Spindle Step/Dir servo ramp down before stop on M stop command.

Hello Andy, Nojo and all the linuxcnc community, I have a small question: is it possible to use your Axis C configuration with a simple lPT card, for my tests, use only the // port. I want to use MESA cards later on, but I would like to see how it works, if so, can you tell me more to pass the port // configuration, I'll keep you informed of my progress.my current configuration is: servo AASD 15 z (2.3 kw 12n) x (1kw 10n) spindle motor asynchronous 5.5kw with VDF ALTIVAR 31 + encoder 200 pts
attached, g -code for axis c, it is a test that worked with the examples of linuxcnc:

Sincerely [attachment

yes Andy, it is already the case when I simulate a thread with an encoder of 1024 pts, it is to make me a first idea, according to you, I should not exceed 200trs/mm? and what can I expect with a mesa card and an encoder of 1024pts,and a last question, (for the moment;-)) can I remain in version 2.7.14 or it is necessary to update to 2.8 for your configuration ?

Yes, that's what I thought, the Mesa are the top according to what I saw on the forum, tell me, can you confirm that I can stay in 2.7. 14 ? Thanks Andy

I don't think it makes sense to add an extra processor. LinuxCNC can do all that is required. See, for example, the sim config sim->axis->vismach->vmc-toolchange

Where do I find sim config sim->axis->vismach->vmc-toolchange? I don't find it on my installation..

In my current wiring from the base machine to the X axis/ATC location I have 10 wires with signal to the ATC, and 10 with signals from the ATC, all to/from the 7i76 MESA card, as well as various power supplies, etc, This would have to be sufficient to control/monitor the ATC and the small milling spindle. I guess the number of I/O should be sufficient, so I am going to follow your suggestion and leave it to LinuxCNC to manage..
I will go through your references and learn, hopefully.
The ATC hardware is still a few weeks away.

It shoiuld be in the config picker, under "sample configs".

Once you open it, a copy will be made in your linuxcnc/configs folder.

Thanks - found it - had to drill a little deeper..

Good evening to all, here is my problem:at the moment, I'm trying to configure an axis c for my lathe (for the moment chinese card; port //, then 5.25-7.76), the worry is that I can not install the component "axis c" of Andy (see photos)yet the component is installed,?, I use version 2 7.14 of linux (this is not a problem?) I confess that I am looking for a while. thank you in advance
