@henriv - have you progressed on your project ? I think that would be very useful to have a cheap solution for a linear encoder...

I don't want to limit my activity only to cut something I may need to engrave as well.

But my first application would be to cut wood with thickness of 4-6 mm.

@cinematic2 - my question was if...

REading more about LaserCAd ( AWC608 Commercial DSP CO2 Laser Engraving/ Cutter Controller ) I have found out something that worries me :
Is it true that LaserCut does not work on windows 7 ?
...

Thank you both for your opinion.
Unfortunately I have to choose from LaserCut or LaserWork.
I have read somewhere an opinion that LaserWork it's more updated or is updated more frequently .
Also...

I'm about to buy a laser cutter/engraver. Supplier proposed me to choose from LaserCut or LaserWork.
Those are 2 different motion controllers.
Please advice since what should I choose since I...

Thank you for sharing with us Andrew.
From description it looks that it 's a product dedicated for pan and tilt web cams where are needed really small motors.

Like you have presented it until now seems to be doable by a hobbyist ...
I see it like a lasercut base board and few stepper on it. I suppose that troubles are coming on the moment when you start...

What a pity that you don't intend to build it.
I see that you're so opinionated about this.

I would be interested to give it a try but I am pretty sure that it's not that can be done in a home...

Discussion went away from PPM machines. IF you want to see errors on positioning of motor shaft. Put on shaft a laser pointer and measure positions on a wall. With a needle you won't see a big...

However I still don't understand why do you want to have a motor for each feeder.
Under those wheels can be a linear stage that will move a motor where it's needed.

I have just broken apart my inkjet printer-scanner and scanner was containing exactly the motor that are you talking about. However I think that It had a high number of degrees per step since there...

I respect your position ! In fact, at some point each one of us has to make a little profit.
More than that, you have published until now a lot of useful and directly applicable information. If...

This is really incredible ! - I was reading many times MAriss Freimass posts (in this site) and in his opinion there is no point to go under 1/10 Microstepping (that's why there are no Geko drives...

@SCSI - huge amount and verified information's. Thank You !

Regarding ringlight : I was attending to a COGNEX seminar - they have spent about 1/4 from seminar time to demonstrate and emphasis on...

If your friend that does recognition program would be so kind to give some details about the way how will implement recognition I would be very interested.

Hi ,
I am also interested in optical recognition solution. Hopefully using a cheaper imaging library - Leutron seems to be from Switzerland and probably their license will be several thousands of...

That connections are made at run time and not at design time. At very beginning I had a problem too to understand that. it's because same pwm generators are used to drive a H bridge in both ways.

Schematic it's here :
http://www.cnczone.com/forums/603365-post30.html I will find the Kicad source too .
Application it's exactly the same that given as sample design on Cypress site. Again I...

Hi,
I have to look for them. Has passed some time (one hdd damaged) and I has thinking that nobody it's interested in this solution.
Again compared with others drivers (even comercial) available...

latest post it's from 2009 . unfortunately this is not that alive ...

Hi Peter,
I have seen them already. Will you please elaborate a little about vision system of your "work" machine ?
You said that it has RGB led's. It is changing the lighting color often ? or is...

Hi Peter,
You said that you have finished your machine. Will you please post some pictures with your machine ?

Kind Regards,
DAniel

Nice ! Please keep us posted ! Where do you post more often here or on Adafruit ?

Regarding placement files, it's there any standard for them ? I plan to build myself too such a thing and I have...

Congratulations ! - could you please post some close up's ?
I can't see your cognex vision in action.
Did you managed to rotate the part partially ? You said some time ago that machine it's able...

above application it's based on psoc1. for an amateur it's a good choice. to compete with gecko it's a joke.
But I repeat it's far better than all the open source designs that I have found on...

Reading datasheet will give the most certain answers.
0.15 Ohm will give you maximum of 3A current per coil which is the maximum of what you can get from this chip.
3.5 A it's rated for very...

Ok : I use and usb microscope that I bought from ebay (his driver made me a lot of white hair...) Working distance seems to be just good.
Lighting probably needs to be replaced. Seems that direct...

Thank you for teaching. Indeed illumination has a huge impact.
I feel myself recharged : I will play again with OpenCV.

Image of your pcb it's very nice. I have tried a lot of webcams and cheap...

Hello Nisma,
Thank you for reply ! I understand that it's no solution that could be universal but I need / request a little guidance.
I have played until now with an usb microscope (probably it's...

A guy from Lithuania seems to sell some machines. However those have a look like home built
