Running UCCNC with a touch screen interface. 5500rpm dc spindle 0.55kW with index sensor added and a sprint 800 drive. x and y steppers replaced with 400 step per rev units. X stepper has a coolant sheild (that's what killed the last one. A...

Re: My machine improvements

I'd be interested to see pic and drawing for the TTS conversion Thanks Matt I don't have any drawings but I'll upload a few pictures shortly. It's basically a frame with a lever and a few belville washers. Because the machines so low powered I have got away with less spring pressure than they would...

Re: My machine improvements

Finally I have purchased a replacement spindle motor good for 9000 rpm and will swap out the spindle bearings at the same time. I have just acquired a Star Mill and plan an upgrade, it would be useful to know what motor you are using for the upgrade, TIA, Nick Ni Nick, I found a small SEM 0.5 kW dc...

My machine improvements

I have just done a bit more improvement to my starmill and thought it may be useful to others. The starmill is stated to have 170x100mm table travel. I had to replace my stepper motor on the x and lost 5mm. Since then I have machined down the end bearing block down by 10mm to get to 175 once the blo...

Re: Fenner Drive wiring for mach3

I received the new board yesterday but the machine had progressed to the naughty corner for the weekend. I will be back looking at it tonight so hopefully will make some headway. The drive I have is a Fenner 522A3700. Any understanding of the connections would be of use. Im very much out of my depth...

Re: Fenner Drive wiring for mach3

I belive the BOB was generating an isolated 0-10V however when hooked up it seemed to create a floating live which gave me a belt. What I meant to say is I used an optocoupler isolator to get around this. That worked. I'm very much at the stage of researching and muddling my way through this build s...

Re: All new electronics

Iron-Man - thanks ill have a look through it to see what you did. Is it a tachogenerator feedback that gives the spindle rpm control in your setup? i assume thats what ill be using to ensure threading happens correctly. Im also half way through a mill conversion, though im on a starmill not a triac ...

Re: Schematic Circuit Diagrams for the Novaturn

Thanks for the schematics, i am currently trying to build a new set of electronics for my novaturn as none came with it. I am looking at the spindle drive and the encoder feedback does anyone have any ideas about the missing page 4? Is the encoder feedback converted into a tacho signal?

Re: All new electronics

I have started making some progress with the lathe finally, i have been a little absent up until recently so seem to have missed that sprint drive. I will be running the machine on UK mains so the 180V wont be an issue. I seem to have hit a snag with the encoder feedback on the machine from the spin...

I am looking at using GRBL control and GRBLGRU as the main software. I am struggling with getting enough info on how the toolpost works. Any help ...
