For those interested and like to tinker, I found that these ultra-cheap IR transmitter/receiver circuit boards

Thanks Russ...
closing a connection between FOR and COM will start the spindle. To stop do I just open that connection?

I have the common Haunyang VFD and the 2.2kw water cooled spindle. After several years use the start/stop "buttons" on the VFDs front panel are starting to wear out, so I'd like to add external...

I have my CRP4848 built but having a bit of trouble getting the X axes bearings adjusted. My Y and Z axes are smooth as glass though.
I get a little binding here and there as I slide the gantry back...

I haven't weighed that spindle but I don't think it weighs much more than 20#.
Placed the order for the CRP4848....informed of a possible 3-4 week lead time. Business must be good...

It sure does help! I'll place my order today..

I'm considering the CRP 4848. A bit gun shy though because I just bought a $3k machine that turns out I can't use. I have the Chinese water cooled 2.2 kw spindle which is a bit heavier than the...

I can scrounge another motor and driver and yes the cw230 have 36 volt limits.

I have 3 each 425 oz nema 23 motors, 3 each cw230 drivers, a 30 amp pwr supply, PC w/ mach 3.

I've emailed joe about this but will post the question here too...

I just ended a bad relationship with a CNC kit sold by another individual online. Bought it for using Vectric's V Carve Pro and...

I just built the buildyourcnc.com Blackfoot table machine. My plan was to use my hobbycnc pro driver board and the steppers that I had used on a previous smaller machine....turns out they're not...

does a standard router mortising bit work ok for evening the surface of a table's spoilboard? my spoilboard is made of rather soft doug fir. ive seen some that look like fly cutters used in metal...

Another question about the 2.2 kw Chinese spindle I just received...

How much cooling do I need to provide. Will just a pump In a 5 gal bucket suffice or do I need a radiator of sorts? Automotive...

"Pick any two"; Now that I understand...even when you say it in Canadian.
Funny though, the diagram shows three fused lines going to each R.S.T. and that's what had me baffled.

I'm looking at the manual ...it says

RST INPUT CURRENT IF THE SINGLE-PHASE SOURCE MEETS TWO WILLINGLY

And on another page

THE POWER SOURCE IS PUT INTO THROUGH THE R.S.T TERMINALS. THE 220...

Just got my 2.2 kw Huanyang inverter and spindle. Referring to the manual R, S, T are the power input terminals, but it doesn't say which get the hots or neutrals. Can help but think it...

I bought 3 of these motors a couple years ago and they've set on a shelf until I just now found a use for them. Trouble is I've lost the data sheets on them. I've searched google with no results....

yes, i'll take a look at other options. i have the y & z axis all ready to go - just need to get the x going and i'll be routing wood again.

thanks for the links...good concise info.

thanks ross!

i took a look at those glacern linear bearings and rails and they're scratching me right where i itch. :devious:

a couple years ago i built a cnc wood router that worked well enough to get me some work with a local cabinet shop doing routine tasks like cutting recesses for lock sets and engraving designs on...

Last night I got in touch via email with a friend who's a physician and a dedicated garage tinkerer.

Told him about the laser idea, and he replied "wish I had known, the hospital here just...

Not a bad idea....

what I'm after is a cheap (like me) way of moding my router to toast wood with a line of reliable width and color. I figured a low power laser would do the trick. I saw the...

I've built a couple CNC wood routers - with my last one being the one I think I'll keep for awhile. I built it solid and it's just what I wanted and needed.

So that leave me with my...

I'm building the SolSylva Belt Drive wood router - or at least something close to it. Using the plans as a general guide, except I strengthening some of the Y & Z parts to avoid flexing - mostly by...

On my homebrew CNC woodrouter I'd like to control the motor via a solid state relay via a spare port off controller board. I see a bunch of these relays on eBay but many list the specs which say they...

thanks lee - I'll take a look at the link.

Looking for one flex coupler - bellows style - to go between my Z stepper and the leadscrew.

Need 1/4" on one end. I'll be using 1/2" acme rod as the lead screw and can turn its end down to...

After having very good success with my first home-brew router I've decided to build a larger one. To large I think to use leadscrews for the X & Z, so I'd like to try belt drive.

Can anyone give...

I have a home-brew cnc router now with a x-axis lead screw that's about 3' long. It works, but I'd like my next machine to have a longer bed and I'd rather not rely on a screw-drive. I'd rather go...
