emcoturn 120 / 220 tool turret hal outputs

then from a terminal, type halcmd -f then


setp hm2_7i76e.0.gpio.008.out true
setp hm2_7i76e.0.gpio.008.out false

the first section i dont get what to do with it.

but if i just do show param its true.

So does the state of DIR4 change when you do this?

hey, they are changing!!

i messure it with a volt meter between DR+ and DIR-.
with the other hand i did the command from true to false in terminal.

i dont have a 470ohm resistor on the pwm => ENA pin. i think its wise to add this i think.

So, some how the dir pins ain't getting triggered by the halfile, or it isn't set to it for the direction some how.

So you are saying the hm2_7i76e.0.gpio.008.out changes
(follow it with halmeter or watch) but the direction pins don't?
(as measured with a voltmeter)

i did:
while i was doing this, i measured between DIR+ and DIR- with a voltmeter.
The value was changing from +5v to -5v.

But, in linuxcnc at a toolchange command, T3 M6 for example, the same DIR outputs are not switching.

Right so you need to trace the signals

I did not make it clear but what I meant was to watch
hm2_7i76e.0.gpio.008.out while linuxcnc is running
and you request a toolchange then trace backwards
if hm2_7i76e.0.gpio.008.out does not change

ah i see.

i did this now. (il try to explain it)

hal file is as it should be. hm2_7i76e.0.gpio.008.out is connected to emcochanger.forward
i started linuxcnc, open halshow and watched emcochangerfoward and hm2_7i76e.0.gpio.008.out
request toolchange in mdi.
emcochangerfoward and hm2_7i76e.0.gpio.008.out are getting from false to true, and stays true.

Is the toolchanger connected?

There are many possible ways for this to not work (bad feedback, inverted feedback
signals relative to what the component expects etc,etc) , but one fairly obvious one
i mentioned before is the motor direction

Did you try swapping the DIR+ and DIR- leads?

yes it is connected.
motor is turning the ccw as it should do for a tool change. so thats good.

position is good. but, it its not really logic.
for example, if the next tool is just one position aways, it does a full turn +1

blue => opto 1 => Di 20
pink => opto2 => Di 21
yellow => opto 3 => Di 22
gray => opto 4 => Di 23

Did you try swapping the DIR+ and DIR- leads?

yes, then it goes the other way. so allso the in1 and in2 are working.


i insert the example file



this comp file is abit different then the comp file i use.
the one i use, has a delaystart and delaystart1, same for the delaydone
