PCIe - No parport registered at "0x " . This is not Always an error.Continuing.

Category: Advanced Configuration

Had the same issue yesterday, PCI-E Sunix card, works perfectly but the error shows up whenever LinuxCNC is started.
Did not bother with it, but i did notice LSPCI does not show loaded module for it at all, but it does show all the other info with addresses and stuff.
 

Weird.

I have a Sunix PCIe Parallel port card that works with no error message.

lspci -v shows the kernel module as "parport" and displays 4 Hexadecimal port IDs, but only 1 works without error.

M19 and spindle-index-enable issues

@andy, seems I have missed your reply:

The point of IO pins is to only write any state to them when you want to set the state, and let other parts of the net be in charge at other times.


Looking at your code for case 0, which is the initial state, you are setting 'index_enable = 0' so this version of the component permanently forces 'orient.index_enable' low until an orient command is issued (ie 'orient.enable' goes true):
    case 0: // waiting
        index_enable = 0;
        if (enable) {
           if (enable ^ last_enable) {     // positive edge on enable
               is_oriented = 0;
               if (mode & 0x10){
                   index_enable = 1;
                   state = 3;
               } else {
                   state = 1;
               }
           }
        }
        break;

 Your code looks like it will always set index_enable true?


No, my version forces homing to index because the mechanism with adding 16 to the p word does not work and 'orient.index-enable' is not written to unless spindle orientation has been called (ie 'orient.enable' is true) because 'index_enable=0' is now inside the if (enable) { statement.
    switch (state){
    case 0: // waiting
        if (enable) {
        index_enable = 0;
           if (enable ^ last_enable) {     // positive edge on enable
               is_oriented = 0;
               if (1>0){
                   index_enable = 1;
                   state = 3;
               } else {
                   state = 1;
               }
           }
        }
        break;

Yes, I'm currently not home, so I dont know the specific name; but I tried the qtvcp_demo0 or something similar and it worked without problems.

I have a mixin class that reimplements the paint event. It first paints the normal widget then adds indicator painting.

I confirm and see the problem. I'll try to push the fix soon.

*halui_data->so_counts = 0;

should be:

*halui_data->so_counts[spindle] = 0;

Chris,

How are you adding the indicator lights to the upper right corner of the push buttons in QtDragon?



Thanks

M19 and spindle-index-enable issues

Category: Advanced Configuration

Yes that's the issue with the M19 command. But could probably be changed in a new release ??
I connect the orient.mode signal to a signal and then manually switch the mode.
An improvement might be to use a custom M command to change the mode (via mux2 or multiselect component)

One thing I might try is to change the orient.comp to have a input for running the index function, that can be controlled easily via hal or M command.

About the brake control:
I found the spindle.xx.locked pin in the documentation which goes high when orient ist done (and low with M5 or a new M19 command) --> it is perfect for controlling the spindle brake !

Oh great so i probably have no issue at all!
My drives only take 32-bit Integer inputs so that is fine.

Thank you!

since the core questions are answered:
I am building an air bearing Diamon Turning Lathe. The goal is to do single point diamond turning of telescope mirrors or similar.
Using ironless linear motors and high resolution glass scales. It is going to get calibrated with an Interferometer so i should get down to 100nm or so of straightness of the axes and linearity of the glass scales.

There will be watercooling of all relevant components down to about 100 millikelvin precision.
I am using Triamec servo drives.

The progress will be documented on my Instagram (Instagram.com/leo.wolf.the.engineer). Please follow if you are interested!

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Iv  finally got the encoder somewhat working. Just the confirm , the ec500 outputs a normal 0-10v signal for the spindle or is there a pwm conversion done in remora? I can adjust the spindle speed in the axis GUI and the 0-10v adjusts steady when measuring the ec500 VSO pin with a multimeter. When I am in CSS mode the spindle speed keeps dipping whenever there is a spindle speed change when X moves. If there is a lot of speed changes the spindle nearly stops. When I measure the voltage on the vfd 10v input the voltage drops on every speed change and then gets up to the correct voltage. Looking at the rpm scale etc in halshow show numbers steady when changing speeds. Any ideas what is causing this.

Hal floats are 64-bit doubles since 2.6 or so way back. But hal integers are only 32-bit, s32 u32. Not 64-bit.
Don't know how it is internally.

That sounds great!
So Linuxcnc is working with doubles internally but not outputting it to HAL in 2.9 right?

New to linuxcnc, basic question for DRO modes with encoded handwheels

Category: General LinuxCNC Questions

If you go the parallel port route, you will probably find you need to run at least two parallel ports. Encoder inputs can eat up a lot of input pins (3 axis would require 6 input pins.) But when you start to look at multiple parallel ports and buying add on parallel port cards, Mesa starts to look much more appealing. For example a Mesa 5i25/6i25 doesn't cost much more than a 2 port parallel port card, but is much more capable, and you know it is going to work with Linuxcnc, vs the crapshoot compatibility of buying a multi parallel port PCIe card. For example the last PCIe parallel port card I used only sort of half worked until I modified the breakout board by adding some external pull up resistors to some of the pins.
