    I finally got my C-Beam machine up and running. After a short while during alignment/testing, I noticed a weird noise coming from my Y axis. The X and Z axis are smooth and "quite". The noise sounds like kind of like a squeak or binding maybe, hard to describe. So far, I have checked to make sure the base runs smooth on the rails. The lead screw is not to tight between the ends. The flexible coupler has space to move, and I have oiled the lead screw.

    Could it be the anti-backlash block? I'm not really sure how to adjust it properly. I screwed in the grub screw until it touched the block, then added the nut to hold it in place. There was no backlash in axis so I thought I had it right. Is it possible this has moved and causing the noise?

    Thanks!

    Squedking noise? Lubricate your leadscrews with NB Dry/ptfe lubricant. Do not use oil

    I also am experiencing some sqeaking/groaning kind of noise when the gantry is moving. I think it's coming from the X axis, but it could also be the Y. So I can just put some ptfe on the lead screw itself, or in the block that it screws through? I have some Boshield T8 here which is a dry lubricant, but it does not have ptfe, I think it's paraffin. Is there a brand you recommend?

    You do not want to use paraffin. I use Blaster Dry lube with teflon and it has worked well for me over the years.
