Edit card name accordingly.

And there's this one:

www.apsx.com/apsx-nano-cnc-swiss-lathe

Nowhere do they explicitly mention LCNC.  It runs on "ASPX CNC software."

And yet...

All the g-codes, M-codes, etc. are identical.  Post processor is minor edit of the LCNC post.

Not sus at all.

Hello, great job with porting remora to these boards.
I went through a lot of post on this forum thread, but I'm not able to find the schematics for the EC500. Does anyone have a reverse engineering version of the PCB schematics? Thanks!

It's not a issue with Intel MACs
If you disable IRQ coalescing
and pin IRQs, You get pretty decent
performance.

For example on this HP8300 I have been running a test on a 7I76EU
with a 3 KHz servo thread for about 3 days while using the PC for general
web browsing, email etc and have not had any issues.
(CPU frequency is 2.9 GHz and times are in CPU clocks)

@PCW who would be the person group best suited to fixing it, and do they know about it? is this a linuxcnc thing or a debian thing?
 
Honestly its a Linux thing (broken driver) but would be easier to fix in a non debian compliant ISO
Ultimately it should get fixed in the kernel driver so the proprietary Realtek driver is not needed.

Interesting, would it help the intel adapter performance as well? bring it back to the 4.9 kernel day performance?  i miss those days...lol

The matrix_kb component can work with a 7I73 or any I/O device
that has input and output bits. With a 7I73, it converts a scan code byte
to individual key outputs. With a general I/O device it provides the row and column
output and input bits and converts them to individual key outputs.

Are you sure the 7I93 I/O bits are set in the proper directions?
 

it does have a speed display, i guess i could try to check the scales for both encoder and step scale. I will report back once i wake up, ty guys your help is truly appreciated!!

Hi Evrybody
I'm trying to write a post-processor to convert APT file (ISO4343) to ngc to get path working on LinuxCNC. A long time ago, unfortunaltly, I have thrown away my course of PP writing (it was in the early 90's for CATIA v3 with FORTRAN). I have not practice since this time.
I'm slowly learning Python for this.
Is anyone have an idea how-to ? APT language ? How to structure program ? ...

Hello,

I've tried to set up matrix_kb with 7i93 using 3x3 matrix at a first time but it reads all buttons in one column as pressed (of course I press only one button).
I've tried to use diodes to separate buttons without success.
I see but doesn't clearly understood that matrix_kb is mainly designed for 7i73, is this correct?
Should it work with 7i93 or must I go with 7i73? 7i73 for me wouldn't be a convenient solution because my 7i95's SS ports are configured as SSI interfaces for ABS encoders so it would be difficult to connect an additional 7i73 to it.
Any other ideas/workaround to be able to connect about 30 buttons to Linuxcnc without using 30 inputs?

Thanks a lot.

Raspberry Pi 5 support

As you may have seen in the rp1lib thread, I've been working on RPi 5 SPI support for LinuxCNC. It's ready for some testing and feedback!

github.com/scottalford75/Remora/tree/mai...omponents/Remora-spi

This version of the Remora component will detect which Raspberry Pi version it is running on and load the appropriate SPI and GPIO drivers, BCM2835 or rp1lib.

For the Raspberry Pi 5 there is future features that will need to be added to the loadrt command line:

1. The RPi 5 has 5 SPI instances available on the header
2. Each SPI instance has a choice of 2 - 4 chip select GPIO pins
3. Different method to configure frequency

For those that wish to test, remember this is a Beta version. Bugs may still be present.
 

Does the servo drive have a speed display?
If not, Do you have something to check the spindle RPM?
If not, do you have an arduino and a photo resistor or optical sensor?
All these measuring should be done with no spindle feedback in hal as not to mess up the readings when commanded at a certain speed.
-
The encoder feedback RPM is easy to find manually, set the hal show to show the raw counts from the spindle and rotate the spindle by hand 1 full turn, adjust the scale accordingly.
-
This is untested, but setting the spindle as an axis and the output scale to 1 and checking how many mm it takes for a full rotation by using MDI or just jogging, would yield the actual scale.

well that comment is from the creator of the spindle section (tall83). It is not from my servo so it should be unrelated to my setup.
Unfortunately my manual does not give any info for the step scale.

I think the output scale should be 166.6666 (or -166.6666) as the ini file comment suggests.
This is completely unrelated to the encoder scale (which seems to have been factored in)
(at least assuming 10000 steps per turn)

with both you mean the step scale and encoder scale i suppose.

Yes i agree, the problem is i dont really have a way to find that out myself i believe.
The parameter that shows the factory default says 1024 motor resolution per revolution.

you should give it a shot if you are able, unrelated to probe

but the on abort stuff doesnt look like it will effect probe stuff, as it is advised to use the probe abort button on the probe panel [x] button
