a little tweak of FF1 to center the ferror
during cruise is probably in order
(average looks about 1/4 of a division low during cruise)

After that, looks like some 'I' would pull in the slow ramps
of ferror during accel and deccel
(and get rid of the static ferror at the beginning)

Thanks pcw if found after some reading and testing that my drives don't respond around 0.15 etherside of zero would you think the inverse deadband comp should work?

i have tryed some i and every time i try usless im not trying small enough numbers it throws the whole ferror off constant and all so what would help i read in another post about ff3 maybe ill post another chart tommorrow when i get chance to get back of the machine the ferror is closer now tho

hi again everyone im having problems trying to link the input status of the mesa cards inputs to my pyvcp panel all i want is to show arc on and arc transfer if i try to link the d-in or d-out signals in my postgui.hal file i get the error that this is already linked and the same if i link direct to the mesa pins ie in the postgui file if i use hm2_5i20.0.gpio.034.in it will complain the same ive even tryed using the mesa input direct in the xml of the pyvcp panel but still it doesnt work

i know this will be something simple but i cannot bottom this

many thanks john

The first thing you want to read is

linuxcnc.org/docs/html/hal/basic_hal.html

You can see in the net diagram how you can have more than one reader of a signal. So to "connect" an second reader to a signal do something like this:

hi john still having issues with this ive gotten round the arc ok input buy linking that to the inversion of the gpio (the in_not pin)

as i had issues with the pin not exsisting and such or that the pin was already linked to another

but with the the led showing an output status i cannot do the same and cannot get it to work without error on starting axis
