Sorry for disturb,i have an problem with my nvem board,is same as board on this topic,im write here but im undestand we are expert on pcb .....when im power on the grren led blink at 10% of light and speed,the item on pcbU7 "DE=G12" is hot and ,the led "D15" blink when insert a cable,the situation of led not change and switch or pc not blink he light.
we have any idea for solve my situation ??
sorry for disturb

Maybe i was not "tactful" enough:
-no need to be sorry at all
-i was trying to give you a push to move forward
-when you start wiring stuff it will be stressful, but when you see things move you will be very happy
-when you see the machine actually working, oh what a joy !

I got my touchscreen monitor delivered yesterday and just wanted to confirm that the issue I was having with touchscreen button not working right was a consequence of using Flex GUI in a virtual machine on windows. The Flex GUI that I made works perfectly on a real machine with touchscreen. For the real machine I am using a RPi 4b and a generic 10" touchscreen monitor.

For anyone else designing their GUI this way, I am using VirtualBox on a Windows 10 machine. The virtual Machine has LinuxCNC 2.9.4 installed from the live iso download. Here are the couple quirks I have found running it in the virtual machine. I want to stress that these issues don't exist once the .ui file is put on my RPi machine.

1. touchscreen buttons don't respond as expected in virtual machine
2. The machine will unexpectedly go to "Power Off" as soon as a motion command (Jog, MDI, or in a program) completes. Doesn't do it every time, but pretty often. Again, only in the virtual machine.
   
   I also want to again give thanks for this wonderful tool and to give a peek at what I am working on. I have a 3 axis benchtop mill (RF-45 size) that I converted to CNC a few years ago. I did this as a hobby and use the machine for my hobbies. It has been run with many things including LinuxCNC on an old tower PC with ancient monitor, keyboard and mouse, with GRBL on an Arduino hooked to a Netbook with my own Visual Basic interface, and I tried one of those standalone controllers, but sent it back because it was junk. I finally decided to just do it better and got a RPi 4b, installed LinuxCNC and have been working on an interface that for most of the way I use the mill can be done without ever touching a keyboard. I'll still have a small wireless keyboard with trackpad available if needed though. This is the interface I'm working on and I think it will suit me. I have the UI sized to perfectly fit the display that I bought to use as much space as possible. Thanks again for the very useful tool.

The spindle is off:

bit FALSE pdnt.spindle.is-on ==> hm2_7i76e.0.7i76.0.0.spinena
 

Start wiring stuff, make things move, stop worrying to much.
I do not recall the exact amperage, but i do recall it was more than enough for what you need.

Can you find a FBUC?
If you call Elumatec or FerroControl, make sure you are sitting when they tell you the price. I was asked 27000 Euro for the old PC!
Check the drive manuals if they can use something else for control, and if they do output encoder pulses, that would make things much easier.

ok,

lets write it in here so any newbie can see, correct me if i am wrong;

- there is a folder /usr/share/qtvcp/screens/tester that folder has the sample .ui and .py file
- and there is a folder /home/<username>/linuxcnc/configs, u have to create a folder named tester in there and put tester.ini, tester.ui and tester_handler.py files in it

if u dont put tester.ini file in that folder, u can not see tester under My Configurations during linuxcnc launch.

when u put a tester.ini file "tester" can be seen during linuxcnc launch so that u can select it and load.

but i dont have a correct .ini file so linuxcnc gives errors during launch and exits.

question:

by using linuxcnc Pncconf wizard(i am gonna use mesa card) can i create the .ini file?

so in its display section if i enter "tester" does it load the tester.ui i created in qt designer?

most probably yes am i correct?

Hi Chris,

Thanks for the Lathe GUI. I've tried to set it up using 2.10 but ran into a few issues.  I did my setup for my lathe in pncconfig selecting QTDragon as a gui.  After I've completed the setup I changed the DISPLAY setting in the .ini file to qtvcp -d qtdragon_lathe.  Is this the correct way or is there another way to setup qtdragon_lathe?  I'll elaborate on the issues if my attempt was correct. 

I've modified a manual mini lathe to cnc to test some lathe features and would gladly assist with practical issues with the development of qt_lathe.

Well, I'm not in the position to tell you what you can or cannot do but your first problem is that you have to find out what kind of fieldbus is used. 'ferrocontrol CNC fieldbus' can mean anything. It might be CANOpen or something entirely proprietary. The only one that is reasonably well supported in LinuxCNC is EtherCAT which is not what your drivers use. I think there has been somebody here who got a CAN bus working through an EtherCAT interface.
In my opinion your best option is to get new drives and motors (preferably step/dir or if you feel like it Analog or EtherCAT). The costs of this can be calculated reasonably well and integration in LinuxCNC is well supported.
Everything else is certain to involve a massive amoint of time that is quite likely to lead you nowhere.

Thank you @Hakan! Is there a place in documentation that this can be referenced? I have found a few manuals like getting started and the ones listed at: linuxcnc.org/docs/stable/pdf/ but this command did not seem to be mentioned.

Thanks again,

Steve Cap

If you can measure the temperature of your transformer, put a load, and check the temperature. As Tommy said, that's the unique concern. So, until 60°C, you are fine. Insulation can go above, but I'm not sure what would be safe for the insulation. I think I drove motors until 80°C, maybe 100°C, without damage but it's not a good idea at all, you will heat the cabinet and can hurt someone if touching it.

The sticker may be gone... It although may be printed on the side.

First of all thank u for your reply,

i loaded and checked some demos which came with linuxcnc, the thing i want to achieve is as same as qtplasmac_p_metric which is a 9:16 vertical design, its too bad that it is for a plasma, i need a cnc 4 axis mill version of it.

i know in general that .ini file declares the name of the .ui file and i dont know why but u guys make the general layout in qt and then style it with .qss file, qt is there for ui design is it not possible to create all ui with images or qt elements directly in qt? i mean is there some kind of limitation in qt for linuxcnc that u guys prefer to use coding for ui styling?

anyhow this is what i was looking for;

- create an .ini file which includes the following base code in it(a sample base code can be given) or copy one of the .ini files from demo screens,
- rename the screen name
- put it in a folder named tester under..... location together with the .ui file
- and copy tester.py from .... location .... to the same folder
- run linuxcnc and tester will appear under sample configurations/sim(i dont know if u put all in a single folder it will appear in there or not)

because if u dont say where to put and how to create all the necessary files in the document then its not a document its just general information thing.

I still dont know how to create(what to put in) .ini and where to put .ini and .ui file for linuxcnc to see them so that i can choose that ui.

Which folder is it?

and should i run any command for linuxcnc to load it at the first time?

Think about adding 2 resistors in series so that if one fails, the other one can still handle the voltage and power dissipation.
What I mean is to consider the risk that if R7 breaks into a short, you have the full DC going to the pcb. I would also suggest using "pulse-withstanding" resistors that are also flame proof, example something like this S5-47KF1 (yes expensive) but at least flame proof and "safety" SMF347KJT.

I think the differential approach is good vs a single ended. You might want to think about filtering the analog signal (differential and common mode), datasheet recommends LPF 10x sample rate.

Just my 2cents, if someone has better ideas or corrections I'm always happy to learn new things.
