Sounds like Skyko


General Mach Discussion / Step and Dir to Analogue converter
« on: May 10, 2007, 03:17:58 PM »
Are there any other suppliers of step and Dir to analogue converters? I get no reply to my emails to Skyko (Pixie)


I had a similar problem when I first started and eventualy traced it to the DC power supply that I was using to power the logic to my servo's (Panasonic) this despite the fact that I was using diferential signals for step and direction.

Hi there

I am currently using Panasonic servos for a lathe, but they accept step and dir inputs. They take care of themselves and call an error if they lose position. It is also possible to use a converter board which takes step and dir inputs and converts to +-10v to drive older analogue servo systems. See Skyko technologies.

Hi Graham I will run the threading again and post the code, as this is running as a macro, I could not see any problem with the post. It also did not do this on every pass, nor on the transition between cutting and the spring passes, but it did do it on every repeat of the job.

Has anybody had problems with the simple threading wizard? When I am cutting threads, sometimes the tool does not retract and then destroys the threads when it returns to the start of the next pass. I have not lost steps as the job continues normaly.
