I have my 7i96 working with a CommanderSK VFD over RS485 with hm2_modbus. (See attached)I write two registers using the init section but I haven't figured out the syntax to read registers in this section. Could anyone provide an example of reading registers during init? I'd like to only read the rated rpm, amps, etc once and I need the values in hal.I would also appreciate an example showing how to set the HAL_FLOAT scale factors. (in the .mbccs) I am currently using 

The physical PKTUART pins are assigned in the firmware source (the PIN_XXXXX.vhd file that was included in the zip file)
 (If that's what you meant)

That should work!

Do you need to assign the pktuart pins when you build the firmware?

If yes, the Mill with 7i92 has open connectors on the 7i85S TB1 TX6, TX7 SRX0, STX0 and all the odd I/O on the 7i75.

The Router with 7i92T supports a spindle, laser, and bunch of pins reserved for plasma.
P1 and P2 are both configured as G540 but P1 is actually connected to 7i75 card.
The pins I have unassigned are P1 gpio.029, .031, and 0.033.
The router is working fine and won't gain any functionality so an update is much lower priority. Really just a wiring cleanup so let's wait before putting new firmware in that.

I will try to get the  7i96d_7i85p_pktv3 installed today, otherwise it may be a week before I get back to it. 

Thanks!

It is working. Thanks to you and @dm17ry -- it runs easyli.

Of this is a common complaint,I could add this as an checkbox option in master branch.

As far as other wanted/annoying behaviors - feedback welcome.
I won't guatemtee you always get what you want but usually can at least help with customizations

I think it's a bit of a shame that they rather create a new version to have a reason to raise the price instead of fixing the bugs in version 7.
 

Hahahaha thats defenetly the case with 4 m/min.
I will propably leave it as it is.
Originaly it has also 4 m/min.

Hi,

I have no experience with CiA homecomp, but if I have a look at the comp source code here , I see that it creates a "joint.%d.request-custom-homing", jno" pin. Could the name be your problem?

Cheers,

Attached picture of the latency shows a Preempt-Dynamic kernel, not the required Preempt-RT kernel, so that will not work.
Try installing the RT kernel, if this works:
sudo apt install linux-image-rt

My Maho was originally only 1,5m/min with the Phillips 432. I have it set to rapid at 2,5m/min, and it is fast enough to crash before I react.

Yeah, that behaviour threw me.

Thank you, I will try starting with slow accelerations, max velocities, and longer step timings until I find a safe limit for it. I'm 100% sure there are no electrical issues because when I first got the machine, it came with a standalone controller that could run programs, but I am unable to run the ancient software to load programs onto it. The jogging feature on the standalone controller worked perfectly and was able to move all axes easily

That is quite interesting behavior by the VFD. If you have a "single ended" output (say 0...10V -> 0...70Hz), you would think that with the wires reversed, it would go to minimum allowed frequency or just refuse to start.

Anyway, glad you got it working.

Thank you!

I have already tried a bigger LATCH numer but it would just miss the index. Currently I usind 1.

Mabey I just leave it like that.

And what speeds would you recommend to cap the machine? I currently use 4 m/min. Is it recommended to go higher?

That should work!
