Remora - ethernet NVEM / EC300 / EC500 cnc board

Hi Guys, 
as easter project, i tried to put 32v von my nvem v2... damn it ...a capacitor blew up
can someone please give the values of it?
i can not read it anymore.
thanks in advance
best wishes

Hello
I ran a test to verify the problem I have,
that is: on the A-AXIS output (join 3) there is no signal

I enabled all the axes in the .ini .hal file inverted in the nvem-rt1052.txt file, the joint 3 pins (A-AXIS) with the joint 4 pins (B-AXIS)

it happens that joint 3 and joint 4 are inverted and on the B-AXIS output I find the joint 3 signals working, while on the A-AXIS output the join 4 signals do not work,
on the C_AXIS joint 5 output the signals work

it seems that the A-AXIS output on the NVEM card is physically interrupted, is it possible?

Hi,
I have prepared the hardware to check if yours is a hardware or software problem. Could you please tell me where you got the files from?
I have now used this link: github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
and the machine works even if there should be a better setup for the servos, but the signals arrive for XYZ.

hi
thanks for the feedback,
for testing I downloaded again from the link you posted, I loaded the configuration file that is in the folder, the I/O seem not to be suitable for the NVEM, however dir/step are suitable,
my result does not change XY works, Z pressing forward and backward only turns in one direction, the dir channel does not work, and I think that by also setting the A axis it does not work.
I think it is a hardware problem.
thanks

Hi, I used your configuration by copying your files to mine and all the axes work. Did you get a board with only 3 axes? Or do you have a 6 axes? Because the manufacturer could have not soldered the bga. Or simply there is some faulty circuit, I don't know if there are opto-isolators in the output but there should be.
but I didn't compile any hal file like this  "nvem-rt1052.hal"

Hi
the board is a 3-axis, but I don't think it depends on that, I think.
Ultimately, on six axes XYB working, Z and C turning in one direction, dir doesn't work, A doesn't work.
I haven't had any luck....
this is the second board, the first one in understanding how to flash it I must have made it unusable, I can't get it back.
I don't want to buy another one, never mind.
Thanks for the feedback

try this: pair the contents in this dir:
github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
download this:  github.com/scottalford75/Remora-RT1052-c...xCNC/nvem-rt1052.txt pair your files:nvem-rt1052.hal,nvem-rt1052.ini
then: 
and try again please

I try again and C turning in all direction.

Thank you
it's not a configuration problem
I tried the procedure you described, but nothing changes

 

XYB works, ZC dir doesn't work, A doesn't work
it's a hardware problem.
Thanks

can you desoldering and test this? or replacing it shouldn't cost too much.

I guess the culprit is that chip, I already tried to redo the soldering, but it was no use.
I have the first unusable board with two of those chips, I'll see what I can do, I've never unsoldered/soldered chips like that.
thanks
