Its been a while since i did this, but I think you are close.

Some named parameters exist without the prolog code, look in the G-code parameters docs.

Ok m6 tx working perfect. Adding on z motion now.
How do I move the z soft limit on the fly?

I can't find the reference I saw before. On my phone in front of the machine googling. Haha.

while were on the swapping limits... swapping to servo spindle mode or the equivelant for orienting...

ive looked at the drawing, it makes sense I think, but how do I implement it?

Linuxcnc wont let me assign 2 axes to one output, so clearly that's not the way its done :P

thanks

I can't find which module they are documented in either. But I imagine you would use these pins:
Code:
Component Pins: Owner Type Dir Value Name 65 float IN 0 ini.0.backlash 65 float IN 0.05 ini.0.ferror 65 float IN 0 ini.0.home 65 float IN 0 ini.0.home_offset 65 s32 IN 1 ini.0.home_sequence 65 float IN 50 ini.0.max_acceleration 65 float IN 40 ini.0.max_limit 65 float IN 5 ini.0.max_velocity 65 float IN 0.01 ini.0.min_ferror 65 float IN -40 ini.0.min_limit 65 float IN 0 ini.1.backlash 65 float IN 0.05 ini.1.ferror 65 float IN 0 ini.1.home 65 float IN 0 ini.1.home_offset 65 s32 IN 1 ini.1.home_sequence 65 float IN 50 ini.1.max_acceleration 65 float IN 40 ini.1.max_limit 65 float IN 5 ini.1.max_velocity 65 float IN 0.01 ini.1.min_ferror 65 float IN -40 ini.1.min_limit 65 float IN 0 ini.2.backlash 65 float IN 0.05 ini.2.ferror 65 float IN 0 ini.2.home 65 float IN 1 ini.2.home_offset 65 s32 IN 0 ini.2.home_sequence 65 float IN 50 ini.2.max_acceleration 65 float IN 0.12 ini.2.max_limit 65 float IN 5 ini.2.max_velocity 65 float IN 0.01 ini.2.min_ferror 65 float IN -8 ini.2.min_limit 65 float IN 0 ini.a.max_acceleration 65 float IN 0 ini.a.max_limit 65 float IN 0 ini.a.max_velocity 65 float IN 0 ini.a.min_limit 65 float IN 0 ini.b.max_acceleration 65 float IN 0 ini.b.max_limit 65 float IN 0 ini.b.max_velocity 65 float IN 0 ini.b.min_limit 65 float IN 0 ini.c.max_acceleration 65 float IN 0 ini.c.max_limit 65 float IN 0 ini.c.max_velocity 65 float IN 0 ini.c.min_limit 65 bit IN TRUE ini.traj_arc_blend_enable 65 bit IN FALSE ini.traj_arc_blend_fallback_enable 65 float IN 4 ini.traj_arc_blend_gap_cycles 65 s32 IN 50 ini.traj_arc_blend_optimization_depth 65 float IN 100 ini.traj_arc_blend_ramp_freq 65 float IN 0.1 ini.traj_arc_blend_tangent_kink_ratio 65 float IN 1e+99 ini.traj_default_acceleration 65 float IN 5 ini.traj_default_velocity 65 float IN 1e+99 ini.traj_max_acceleration 65 float IN 5 ini.traj_max_velocity 65 float IN 0 ini.u.max_acceleration 65 float IN 0 ini.u.max_limit 65 float IN 0 ini.u.max_velocity 65 float IN 0 ini.u.min_limit 65 float IN 0 ini.v.max_acceleration 65 float IN 0 ini.v.max_limit 65 float IN 0 ini.v.max_velocity 65 float IN 0 ini.v.min_limit 65 float IN 0 ini.w.max_acceleration 65 float IN 0 ini.w.max_limit 65 float IN 0 ini.w.max_velocity 65 float IN 0 ini.w.min_limit 65 float IN 50 ini.x.max_acceleration 65 float IN 40 ini.x.max_limit 65 float IN 5 ini.x.max_velocity 65 float IN -40 ini.x.min_limit 65 float IN 50 ini.y.max_acceleration 65 float IN 40 ini.y.max_limit 65 float IN 5 ini.y.max_velocity 65 float IN -40 ini.y.min_limit 65 float IN 50 ini.z.max_acceleration 65 float IN 0.12 ini.z.max_limit 65 float IN 5 ini.z.max_velocity 65 float IN -8 ini.z.min_limit

O_o

now I'm just more confused, haha.

so,
ini.2.max_limit would be our z axis upper soft limit which we could change on the fly from the toolchange subroutine?
ini.z.max_limit is also there. odd.

while were at limits... when I home the machine, randomly, on any axis, it will occasionally give an f error. the machine is finding the switch, then the index. it always give the error when hitting the index.

any thoughts? at the speed its running, I cant see how it would be exceeding the f error, especially since it never does at any other speed.

is the per axis index_enable signal wired to the PID component?
If not this can cause a thump when index is detected

Also I've seen this when the thread order is wrong. Handling index detection is a bit tricky since the position
is zeroed when index _enable is true and the index is detected.

all I did was check use index in pncconf wizard. ill have to check the hal/ini to see what its actually done. there definitely seems to be a thump though.

Ok on the homing.

After setp stuff the next line is about using index.

Net x-index-enable <=> pid.x.index-enable

Should this move?

Now how am I dealing with the z limit. I don't see the pins andy wrote in there already. Where would I ad it and how do I use it? Thanks.
