CheapCNC homemade copy

Made the router below over the weekend after seeing the CheapCNC photos. Could not find MDF in my town, I just used plywoods.

Holly Sh_ _! you made that In one weekend! Wow that is great! Good job! After seeing that cheap cnc web site i couldnt believe what they were getting for a price for there unit!

looks good and quick too what kind of driver board you going to use and what type of leadscrew is that. I wish I could build something that fast mine is taking months

[abasir]

I made my own driver board (inside the black box with meter) with LM18245 (2 Amp continuous)+PIC16F624 MCU (for step/dir and microstepping).

The leadscrew is the normal 1/4-20 stud from normal hardware shop with two nuts to minimise backlash.

Additional photo to those wishing to know more.
The router motor (Dremel equivalent) is mounted using normal TV antenna clamp!

Photo showing 'locked' nut againts the roller bearing to prevent leadscrew freeplay. Roller bearing is epoxy glued to the wood.
Yes, the small switch is my limit switch.

Regular pipeclamps! That's a fantastic idea. Here I am trying to drill perfectly aligned 1" holes through 1 1/4"oak pillow blocks (trying to make the pillow blocks relatively square to start with) and then you come along and in one weekend ... Why I outa...

No really your machine looks great. Hope you don't mind if I samelessly copy your pipe clamp idea. The amount of work/frustration it will save me is incredible. I'm off to C.T. (Canadian Tire)

By the way ... When drilling the holes for your shafts how do you ensure parallelism? Is it anything more than stacking the two plates and drilling both at once?

[abasir]

Copy all you want. We are here to share experience.

This is what I do to ensure parallelism:
1. Stack 3 plates together and I used stapler gun to make sure it doesn't move (wood clamp would work but I don't have one:0)
2. Drill the hole for roller bearings + motor shaft using _drill stand_.
3. Remove 1 plate then drill the shaft holes.
4. Mount the plates + shaft + bearings and start fixing the u-clamp.
Whole thing (3-axis) takes less than 1 hour.

One more thing to share.

The place I bought the plywood could not cut with precision so my plates are slightly off in size by 1-2 mm. To overcome this, the worktable is 'screw+nuts' adjusted on the four corners to the correct height before final fixing. Now, the table is 'flat' againts the router bit.

I must be missing something what typr of pipe clamps are those, what is there normal use, dont say clamping pipe LOL. I dont think Ive seen those before where do you buy them cant see real well in picture
Thanks
