Some progress...

Milling oil grooves

Ballscrews!

Testing the movement, and they are silky smooth...
I just set up my second ESS with a new Windows 10 PC . The PC is a refurbished HP (basically new) I got off ebay for 85 bucks. I run Mach 3 and I'm trying to migrate to Mach 4, but I know Mach 3 so...
I looked at a used one once, its basically an RF-45 clone with a poorly designed conversion. It had the ballscrews directly connected to the steppers on X and Y with some crazy connection that had...
Too bad they shut down backpage!
Well, youv'e inspired me to get moving a little anyway. I finally decided to forego buying a finished VMC and tore into my RF45 clone. I got the ballscrew kit for the PM 940 from Heavy Metal CNC, and...
Has anyone else had any issues with the LHB04B pendant? I see they are also sold at CNC4PC.com, just curious what others have experienced with this device? Does it operate well and work similar to a...
Set it to zero just off the switch while your in machine coordinates. Thats what I do anyway. There is also nothing wrong with moving the axis manually while off power and starting up with it where...
Found this on ebay:

I am sure you will probably have to drill and tap some holes, but at least you dont have to bore...
Those are industry standard drives,and I guess you have tach's already on the motors? The mesa will have to handle the encoders. Its more than I would be comfortable figuring out, but thats the way...
With a standard single lpt port setup it is convention to have three +x,+y and +z limits on pin 10 and x -home/-limit on pin 11, y home/-limit on pin 12, and z home/-limit on pin 13. This way you can...
By the time you are done with power supply, drivers, tuning, etc. and you will have old technology, if it were me, I would just go with some good used AC (brushless) servos from allen bradley,...
Try just blowing out the swarf with an air compressor. They go everywhere, but it will get them out of the way.
Anyone want to buy half a cnc router? Sell it on ebay!
Its news to me that they are even available here in the states. I am presuming you are here in the US also? Their specs are impressive. They are certainly expensive, but probably merited,...
You guys across the pond have different options than here in the US, but the main thing is going to be your experience and time at that price range. You can do the critical tolerance drilling,...
The motor showed up yesterday, in a nice little chinese shipping box. It looks to be well made. Im in the middle of converting to cnc, and i figure now is the time to put it all together with a vfd...
You think it will be ok setting it up with the max hz at 100? And set the current to its rated max?
What about the VFD, should I get a Huanyang or use this little one? It only has 34 parameters,...
So, the VFD came in, fast, its about the size of a pack of cigarettes (not really), I'm going to use it on this little 400 watt 3 phase lathe I have and go ahead and order a 4 or 5 HP Huanyang. ...
I went to their website, and it is confusing. The description of the 3019 cnc ready lathe says -
"Full Blown CNC Lathe with 1/2-20 Leadscrews, ER16 Headstock and DSLS closed loop control system...
Nateman! Its good to see your still kicking! I always wondered what happened to that IH head you were putting together. I,m trying to finish some of my projects from way back, I get it, I have a...
Definately, dont move whatever it is. They are BLDC or "AC" servo's almost certainly, but without the MFG. spec.s, you will have a hard time trying to use them. There is no identification on the...
Got this ordered, any clues on how this will perform on my RF-45?
https://www.ebay.com/itm/165176176624
I thought it was a deal for $119.00 and I got this VFD for it.

It is hard to tell from the pictures how rigid it is. If you bought one off of ebay from a well established seller with a 30 day no questions asked return policy, you could check it out anyway.....
What is wrong with the 4020? Do you know the footprint, approximately? I'm in South Orange County.
In the picture it does not look as though the table rotates.
You really need some definitive budget. What do you believe is "on the cheaper side" ?
"Che bella machina." You can tell everyone you have an Alfa. My Dad had an Alfa Romeo when I was a kid. What a car.
Anyway, it looks like it should work fine, and has everything to be desired,...
You could make some money selling the plans to that little tool changer. I should call Dyna and see if they would sell a copy of them.
I have a couple of the Dahnaher (Kollmorgen) Smoothstepper drives. You can find them occasionally on ebay. All of the name brand stepper manufacturers (Vexta, Oriental, Pacific Scientific) make them...
