Hi, 

I am retro-fitting my 1968 Bridgeport Series 1 Papertape NC machine with rpi5/Mesa7i96s/Gecko203v.

I've got everything working pretty well it seems, except for the ESTOP.

I have (and want) an external/manual ESTOP-in button.  It is currently setup Normally Closed and appears to be successfully plumbed through to the GUI, which is to say that the GUI ESTOP button tracks the status of the hardware ESTOP-in button perfectly.

The issue is that my ESTOP-out is no-longer tracking either the GUI ESTOP or the hardware ESTOP-in.  It just stays asserted all the time with no change of state.

To be clear, before I attempted to plumb in the hardware ESTOP-in button, my GUI ESTOP was correctly plumbed through to my ESTOP-out so that it would allow me to disable the steppers.

Aside: I have not been able to find any documentation that really explains how ESTOP is expected to work?  I'm unclear on if I should work with estop_latch or not?  The estop_latch documentation is also pretty thin and does not appear to include any examples for either simple or complex configurations?

Here is my current configuration... (generated by pncconf)
Thanks,

B

I did not add the pins to post-gui.hal.  I was under the impression that qtpyvcp created the halpins outside of the user-config HAL process.

I see pins like qtpyvcp.probe-in and qtpyvcp.timerhours.in in the demo post-gui hal file but there is no loadrt or addf statements present.

I hadn't bothered trying to connect the new qtpyvcp pins until I could see them in halshow.  All the 'standard' probe basic or qtpyvcp pins are present in halshow... just not the new ones I'm trying to create.

I agree with Tommy, transformers don't often fail. At least not without a good reason. This is partly why Tommy was asking about the fusing/circuit breakers. They are there to protect things like the transformer. If someone replaced the correct size fuses with larger ones because the correct ones kept blowing, this can lead to killing the transformer due to overload. There is likely a significant problem somewhere that needs to be identified and corrected first before using a new transformer. Maybe one of the drives has failed, maybe there is a shorted wire somewhere, but something is causing too much current to be drawn.

Are you still looking for testers? I am at a position where I have some capacity to perform testing on this device with you.

I have a 1000w fiber laser running LinuxCNC that I use ~15 hours a week for the last 2 years. I am actively pushing the limits of my height control using the BCL-amp - mainly limited by detection range and sampling rate. Looking at your specs I think it would blow the BCL amp out of the water and lead to more capabilities.

I have a Raytools head BM110
 

Nice to see someone running LinuxCNC with a fiber laser machine! I hope you get a chance to try the C2V Laser Sense and provide your feedback. 

Also, if you're willing to share, I'd be curious to know more about your machine setup/axes, whether you're using galvos, controller choice, and especially, your LinuxCNC configuration. Perhaps in a dedicated thread, as there aren't too many posts on here about laser machines.

It seems to expect exclusively from a fixed list of video providers. Imgur is not one of them. Not sure if there is a generic way to embed a .mp4 video file on this forum.

opw do you have any messenger for real-time chat? Also, what times work best for you?"

Guten Tag,

Ich möchte eine Industrielle 5achs Fräsmaschine auf Linux CNC umrüsten. Das Ziel ist es eine zuverlässige und genaue Maschine. Der Umbau dient als Testversuch um später evtl unsere Produktionsmaschinen ebenfalls auf linuxcnc umzurüsten.
Die Maschine hat servos mit encodern verbaut, es können aber gerne neue Motortreiber verbaut werden.
Der grobe Plan bis jetzt ist: Mini PC mit Linux CNC, Motoren über ethercat ansteuern. 

Die Frage ist jetzt ob das gleich zuverlässig und schnell wie eine mesa karte ist, und welche Komponenten die ideale lösung sind.

Ich freue mich über Tipps!
 

HiI have a cheap stepper from Aliexpress EO42-EC. its open loop (can be selected wit dipswitch open/closed loop) for nema 42 steppers, maybe you need to tweak some things but they look quite similar. I attached the config here   

Nice work - that's kinda what I was hoping to achieve with my 2.8.4 install, but after hours of going around in circles CGPT eventually ran out of ideas and told me to install a newer version of LinuxCNC. So I went with the Python bridging app approach, which has actually turned out pretty good..! (A couple of screen-shots attached).

 

I may try and expand it to search each point (L/R/U or D) and trigger via a pin (I have the SeanD through tool Zprobe working on my machine) - will have to see what CGPT says about that...

Be aware that the same model laptops might not work due to variety of included hardware.

Hallo rodw,

the board is an Orange Pi 5 Plus without Wi-Fi.
kernel: Linux orangepi5-plus 6.12.0-rc7-edge-rockchip-rk3588 #5 SMP PREEMPT_RT
ethercat: IgH EtherCAT master 1.6.9 1.6.9-93-g4f9aa6f3
LINUXCNC - 2.10.0~pre1servo controller: 3 x Bosch-Rexroth HCS01.1EW0009-A-02-B-ET-CE-CE-L3

<master idx="0" appTimePeriod="1000000" syncToRefClock="true">
   The setting results in the described error.

<master idx="0" appTimePeriod="1000000" syncToRefClock="false">
   The setting results in the described error.

<master idx="0" appTimePeriod="1000000" refClockSyncCycles="1">
   With these settings, the function works as intended.

Hi,

currently I am buildung a new CNC machine. I set up a PC with LinuxCNC (new to the software) and Ethercat. I have 3 StepperOnline Servos connected and they work well with my basic configuration. For a 4th axis, i need a smaller stepper motor and I bought an EC1-57E Ethercat stepper driver like this one
de.aliexpress.com/item/1005012395271889.html 
With the command "ethercat slaves -v", I get some information about the device. I'm trying to insert the slave into my ethercat-conf.xml file, but I can't get it to work. Is there someone using the same stepper driver who can please send me an example XML file to use it? I'm trying hard to get it to work, but had no luck so far.
It would be really nice if you can help me somehow.
Thank you so much

Christian

Hello,
for space reasons, I would like to control my machine using a laptop and a Mesa 7I96 card. Is there perhaps a test program that can identify the laptop/PC's system components? Something like the Windows Device Manager, where you could disable unnecessary devices. You don't need a sound card, battery management, Bluetooth, etc., to control the machine.
Thanks
Hans

did you add the halpins to the postgui hal file?  you can use the blue led on the touch probe graphic as an example for wiring it up.
