I homing and tried to make x and y work. But all of them only move in the + direction and not in the - direction. For what reason?

My printer doesn't have a z-axis limit sensor.
So I want to match the nozzle and bed manually and let you know the zero point. Is it possible?

What is the maximum command pulse train for duet 2?

@phaedrux Thank you. But I have a question. Where is pin3 on the duet 2 board? Is it pwm in the wiring map?

When extrusion occurs, the air sol valve and water pump are operated. Is it possible using relay 5v module on duet2 board?

@dc42 I will set the timing from 1us to 4us and respond after driving. Thank you for letting us know!

I finished wiring to operate the AC servo motor with Duet2 Ethernet + Expansion Board. For commissioning, the movement from 0 to 100 is confirmed on the DWC interface, but the actual motor does not move. What is the problem?

I matched the subnet mask and gateway, but I can't connect to dwc..

what's wrong..?

Then, if the minimum value x 0 and the maximum value x 150, is the zero point x 75?

For example, the minimum value is
x 20 y20 z0.2
Maximum value
x 100 y 100 z 10
What if it is?

For example minimum axis limit (example-x axis)
If this is 20, is the origin of the x-axis 20?

To use a larger range in the arm of the polar printer, we will use those nozzles connected. Should I use the offset function? The actual rail length is 4m, but it should be 6m when moving 4m. How do I do it?

Is there a way to simulate polar 3d printer motion? For example, like previewing motion in a slicing program.

@Phaedrux
I have looked at the documentation for polar, but there are some things I don't understand.
Since the movement of the arm is linear, it makes sense to apply steps/mm, but since the movement of the turntable is circular, I think it should be steps/degree, not steps/mm. Is this correct?

Is polar's x-axis turntable?
If it is turntable, should it be converted to steps/mm or steps/degree?

M92 X80 Y80 Z4000 ; set axis steps/mm
M92 E420:420 ; set extruder 0 and 1 steps/mm

Knnn Geometry class, 7 = Polar

Raaa:bbb Minimum and maximum radius in mm. If only one value it given it will be used as the maximum radius, and the minimum radius will be assumed to be zero.

Hnnn Radius in mm at which the homing switch is triggered during a homing move. If this parameter is not present, the homing switch is assumed to trigger at the minimum radius.

Fnnn Maximum turntable speed in degrees per second

Annn Maximum turntable acceleration in degrees per second per second

I am trying to connect the power of duet 2 wifi. Bed heating and nozzle heater will not be used.
Please advise if it is stable to use 24v (?)w(power supply).

....I tried, but it comes out like this...

@bearer How can I download it?

There is no 3d file of duet 2 breakout board.
