Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Perhaps it will give you more information in the terminal when you start with:
linuxcnc /path/to/config/yourconfig.ini

A small chance that this has to do with Remora

Help: How to run X and A axis with different feed rates simultaneously?

Category: G&M Codes

i want the A axis to be rotating continously at a given feedrate.
and X to perform back and forth motion (based on the material width that i have, so that i can acheive a side-by-side layup of the material) the material parameters are mentioned on the above reply of mine.

Do you want A-axis/spindle rotating at continuous speed?

Or do you want it rotating at a continuous material linear speed? i.e. RPM slows down as the number of layers increases?

The few commercial winding machines I've seen appear to have torque-mode drums and an encoder on the material in-feed.  Think encoder wheel with a tire pressed against the material at the infeed guide.  I believe they are in torque mode to ensure that winding tension is constant regardless of number of wraps.

I don't know all the programming, but the infeed encoder RPM value could be connected to the drum/spindle PID to slow it or speed it up.  And the position value would be used to move the guide shuttle based on a material diameter formula.

Not really G-code stuff, more like PLC stuff.

Hi,

As long as a unsupported driver is close to a excisting driver nr, we can write some code for it so it works.
I am not very familiar with servo's, but beckhoff EL- stuff is not that hard.

Just order it, no worry's. We are here to assist.

Hi,

will this version from your repository control an real machine with ethercat servos?

You may run the machine on it, but it's not for production machine as it still has bug's.
The halcore has no home sequence etc. The version is just for testing purposes.
However i have a full backup for you, if you want to test it.

in the previous videos there was an tool direction that i could use to control the tangencial axis, is this avaliable in this version?
Yes, this works. You can simple turn it on or off as i remember.

As i am quite busy now, can we just not hack lcnc to run a axis and run blending for xyz?
