PathPilot V2 source code

Category: PathPilot

The tp source is not available yet as far as I've been told.
I have also been told its pretty far deviated, so it will not be a simplistic task to add it to the main.

This is just 4th hand information though, and I know nothing about coding so take that for what it's worth :)

What current are they set to?
I have mine at 2A in a shop that gets to 55 degree C in the summer (around 0 right now) and had no issues with them, but i would venture a guess that the one faulting has the chip not laying flat on the cooler, so open it and check if the board/chip are flat and the thermal pad is in place.
Mind you, as a general prevention i did open all of them and also added thermal paste between the chip and pad and heatsink and pad.
All on closed enclosures with no fans.

That makes sense. I thought that would be the problem I just wasn't sure. Thank you very much

Today was a hot day ambient temperature was about 40 degrees Celsius

And the controlbox was switched on all day.
So when I cut a long cut suddenly one of the drivers got hot and shut down. So the tandem axis pulled skew and messed up the whole thing I was cutting.

My control box has no forced cooling would forced cooling help prevent this problem
Or could it be that the driver is damaged?

I'm trying to get the gowin toolchain up and running on rpi5. It gives me an error when execute making all.
cnc@raspberrypi:~/riocore/Output/TangNano9K_spi_rpi5/Gateware$ make clean
rm -rf rio.fs rio.json rio_pnr.json rio.tcl abc.history impl
cnc@raspberrypi:~/riocore/Output/TangNano9K_spi_rpi5/Gateware$ make all
gw_sh rio.tcl
/opt/gowin/IDE/bin/gw_sh: 2: Syntax error: Unterminated quoted string
make: *** [Makefile:34: impl/pnr/project.fs] Error 2
cnc@raspberrypi:~/riocore/Output/TangNano9K_spi_rpi5/Gateware$ 

I see you've already mentioned this error. I downloaded and cloned the dev version and it still doesn't work. Any tips...

I see there is another option 'generic_spi'. I will test that on rpi5 too just to get that toolchain working. I don't want to take the TN9 out of the device and program on windows anymore.


 

I found the gowin toolchain a major problem to get running on a few systems like a current LTS release of Ubuntu, so I built a docker container for the oss-cad-suite. Meister added one for the gowin toolchain, and one for oss-cad-suite on the pi. I think the pi one should work fine on the pi5 too.

I was able to flash directly using the oss-cad-suite one with a T9 on a pi4, but it's been a while. At the very least, the Dockerfiles have the details on getting the toolchain working.

Give this a try, it's the oss-cad-suite instead of gowin but it supports the T9 IIRC.

I get the command line console and it quits out with ctrl+d as you say, but I'm still getting the same issue, I had changed the filename to something other than config.json to suit the machine, so I changed it back to config.json but no dice.
 

It might be easier to use the docker container, see the documentation in the git repo. github.com/multigcs/riocore/blob/main/DOCKER.md

Otherwise, gw_sh must be callable in the same terminal session you start the riocore tooling in.

It may be simpler to add the gowin bin path to your system path.
Start a new terminal, and 
echo $PATH

if you don't see your gowin bin dir listed somewhere in there, how you're setting the path is not working.

In case you weren't aware, on a digital-input selector switch - say for jog increment - you only need 2 input pins to have three available states.

Both inputs off = state/value #1 (just leave this switch pole disconnected)
In1 on, In2 off = state/value #2
In1 off, In2 on = state/value #3

 

I am aware, but I also need two input pins for four available states, so I don't have any practical reason to limit it to three. I hadn't originally planned to go all the way from micron to mm on the scale, I can do it with no extra work, so I will! The axis selection switch will be off + x + y+ z. That is, if that's even allowed LOL.

In either hardware case, I think the HAL file magic lies in using a HAL component named wcomp.  If you’re not familiar with LCNC and HAL, ‘components’ are like little mini-programs that create virtual pins with behavior specific to that component.

linuxcnc.org/docs/devel/html/man/man9/wcomp.9.html
 

A Google search of HAL WCOMP LINUXCNC, in any combination, returns zero results. However, I found a manual last revised in 2007 so it wasn't all for naught: linuxcnc.org/docs/2.1/HAL_User_Manual.pdf

I'll do some reading. Thanks!
