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.

'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.

Hi.!!
Aciera, Thanks.
I did what you recommend me but I can make the B axis to move or get home.
also tried to emulate a 5 axis gcode but I didn't works.
my lack of knowledge couldn't make to figure out how to get that issue done.
I tried to the gmoccapy interface.
if there any manual of any info that may help me to figure it out to fix it, I'll love it to hear from you.
thanks for your time.
