Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

That drive and board require Quadrature outputs, LinuxCNC can do that easily, but i have no idea if Remora can do that.
There are 9 or 10 stepgen types that LinuxCNC can do, and probably 3 of those should work.
And just to be clear that "drive" is not a drive, it is an array of Darlington transistors that can handle 500mAh, if i recall correctly.
Apparently there are 15 types now, just checked so i need to update myself from 2008! :)

Post your INI file please and we'll see what needs editing.

And yes, homing is a never-ending struggle for LCNC users - both new and old-but-rusty.

Hello, I managed to install the homecomp independently, and Linux CNC also started. The servos are also enabled according to Linux CNC, but they don't go into op mode, only preop mode. When I try to jog manually, a lag error immediately occurs. What's wrong? I'm using Stepperonline A6 motors, but they're the same as the EL8, just with a different name.

Run the "lcec_configgen" command and put the output in a file.
It will have all the pdos, but you can just delete all except the ones you need. So you need to figure out which PDOs you need to use.
It will also have all the numbers etc in the right places, so if you are lucky it can work.
At least use it as starting point.

Hi
with the steps described in the various posts I have successfully installed Remora on a NVEM V5.
I have a problem, joint3 does not run, I have deleted and reloaded remora four times, without success, joint3 does not run.
Tried a five-axis gantry XYYZA configuration, the XYY axis works, A (joint4) works, Z axis (joint3) does not work
the configuration file is the one in the LinuxCNC folder
nvem-rt1052.txt    join3 are "P1_27", "P1_21" ?

I have checked the entire configuration many times, maybe I am missing something

P.S. thanks again to Scott and everyone who made it all possible

 

I wanted to thank you now I have the connection with nvem v5 and linuxcnc, I see it because using the software stop the red led lights up. Regarding your problem I have not yet received either DRIVERS or STEPER is there a way to test the outputs without having these components? like led? or I have this small steper but I would not like to damage the board by connecting it:

work at 12V and 5v

I thought it was optional.


it is optional, but in your configuration in the.ini file you have called it
HALFILE = remora-nv-mpg.hal

if you don't need it comment it and don't install the component

Hi
i think you didn't install the NVMPG component here

I thought it was optional.
Do I have to install all of these then?:

sudo halcompile --install ./Remora-eth/remora-eth-3.0.c
sudo halcompile --install ./Remora-spi/remora-spi.c
sudo halcompile --install ./Remora/remora_lpc.c
sudo halcompile --install ./NVMPG/nvmpg.c
sudo halcompile --install ./PIDcontroller/PIDcontroller.c
sudo halcompile --install ./PRUencoder/PRUencoder.c

I don't have a raspberry

Thank you so much for your precious help

After homing X and Y, can I auto move to a non 0,0 location?

Category: General LinuxCNC Questions

I've recently gotten switch-based homing working on my 12"x12" DIY xyz mill.  The mill is the style where the spindle is stationary, and the bed moves in two directions underneath.  (I'm sure there's a name for that.)

0,0 is at the near left corner of the bed (of course), and after homing, with the spindle above that point, the bed is basically as far from me as possible.

I'd prefer it to home to 12,12 instead of 0,0, which would leave the bed as close to me as possible.  I've tried homing against the upper limits instead of the lower limits, with a HOME_OFFSET of 12, thinking that would help, but after homing at the near corner, the mill once again moves all the way to the other end, in order to end up at 0,0.

Is there a way to accomplish what I want?  If I can't convince it to actually home to the near corner, is there a way to automatically invoke an arbitrary move after homing?

Thanks. But it's your very first sentence I have trouble with. Given that the length of the bit is variable, there is no single actual lower hardware limit. It depends on how far the bit protrudes from the collet. Given that, what's the use of the limit? When would it do me any good?

First, stop mixing stuff, you're making it harder on yourself.
Machine is a CNC machine, tools are a separate topic that is used on CNC machines.
The limits are there to protect the machine, not the tools, but those same limits consequently also protect the tools to a certain extent.
Breaking a tool is not the end of the world ... or the machine in this case, breaking the spindle ramming it into material/table at full speed is a costly end of that machine.
Tools are dispensable, machine is not.
You have to figure out what works for you, while using the machine, trying to figure out tolling without using them is OK, but do not preoccupy to much with it.
Not sure my explanation is helping, but i went through the same process back when i built my first small vertical mill, turns out it's as easy, propping something up when tool is short, removing vise when tool is long, moving the spindle mount, etc, so there are options, always.
