LED to indicate M3/M5 status

Category: GladeVCP

Can you post the code to do this? I've tried various things but my LED pin is not seen (although it shows in HAL monitor as gladevcp.LED1)

5i25/7i76 analog spindle control on Lathe spindle

Category: Basic Configuration

Did you verify that you get 100 counts if you rotate the spindle one turn by hand?

Is the scale in the INI file 100? (or -100)

step/dir spindle control

Category: PathPilot

That makes sense. I don't think PathPilot uses it for any other duties. I'll change the value to 50 for a 50% duty cycle.

Thank you.

5i25/7i76 analog spindle control on Lathe spindle

Category: Basic Configuration

I can't think of anything that I have that would allow me to do that.
I edited the first message to add my ".hal" and ".ini" files.

One thing that seemed weird to me was in pncconf. Even though I had single input 100 line encoder checked, if I go into "calculate scale" it shows 25 line encoder x 4.

So is the encoder scaling wrong? (2x too high)

Is there an independent way to measure the actual spindle RPM?

I turned on the spindle in Axis and bumped the speeds using the "+" button.
Here are the RPM outputs for CMD vs FB using HALSHOW:
CMD   0   101   201   301   401   501
FB       0  180   390   600   800 1000

FB is an approximation because it was fluctuating over a range of about 20rpm.
Spindle basically maxs out at 500rpm commanded.

Setting Up BLDC spindle motor in Forward/Reverse direction. was created by amanker

Setting Up BLDC spindle motor in Forward/Reverse direction.

Category: Basic Configuration

I have setup linuxCNC using remora.
Its working nice. I want to replace PWM DC motor with BLDC motor.
BLDC contoller has enable and direction pins and 0-10V input pin. I am using PWM tp 0-10V converter.
When I use spindle i forward direction then its working. But in reverse direction its not rotating. I confirmed manullly that spindle/contoller is working ok in both direction.
I can see m3 and m4 signals properly triggering suitable pins. on m3 and m4 I can see enable pin is getting voltage. and like wise direction pin is also working ok. 
But I have noted that PWM out is only working in forward direction. In case of m4 there is no PWM out on pin.
Please help me.
Here is my HAL file.

Do you have any example of handler to replace dilog ?

I may be end up with rewrite pistprocessor adding pause / msg before tool change

Im ok with remap/sub call /etc

Give it a try, it is not permanent.
Linux had issue with Intel 915 chipsets and they were blacklisted in Linux for a long time.

You are looking at 'ini.0.' values. Those correspond to the [JOINT_0] section in the ini file. If you want to see the [AXIS_X] values you would need to navigate to 'ini.x.' which should be lower down in the list on the left hand side of the screen shot.

Hi Tommylight,

Thank you for your swift answer, in my case, the PC (Lenovo Tiny M600) is equipped only with the Intel graphics, which has only Displayport as video output. I´m connecting the screen through a Displayport-VGA adapter (It worked during the installation and GURUB menu, but that´t all).

Is the "nomodeset" solution still valid despite not having Nvidia?

Thanks!!!

Thank you!

I cannot find the limits I marked in the picture on halshow.
When I change the limits below joint_0, the machine stops at the limit, but I cannot move it again with the jog keys.

hi
Thanks @tommylight and @elovalvo
these are two paths that I have already taken without success
the headers for the kernerl 6.6.45-rt39-v8-16k are not found.

Now I'm going away for a few days, when I come back we'll see

thanks a lot
