I have updated my plasma table with a chinese ttl laser and follow your threats about M67 so i copy paste and ajust my hal with these lines:
loadrt pwmgen output_type=0
addf pwmgen.make-pulses base-thread
addf pwmgen.update servo-thread
setp pwmgen.0.enable TRUE
net analogout motion.analog-out-00 => pwmgen.0.value
net laserpwm pwmgen.0.pwm => parport.0.pin-02-out
I don´t know how but now if i open linuxcnc and simple load file to raster engrave a image the laser doesn´t turn on.
If i set S command to for example S65, then load file and all runs well being the laser in a range of 0 to 65.
During this the S values are not updated but the result is like should be.
What could i do wrong? can you or anybody help?
thank you in advance
Threats ??? Oh, threads!
Do you have a running base period or base thread?
Are you actually using a parallel port?
Is the port loaded?
Or just upload the hal and ini files here so we can have a look.
Hi again Tom
Base period or base thread? i simply don´t know, sorry.
Yes i'm using parallel port and loaded
After messing around, i return to a point now that laser don´t stop between movements, in one point i was almost there but then didn´t backup hal file....
