BOXFORD 125 TLC Tool Changer Setup

Really? They design these things to annoy me, I am sure.

The quick and dirty way might be a timedelay component on the position sensor input.

Or, perhaps, moving the sensor, fractionally.

now implemented via timedelay, but additional forward rotation time may be taken into account in future updates

net toolch-01 => timedelay.3.in to_pci.1.pins.pin-16-in
net toolch-01a => carousel.0.sense-0 timedelay.3.out
net toolch-02 => timedelay.4.in to_pci.1.pins.pin-17-in
net toolch-02a => carousel.0.sense-1 timedelay.4.out
...
setp timedelay.3.on-delay 0.15
setp timedelay.3.off-delay 0
setp timedelay.4.on-delay 0.15
setp timedelay.4.off-delay 0

Be aware that there might be problems (over counts of tool position) if it overshoots off of the sensor.

I am trying to work out a fix for a similar but different toolpost that drops off the sensor on the reverse move, and so sees an extra increment on the next move.

The component started, but there are a number of wishes:
1.input of the timer, after which the component will generate an error if it failed to receive the carousel.0.ready signal
2.the output ERROR of the signal is an error from the previous point (now if, for example, an instrument disk jam or a similar component waits forever)
3. my tool has a tool disk landing sensor, I would like to see a separate input. Now implemented through and2 carousel.0.ready and sensor
4. carousel.N.jog-fwd rotates the dial, but does not enable reverse rotation for landing - a useless function, I think with carousel.N.rev-pulse> 0 should reverse automatically
5. the delay after the sensors are triggered, written in the previous message

If you manage to realize these wishes, the component will become even more versatile and applicable.

The "strobe" input might do what you want there. Or maybe not, it rather depends on the timings.

I think that this will work, but you need a non-zero hold-dc
github.com/LinuxCNC/linuxcnc/blob/master...s/carousel.comp#L324

Need to reinstall carousel.comp from link? I have the latest update
Or just add to HAL setp carousel.0.hold-dc 1
If so, it doesn't help
