Hello everyone, i made a MPCNC with working dimensions of 600x1200x50mm with mid-span supports on y axis. I have a makita 3710 wich has 30000 rpm and i use single flute bit to cut laminated wood. I have 4mm depth per pass at a feedrate of 2100mm per minute.
The problem that i encountered is when i cut curved lines the bit moves while cutting left and right about 1-2 mm and i get some waves on the part. I didn’t attach anything on the z axis like cables, i attached everything on the xyz parts. I have a slight backlash on z axis but is up and down, not sideways to generate the waves on the finished part. i will post some more pictures tonight.
