I do not I use the axis for only one type of work ( visible on videos ) and this doesn`t need homing. I have no need for better axis.

thank you Pit for the Quick Reply

you write:O1 and O2 are future outputs , one is for the break solenoid (12V).....

where do you now connect the solenoid for the break or work you without Brake?

thanks

[pit202]

O1 is for the brake I sometimes use it , O2 was used for the debuging and ligths when a frame error detects, and I still have no idea for other use or O2 so I leaved as is.

thank you Pit

with the schematic from you can i now easy build the interface thanks very much

to complete the interface i need the source code of the atmel?

is possible to post the source for me?

thanks

[pit202]

yes, I`ll post the source and hex at work, maybe someone will do upgrades ;-)

yesterday I recive my harmonic gearbox , now I see hope for my 4th axis, zero backlash
I attached some videos from youtube , and my gearbox photos.

Cool video.

That first video looks like one of the fixture tables I worked with back in 1997, we built tractor trailer suspensions, is that a mig robot I see (in the background)?


.

[pit202]

it probably is , according to comments it is a welding station.

I attached my code for serial axis.

thank you Pit for the source

now i wil start to build the interface

one Question
its possible for you to make a pics from your assembled interface from the top and from solderingside that was wery usefull for me to build a similar pice

thanks

hi pit

I'm a partner of walter, developing the electronic interface for him.
I'm a trained electronics engineer, so I think this little interface
shouldn't be a problem.

I just have two questions about your circuit.

1.
What for have you used the optocoupler OK2? For me it makes no sense if you use the same supply at the other side of the OK2. It might be for having an open collector output, but why have you taken an opto but no standard open-collector-driver?

2.
In your shematics I can see, you are using no standard RS232-driver but a little network of lots of components. I think, this circuit doesn't comply with the RS232-standarts. Wouldn't it be much better if you'd replace this RS232-circuit by a standard RS232-line-driver (like MAX232)?

Anyway it's a very nice project. If I can help you with the electronics just ask. If I developped a new interface, I'd use a SiLabs-Microcontroller because I'm very similar with them.

Thank you for soon response.
