Bonjour,
Il est bien possible de configurer une broche asservie en vitesse avec une carte Mesa 7i96s en utilisant le codeur de broche comme retour de vitesse?
Merci

> downside to the ethercat is its ONLY ethercat. i wish it has pulse as well. would be more versatile.

That's right. Now I remember that this is what pushed me to choose the M version. It seemed to me at the time that the pulse/dir was the simplest method, so it was less risky for me (this machine was my first build), and I paid some extra to get another option for the future. Turns out that CanOpen does not seem to be a viable option with LinuxCNC, but well...

If EtherCAT works well, wouldn't it make the pulse option look rather outdated ?

(Still need to do a lot of reading before I can consider an upgrade to EtherCat)

Good evening,

G96 constant surface speed on my lathe works fine with CW spindle movement. Now I want to use an upside down parting tool with CCW spindle rotation.

But the x-axis does not move. It works with M3 instead M4. Gmoccapy shows correct -350 rpm (minus!) during M4. I assume, that feed does not start because it waits for positive spindle speed.

Do I realy have to use a separate HAL file with negated spindle feedback?

Best regards,

Hartmut
