Mesa firmware versions and updating

Category: Driver Boards


I am correct in understanding that when I get a new Mesa 7i96S card, I don't have to flash any firmware to it, please?

Yes, you are correct, it comes already flashed with the normal firmware for 5 step/dir and a spindle with encoder feedback, so no need to flash.

Solution fo "hm2 error finishing read" with no good PC

Do all inductive loads switched by the 7I97T have flyback diodes?

Did you verify that IRQ coalescing is disabled?
verify with:

ethtool -c eno1

A a temporary test you can try pinning IRQs with

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

I had problems with the new version of the board at the beginning. Flashing the board was not possible. I have tested some ST-Link and also Daplink. Actually the board was defective. I complained about it and got a new one and bought another one. Flashing worked with both without any problems.

I set my configuration for the tool change because this is where the fault comes at 100% if there is something wrong.

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

If it is not clear in my question, then I will say again that I have tried it. Not one of the programs is connected to the STM32, not via SWD, not via UART, not via ST-Link, not via RS232. The board itself is working and works with Mach3. Perhaps all ports are closed in the firmware. Perhaps someone has come across such a thing?

1. if your PC has a Intel MAC, do you have IRQ coalescing disabled?

2. Do you have the Ethernet IRQ pinned?

 I would make sure that the 7I97T mounting hole near the RJ45 connector is grounded to chassis ground

When you get an error, what does:

halcmd show param *.tmax

report?

I did a continuity test on the 7i97t at the fasteners, it's not grounded.

below are videos of my errors. On one of them, the turret doesn't even launch before the error message.

the other is during rotation.

Is there a list anywhere of the required changes please? If those changes reduce the latency then may be the graphics card might be worth a try.
thanks again
