Hello everyone, Firstly, congratulations for the project. I am starting to learn about machinekit and 3D printers so I am noob and maybe my questions will be also noob questions.
A few years ago, I have started learning a bit about machinekit using the documentation and the analyzing the code of the FDM Printer UNI-PRINT-3D (https://github.com/thecooltool/UNI-PRINT-3D) that I executed in a SD image to the BeagleBone Black with all preconfigured (Debian Jessie and machinekit from machinekit.io repositories) and everything was Ok. Now I would like to start again learning more about machinekit so I tried to configure the machinekit-hal in Debian Buster to run a FDM 3D printer example (I am trying to adapt UNI-PRINT-3D) but I have got stuck so I need help to continue. 1-> I have installed the last debian buster image for the BBB with a RT PREEMPT kernel: machinekit@beaglebone:~$ uname -a Linux beaglebone 4.19.94-ti-rt-r68 #1buster SMP PREEMPT RT Thu Sep 16 15:32:36 UTC 2021 armv7l GNU/Linux 2-> I have added the cloudsmith repositories for machinekit, machinekit-hal and emcapplication 3-> I have installed the machinekit-hal and emcapplication packages from repositories (I have tried RIP installation for machinekit-hal but always get stuck at some point) 4-> I have tested that the commands "realtime start/stop" and it works. 5-> I have tested a basic machinekit example: the anddemo example (https://github.com/qtquickvcp/anddemo.git). The example works Ok and changing the REMOTE from 0 to 1 in /etc/machinekit/machinekit.ini I can also connect remotely using the MachinekitClient. 6-> I was trying a more complex example for a 3D FDM printer (the UNI-PRINT-3D because is the only example I have tested before). I don't know if there is a more suitable example but I couldn't find one working in the new machinekit-hal version. 7-> When I try to launch the printer I got this error: ./uni_print_3d.py:2: Unknown command 'import' I paste the all sequence: machinekit@beaglebone:~/UNI-PRINT-3D$ python run.py -e 1 UNI-PRINT-3D.ini loading paralell_cape3.bbio... done starting configserver... done starting linuxcnc... LINUXCNC - 2.9.0~pre0 Machine configuration directory is '/home/machinekit/UNI-PRINT-3D' Machine configuration file is 'startup.ini' done ('halfiles = ', ['uni_print_3d.py', 'touchy.hal']) ('halpaths = ', ['/home/machinekit/UNI-PRINT-3D/uni_print_3d.py']) COORDINATES = XYZ Starting LinuxCNC... rtapi_msgd command: /usr/libexec/machinekit/rtapi_msgd --instance=0 --rtmsglevel=1 --usrmsglevel=1 --debug=1 --halsize=524288 rtapi_app command: /usr/libexec/machinekit/rtapi_app --instance=0 --debug=1 3::2854:rt INFO: Picked default flavor 'rt-preempt' automatically Found file(REL): ./uni_print_3d.py ./uni_print_3d.py:2: Unknown command 'import' Shutting down and cleaning up LinuxCNC... LinuxCNC terminated with an error. You can find more information in the log: /home/machinekit/linuxcnc_debug.txt and /home/machinekit/linuxcnc_print.txt as well as in the output of the shell command 'dmesg' and in the terminal stopping configserver... done machinekit@beaglebone:~/UNI-PRINT-3D$ I do not know why this error appears and how to solve it. Any ideas? Can I not use python HAL? 8-> I have also tried starting from anddemo example that works (not launching linuxcnc) but I got stuck because my installation has not the trajectory planner 'tp' component. Do I have to install more packages? Is there a new trajectory planner in the new machinekit-hal version? I pasted the test: machinekit@beaglebone:~/UNI-PRINT-3D$ realtime start rtapi_msgd command: /usr/libexec/machinekit/rtapi_msgd --instance=0 --rtmsglevel=1 --usrmsglevel=1 --debug=1 --halsize=524288 rtapi_app command: /usr/libexec/machinekit/rtapi_app --instance=0 --debug=1 3::3045:rt INFO: Picked default flavor 'rt-preempt' automatically machinekit@beaglebone:~/UNI-PRINT-3D$ halcmd loadrt tp 1:rtapi_app:3045:user load(tp): tp.so: cannot open shared object file: No such file or directory 1:rtapi_app:3045:user do_load_cmd: tp.so: cannot open shared object file: No such file or directory <commandline>:0: insmod failed, returned -1: do_load_cmd: tp.so: cannot open shared object file: No such file or directory machinekit@beaglebone:~/UNI-PRINT-3D$ Finally, Can I use only machinekit-hal for implementing a FDM 3D Printer? Do you know any example? Or maybe, Do I have to use the old packages from machinekit.io repositories? Sorry for the long post, but after spend a lot of hours reading documentation and testing things I had a lot of questions. Thank you very much in advance. -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
