The machine can drill its own holes, that you can use to screw in the M5 threaded inserts. They are not compulsory for the functioning of the machine, but they allow you to have various places with M5 tapped, to attach clamps etc to hold the material.
Start by removing the middle v slot rail at the underside of your frame:
Then put a 6mm drill or carving bit on the spindle, and manually put the machine in a home position that has the middle of the drill at this position: 70mm from the left of the wasteboard and 25mm from the bottom of the wasteboard.
And use this: file to drill up to 25 holes in the machine’s own wasteboard – you may have to adapt the file if some holes fall outside the work area of your machine so I recommend that you first do a run wihtout actually drilling into the machine but just to see if it would reach everywhere without touching the machine’s limits (otherwise you may have to remove a column and a row of holes): http://easel.inventables.com/projects/CPQ0lmVfnJFUDbhXPkktNQ
Then, once that’s done, you can screw in the M5 threaded inserts FROM THE UNDERSIDE OF THE MACHINE.
Now but the middle v slot rail at the underside of the fram back in again.
Put a 6mm drill or carving bit on the spindle, and manually put the machine in a home position that has the middle of the drill at this position: 82,5mm from the left of the wasteboard and 25mm from the bottom of the wasteboard.
And use this: file to drill up to 64 holes in the machine’s own wasteboard – you may have to adapt the file if some holes fall outside the work area of your machine so I recommend that you first do a run wihtout actually drilling into the machine but just to see if it would reach everywhere without touching the machine’s limits (otherwise you may have to remove a column and a row of holes): http://easel.inventables.com/projects/VauMg5A15UxyhY18Ept0SA
Then, once that’s done, you can screw in the M5 threaded inserts FROM THE UNDERSIDE OF THE MACHINE.
put a 6mm drill or carving bit on the spindle, and manually put the machine in a home position that has the middle of the drill at this position: 57,5mm from the left of the wasteboard and 24mm from the bottom of the wasteboard.
And use this: file to drill up to 144 holes in the machine’s own wasteboard – you may have to adapt the file if some holes fall outside the work area of your machine so I recommend that you first do a run wihtout actually drilling into the machine but just to see if it would reach everywhere without touching the machine’s limits (otherwise you may have to remove a column and a row of holes): http://easel.inventables.com/projects/JLbY-nXaqj-r1mfRJxUKKA
Then, once that’s done, you can screw in the M5 threaded inserts FROM THE UNDERSIDE OF THE MACHINE.
