Well, its taken me about 18 months, but I have finally completed my first router.
Its based around a fixed gantry supporting the Z axis, with Y axis on the X axis.
Controller is a Parker Compumotor 6K4, driving Parker OEM 770 servo drives. The Z axis uses a Compumotor SM232 servo coupled to a 10 tpi linear actuator, The Y axis uses a Compumotor SM232 servo coupled to a THK KR33 1tpcm actuator, and the X axis uses a Compumotor SE231 and 10:1 gearbox driving a THK KR45 0.5tpcm actuator.
Other details: Everything is fixed to a piece of 18mm plywood, the Y axis is fixed to 38mm worksurface, the Z axis gantry is in 70mm tanilised timber, reinforced with plywood. (The Mk II is intended to be more solid, but this set up is suprisingly rigid).
The work surface is a piece of Bosch Rexroth Aluminium plate with 4 T slots, to which I have fixed some lengths of 30mm timber that I am using as a sacrificail work surface.
I am using a standard Bosch router that clamps into a nice rigid aluminium housing. I need to tidy up the wiring as its a bit of a mess, and improve the dust extraction...
Pic 2 shows the facing of the sacrificial work surface (the tool touches down on the microswitch to set the table height/tool height) to the height of the microswitch.
Finally, I have plans to adapt the router to a depositier for 3D printing...
Thanks for reading!
