I`m guessing you havent been checking to see what problems everyone has had with their NVEM controllers, seeing you havent answered any more questions. People should steer well away from anything you...

Hi everyone. Just asking if this is feasible before I got to all the trouble to build the setup. I have a small cheap lathe upgraded to CNC. It dosent get used much these days as I have access to a...

Thanks Freff I`ll give that a try. I could prolly make my own but I need to be able to fit them to a ballscrew that I am fitting to my lathe so its a catch22 situation. Darebee..you have no idea how...

Hello everyone. does anyonw know where I can get some 12 mm X1mm nuts ?(yes its definitely 1mm not 1.25mm nuts I need.) I am more than willing to pay for them if anyone has some.

Thanks.

Hmm..I think i found another hole im my theory about using pics to link encoders to steppers.It would be feasible to control one stepper that way but I guess would be a problem when integrating X,Y,...

Yeah. you could be right, but steppers and encoders on ebay are a lot cheaper than servos, and if a cheap PIC could be made to act as a Pseudo closed loop it would be just as good for a lot less...

Hi Robin. What a brilliant idea. When you get it right you will have solved one of the major issues with using steppers. i would be interested in the outcome.I had another thought that if i had the...

I`m not really sure.I was thinking along the lines of another pic or such countin pulses and comparing the result with an encoder (sort of like a virtual closed loop system) and if it misses steps...

The usual method is to mark the motor's starting position accurately, then run a torture test (i.e. a test that runs the motor at various speeds back and forth until finally return ing to the start...

As to using the PICs with quadrature encoder, I'm sure the little 8 pinners I've used lack the necessary hardware (you'd need a couple of fast counters to ensure no pulses were lost). The ones to use...

I'm Bill Todd, based in the UK in Colchester Essex. My principle business is electronics, but I've always had an interest in home machining.

I have a few projects on the go that might be of...

Yer i will admit it is noisy but for the price it wasnt a bad buy in my opinion.I will probably get a better one later but i would rather stuff up a cheapie drill mill while trying to learn how to...

Hi Ajax-oz First let me state that I am by no means an expert. I am embarking on this whole project as a learning experience. I had only ever used a manual mill years ago for a couple of months...

`Lo there Ajax-oz. I`m just down the road in Reynella. I bought a chinese mill and so far have turfed the lead screws in favour of ball screws. Also have mounted ( in a dodgy way ) 900 oz steppers...

Bummer... I work arvos The PIC side of things would have been good as well..

I might be wrong, but if you run 6 wire steppers as bipolar(not using the centre tap), dont you have to half the amperage ?

Hi Bones.
I used to ask lots of questions to the guys at ozmestore before the auction ended and always had a response, although sometimes it took a while. Sorry to hear you haven`t had the same...

First plan for my CNC milling unit is learn how to use one.. hehe. Also want to CNC my BV20 lathe. As for what I am really going to do with them, I Hope to make dog agility equipment with them. I...

Hi All. I live in reynella. I bought a new chinese dovetail drill mill ( $1000 cheaper on Ebay than same mill in Total Tools shop !!! ) Now comes the hard part - taking out the crappy lead screws and...

Hello everyone. I thought I would respond to your call to newbies who haven`t posted. My name is Mario (but most people just call me Marz ) and I live in Adelaide, South Australia. I dont know about...
