it off completly with a sandblaster and start over, or use an automotive grade etch primer. |

Ryan (creator of the MPCNC) used car wax. https://forum.v1engineering.com/t/new-mpcnc-for-2020-primo/16891/1060 --- Quote from: Ryan --- I put some old car wax I had laying around on it (with steel wool to get a shiny finish). That seems to have kept rust away so far. The parts I did not wax have tiny speck of surface rust. --- End quote --- Related thread: https://forum.v1engineering.com/t/tube-prepping/21103 --- Quote from: K Cummins ---A little carnuba-based paste wax just to give it a moisture barrier. Any paint you give it will get worn off almost immediately. The point loads between the bearings and the rails are immense. In fact, I’m sure it’ll wear off/squeeze out any wax you put on as well, but there’s no getting around that. You want to protect the other 99% of the rail. --- End quote --- --- Quote from: Jeffeb3 ---silica free paste wax. The silica will mess up your woodworking projects. --- End quote --- There are also some recommendations for "spray garage door lithium grease" and "white lithium grease (spray on)". Scott |
| Howard_Casto:
Lithium would probably be the best choice then.... it's the "cleanest" of the greases and wd40 sells it in a spray can so if it gets clogged with sawdust it'd be easy to wipe off and re-apply. |

this is just odd to me. I'm using a piece of conduit i had in my basement for over a yr and it has no rust on it. I will say the surface was rougher than the other pieces but i just took a sheet of sand paper to it to smooth it a little. when it's done and I get it in the basement i'll see what I have. honestly straight wd-40 and steel wool has been my favorite rust removal/anti-rust coating for decades. I have everything i need. depending on kids i should be able to get the steppers wired up in series this weekend. |
| nitrogen_widget:
I thought i had everything i needed. I did not have enough wire for the steppers. Ordered pre-made wires from V1 so i didn't have to cut and slice too much. will be here tues or wed. but, it moved on both axis just fine. :) |
