Hello,

has somebody running Pokeys57CNC with an AMB (Kress) 1050 FME-1 DI (digital interface) with the 0-10V Output?

The AMB needs +24V, 0V and 0-10V. There is no dedicated GNDi for the 0-10V. 24V and 0-10V uses the same GND. Pokeys57CNC only offers isolated GNDi for the 0-10V. How can I connect the AMB to Pokeys57CNC?

I tried to connect GNDi to machine GND, but then I always get arround 5,6V, even when analog out is not activated.

Do I have to connect it to another PWM out with a small circuit to generate the 0-10V with the same GND?

Thanks

Alex

I tried to set PIN 20 to PWM and give OemDRO 817 (Spindle Speed) as PWM out, but I only get 3,3 V and no PWM signal from mach3. When I use the Pokeys application, then I can set PWM and I can see the PWM signal with my oscilloscope.

Is there a problem within the mach3 plugin, so that PWM out is not working?

I build a small circuit with a LM358 to generate the 10V, but when PWM is not working, this is not possible.

Solution  was, to add a dedicated power supply for the AMB with no connection to the machine electric. Then it works with the isolated 0-10V output.

Now all is working fine.

I am pleased you have it sorted and thanks for posting the solution.

Hello,
could you explain how did you wired the AMB spindle to the pokeys57cnc?
i can't contol spindle speed
many thanks

To help , i found the solution.

Connect brown wire to PSU 24v+, green to 0-10v pin and you have to connect 3 GND :
- 24V PSU GND
- 0-10v GNDi
- GND from AMB spindle speed control (white wire)



Configure Mach4 with step to step tutorial from Pokeys57CNC

And all works well now

You were faster then I :-)

here is the schematic for pokeys and the AMB.

You need 2 dedicated power supplies. One for pokeys (6-28V) and one for AMB (24V). You have to be sure, that GND/0V is NOT interconnected between the two power supplies.

For mach3 set things, like in this post: https://www.machsupport.com/forum/index.php?topic=33174.msg230383#msg230383

Map PWM to DRO 817 in %, set Multiplier to 0.00417

For mach4 I have no info. Still use mach3.
