Check the last say 10-20 lines of the output of "sudo dmesg".The ethercat master
always tells why (in a not so obvious way) why slaves won't go OP.

hello guys
i really need help with configuring R3EC IO coupler + R3 1600 DI + R3 0016-P DO ,to my etherCAT system,
i wrote XML file but when i check the status of the slaves all the drivers are in OP mode except the R3EC is in SAFEOP and it does not switch to OP mode,
here is the XML section for the R3EC i used : 
<slave idx="6" type="generic" vid="0x00004321" pid="0x61400025" configPdos="true">

i appreciate your help guys i have been stuck with this problem since two weeks!

Ohh thats very good to know! Probably stick around with the "dumb" devices then. But any other experience is welcome!

  Hi Everyone, first post here on the forum.I'm very new to Linuxcnc, and am building a 4 axis machine. I have Linuxcnc 2.9.3 installed and literally just a few days ago started playing around with jogging in increments within Qtdragon_hd. (love the interface)Sadly the only increments that actually work are 0.1mm or smaller. Everything else produces random results.After some reading it was suggested that I update the qtdragon_hd handler.py which seemed logical, and after downloading from the github a new .py file (95.5kb) I eventually figured out how to replace the original.Unfortunately now I cant launch the program and just get an error - hopefully attached is the report. If I revert to the original handler.py the program launches but I still have the unreliable increments.Have I missed a link somehow with respect to the new handler looking for a reference to my HAL and ini files?Would love to get some input for a solution.Many thanks

I dont have the 556 but i have the 542j which seems similar to one of those. In the sense that it has the serial port and 5v/24v switch. I noticed that this drive has some kind of internal processing that causes a following error. At any speed the motor lags the pulses and more so as speed increases. At 2500rpm the motor lags 1/4 turn behind the pulses, which makes it a poor candidate for use with encoders, and probably causes poor interpolation. I tried tweaking the settings with the leadahine software but no luck... ended up switching out with geckodrives and now have zero following error.

I was having this conversation with an engineer friend and he also noticed that some leadshine drives have a mind of their own.

Hi everybody,
since I am planning to update a Wabeco CC-F1210 with something quite up to date hardware I saw the DM556 and thought those would fit quite good. But there are so many "versions" of that thing.
Probably the most differences are in the following 2 models:
www.omc-stepperonline.com/digital-steppe...stepper-motor-dm556t
and the leadshine version:
www.omc-stepperonline.com/leadshine-digi...-stepper-motor-dm556
Is the new functionaliy of the leadshine worth the buck? Does anyone has real experience with both?
regards Han

Thank you all!

Hello, I'm a beginner in Probe Basic UI and want to add some machine specific buttons in the USER section of the UI screen.
I understand that the layout is designed by using Qt Designer but have no glue whow to link/connect the button with the hal pin or signal of the machine.
Any advise ot link to a helpful YT video is apreciated. I could not find a YT tutorial or step-by-step guide/documentation.

I've been distracted by configuring a CAM post for this machine, and kind of blown away, that after months of learning, I can decide on a strategy, select tools speeds feed etc, and output the NC code from the CAM system and linuxcnc, parses it without comment. Not only that the machine runs the code and the the part is to drawing. Just excellent.

The orient.svg chart, while I get some of what it is telling me, i cannot understand how I need to convert it into hal statements. I thought by now I would get this stuff but I don't. which ones are loadrt, addf, setp and net ?

Sorry to be a dunce.

Could I ask for some pointers please?

Thank you very much

It's the xy allowance 0.25mm , using a 6mm tool machining 6.05

Hello,
i just started with SolidCAM and try my first job -> attached photos..
All working toolpathes are blackish and one not working toolpath is blueish. Here i want a 6.05mm hole/4mm deep. Tool should be a 6mm end mill.
Tried many things but still don´t work.

Please help

..AND, I see now, Mesa page says 7i84 is obsolite, there is the 7i84U now..


AND differences are: 
1. Field outputs can be set to sourcing, sinking, or push pull modes on a per output basis.
2. Field outputs do not require flyback diodes for inductive loads regardless of load current.
3. 500 mA output current

So, nice!

Thanks! 


 

Thank you Tommylight,
looking at the 7i84 specs pdf, it seams the easiest solution.

Inputs and outputs works from 5V to 28V so it's ok (and yes you're right about the half/half voltage, as stated in the pdf).

There are two version of this board:

sourcing outputs: (7I84)
or sinking outputs: (7I84D)

I will use inputs only for now, but... I have to decide which one is better for any possible future expansion...

Any ideas? Better sourcing or a sinking outputs?

(Post Scriptum: probably Sourcing is better?)

Thanks

I also cover RT tuning in this video


What's not immediately clear that the servo thread and base thread are the only RT components used by Linuxcnc so that is why you only see one core in use.
