USB CNC Pendant project

@ajmartins The errors look like these two lines might be missing in your config.g, can you check that?:

M98 P"pendant-continuous-init.g"
global run_daemon=true

Or you can run them manually in the console once for testing.

And about your other question, doesn't your WHB04B-6 show the coordinates on the LCD?
It should work automatically...

ajmartins

Yes, i added both lines to config.g, i tried manully running and i get the other error i sent.

If i run M98 P"pendant-continuous-init.g", the system just stalls and i need to reset the board.

Should i put both lines in the end of config file?

ajmartins

@ajmartins Well more tests, added both lines to the end of config file, and now at least i dont get any errors when restarting the board.

But when trying to make a continuous move, i still get the error:

Error: Failed to read code from macro pendant-continuous-run.g: Failed to evaluate "{exists(param.A)} && {exists(param.F)} && {exists(param.D)}": unknown value 'param.A'

@ajmartins Which version of RepRapFirmware have you installed?
I'm wondering if the macro parameters or the exists() function for them is "too new".
On my machine I'm running 3.4.6. And from the changelog I guess that at least 3.3 could be required.

ajmartins

@hurzhurz Im running the same, 3.4.6.

hurzhurz

@ajmartins It looks like the Duet Software Framework (DSF) is version 3.4.6 (you are using the Duet together with a Raspberry Pi, I guess?), but the Firmware on the Duet is just 3.1.1

ajmartins

@hurzhurz Yes, you are right $:\$ since i dowloaded the PI image yesterday i suposed that was already with last version.

I will try again.

Thanks

ajmartins

Its now working perfectly

Thanks

@ajmartins Great, happy to hear that!

@hurzhurz I want to thank you for the fantastic work you have done.

I started looking for a pendant solution for my CNC roughly a week ago and today I finished the build. Almost plug and play with the instructions you provided. Amazing to have a wireless pendant. Still surprises me that it works.

Only thing I had to figure out was where to put the macro folder. It should be in the systems directory and not the macros.

Total cost was 200€ for the six channel pendant and some spare raspberry picos, Panel USB and such. It worked first try and no smoke was produced during the build.

I’m truly grateful ️

@Perplexed Thank you for the positive feedback! I'm glad it worked out well for you

Hopefully I will find some time to start working on this project again.
I did start to implement the use of a config file to make it more flexible, which I would like to get finished at some point...
