Is someone using Gmoccapy Plasma ?

what about this:

thcud.z-pos-in float in : Z Motor Position Command in from axis.n.motor-pos-cmd
thcud.z-pos-out float out :Z Motor Position Command Out
thcud.z-fb-out float out : Z Position Feedback to Axis
thcud.cur-offset float out : The Current Offset

do i need to do something with this pins?

cause right now i have done nothing with it

EDIT: Touch Off is working now with the PPC LinuxCNC THC, with little edition, thanks Marius

I am glad that you are getting it done. I assume that you connected the arc_ok and the up and down signals from the Proma to the parport and then to the THCUD component.
The up/down signals from the Proma will cause the Z axis to move up or down. The THCUD component captures the Z position command and drives the head up and down as required. The movement is not shown on the DRO as it would cause a following error. After the cut is finished, the THCUD component passes the control back to the machine.

sorry maybe i wrote false .. i only got the Z-Plane Touchoff running, not the THC

do i need to do something with the pins i wrote in the last post?


Maybe, if i get it running, we should update the WIKI that other users can do it easier

Did you read the man pages for the THCUD component?

I will be putting a complete setup on the wiki soon. Busy testing some things at the moment.

yes i read, but found nothing to grap. BUT in some other threads i found some more details. BigJohn wrote an simulation Program to test the THC and now im checking with the commands in there. maybe i can use something.

Z is now passed through and the component shows me the actual Z Value, but still not correcting it. But i think i´m on the right way

Remember that you will not see the correction on the DRO. The Z change is done only in the THCUD component. As far as the controller is concerned the Z never moves during a cut. There is a pin called thcud.cur-offset that when connected to the plasma.hal-lbl-corr it will show you the actual units of correction from the original position. The label is situated in the control panel in the plasma screen.
