Please run LinuxCNC from the command line, then we will probably see what the error is

and what does this mean? thanks

same values or i am wrong??

Note the missing spikes (colored in blue/red) at the extreme left and right of the graph.

or a 7i92... i payed for both cards 100 euros...

so for my information... on a normal pc like optiplex 3020m or lenovo m73 tiny.. i have latency under 2000... but i never looked this way in the histogram.

can you explain me the spike?! please

Thanks, given that this issue only happens once a week or so, is the output logged anywhere?
This table gets some pretty heavy use so maybe it will be a good candidate for finding bugs.
Its probably not 100% current but the config is here
github.com/rodw-au/showstopper

'LIB:basic_sim.tcl' is used for simulation configs only. Also '..._cmd.hal' files are created automatically in sim configurations those do not exist in configs for real hardware.
Modifiying a simulation config to run real hardware is something I would advise you not to do. Instead I recommend to start out by creating a 4 axis config using pncconf (I don't know if fthe 7c80 is supported but I presume so).
- Get the four axes tuned and running smoothly.
- Add the 5. axis manually by copy/paste/modifying the relevant sections in the hal and ini files and get that also running smoothly.
- At this point you can then use the sim config as a reference on how to change to xyzac-trt kinematics.

Also when asking questions about a config you are working on it is usually a good start to attach your hal/ini files and any error messages you are getting.

Assuming you use the 7c81's FGPA for stepgen and don't sofware step, you don't need a base thread so latency requirements is much relaxed. I'd be happy with anything under 130,000 with 200,000 at a pinch

Thank you PCW - wasn't expecting any reply on Sunday:) Wow

on ny m73 i have a jitter of 1000... so what is the reason thst you say that this latency is good???? thanks

glad you figured it out!

ey Giovanni

i had another try today getting native cam working

i have a tab now with nativecam but its blank

this time i got right through the guide you did right to the end without errors

do you have any ideas?

i want to make a video after i get this working for the next guy lol
 
cheers

Yes, there are over 20 messages saying it upgraded but not one message saying it got an error and failed during that upgrade attempt.
You can see I tried several times tying to get to the bottom of it, each generating a message.

The issue is that on two different PC's, the upgrade to a sim install failed without reporting an error which left me in the dark.
You seem unwilling to actually test such an upgrade process and instead want to blame my installation.
 

Here's a 7I95T config with all 6 stepgens replaced with PWMgens:

 

Its a existing config but it's not on the distribution image for some reason.
(I'll fix that Monday)

Note that you should choose the PWM output pin polarity so you get the
low state at power up/watchdog bites (this may also require inverting the PWM
outputs in the hal file)
 

 
Hi Guys!!

I decide to configure a 5 axis machine for my project, but my knowledge is not as those guy on youtube, but i wish the linuxcnc community could help with their knowledge.

using vismach 5 axis configuration on a mesa board 7c80. Installed linuxcnc on my rasberry 4.   
xyzac-trt.hal keep changing every time i run linuxcnc but I know that they are related with a file *.tcl on hallib but my question can I delete those files and only use *.ini, *.hal only using those files that are essentially need it. 

also do I need to use all the parameters of 7c80 to make the axis to move?
because the I had identified that the linuxcnc only used some of themhm2_7c80.0.stepgen.00.control-typehm2_7c80.0.stepgen.00.countshm2_7c80.0.stepgen.00.dbg_err_at_matchhm2_7c80.0.stepgen.00.dbg_ff_velhm2_7c80.0.stepgen.00.dbg_pos_minus_prev_cmdhm2_7c80.0.stepgen.00.dbg_s_to_matchhm2_7c80.0.stepgen.00.dbg_step_ratehm2_7c80.0.stepgen.00.dbg_vel_errorhm2_7c80.0.stepgen.00.enable               x-enablehm2_7c80.0.stepgen.00.position-cmd         not usehm2_7c80.0.stepgen.00.position-fb          x-pos-fbhm2_7c80.0.stepgen.00.position-reset       not usehm2_7c80.0.stepgen.00.velocity-cmd         x-outputhm2_7c80.0.stepgen.00.velocity-fb                  not use

Trying to configuration with xyzac-trt.ini and xyzac-trt_cmd.hal. without any success on it.
can someone help give some extra info. get the axis moving. 

thanks for your time.
 


 

hey Giovanni

did you use virtual box for your VM

i am about to try your guide again using virtual box and a stock standard linuxcnc iso 2.93 install

just thinking i could just grab your vm file and work back from there if you used virtual box

cheers
