Frankly, I'm a bit puzzled where that 5-10x safety factor recommendation comes from. A quick google search shows me 1.25x and 1.5x safety factor recommendations. I tend to go for a 1.5x safety factor, in more extreme duty conditions I've done 2x or 3x. A big contactor killer is frequent start/stops. I can imagine 10x might be used in some special applications.

The 7I76EU is compatible with 7I76E hal/ini files, so you can
just select "7I76E" in pncconf.

If you have usb, you can update with Deb files

Run another update i think your on the faulty commit. Should be resolved now, stable is now 0.6.5

Does this value always needs to be equal to the min value? Please help, thanks.

Hello. 
I'm new in this form. I couldn't config my Mesa Card 7i76EU, the PncConf doesn't show the 7i76eu. I'm using Linux CNC 2.9.8. Thanks in advance.

The two 120v ins is more just because I think I will overload a single 120v outlet so trying to split the loads to different circuits. It SHOULDNT but really dont want to wire this whole thing and THEN find out. This is unfortunately a "mobile" setup that I have to load up and take to and from work as I cannot run a router like this in my apartment so I am also making some allowances for portability in this setup so both plugs will be detachable from the unit to ensure power safe if needing to work inside the box. All of this is going in a rolling road case... Yes I know sketchy sketchy sketchy but.... nah no buts I know its sketchy.

I know that some contactors are mechanical so going higher amps increases service life and solid state contactors are heat limited but why would companies state that such a high overage is needed?

I will have YangYang take a look after the holidays, thank you for testing.
We are on a Chinese new year brake for a couple of weeks.
I'm still working on Planner Type 2, will see what YangYang thinks after the holidays, hopefully Rob will also do some testing

Most contactors list a thermal current rating and an inductive current rating, if your load is less than those current ratings you're fine.
I usually use 30A contactors for 20A loads... just oversizing a bit for good measure.

Not sure about two power sources, are both going to the same box? I try to avoid that. It can cause accidents if someone disconnects one power source and starts working on it. If two power sources to one box is unavoidable, label the cover with a warning label stating the box is powered by more than one power source.

If the two 110V power inputs shown are going to separate boxes, I think it should be fine.
 

You maybe could check the lathe macros uo files using editvcp and fine the lathe macros in the probe basic widgets directory and verify the parsee widhet entry names correspond correctly with the macros being used. From a glance it appears they may not be the same.

You need to make sure those variables are get ng from the ui to the subroutine at the top.

There is no need for a GUI to get involved with external hardware. Thats what halui is for.
When GUIs extendRod their scope, we get a mess with differing configs for no reason.

Rod, I use the Axis GUI as representing what the hardware controls on my Three axis mill have done and are doing. In particular when setting the tool offsets using the touch off gui buttons, If the X or Y axis instead of the z is selected, then the tool table gains an unexpected x or y offset. If you control the machine by the gui that's my lookout, but to move a big machine around you must use a pendant. I have mpg and three momentary buttons to select the axis for the mpg to drive. It is very easy for me to move the machine only with the pendant, and lastly touch down the z direction for work and tool touch off with the x still selected because my jog buttons are not reflected in the gui. Done it too many times.
But, today, I found the forum.linuxcnc.org/38-general-linuxcnc-q...ns/50151-axis-select  python script, and its transforming. The radio buttons move with the last jog axis selected, and I can stop worrying quite so much about stray tool table entries.

Sorry for not responding but Ive been trying other distributions (Mint, Ubuntu, and some wonky 3rd one I cant remember) hoping for better results and all end in either failed installs or crappy results.

I have another pc im hoping to try but havent gotten to it yet. Ill try the clock correction thing tomorrow and see if that yields anything better.

Good Evening All,

I am building an electronics enclosure for my CNC router project and need some education on relays/contactors.  I have a couple salvaged components from an industrial bandsaw that I am integrating such as safety relays, e-stops, buttons, terminal blocks, and maybe contactors…  I preface all the below with I don’t know much about how electrical components work so PLEASE point out even something basic that I might have gotten wrong because I honestly do not know.

The very basic question of this is how do you size relays/contactors for inductive loads such as Makita RT0701C and 48vdc power supplies to run the steppers?  I will be running two separate circuits but if I hit the e-stop I want to cut power to these components while leaving other things like PC, Mesa card, fans, and the e-stop system itself powered.

* Circuit 1 - Makita – 6.5 amp 120vac in
* Circuit 2 - 2x 48vdc PSUs 5amp 120vac in (6amp 3sec surge)

My research says you have to go 5-10x the load when sizing relays/contactors but does that mean I would need a 120amp contactor for my steppers that are a 10 amp regular load?!  the 10x number was more related to solid state relays but this just seems nuts.

I found a McMaster-Carr table that shows a 1.5 hp motor drawing 20amps at full load (Makita claims 1.25) and I would need up to a 200 amp contactor?!  www.mcmaster.com/7603KAC/


As stated electricity and I are not the best of friends so we avoid each other as much as possible.  I could be (and hope I am) missing something very basic here.

Components I have:
* Idec SJ2S-07LW 8amp icecube type relays – 24vdc coil draws 0.025 amp when closed
* Mitsubishi S-T10 Contactors – 24vdc coil draws a MASSIVE 1.3amps when closed (not sure I want or even CAN use these also WHY would this draw so much?)
* TWTADE/JQX-62F-2Z 80 amp contactor - 24vdc coil draws 0.088 amp when closed
* LCTC Solid State Relay 80amp – Its in the mail but don’t know if its any good.

The below is the basic plan I have for wiring power.  If anything in this looks wonky let me know as well please

New PR from YangYang is ready, hopefully will be merged soon in master

This adds ruckig in the planner type 1
if you want to test it get the binary from

github.com/LinuxCNC/linuxcnc/actions/runs/21975584400

or build source from my repo

github.com/grandixximo/linuxcnc

Testers are welcome to report here or in github, thanks!
 
Hello gentlemen,

movement are incredible smooth ... basic shaping what I have tested till now is pretty ... but during movement at more points during simulation of rotation interpolation its jumping or woobing ... kind off braking and next accelleration 

most spiking during cloud of points are gone ... some spiking are still present but it a huuuuge step forward 

testing setup 2ms benchtop profibus master 3axis geany gui ... 3 servo axis with synchronized speed control loop at 2ms

some testing fault popups triggered during the movement of file 3_1001.ngc

I am still testing at default simulation file from past but splitted to separated operations ..

thanks a lot for your progress ... I am watching it every single day with mount open and box of popcorn to reading the edits ... 

regards E.
 

I have noticed the slowing during the round movement too but I forgot to noticed it here.... yes it is present and its present during 100% feed value ...

crashes are not present during the 100% feed just if its not 100% ... 

crash log is in the attachement if somebody are interested ...
