I would not expect very smooth operation in 'D' or step motor mode (no
encoder
feedback/PID), especially with IGBTs and their long switching times that
neccessitate a large dead zone. Do you have the dead zone time set
properly? I
think the default is 5 Usec which is (deliberately) huge.
Hi people.
Reading this mail I discovered Rockhopper python interface feature that
honestly I have never heard before.
First of all it seems to be very useful.
It shows the hal file component connections graphically.
Is this feature available independently from Rockhopper python interface ?
I mean
I use an Automation Direct GS2 VFD on my Series 1 BP. LinuxCNC has a
component to control the GS2 via modbus.

You don't have to run Rockhopper all the time (which is the source of my
problem). You can just launch it from the command line and connect to it with
a web browser when you want to do a hal graph. If you launch Rockhopper after
Linuxcnc is running you will never see the error I have.

Works fine for me using a Toshiba VFD controlled from a Pico Systems setup.

Thanks Tom.
A graphical design of HAL components connections is anyway useful and I
think that many LinuxCNC users/integrators would like to have a reliable
tool for this.
I hope that this feature will be available soon :-)
But the Rockhopper is a nice discover for me.

Thanks Ed.
Go ahead please.
I know that list all the different components and modules and cards is a
massive job to do.
Your way seems to be very promising.

What do you mean by actual physical dead time - electric (which I
described earlier) or physical some..?
IGBTs have a large on voltage (maybe 2V or so) which will add to non
