Linuxcnc motion backwards (adaptive-feed negative value) and nothing happens

Hi Rodw,

I tested also gscreen. This is also good working with negative speed commands.
I will put it later on the git. i have already a account over there.

I think thats great. Anything to make it easier to use plasma machines in LinuxCNC has my full support (not that means much in the scheme of things). We need better support for plasma machines in Linuxcnc and until we have people like you who are manufacturers, progress is slow! If I can help, just ask!

I am also just starting to look into this adaptive feed with reverse. You seem to have it working now.

Which version of linuxcnc are you using now and which versions did you use to get this far?

I have found reverse-run-2.7, reverse-run-2.7-rebase, and reverse-master, reverse-master2 and reverse-master3.

It is a bit confusing and a lot of the work seems quite old (2015). Have you placed anything at github yet?

Hi Rudydp,

I am using the latest version of linuxcnc, you can find this with the synaptic package manager in your system file menu.
Search for example on the buildbot channel.

I have crossed this latest linuxcnc version with the reverse master 2. Here is the url for the reverse branche :
github.com/LinuxCNC/linuxcnc/tree/feature/reverse-run-master2 reverse run master on git

To compbine this 2 files was a very risky job, because you have to do 25 files. One file had 180 lines to be changed. So one digit mistake can mesh things up. But i had the time, and after all it works great !! It's a great function for plasma and tube cutter with 3 or more axis that have to go back to restart. So very important function for the future. Also for 6 axis robot's it's a very beautiful
function. You can go back with a reverse interpolation on 6 or more axis. That's wat it looks like.

Rudydp, you must compile my version of linux yourself, i have a little tekst document how to do that. Important is that you follow all the steps, because if you new with this, it can be very difficult.

I will look to place it on the git. Else i can make a download link for you.

For info : I have compiled the new adaptive feed version again yesterday. It compiles good. Also i compiled the latest linuxcnc version. They compile the same, so it's good.

Okey i made a download link and added a nice picture from the forum, nice high reselution pic anyway,
if you look good, you see the bitcoin's logo in the head cover of the pinguin :

You only have to registrate, after that you get the download link by mail.

I have the 2.8 reverse-run-master2 branch downloaded with git and have build it and it does give me adaptive feed after using M52 P1, but I do not get negative feed ie. 0 to -1, to work. Is there some other command required to get reverse feed?

I have also tried to register for your compiled version download, but have not made a payment (not easy without credit card), so I dont know whether I will receive the download link by e-mail.

@project update.

Rudy has downloaded the motion backwards from my website and installed it. On the 24 januari i get this mail :


I have already a github account but don't know how to upload the files over there. Someone can help?
So for clearity : this is the latest linux version combined with feature reverse run master, maybe we can put it in the master
branche.
