If maximum speed is to low it take a while to catch up. I guess jog signal have 
to be limited to maximum speed.

Re: [Emc-users] Linuxcnc and Arduino

[Danny Miller]

I'm not sure what context you're saying you have for the XHC.

I have he XHC-HB04 on LinuxCNC  RT on the Linux RT kernel.

It's a VERY smooth response, but partly because my machine is very fast.

There is, however, a case for time delay if you select jogmode=normal 
and not =vnormal on a slower machine, or with greater scale on the 
handwheel.

Depends on the jogwheel speed vs the machine's acceleration and max 
velocity.  IF you set the wheel to its highest speed and spin it fast, 
you might command a router to move 50" in one quick twist of the hand 
that will take the machine 5 sec to execute.

This rarely comes up with me.  My machine is very fast and you have to 
spin the wheel unnaturally aggressively at top speed to get ahead of it, 
and it's not possible to get ahead by more than like 1 sec.

It cannot always keep the commanded position AND stop immediately when 
the handwheel stops.  That's logically impossible.

If you don't like that, you can select jogmode=vnormal and it will 
always stop when the handwheel stops.  However, you lose sync with the 
wheel.  e.g. quickly spin the wheel +2 turns forward and it may only 
register 1.5 turns before the wheel being stopped means the machine 
stops moving.  Then turn back -2 turns slowly and the machine is -0.5 
turns worth of motion from where it started, even though the handwheel 
is where it started.

I don't like this functionality myself.  And even that vnormal mode only 
means the gantry begins decelerating when you stop turning the 
handwheel.  If the machine takes 0.75 sec to come to stop from jog 
speed, it will not come to a stop until 0.75 sec after you stop the 
handwheel.

I recommend you reduce scale if you don't like it.  e.g. if you would 
never turn more than 2 turns/sec on that handwheel, and your machine's 
got a quick acceleration and 5 inches/sec jog speed, the scale should 
be  ~2.5 in/turn so you never outrun it.  With acceleration being 
significant, there's no definitive answer.

Re: [Emc-users] Linuxcnc and Arduino

[Todd Zuercher]

If the problem is that your able to turn the handwheel fast enough to exceed 
the maximum velocity for the axis and build up a store of pulses.  Perhaps you 
should consider limiting the step size generated by the handwheel to one small 
enough that it is not possible to easily over run the max velocity of the axis. 
 I have seen similar behavior even in large expensive commercial machines with 
Fanuc controls.  Granted you have to turn the wheel really fast, faster than 
you can sustain for a long enough period to build up a significant overrun but 
it is detectable.

 The raspi-profibus software is divided in two. The higher level is written

Authur of pyprofibus used an ET200S module.

I tried pyprofibus with RS485 and an Siemens ET 200L-SC, I get answer in first 
step but in second step for request diagnostic module does not send answer. I 
have several other profibus devices and they are very common but it is not top 
priority to get them working right now. In the long run I expect profibus to be 
a very useful part of linuxcnc since it is a very common protocol both for 
motor control and IO modules.

Observe the difference. raspi-profibus use a module with an AVR micro 
controller, pyprofibus use Linux.

I downloaded the Windows version of awlsim.

Its very impressive.Regarding the Profibus interface;   Are you 
using a RS232/ RS485 converter to connect to the Profibus I/O block?
Is the methods of configuring a Profibus drop documented some where?

I do Step7 programming but mostly in Lad/Ladder.I haven't tried it 
yet, but it appears that I could write a program in Step7, compile it 
and check it for errors and then export the source to your AWLSIM 
program and control Profibus I/O from a Raspberry PI, PC, etc !   Very 
nice!

What is your base-thread frequency? It may be that this is quantising
the output frequency.

When you began this thread you made no mention of wanting to change
the PWM frequency, and it is actually rather unusual to want to do so.
_why_ are you changing the PWM frequency? Normally you only change the
duty-cycle.

Re: [Emc-users] How to assign values to pwmgen parameters(duty-cycle, frequency, etc, ) from GUI ?

[adit bhargava]

Hello Andy,
I implemented your suggested code and I am getting correct values of Duty cycle 
on Halscope. 
However, I am NOT getting the correct values on CRO.On CRO, I get correct 
values for frequencies of  100 Hz and 150 Hz 
But, when I try 110 Hz , 120 Hz etc. it takes wrong period always as 10 ms 
(corresponding to 100 Hz only) and the T-on is also not 2 ms which I set in the 
scale.0.gain parameter (it's slightly more than 2 ms), 

However, on Halscope these parameters are correct.

Below is the code I did:


loadrt pwmgen output_type=0
loadrt tristate_float


setp pwmgen.0.enable TRUE

addf hm2_5i25.0.write_gpio base-thread
addf pwmgen.make-pulses base-thread
addf pwmgen.update     base-thread
addf tristate-float.0     servo-thread

net PWM-Freq tristate-float.0.in <= pyvcp.CO-frequency-value //frequency value 
from Axis Gui
setp tristate-float.0.enable TRUE
net PWM-OUT  tristate-float.0.out => pwmgen.0.pwm-freq



loadrt scale
net PWM-Freq scale.0.in // from above 
setp scale.0.gain 0.002
net duty-cycle scale.0.out pwmgen.0.value // Setting the Duty cycle
addf scale.0 base-thread //Added to base-thread   


setp hm2_5i25.0.gpio.023.is_output TRUE
setp hm2_5i25.0.gpio.023.invert_output FALSE
net pwm-generate    <=  pwmgen.0.pwm
net pwm-generate    => hm2_5i25.0.gpio.023.out

You should add it to the servo-thread really, there is no need to
update the value at base-thread speed.

That simplifies to DutyCycle = 2mS * frequency (which passes a units
check, but doesn't seem right)

You would use the HAL "scale" component:
http://linuxcnc.org/docs/2.7/html/man/man9/scale.9.html

(It is probably worth a skim through all the real-time components
listed in the section near the bottom of
http://linuxcnc.org/docs/2.7/html/ )

net PWM_freq scale.0.in
setp scale.0.gain 0.002
net dc scale.0.out pwmgen.0.value

Or similar.
