I know it is going to be a pain, but this machine is built and used differently by everyone so we need more details than most. A video is going to be key, nothing fancy at least 30 seconds of cutting preferably with a close up of the cut and then a bigger shot of the machine.
Machine size is important, especially the z height and length. Spindle type. Bit type (pics help) Feedrate Depth of cut Material being cut
