Good evening everybody, this is my first post within this forum :wave: :banana:
I recently purchased a 1212CNC from China, delivered to Perth, Australia. I am making a video of my entire experience however I would like to first address some problems first. Please view the attached video which showcases the terrible, gantry shaking chatter along the Y axis, primarily in the Y+ direction, on a cut with a 6mm endmill (see photo for speeds, feeds etc.) and I can't seem to overcome it. I also stripped the 4 screws which connect the Z axis to the gantry whilst zeroing the DRO's and will be getting a 4140 steel replacement made on a 5 axis DMG Mori at my friends workshop. Along with the material upgrade from cast 6061 aluminium to 4140, I will also be making the M6 holes into M8's with 35mm of thread engagement. I believe that this will reduce the chatter however I still want to know what the community reckons.
Cheers from down under!
Regards,
Aaron
