Ethercat compatible Encoder board tentative STM32F4 + LAN9252

I will not use DC yet as it sounds too complicated at this stage
I setup a Linuxcnc on my personal server. Everything is recognized but the counter is not working.
Its in PRE OP, maybe this is the issue

LatheEasyStep – experimental QtVCP macro for step-by-step lathe programming

Category: Qtvcp

Hi,
this looks really cool, thanks for sharing! I’ll definitely be testing it once my lathe is ready.

I really like the idea of solid onboard solutions. If this works well, you could do around 90% of lathe parts without external CAM, which would be a real improvement.

It reminds me a bit of Native CAM. Do you know it?
If so, I’d be interested in what made you decide to develop a completely new macro. From my point of view, Native CAM on the turning side is mainly missing proper G71 support and a polyline tool (which already exists in Native CAM Mill).

This is not meant as criticism, I generally find new developments very exciting. I’m not a programmer myself and can’t really judge the effort involved, which is why I’m asking.

Either way, very promising project. Looking forward to seeing how it develops

greetings 
Tom

Probe_Basic ToolTouchOff

Category: QtPyVCP

Sorry to bring the topic up, im trying to figure out what is wrong with my Probing in PROBE BASIC.

The Carousel, tool changing, homing, spindle S line, everything is good. Im running Ethercat XYY and Mesa Z and Carousel simultaneously. All good.
The problem is in the Tool Touch Off Macro, and defining my part coordinates.


- When i touch off my tools, the tool lenght which gets written on the table is very weird - not consistent with the tools im measuring.

- My probe is not on the part itself, but on a specific place on the table. So, after 'zeroing' the tools, i should also zero the part.

As the tool touch off macro is giving inconsistent values, currently I am placing the tool at almost touching the part, and hitting "Zero Z", and changing every tool with MDI codes M6 T(Tn) G43 H(Tn). Placing the tool at the top of the stock surface and hitting "zero Z" is the correct procedure , if im measuring the tools correctly?

Any ideas as to why are tool lengths being inconsistent?

My Spindle nose doesn't reach the probe - due to machine mechanical limitations. I can only touch it if i have a cone + tool. is this OK?

I think you know this already, but you have the output of "sudo dmesg" with the last lines being relevant.

In this case, do the following commands work "ethercat -p 0 upload 0x2701 2" and "ethercat -p 0 download 0x2701 2 1"?
You are aware that bytes in sdoDataRaw are LSBF so your number "00 00 00 40" is 67108864?

Please start linuxcnc from the command line and check the output there. 
You will see there the error that does stop your panel to be embedded.

7I96S    CL57

STEP-   PUL-

SW3 Set for 5V mode

The ENA, ALM and BRK can be left unconnected

I have a similar setup I'm building. If I wanted to use the ENA and ALM as well as STEP/DIR, which position should the S3 switch be in 5V or 24V? I know the 7i96S provides 5V power for STEP/DIR but my field power is 24V. Can I do this or would I need to provide a separate 5V power source for my ENA/ALM signals?

Category: Driver Boards

Is the "unplug and plug" thing correct, meaning is it the same pinout for SSerial on 7i96S and 7i85?
Sorry if i messed that up, i never used a 7i85, yet, it was just an educated guess from experience with Mesa boards and very consistent pinout.

Pico Universal PWM Won't boot Random pins not working was created by LearningLinuxCNC

Pico Universal PWM Won't boot Random pins not working

Category: Driver Boards

So I have not used my RB1-CNC machine for a while. I tried starting it up today and I am getting errors on load that have to do with not being able to find pins on the Pico Systems Universal PWM board. Sometimes it won't find the board at all other times it won't find an generic IO pin other times it won't find an encoder pin.

This was working then I had to reconfigure from 2.7 to 2.8 and got it working again and now after setting for around a year I can't get it to load into linuxcnc unless I comment out of the hal files that tie to the pins on the UPWM board.

Here is one of the error outputs.

tommylights suggestion is on the right track,
Modbus needs RS-485 and the 7I85 serial interfaces
are RS-422 only (no TXEN).

What if you connect the 7i84 to the 7i85 and use the 7i96S SSerial for PktUART ?
Just an idea as wiring the 7i84 to 7i85 works without any setup and requires simple unplug from 7i96S and plug to 7i85, but also editing the hal to change the SSerial card channel.
Edit:
See below about SSerial on 7i96S and 7i85

Anyway, back to the problem in hand. When I run my installation, I'm getting a lot of missing content in the "cycles" tab:
 

And the command line errors currently look like the contents in the attached text file.

It looks as if there is something seriously wrong in the Gtk / python / gladevcp bit. Could somebody suggest how I might troubleshoot / resolve these errors?
LinuxCNC seems to run OK but the macros are still not showing up. Many thanks.

Category: Computers and Hardware

Hi, remora-1.1.0 is now over 4 years old. Please try the main branch which will give you the latest remora-spi component.

That's a very slow SPI frequency and is probably taking longer than a servo thread to send the full packet, hence the lag.

I'd suggest working on your noise issue to improve it as much as possible so that you can increase the SPI frequency. An occasional "bad SPI payload" is not a show stopper.
