Remora DMA Code in other Builds?

Category: Computers and Hardware

I'm running Flexi-HAL and it doesn't support DMA and wanted to know what the best route to take to get there. I need 250KHz for my CNC. It uses a STM32F446RE.

Mapping key codes to specific jog rates was created by scsmith1451

Mapping key codes to specific jog rates

Category: Advanced Configuration

Reviewing the documentation, I noticed that there are two functions that can be used to set values associated with key codes, set_rapidrate() and set_feedrate(). Is there a corresponding function to set the jog speed such as set_jograte()?

One more problem, LinuxCNC is using 3-axis (xyz) readahead, so if you are using xyz+(abcuvw) axis blending in G-code command, the speed will be very slow

That will depend on the G-code. The slow motion in combined moves is to do with the requirement in the simple path planner that the system can stop in the next segment (if it turns out to be the last segment, because without lookahead it can't know what the allowed exit speed is for the current segment) 
If the G-code is very short segments, this becomes a limit to the speed. But if the moves are long, the system can run at full speed.

You could try Geany (which we include in the LinuxCNC distribution because it's quite a well-behaved editor)

If the script fails then it needs attention, your config may be a useful test-case to improve the script.

This is a general Linux / Debian question rather than a LinuxCNC question, so you might need to broaden your search.

Might help?

What would it take to merge the Tormach TP into LinuxCNC? 

That's a good question, and it's something I want to look at. 

I did get as far as making a hack-job combination of LinuxCNC and Pathpilot:

If you are an experienced C-coder with time on your hands.....

The internet is connected, but the browser is not allowed to browse because of the date and time. When I installed LinuxCNC, everything was working.

halui.mdi-command-NN pins not showing up

Category: HAL

Looking through halui.cc I don't see anything that would obviously fail if joint 0 is angular.
But as an experiment I would be tempted to switch COORDINATES to ZA to see if anything changes.

It might be instructive to see which halui pins exist, to give some indication on where the component load fails:

github.com/LinuxCNC/linuxcnc/blob/master...mc/usr_intf/halui.cc

Assuming that linuxcnc is "alive" "halcmd show pin halui" should give us a pin list to look at.

I think that, if you connected to the internet, the date and time would correct themselves. So I would start with debugging the internet connection.

I'm not sure, to be honest. I wasn't specifically looking for the ethernet version of the boards, as they don't seem to be the most popular option here (or at least that's my impression).

From what I've read, the ethernet version usually has a 1 kHz refresh rate. My goal was to find the most reliable configuration possible, so if I messed something up, I'd have a solid backup.

No idea how you got to that conclusion as probably 90% of new posts are for Ethernet cards, and i have at least 30 in daily use with no issues ever.
And most ethernet Mesa cards can easily do 4Khz, so there is no difference between the interface types, at least not major differences in use. Also have over 30 of PCI and PCI-E cards in daily use, with no issues ever.

My machine has mpg wheels to control feed and spindle, halui.feed-override.counts and halui.spindle.0.override.counts
Is there a way, to make the sliders follow the adjustement with mpg wheel?

Yes, a 7I73 (or other sserial device) can connect directly to the 7I97T

1 KHz is the default LinuxCNC servo thread rate and is typically fine for
normal CNC machines with velocity mode servos.

You can add multiple Ethernet cards with a switch or multiple Ethernet ports
