Hi George,

I haven't yet had a chance to try a configuration like one Wayne described (and Giles helped me understand). Hopefully I will have time this week to give it a try.

The behavior you describe for the DMOV and MOVN does sound like an issue that needs to be addressed.

Are you also using a Delta Tau Power Brick (or some other Power PMAC model) controller as I am?

Regarding your Tech-Talk subscription: I would expect that once you are subscribed, you should be able to include the Tech-Talk list email in your To or Reply-To list (we will see momentarily, as I included it in the To list for this email).

Hello Davis!

I am George and I and @Luciano Carneiro Guedes are working with coordinated motion on a 2 motor slit controlled by PowerPMAC and integrated with EPICS (The same setup as you).

I saw your message on EPICS techtalk and I would like to know you if your setup is running well.

Here we achieved the point that we can drive a virtual motor using motor record as Wayne Lewis sad. The problem is that the DMOV (or MOVN) is not set to 1 (not moving) when all motors reach the setpoint specified by the kinematics.

I could not reply the message on techtalk because I subscribed on it after you send those messages (and I don’t know if it is possible to reply now…)
