Hi.

Thank you for your reply.

The reason that I want to use an axis for controlling the tool-carousel is that I am retrofitting an existing machine and the axes are already wired and ready to go.

I have just started remapping the M6-command, but there are so many things about this that I don't understand and I haven't found a source that explains remapping in simple words and in a more step-by-step manner. I understand that almost every machine is different and that it is almost impossible to make a setup-description that fits every machine. But I miss a document that breaks the remap-topic a bit more into easily understandable bits.

I have read some of the LinuxCNC documentation on remapping, and although this is very good I am almost left with more questions than when I started because of the complexity.

you might also want to have a look at the 'timedelay' component:

Hi Bari.

May I ask if you've ever found a good alternative for the Heidenhain EXE converters??
You needed a lot as you wrote... I presume you didn't buy 50 EXE's....

I need 4, with preferably an 10x of 25x interpolation..

Kind regards, Joseph

Seems my installation is already on the newest libc6 version:

Hi,

The spline fillets are working. These are used when clothoid fillet fails.

Tested multiple G64 P.. inputs along a gcode file.

The first square is original a G64 P0 with sharp edges.
The first G64 P5 creates ~5mm fillets along the path of the square shape.

Then the second square, the P20 creates ~20mm fillets along path of the second square shape.

The fillets are of type clothoid. Then there are rapid clothoids and feed clothoids, This is important to notice
to do look ahead and optimize speeds further on.

First get familiar with the estop-latch component. Chain 2 together. One for the estop button and another for this component.
Then you could try a time delay component.

I that does not work out, write your own component that monitors the fault pin. When it changes state, set a flag (maybe call it error_set) then in another variable (error_time) accumulate the time its on for
if (error_set){
  error_time += fperiod;
  if (error_time > error_delay) 
    do something
  }
}

Hey,elovalvo,I've installed your image in my rasppi5 machine,but met a problem while I installed the linuxcnc-ethercat ,I cant run "sudo apt install -y linux-headers-$(uname -r) ethercat-master linuxcnc-ethercat",because I cant find the right kernel version of header,could you offered that ? Thank you

Hello folks. I have a pin in a hal component. This pin becomes True when a fault detected. I wanna make e-stop if this pin remains True for a period of time. The key thing is time here. Because when machine goes e-stop off state after estop-on state, the pin remains True for a while, but it is not a fault signal. It is only reset state of the device. After some time, it goes to False and starts to operation. If i evaulate this pin without any operation, i am not being able to make estop-off, because the signal is being True at that time, and machine is doing estop again.

According to this scenario, i need a hal component which gives True output if the input pin remains True for a period of time. I've used oneshot-edge components but they don't meet my demands. They act like when input pin gives the expected edge, they give output regardless of time of input pin. If there is no appropriate component in LinuxCNC, i am gonna develop intermediate hal component to do it. If you have a solution, plase share it with me. Thanks.

if the joints were cables wrapped around a drum, would it still be appropriate to transform cable length the cartesian coordinates

Yes, as long as the cable gets wound up uniformly (ie the coil does not change diameter due to stacking of the cable on the drum).

or would you actually resolve that back to stepper motor steps in order to define a cable length?

This is done in the [JOINT_n] section of the ini file. The 'STEP_SCALE' value defines how many steps the motor needs to rotate to move the joint one machine unit (inch/mm).

grblhal is a good model for how remora is now, across multi framework.
Im mainly trying to do the mbed ce because it has better G0/H7 support (nobody making F4 boards) , but it supports everything that has remora firmware. its not as easy to setup as mbed was, but its easier than cubeide. Eithwer way, I can figure out this DMAMUX on the new stm chips, and mbed ce has an SPI DMA api, so I thought I would give it a try

But its not as if Mbed is dead, just Arms support/development of mbed. the CMSIS RTOS is still there, as well as the new community fork. the part that is gone is the tidy easy to use prepackaged mbed.

The error occurs after a tool change.

It looks like the z-axis is now jumping out of the machine area.

Yes, I need to look into this some more. I'm not sure where / how things got broken as we've confirmed that the NVMPG firmware has not changed in recent shipments.

This topic came up nearly 2 years ago when I started to look at the STM32H7.

forum.linuxcnc.org/18-computer/42276-rem...spi?start=590#252207

Something that we'll need address at some point and some learning curve as Mbed does make things simple to have a code base for multiple targets. The use of submodules was suggested but I never really got deep into understanding how we could re-structure things. 

Thanks! that has fixed it

I now have a little nano board communicating with HAL both inputs and outputs. So I just need to port the communication code from the nano test board into my ARM project and rejig the messages a bit and with a touch of luck I should have bidirectional data flow from HAL to my board. Hopefully the .py script is easy on the Linux overhead.
 

ArduinoConnector has major issues that the author does not seem to want to fix as they've been working on a V2 branch. The last commit was my friend fixing a bug I found before I dropped it. I wasted alot of time with ArduinoConnector, I made 2 custom PCBs around it just to realize it had so much lag it was unuseable (see my git issue).

Maybe version 2 will be better, but the main branch can't handle an MPG. You will wait literally 10 seconds for it to count the pulses and relay them back to LinuxCNC. All the lag comes from the Python side, the MCU side is fine. It's a great idea, with some great features. Unfortunately it's currently unusable unless you just want to push a couple of buttons.
