Hi everyone I would like to know your comments on using guide wheels (v-groove rollers) for the linear motion system, these guide wheels would be made of acetal with bronze bearing, like these 'economy series guide wheel' from sdp-si (see picture), they are really inexpensive. Are they suitable to be used for a cnc router (e.g. 3'x4')? I will appreciate your commets!   |

| I would guess they are far too weak. Plastics have flexibility, and this is the most important place on a CNC that you want to minimize play. Cheers! pr |
