thanks andy

i open another thread because i search for a option to home via subroutine.

in the new thread i wrote about the subroutine i need...

i think this is the way i must use to get it work like mach3 the last 5 years..

the toolchanger is one of the last parts i need to do...


is it possible to home a axis with a subroutine then it should work...

Not really. It is possible to home with the built-in homing behaviour, and then do tool-changes with a subroutine though.

Do you have the boxford.comp working?

If so, try to merge this into your HAL.
loadrt sum2
addf sum2.0 servo-thread
net A-cmd joint.2.motor-pos-cmd joint.2.motor-pos-fb sum2.0.in0
net T-cmd toolchanger.position_cmd sum2.0.in1
net S-cmd sum2.0.out stepgen.2.position-cmd

That should leave the A-axis homing normally as part of the home sequence and still allow the component to control it for tool changes.

ok dont understand it.. but i will check it.

yes the boxford.comp works ...

the homing works.. but after the homing i need a defined fwd move and then a defined backward move to lock the turret to the pawl.. and this is where my problem is...

i want the 2 move after homeing automatic...

you understand me or?

if i home the turret the pawl is not in contact... if i change to tool2 3 4 5 6 all works but the pawl is not in contact.

to get the pawl in contact and lock i need 2 extra moves... thats all...

The boxford comp should do the moves?

By the way, I forgot:
net A-homed joint.2.homed toolchanger.ishomed

The rest as-documented in the toolchanger file.

not the homing move.. the homing is by clicking home a.

but the pawl is not locked... extra moves needed.. that why i ask if it possible to make a subroutine...

home,extra moves and set to tool1.

if i do this... :home a, jog to lock position, set tool 1 as active with g43...

then i can do toolchanges correct.
but this routine on one button.. like a pyvcp button... would be perfect.
