I'm planning on building a cnc router mainly for cutting wood and foam. I've already began gathering up some parts and started designing the machine in solidworks.
I have 4 IM483H drives and 3 IM805H drives. The 4 IM483H drives were used and are already mounted to a pcb with a rectifier for DC power. The 3 IM805H drives appear to be new and are each mounted to their own pcb.
I've also got 4 parker os22b stepper motors off ebay. They may be a little small but couldn't pass them up for $50 for all of them.
The rails I'm going to be using are rollon 43 series. I figure they would be more forgiving than profile rails because they don't need as precise of a mounting surface and they were cheap.
I'm considering doing a belt drive for the x and y-axis and buying a screw driven linear actuator from ebay for the z-axis.
Here are the parts I've accumulated so far.
This is the basic design I'm working on.
I'm not sure if I should drive each side of the gantry independently or run it off the same shaft.
The design as shown is 40"x66" and should have a cutting area of around 35"x54". I plan for the gantry to be made out of aluminum and the base will either be aluminum or steel.
As I am new to CNC any advice would be welcome. I don't plan to do anything requiring high tolerances however I still would like to have a pretty solid machine. I'm trying to stay below $1k for the whole table.
