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

Yeah, i should gave the details in the previous post. Sorry. 
H-bridge in question is popular module based on two BTS7960B half bridge chips.
As per data sheet:
- PWM up to 25 kHz
- 5 V logic for control is ok
- two inputs for control should be ok: CW PWM and CCW PWM.
- two inputs for CW enable and CCW enable

Looks like i'll need 3 PWM generator pairs (used in mode 2: PWM up, PWM down) to drive 3 motors and i think i can use enable signal from LinuxCNC to drive CW/CCW enable inputs so when machine is off in LinuxCNC motor will be free rotating.

 

There is no error.  It’s informational.  There’s over twenty logs of updating to 001.017 in the update log file.

As I said, expecting handling is present:

github.com/LinuxCNC/linuxcnc/blob/0e1f56...asmac/updater.py#L31

github.com/LinuxCNC/linuxcnc/blob/0e1f56...asmac/updater.py#L42

Nonetheless all of that is irrelevant; something’s up with your installation/OS.  All of the issues you mentioned have been taken care of for some time now.

Clearly there is no error reporting to the screen or to any log. I checked the screeen handler code. My comments about exception handling lacking stand.
