General Mach Discussion / My First Mill and first CNC upgrade

« on: February 10, 2009, 06:08:09 PM »

I am about to buy a Milling Machine, I have selected which one I want however due to its lack of CNC I plan to convert it almost immediately.

It is an Eastern Mill so I was planning to replace the leadscrews for ball screws and then fit ... servo motors on each axis.

Two questions:

1)  I am only looking at Servos due to our 'workshop guy' at work recomending them over steppermotors...is there a real gain?

2) Can mach3 controll Servos?  If not what would be a good set of stepper motors? (I am in the UK)

Thanks,

Andy

Thanks Hood, I will give it a go and let you know the results.

It works...I have threads...I have not tested them yet however they look like threads and good ones at that!

I just need to make a metal disk rather than use a bit of card board.

Thanks,

Andy

p.s multi start threads need indexing...I will have to wait for that.

Thanks Hood, will give it a go an let you all know the results.  I imagin that multistart will need indexing some how...

Thanks,

Thanks Hood it is that exact switch.

I will give it a go this weekend...cant wait!

I have ordered a 60 degree threading tool with carbide replacement tips, will this do variable pitches? I would like to do small threading pitches such as 0.7mm and 1.5mm.

Last question is can I do multi start threads? with this system?

Hi,

I am planning to fit an encoder (optical) to my sherline and using a slotted disk to detect what speed I am going at.

I have little electronics experiance and thefore have asked a friend to help me!

He would like to know what pin to connect the encoder to on the parallel port?

I will get this machine threading eventually.....

Thanks,

Andy

p.s A big thanks to hood for recomending and showing me this method.

General Mach Discussion / Re: Syil C6 Lathe thread?

« on: October 05, 2008, 04:15:39 PM »

Hi,

I have found various optical sensors however connecting them to Mach is somthing I know nothing about.  I currently have a mach setup with a sherline lathe,  if I could get that to screw thread that would be great.  I did find a company selling servo versions of the sherline, however I would have to buy the whole lathe again.  Which is why I was looking at the syil.

If I had an optical sensor on my current sherline cnc lathe hooked up to Mach, would that thread?

If yes then where should I start looking for an optical sensor that can talk to mach?

Thanks,

Andy

Thanks Hood,

Should I just email that to the supplier and ask if this is the case?  Does anyone else own this lathe and know if it can thread?

Thanks,

Andy

General Mach Discussion / Syil C6 Lathe thread?

Can the Syil C6 lathe thread under CNC?  Will it work with Mach 3?

Thanks,

Rich,

You are a genius,  the code is generated by an old copy of oneCNC.

However it has worked.  What does that "reversed arcs in front post" checkbox do?

Thank you,

Andy
