are these the correct inputs for rt1052 nvem?

net mpg-a encoder.0.phase-A <= remora.input.28
net mpg-b encoder.0.phase-B <= remora.input.27

I cant see where in the code the mpg encoder is  being read.

Thank you for your help and your hard work putting this together.

Cheers

I've just had another look at the RT1052 code and looks to be an issue with the encoder inputs. I'll put the EC300/NVEM back on the bench to test.

Hello. Anyone using INDEX Input on nvem v2? I have connected 0-5V from vfd to INDEX input nvem. Speed is not shown on the display. Something needs to be changed in HAL. ? Well thank you

The INDEX input is a digital input, normally connected to a spindle sensor. In LinuxCNC the HAL would need to be set-up appropriately as well.

I've just done a bug fix, pushing version 0.0.1 to the Develop branch. I've got NVMPG jogging working on the bench.

Thanks a lot Scott!

This is great work. Currently doing a Denford mill retrofit with parallel cards. I also have an emco little CNC waiting to get converted. Is it possible to get these to work with encoder inputs? Ie a toolchanger?. 
I'll also add Encode and QEI features to the list.

NVEM has two available QEI interfaces available for high speed counting on FHA + FHB and INP7 + INP8.

EC500 has three available QEI interfaces available for high speed counting on IN5 + IN6, IN9 + IN10 and IN12 + IN13. One of these is on TIMER1 so I'll setup the DMA step generation on TIMER8.

For a tool changer software encoder support should be more than adequate.

First your work is awesome Scott, I think there's really much support here than from the company. Do you think one of these input can handle the index pulse for the spindle PID on the EC500, I saw the V5 have a pin for this and but mine is older. I'm currently on mach3 but I really thinking about taking the big dive for linuxcnc!

I am using standard MPG and it not working with Remora, What does I need to do if it can work with Standard MPG? Thanks?
