@Endian,

When you run the scurve in linux. The joint.[x].... hal outputs already show you position, velocity, acceleration that is
usable for your servo drive. The halscope shows a acceleration curve that is indeed not constant.

Yes it should be from there but it has that G64 P.. aproximation stuff and when I am not soo satisfied from it, it is better to use your TP with precise values of of it or?

This might help the noobs.
This video of mine explains how to build Linuxcnc for a RIP (and Debs)


Ethercat install is here  forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

But once you change the name, it should not matter if a user installed by the Debs. The .so just needs to be installed in the right folder. Perhaps that can be scripted too.

It will be interesting if your planner could be copied to the EMC folder src/emc/grotius_tp and the main  make file modified to build it.  I did this once for a seperate task module and it took about 15 minutes.
 
Easiest way is to grotius build an .iso file for greenhorns as me... but I think the best way to do it is to learn it myself but it is pain to everybody around included me who is something starting from scratch ... there it is a lot of stuff depends at a lot of other stuff ... I am starting them on my virtual machine but when it will work I will move to real iron .... I will need a little bit of help and patience too

Hi Endian,

Yeah. I know it's a pain.
But today i started building a new linux distro. I am at 50% now.
It will take some time.

Do you need additional software on the distro?

No basically not for me ... I am using only Geany, wine and lcnc + ethercat-master but others... If I am understand right what do you mean ... other stuff should be installed then
