I have been messing around with linuxcnc on the RPI for almost 2 months now, I have not got far with the realtime kernel but the rest of it looks fairly simple to do.

I have the system running...

I have been searching for more info about getting the real time kernel running on raspberry pi and found the thread here on cnczone, unfortunatly I have not found anything in terms of an easy compile...

From testing of the ball screws I have very roughly found:

Z axis) 0.07mm
X axis) 0.12mm
Y axis) totally shot to pieces, 0.5mm or more

The tests were only over a small portion of the middle...

Some more photos take at the weekend.

So far have:
1) got a general feeling of what is where on the machine
2) mounted the servo controllers in the cabinet
3) tested the Z axis quill ball screw...

Unfortunately i have had a nightmare with internet connection today and only now have been able to get back online, so I have not made any enquirys about ballscrews with suppliers and repairers.
...

I stripped down the ballscrew and it looks very strange over a 30mm section of the screw there are rough cracked edges to the ball groove.

Has anyone seen this sort of damage to ballscrew before??...

how can you tell it has been abused??

I am starting to try and work out what I should do about backlash in a machine I have just got for a hobby rebuild.

Does anyone know how to adjust ballscrews to remove backlash on this type of...

I now need a belt and pully and got a huge shock when I got a quote for a T10 type pully and belt.

Anyone have suggestions where to get cheap belts and pulleys?

I just finished my first foray into servo systems and am hoping to now get back to finishing the chester lathe by adding the ball screw to cross slide and roller screwnut to longitudinal screw....

Well I have finally got the drives working after initially thinking they were working (as shown in the video), I found some other problems to get it interfaced via the parallel port that required...

Just a quick post showing config of the 635 servo drive using easyrider.

I will when i get time show how I managed to fix the drives (thanks to the help of ssd excellent tech support).

Many thanks for the replies, unfortunatly they have not answered what I wanted to know, probably cause I didn't really ask..

Really the most important point and question of my original badly...

I am just a hobbiest, and only been doing a little metalwork for the last couple of years.

I have been under the impression that "carbide" tools were made from tungsten carbide (not sure where I...

Looks as though the servos may be salvagable, I hope to actually know for definite this weekend when I get some help in the workshop.

I may make a full post on "how to setup an ssd 635 servo",...

I'm a hobbiest and total newbie to servos, but it looks like I will be getting some SSD 635 servo drives and matched motors. I have had a quick look at the SSD site and found the 635 ref manuals and...

From time to time I search the internet for interesting information about metalworking and CAD/CAM/CNC. Well this evening I was doing a search and turned up the following metalworking info, and more...

I have been doing a little testing seems the mill axes are not a perfect right angles. I have measured with dti Y axis has 0.01mm in 150mm and X has 0.01mm in 200mm.

Anyone have any advice on...

And someone has left a comment.

I hope I may actually do something this weekend that is worth posting a progress report on the chester lathe mill.

I suppose I could add what have done even...

I have just been looking at soundproofing my mill/lathe and got on to a web site with good information http://soundproofingforum.co.uk/. I phoned and got some really knowledgable person to tell me...

This thread was a year or more ago, I cannot see any $65 iso 30 spindles available on a google search. Are they still available, where from, web link??????

I wonder if anyone knows what model the mill is and where to get spares?.
I am going to tell the seller to sort out the motor as he said it was working, but I don't know where to get the spares.

I have just probably made a rather stupid ebay purchase.

Never bought any used machinery before, only bought a three in one machine new and been engineering as a hobby for two years now.

Saw...

I found site full of soundproofing information @http://soundproofingforum.co.uk

They also gave some advice over the phone and prices for materials seem good.

They are a UK based firm.

Well last weekend hoped to get all three axeas working and do a full test.
Unfortunatly as always there were unforseen problems.

1) Jamming in Z axis, needs some further work, not sure why...

No it don't seem to work!

have you got another link?

It is actually an unbadged Vertex unit, I was disappointed with my supplier who has a catalog full of stuff showing Vertex labels on but none of what I ordered was recieved as shown in the catalog. I...

I soldered up most of the leads and put some pipe round the leads as conduits.
Did a little more work on what hopefully will become a tilting rotary table (made from a bit of rsj I found). Not a lot...

Been a while since I posted any info so just thought I would show some random pics of how things looked last weekend. Still loads of things that need to be completed.
A sort of list of whats in the...
