Hi folks!

i try to get my loved MPG in action in Linuxcnc, but i struggle..

when i ask lsusb i get told its a:when i ask cat /proc/bus/input/devices i get
when i run "halrun" and type in:
loadusr -W hal_input Code Mercenaries KeyWarrior Combo O Commander
The keys get loaded, but they get loaded 5 times!
I am told that the name for the device is "Code Mercenaries KeyWarrior Combo O Commander" ,
but the message also shows 5 times!

What am i doing wrong?

Whats confusing to me too, is that i cannot use 
"loadusr -W hal_input Code Mercenaries KeyWarrior Combo O Commander" , that one won't work, only without " , its accepted.
As far as i know, you should always use " when there are blanks in a name / path.

Thanks in advance, Tom


 

hey i just saw this and had to comment as i have been down this path about 10 times on big machines.

my experience when i looked into it was that using any of the fanuc stuff was just not worth it compared to new chinese servos. i use the Yuhai brand (have bought like 70 of them now)

a 2.2kw motor and drive 200v input power costs like 300 usd per axis. so 600 usd total. and you get new motors and drives that don't have issues. i tried keeping old electronics going too many times and it didn't work out for me. the i spent like 1000usd trying to fix old fanuc drives and then heidenhain fagor misubishi etc eventually i just come back to what i should have done in the first place and just bought new motors. anyway after 7 years and over 70 motors ranging from 400w up to 4.5kw i have only ever had one motor fail. and no drives and i think that was our fault with bearing misalignment the zaxis brake failed in it. But it is truely nice to just turn the machine on and know that it's just going to work.

also china has very nice vfd drives now you can get a 11kw drive for 200usd. or one that can turn a normal motor(like a pump farm motor even..) into a pretty rigid servo drive for about 900usd for 11kw
anyway let me know if you want any advice cheers

i am interested also in this as i have a large mazak horizontal cnc with a 80 pocket toolchanger and sister tools and tool time tracking will be nice so i will look at this when i get to it. machine is almost running cutting parts so close now

yep no stress. hopefully as time goes on people will test this and use it. just would be a waste if it never got used. But i have 7 cnc machines myself that are getting the conversational stuff and a general upgrade of linuxcnc. and it's worth the time just for me so not too fussed if no one else uses this. machines are getting pretty cool now. with all the auto tool measure stuff it all makes a massive difference how fast jobs get done. and auto tool measuring means that i don't get the chance to make mistakes with tool offsets and they always stay loaded so i don't do any hacks. cause the fastest option is clicking measure and walking away to carry on programming on cam

cheers

man this looks just like my place in NZ you get the machine bug and it bites hard aye lol. and then its more and more machines until its hard to stop

First of all, thank you very much for your interest and support. The diagram you sent already formed my starting point. However, since there is a 90-degree difference between the slider joint and the next joint, I wanted to redo the calculations.

Also, since Genserkins only supports rotary axes, I will not be using it. I will recreate the kinematics according to my system.

Is the DH parameters below right?

Those won't work. First indication is the simple fact that you are mixing distances and angles. Also note that genserkins uses 'modified DH' parameters not the standard 'DH' parameters.

I already posted the parameters for your robot that should work for your robot, why don't you start by trying those?

Moin,

ich bin der Meinung, dass es nichts mit linuxcnc zu tun hat, sondern mit
fusion 360..?

Ich habe das Programm in fusion 360 mit dem Prozessor von estlcam rechnen lassen. der fährt die kontur ohne radius, dass hat 
funktioniert. Der Postprozesseor von linuxcnc sollte beim abfahren von Konturen vielleicht doch noch überarbeitet werden.

The Linux CNC FPGA control board I bought connects to the motor driver, and it works perfectly with the 74HC245.

There is no problem connecting the DM542 using the 74HC245.
 

The FPGA (3.3V) is directly connected to the 74HC245 (5V).
 

it's the data received by the controller from drives

Is the DH parameters below right?
 
 

Any LinuxCNC users that have an opinion of PureCutCNC?
I'm not involved but it look kind if nice.
purecutcnc.github.io/

Press the "home all" button, then issue MDI.

Tut mir Leid für die Falsche Fährte.

Ich habe das Problem nicht reproduzieren können in meinen Testconfigs. dürfte ich deine INI sehen um die zu vergleichen?

managed to fix this by completely rebuilding the config, no idea what was causing it
