- UART control of TMC2209 stepper drivers (set microsteps and phase current via HAL pins, can adjust at runtime)

I am sure the form member 3dtech_ks will be very happy for this, he has a strange obsession with TMC drives and printer boards!

found something, a clue but not the reason why, i suspect its a remnant edit from working on the tool table database mode, running a comparison to see where we broke it, looks like its not reading newly added tools at startup which triggers the error message because the tool isn't read into linuxcnc at start up. will update when a fix is up.

Hello everyone! I'm hoping for some insight on linux cnc if this could be the right choice for my end goal, I have and old cam machine Im hoping to retro fit with a cnc control to elimate have to design and cut new cams for each part, I have a decent understanding of the machine and how it works. Tho I have never tried something like this tho (a cnc intergration)
The machine would be 2 axis z,x it has to fixed tools that simply swing in and out on a tool head that work oppsite of each other 1 goes in 2 goes out vice versa.it has an 8k spindle Also a 4000 rpm material straightening unit. with a carriage that move foward and back. 
The timing is all done by cams, belts and chains. 

Is building a system like this something I can do with linux cnc? Is this a feasabile project for intergatation?
Any resources I could check out beyond this site maybe people who have attemped similar?

Any tips, information and thoughts would be welcome 
attached is a photo of a machine similar to what id want to retrofit

 

i am getting it with tool 199, this is a wierd bug, I am digging into it but im having trouble finding where its coming from. I am not finding any of the error information in the debug or any of the src files, I will report back when i find something more on it! thanks for bringing this to my attention!

I suspect you need to only enable the tristate when orienting
otherwise your digital output 07 will control index enable
rather than the encoder hardware for G33.

EDIT: Never mind, that does look like what you are doing.

Is motion-digilat-out07 false when you try to rigid tap?
 

hm2_eth: loading Mesa AnyIO HostMot2 ethernet driver version 0.2

You still have the Ethernet driver (hm2_eth) invoked in the hal file, you need the
RPI4 SPI driver (hm2_rpspi)

This might be better as a new thread, but this one was already made so I'll just tack it onto here...

Over the last year I've occasionally been adding new functionality to this 'weenyPRU'. The PC that was running my large router died so now I'm running it with a Pi4 and one of these units. Looking good so far.

The new features are:
- UART control of TMC2209 stepper drivers (set microsteps and phase current via HAL pins, can adjust at runtime)
- XGZP I2C pressure sensor (150Hz), will be used to sense vacuum pressure in my SMT pick-and-place
- DS3502 I2C digital potentiometer, currently using this to control the VFD of my router
- HX711 load cell amplifier (80Hz), will allow my pick-and-place to probe heights

The poor little F103C8 is now looking very busy, not sure if it can be pushed to do much more than this. Here's a scope of some load cell testing:
 

From your error report:
./CNC_V_Mill.hal:10: parameter or pin 'hm2_7c80.watchdog.timeout_ns' not found
6722
So just omit that line in the hal file and try again.

Try eg

Or should I be looking elsewhere for the tapping-won't-start problem?

IIRC the spindle position must also increase by +1.00 for a single CW rotation of the spindle (although I would kind of expect that to be the case as you already have spindle orient working).

While using a rotary axis for a tool changer does work it is really a rather outdated way of doing things. I would recommend looking at the 'carousel' component that handles tool changers in HAL rather than exposing them as axes.
linuxcnc.org/docs/html/man/man9/carousel.9.html

Also here is a video of somebody explaining the basics of a M6 remap procedure required for tool changer integration:

Hello!!
I want to implement ATC using mesa 7C81. Here I want to use A -axis for rotary, so as i get command for tool change my rotary axis (A axis) should rotate. Please help me how can I handle A-axis with tool change command. What changes are required in ini, hal file and tool.tbl.

Thanks

I had the idea to purchase the Mesa 7C80 board and a Raspberry Pi 4B to build my own control panel and have run head first into a severe lack of knowledge coupled with almost zero sources to find answers. I have used Raspberry Pis for other projects like media servers and 3d printer farms but I have really over extended myself on this one. I would greatly appreciate it if some of the individuals here that have successfully configured their own machines could assist me and hopefully I can build a guide so that others can learn how to configure these boards since they really do seem to be worth the investment. 
1) I downloaded the Debian image shared by user shepherps and loaded it into my Pi. www.linuxcnc.org/iso/rpi-4-debian-bookwo...23-11-17-1731.img.xz
2) I adjusted the config file in the SD card to allow SPI
3) I modified the ribbon cable purchased from Mesanet so that it was about 2 inches long.
4) I changed the Region setting to US UT8  (I was receiving errors just trying to calculate the steps in pncconf and found the answer to be this)
5) I used mesaflash to verify that the board could communicate with the Pi
6) I used pncconf to generate the 7i96d with ini substitution enabled and then changed the instance of "CARD0=7I96.0" to "CARD0=7C80.0" 
7) Changed "hm2_eth" to "hm2_rpspi" in the .hal file to change the communication driver from ethernet to SPI

To be honest I'm basically a script kiddie when it comes to Linux and Pis, I'm more of an arduino and FANUC guy so most of the other threads have gone over my head but I used to be proficient in DOS so far from intimidated by the terminal. I have attached my most recent error log to show where I'm stuck at now.

Unfortunately a flywheel will not work either. 
If the compressor starts during probing it will only run for a short time and will cut out because of under voltage. 

I do not cut a lot yet. So I can’t afford a diesel generator. 

Hello, I have a stupid question. How to do a tool change without stopping and waiting for a change tools. I use gmoccapy .
I am currently changing the tool to T6 M6 G43 . If I load T6 G43 does not load the tool offset.
Thanks!
