How do I set up the motor settings for a tangential knife A-Axis? And how do I jog the knife to turn around? Lastly, how do I home it without an encoder to keep the knife in its same position each new run?

And I already set up my motor to make it oscillate up and down with step/dir spindel setting. But I turned on the spindel button and nothing happened.

I am not sure if this will help but i will try.
The tangential knife we use has a homing switch.
After it has been homed it knows where it is.
If your tangential knife is trying to turn too rapidly it could loose steps just like any other stepper motor.
That is the only reason i could think of for needing an encoder.
It would be better to set the velocity and acceleration for your knife correctly.
If you set up the tangential knife rotational motor to be motor A use the a+ and a- buttons to jog it.
I can not help you with the step and direction spindle setup.

Wow Bill_O,

Prior to purchase I asked about the homing of the tangential knife and you said no encoder is needed because it automatically homes itself without a homing switch! Now you say we need a homing switch.

if you do not have a homing switch you can set it to home in place.
I do not recall telling you it homes automatically.
I have no idea why I would say that.
It all has to do with how you set things up.
An encoder has nothing to do with homing.

Bill_O,

"
So it is an absolute encoder?
The knife should be able to home fairly fast and it should not need to be homed between jobs.
You do not need an encoder for current angle position.
You do need to start with the blade in a known position.
Most tangential knives use a homing switch for initial position.

I was under the impression based on your statement that it don't need an encoder to do the homing. But you clarified in your recent post that if I use home in place, it should work. Thanks.

Once again you do not need an encoder.
You can use a homing switch but you do not need to.
What you do need to do is start the knife in a know position on its rotation.
A homing switch makes that easy but you do not need it.
