Is there any way to have 5V Pulse from Duet Wifi ?
-
Hi,
Generally we are getting 3.3V Pulse from Expansions Pins.
so, Is there any way to have 5V Pulse from Duet Wifi ?
any other pins ? -
The Duet works on 3.3V logic so to get 5V logic you need to use something to increase the voltage. what to use depends on the application. what do you need the 5V for?
-
Our Fuji Servo Drives work on 5V Pulses only.
We are using Servo drive for one Axis.
We are using transistor circuit to get 5V Pulses. -
The external stepper breakout board uses standard differential line drivers, which is what the Fuji servo amplifier seems to want. The actual differential voltage is somewhat less than 5V, but that is normal when using line drivers.

Did you mean https://www.duet3d.com/Expansion_Breakout
this board we should buy to resolve the issue ? -
yes

Yes, I suggest you try that board. As standard it will provide differential drive, which according to the datasheet for those servo amplifiers is good up to 1MHz step rate (so T0.5 ought to be sufficient). It's also possible to use it in 5V single-ended output mode by changing the output wiring.

Do you mean the breakout board gives out pulse of 5v?
-
The breakout board gives a differential output of about +/- 3.5V which is standard when using 5V line drivers. It's also possible to wire up the outputs a different way to get 5V single ended drive.
