New ethercat / probe basic control for minimonster

Category: CNC Machines

ok, z motor hooked up and powered.

im basically lost at this point.

anyone want to walk me through or point me to nice simple sequential "do this then this" instructions?

as of right now i did the ethercat install, and nothing much else. if i type ethercat slaves in the terminal it shows me nothing.

here is my drive manual
www.megatech.ro/doc/590/Accurax%20G5%20w...20Users%20Manual.pdf

thanks!

Hello,
Does anybody know how data is formatted for NVMPG to display XYZ data, etc.?
I wanted to use this mpg in another project, but I cannot make it work from source files for stm32 and linuxCNC.
If anybody has a spreadsheet of these signals or a logic analyzer to see what is going to the mpg, I would be grateful, and I could make a tutorial about using it for other stuff as a cheaper alternative to other mpg.
All I know for sure at the moment is the baudrate and button codes, but it was an easy part of it...
Thank you in advance

I think it needs to be approved but there is a link that takes you through to the comments on their forum.

As Tommy said, balls screws are a poor choice as you can't get the speed out of them and they whip.
Either belts or rack and pinion (with 3:1 to 5:1 reduction)
nodocs has changed. refer the docs :)

The attached is old hal code that Todd helped me with  which uses, red, orange and green lights. The green light flashed (via siggen) when a program was paused. red was from the estop

The Run/Step/Pause/Resume part is described in hal examples on the forum but it won't work with QTplasmac which has its own pins that achieve a similar result.

Her is and example of it running. I did eventually wire this into some stack lights like you show,

G7x and profile in subroutine with parameters

Category: G&M Codes

Hi,

I'm trying to write a macro for touchy that provides the option to specify the x/z coordinates of the G7x profile on the touchy user interface. 

My initial thought was subroutine nesting but I just found out that I cannot nest subroutines. So this does not work:


O<g7x_macro> sub
O100 SUB
...
O100 ENDSUB

G71.1 Q100 ....

O<g7x_macro> endsub


What works (a bit) is to put the profile subroutine after the main macro (before does not work).

O<g7x_macro> sub

G71.1 Q100 ....

O<g7x_macro> endsub

O100 SUB
...
O100 ENDSUB

But now I struggle with getting parameters to the subroutine. Does anybody have an idea here?

These plots don't look correct. Try using halscope. This plot shows on piercing the arc voltage goes right off the page almost instantly then it falls below the cutting voltage before stablising around the cut voltage.
The blue line shows when the THC was enabled and you can see that the voltage has already stabilised before it comes on.

Mesa makes a board that does pwm to analogue.

Yeah I went that whole route when I was using machine kit and a beagle bone black.
It's a shame that the BBB hasn't had a upgraded CPU with the PRU and more memory. Was a great little platform, actually still is but a little underpowered.

Will agree that there are some great tools out there. I still have a copy of the DOS version of EasyTrax I was given by a very surly PCB maker, top bloke but didn't suffer fools.

How would I check this? Toolpath looks complete when zooming in and the "show toolpath data" looked similar for all the circles. I also tried a different part and it came out fine. The selected contours are all closed chain, so not sure what is missing with this part.

K, installed ethercat... I guess..? haha. i need to decipher all the instructions.

BUT, I have another problem. setting up the servos it seems the configuration software is $500? This makes no sense to me. Never seen a drive where you had to pay extra just to configure and tune it. Am I missing something here? Anyone using Omron G5 servos?
