Widgitmaster mini

[henrikw]

Hey all
Just got my widgitmaster mini!
It´s not running yet, but I´ll continue in the morning I have to say, the build quality of the router is outstanding!

bad mobile pictures, but they´ll have to do for now

That thing is KEY-UTE!

What size are those motors? They seem kind of large for the router.

[henrikw]

Heheh, yup. Cute it is I needed something with a handy size

The motors are 205 oz/in from hobbycnc. Any disadvantage of having these instead of the smaller ones?

The controller is the 4-axis pro board also form hobbycnc. no need for the fourth axis yet, but you never know..

This is my first router so it´s a learning experience for me

Bad? Are you joking for Mobile Pictures those are great! Most of the mobile pics I see are the equivilant to the fuzzy flying saucer pics where all you see is black with a white dot.

P.S. Nice Machine.

Well, the pictures from my mobile tends to be a bit fuzzy when there is low light conditions as in the pics above..

Anyway.. cut my first couple of parts yesterday! Nothing fancy, just a spiral from the EMC2 examples and a wing profile from the vectric cut2d examples. It worked great!

Still, the inches to metric conversion bit is definitely one to remember, I thought I was going to take a cut at Z-0.25mm, but when that endmill plunged about 6mm down in the hard plexiglass I nearly had a heart attack

Thanks for replying people!

I've been wondering about motors for a mini router also.

Is bigger better?

I plan on milling PCBs and maybe some alum faceplates if that is possible.

Also, while looking at steppers, I noticed power supplies seem to be in the 24-48 volt range, but motors want 3.5 volts or so. Is this correct?

The motors don't run directly off the input voltage of the motor controller board. They run off the motor controller's output driver device and the voltage and current is controlled by this device.

Yes, thanks. Further digging I saw that. But thanks for confirming.

What I have not confirmed is bigger is better...
My thoughts are too big may be less fine? Of do you get better resolution with the smaller motors?

Take a look at some motor specs, I have 1.8deg /step and a 10TPI screw. This adds up to about 0,0127Inches per step. Any more than that and you'll have to go microstepping or a nice little gear.

Bigger is not necessarily better. My machine has Xylotex 425 oz/in NEMA23 steppers. The Xylotex 269 oz/in NEMA23 steppers don't have the midband resonance issues that the 425 oz/in steppers have. The 425 oz/in steppers have roughly the same torque at full speed as the 269 oz/in steppers if I remember this correctly. With a 1/2-10 1 start acme lead screw the 269oz/in stepper seems to be faster and less problematic. The 425 oz/in steppers have more low speed torque for driving 5 start acme screws though.

thanks, thats what I was looking for.
Appreciate both comments.
