Re: [Emc-users] Linuxcnc and Arduino

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

Re: [Emc-users] Linuxcnc and Arduino

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

I have a XHC - HB04 Wireless MPG during LinuxCNC HAL module. If I turn the crank too fast I have a time delay ??? It's dangerous 2016-05-17 11:21 GMT+02:00 Forum Deswysen : > Hi Andy, > > With a python script and the serial port : > >

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

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

Re: [Emc-users] Awlsim, raspi-profibus

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

Re: [Emc-users] Awlsim, raspi-profibus

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

Re: [Emc-users] Awlsim, raspi-profibus

I agree. Being able to use Profibus with LinuxCNC would be very useful. There is a lot of used Profibus slave I/O devices and VFDs on the surplus market. Dave On 5/17/2016 4:02 PM, Nicklas Karlsson wrote: > Authur of pyprofibus used an ET200S module. > > I tried pyprofibus with RS485 and an

Re: [Emc-users] Linuxcnc and Arduino

is it windup? like a queue is filled up with commands and has to drain? yes, handwheels should stop when you stop turning, not later i saw it on pmacs, the fix was something like the charge-pump used on linuxcnc the rotary pulses allowed the action(similar to charge-pump), and ending rotation
