how can i open it with supervisor, and edit it
i use Geany, 
im here :  cnc@debian:/usr/lib/python3/dist-packages/qtvcp$


 

I know of exactly 1 instance where drivers worked, on this forum. Plenty that did not work.
HP, Dell, Fujitsu, do not require a special cable/connector, but some HP will have a smaller header on board, not the standard IDC26. They do usually come with the port installed.
If applied over 5V, the built in parallel ports do not smoke and do not smell, that output remains high allways, that is with 12V. Never had an add on board go through this, so no idea how it ends up.
I like parallel ports

That is easy, just buy more Mesa boards !
PCW is the owner of Mesa.

Try this:
Find /usr/lib/python3/dist-packages/qtvcp/qt_pstat.py

change the relevant code to this:

Have a look at MPG files and pins, there should be something included with LinuxCNC and might have something useful as they do control those values.

well that i do :O , where to change the directory ?

Do you see touchoff_subprogram.py at:
/usr/lib/python3/dist-packages/qtvcp/lib/touchoff_subprogram.py

Was just looking at those. the reviews say they are horrible and not accurate. gotta sift through to see which one is worth buying.
tomorrow

Sorry I realise now why you are using Wheezy, it's the Sherline thing.
My apologies.

Regarding PCI or PCIe Parallel Port Cards.
1: Forget about manufacturers' supplied drivers. They all usually for old kernels, modern kernels have them just about all covered. And to tell the truth there is only a handful of chipsets used. Trying to build these drivers have sent many mad, it's not worth the effort or heartache it brings. Poking a stick in ones eye is more productive (and please don't do this either).
2: To tell the truth the only interaction Linuxcnc has with a parallel Port kernel driver is to get exclusive use of it. After that Linuxcnc code takes over. Anyway does anyone have any Parallel Port devices (printers, scanners, EEPROM programmers or the like) and it's not as if you can connect them at the same time. Yes yes CUPS or the like can try and use the port but who's trying to print when making chips ?.
3: There is 3 commands that are going to let you know that the Linux kernel has found your Parallel Port.All these will give you info regarding the parallel port.

Running the first command on my machine returns the following and identifies as being a combo card. the first command can also have aoption that gives more detail. The output of this has being truncated so you get an idea of what you are looking for.
The second, having a Serial port at 0x3008-0x300F and Parallel port at 0x3000-0x3002, as before the output has been truncated.
The third command not truncated gives you the address (0x3000) you use in your HAL file.
Of course the value you get at your site will be different, but this should be enough to get 99% of Parallel Ports working.

Notes relating to on board ports.
1: Either grab a user manual for your machine or open it up and look at the MB the header might just be there.
2: I know for a fact that Lenovo machines require a special parallel port header cable (there's some trickery involved within the cable that tells the BIOS to enable the parallel port itself and the BIOS page for setting it up, I'm saying this from experience).
3: There might be some other corporate machines similar, and the cables can be found and the on board port is usually easier to setup with Linuxcnc.

Testing, or Just Don't Connect Everything Up And Expect it To Work.
This is a great resource.
wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
Look at it, use it and browse the code, it gives an example of basic HAL & INI if you want to give it a go.

Other notes:
For Crying Out Loud do not connect anything greater than 5v to your Port, over 5v and the Genies That Operate the smoke valves will open them. The smoke you may not see, but the smell will burn and will not be forgotten.

 

1. Have you tried using 'HOME_OFFSET' to get the home position to where you want it?
2. You could use an MDI_COMMAND to call a subroutine and connect 'motion.is-all-homed' to the MDI_COMMAND

Weird, so the ms300 has an "actual speed" display, however in a cut that is clearly bogging down 15-20%, it is claiming a fixed frequency dead on the programmed one. Seems not to be an accurate speed... OR the audio is deceptive.

Get one of the cheap handheld  laser tachometers and see what it really is.  

Ok, forget about the supplied drivers, they are a waste of time, and usually only specific to the "advanced features" of the serial side. I swear this is always comes up in one form or another, just recently for this same chipset.

I don't why you're using Wheezy, with those specs Bookworm and a RT_PREEMPT kernel will be fine. But none the less. My Leneovo M72e has the same specs and is fine with Bookworm, a SSD boot drive is a good idea. If latency is a issue isolcpus=2,3 helps.

Please supply the output of these 3 commands:

Quick check. The delta drives have 4 in and 2 out each. So 12/6 total.

Not too bad. Beckhoff has some beckhoff io is $50 for 8 inputs. Plus the ek1100. that's quite viable here.

That encoder might help me diagnose things, thanks.
But it could not go on the spindle during use.

I am not trying to rigid tape or get a precision reading, I just need to know if the spindle is bogging down or stalling to I can halt the program.
