In you CNC profile cutting thread, by requsting others to Cut 4 motor mounts in one go, you have left the option open for guys to have a second motor for the Y car. My question is when you weigh the costs and the benifits of the second motor where do you stand. If it gives us better results why don't we think of incorporating the second motor at the start itself. |

Quite frankly, the MechMate Y-car doesn't need a second motor.
The ShopBots use to have a flimsy y-car with a strange "holddown" system. The cure offered by ShopBot was to install a second y-motor. Quite a few people put 2 y-motors on their ShopBots. ShopBot have since improved their y-car and I havn't heard of people using 2 y-motors for their new cars.
Putting a second y-motor onto a MechMate is straightforward mechanically, but it is just one motor too many for a basic controller. You will need another driver and there will be some experimentation to get 5 drivers working off one parallel port.
The advice to cut 4 motor mounts is based on the cost being only about $5 each. |
