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?

Thanks Scotta. I am a happy camper.

I remember seeing a way of funding you for your efforts but I can not find it. Can you please share a link.

Cheers

Great to hear. GoFundMe is still running.

Hi, can you explain a little more? What in particular is not working. Inputs, encoder? What is your HAL setup?

Hello,
first of all, nice work @scotta.
Im trying to flash ec500 (IMXR_EC500 2022-09-07), but I am unable to compile the files.
The direct flash for the first time does not work as I read in this thread.
I have probe visible in MCU Expresso but I have issue with lwip folder and I get about 40errors:

I have installed SDK_2.x_MIMXRT1052xxxxB_EA. version 2.8.6.
MCU is set to chip: MIMXRT1052xxxxB

Am I missing any library or something?


Thanks

I was able to flash precompiled firmware from github using pyOCD and I get pings now

Hi all.

A bit of a noob question.

I'm using the example remora-nvem.hal file

I have connected my estop switch to pin 20 of my NVEM board IE remora.input.20 but when I point this to iocontrol.0.emc-enable-in it gives me an error saying its already in use, which it is in this line

net user-enable-out <= iocontrol.0.user-enable-out => remora.enable

So what would be the correct way to set this up while not breaking something else.

Thanks
Alex

Hi, you need to create a E-stop chain in HAL using the estop_latch component. I've got a working example I'll need to dig out.

I'd appreciate that.

Apart from using the parallel port wizard, I have never really played with the HAL file.
Any insights into how it all glues together would be good.

Alex
