My setup on my RF45 clone Milling Machine is LinuxCNC with a Mesa Electronics 5i56 FPGA and 7i76 Daughter Card.

Do you prefer Windows/PC based software, if so why?
I use LinuxCNC, the reason is,...

I custom order from Linearmotionbearings2008 on eBay. You can buy what they have listed on the eBay site or send him a custom order via email @ [email protected]. They made my...

If I were to do it all over again and I had the room, I would build a Granite machine. That said if you are dead set on a 45 clone, then get a Precision Mathews, they are one of the better machines...

I purchased mine through Chai aka [email protected] this is the same vendor as seen on Ebay. For some reason the double-nut Single Flange setup he doesn't list on ebay at all. Ask...

Per the manual for the TB6600: Operating temperature = -30 to 85 °C
I operate smaller servos at higher temps in a 3D Lab. They have to be cooled and kept dust free with dry compressed air because of...

It is strongly recomended that you do not use a laptop for linuxcnc. I would encourage you to pick up a small atom board instead.

Readings across each of the connections should be consistent. what you have is not. Doublecheck them and if they still read different numbers like what you already listed then there is probably...

Labor day weekend over in China, you may hear from him in the next day or so.

the ballnut is really the deciding factor, you should be able to cram the 20mm in the X and Y. a 25mm should fit in the column easy enough. the column overall should be the easiest to design. here is...

the first one you posted is the style you would want. to adjust the backlash(which is supposed to be preloaded) you would put a different size spacer or some bellville spring washers (which requires...

Ivette, sounds like you have the double nut that is a flanged nut with a shorter non flanged nut by your description. If I'm correct than you will want to remove the locking tabs and insert some...

Possibly, though he only indicated "benchtop sized" but not what his actual size restraints were. budgets are always a royal pita to maintain and sometimes there is more flex than one is initially...

fixed my response a bit. I would highly recommend the 3 phase. Better part finish, more torque etc.. if you order the Charter Oak 3 phase is an option with VFD installed. also a CNC upgrade kit later...

220 is not a big deal really you can run a transformer and a VFD for 220v convert to 220v 3 phase.
are you sure you cannot do 220? It can be run on the exact same wiring, your breaker would just...

My setup as an example: The VFD is in my case but is electrically isolated via grounding and strategic firewalls within the case. The drives also have a firewall isolating them as well. Although I...

So I have one of those 10 way manifolds from ebay for my one shot oiler system. Annoyingly the damn thing floods my Y axis ways and gives a good amount on my X axis ways and y ball screw. But for...

Finished up the Y axis today. I wound up with a few snags to work through. one of which is the Pulleys I purchased did not have the option for a flange. I knew this might present a problem later, and...

If you're not running Mach then Mesa hardware is also an option

yea I bought the anti-backlash (aka doublenut) screws. I had to completely redo the spacer on the Z screw, so in theory the nut should not be the cause at all, but anything is possible. The spacer I...

yea I don't recall any alignment pin. the original acme nut. just had a slight protrusion that inserts into the slide and the large M8 bolt threads into that from the slide face.

I can turn the...

To clarify we have already adjusted the gibs properly with a dial indicator. We are trying to identify other causes of backlash at this point. lubrication is also ruled out.

yea the shaft turns about 3 teeth from one extreme to the other with the gib locked down and about 80lbs of torque applied to the pulley. The ball screw does not move longitudinally my bearing mounts...

Also check your local craigslist for similar machines to get an idea of what kind of price range you can ask for.

Sounds like a slight tuning adjustment may be needed.

with the gibs locked down I get backlash at the pulley even after torquing down all of the bolts. either the slide is flexing or my mount that I made is flexing, possibly a combination thereof. It's...

Plenty of users have used glass scales without any complaints. As long as they are mounted in a solid level position so that chips cannot get into them you should be fine. Things that will kill your...

Those Sinpo scales are glass encoders with a TTL output, 5um/0.0002”. They even give you a snazzy serial connector. should be simple enough to wire them in.

Well I made my own bearing blocks since I read early on that the one chai provides are crap. plus I have double nut ball screws so the play should be non existent especially since I rebuilt the...

Finished up my Ball screw mounts today. I had some strange troubles with my Z axis randomly diving down during my cutting operations though. A bit of a nuisance. Accuracy wise I kept everything close...
