Hi

I am trying to implement DC brush motor control by using Atmel microcontroler (providing PWM) and mosfets.
Because microcontroler cant provide enought current for fast and full switching of...

Hi

So if i want to accomplish two things: tell Turbocnc to make steps on 5V to 0V transition and to make direction changes before next step, then all i need to do is to set IsActiveLow=True.
...

Hi

I want to make sure my Turbocnc configuration is not losing steps on changing direction.
My stepper driver steps on transition from high(5V) to low(0V).
There is some confusion between...

Hi

I wanted to ask, is there a way to connect electrical components without soldering.
A silver paint for pcb trace correctures is easy to get - but can it be dosed precisely and will it hold the...

Hi

I dont understand how can continious flushing work.
If i understand pictures and explanations of wire-edm process, in the gap a delicate process takes place, first iones are bulid up and then...

I have been thinking of writing software for Wire-EDM too (in dos qbasic) to be able to experiment with.
Well it might be too complicated project for me, but i started by adapting free (G-code...

Hi


I am thinking about building and experimenting with EDM. I am conserned about power shocks damaging wires in walls, appliances and electricity meter, so i thought i could totaly isolate...

Thanks for your tips.
I believe i will find something suitable for me.

Hello

I am looking for place that sells cheap collimating plastic lens.
I know one place(Roithner) that has laser collimator lens, but these lens are too small for my aplication.

The lens...

Hi

I have one question. Does harmonic drive gearbox keep its position under heavy load when the motor that powers it is shut down - the way like worm gearbox keeps its position?


Just a...

One day i saw on TV how they make molds for garden dwarfs. It is complicated procedure involving many steps, but i am intrested in first two steps.
First they handmake artistic unique model out of...

30mm outer, 10mm inner diameter bearings can be bought for 1$ or 2$. I was looking for that kind of prices.
Anyway, thanks for help. Looks like i will have to change my design and use easily...

Winkelung are windings i think, and Laufer would be "rotor", that is, it is a complete moving part UNIT(as opposed to static part-the stator), like cart.

Now, this Isel diagram is like roller-coaster of comprehension to me: now i understand, the next moment i dont understand.




Put this way, this diagram finally makes sense. Congratulations to...

Hi





If i understand right, you are refering to the upper plate-the "rotor". My picture was only shematic, in reallity 4 units would be much more apart. To prevent shorting of magnetic...

Hy


I was thinking about feasibility of making linear stepper by myself. For now, it is all "theory" and none praxis, but i would like to hear from others, do you think the theory is right? Or...

Hello

I hope this is not totaly wrong forum.
I am looking for simple radial bearing of these dimensions: outer diameter 30mm, inner diameter 12mm or preferably more, height isnt importaint....

Well for now this are just considerations for distant future project. I saw oppurtunity to get long dovetail guides precisely manufactured for only a fraction of cost of used linear bearings(like...

Hello

I have a question about making of dovetail guides.
I found small manufacturer with professional cnc machine which can mill objects up to size 1m x 0.6m.
When I asked him, he told me he...

I am not sure whether this is the right forum, but I'll ask anyway.

I would like to use drilling-machine as a motor SOURCE for mill spindle, it would only power spindle by belt, it wouldnt touch...

Do you remember what brand were those controllers?


I am asking this question for two reasons: once to know how high-end mill systems achieve they accuracy, and secondly because I secretly hope...

Hello

I am learning about servos, and as I searched the forums, the only contex I could find INDEX pulse was in connection with limit switches, that is, to enable more accurate homing using limit...

Hello to all.



I am intrested in using ECM (electrochemical machining) for hobby use. As I understand it easier to control conditions in ECM than it is in EDM, so I think ECM is a first choice...
