Electronic sound on steppers on slow move

[komatias]

.... I suspect due to your machines construction, it is acting like a sound box amplifying whatever the stepper noise is

That stands after watching your video. It is working like an acoustic guitar if you will. You motors do not sound too bad otherwise. The squeaking though? Lubrication needed on the rails?

Yes, i've got put some WD40 in there with a bit of grease :) The machine cuts quite well, I've made a temporary dust shoe out of ply wood that looks awesome. I've got a few problems but I will discuss this in another thread :) Just received my inductive home switches and my 3D printer will be delivered today so I can make their holders. I've got a lot of things to improve on the machine :)

That's right, the main gantry is constructed with a torsion box, so it's like an acoustic box as you say :)
