Remora - ethernet NVEM / EC300 / EC500 cnc board

If the power supply can do over 2A of current, yes you can use the same supply.
And no, that 2A is not related at all to the 2A written on the drive.

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 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?

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"
