GRBL-Plotter tangential knife

- GRBL-Plotter can now handle a tangential knife on axis A,B,C or Z.
- If Z is used, knife can be lifted with servo, using e.g. 'grbl_v1.1f_Servo.hex'
- 360 units/turn slows down everything - can be reduced to custom value (only usefull if gcode will be generated by graphics import).

Very Nice work on the Cutting head
Ok, gracias no había visto ese documento muy amable por su atención
This is perfect.
Good jobe inlike this vedio tank you frend
Very nice and horrifying at the same time!
yes, the built is not rigid enough to use a knife. For a laser it is ok

Great. What board do you use to have a rotating Z axis?
It is a selfmade Arduino CNC shield - just 3 axis: svenhb.bplaced.net/?CNC___XYZ_Einheit
Thank you for the video , I'm asking wich tool used in this video to get G-Code for rotary axes Thank you
GRBL-PLotter converts DXF, SVG or HPGL into G-Code with the option to generate the tangential axis command. In the video the Z-axis was selected for tangential to use a common xyz-setup. Up/Down was done with a servo using the spindle on/off signal.
I will try to modify my 3D printer in such a way that Extruder Step Motor is the Tangental Axis. Do you think it is possible?
podras explicar mas detalladamente como configurar grbl plotter para uso de cuchilla tangencial. gracias
muy buenos videos
I hope this instruction is ok:
grbl-plotter.de/index.php?id=tangential-knife
I have modified my 3D printer (Artillery Genius Pro) as a tangential knife. E (extruder) motor is now my tangential axis. How can I get the program and use it?
You get the program here: github.com/svenhb/GRBL-Plotter
More info you find here: grbl-plotter.de/index.php?id=form-setup-1#path-modifications
If you use Marlin, I recommend to change to grbl firmware - if possible.
Hi ! What type of stepper motor did you use ?
It's a stepper motor size "NEMA 11"
Hi GRBL, I'd like to know if the Limit Switches in your Software is applicable? Thank you so much.
I forward the grbl status Input Pin State:: github.com/gnea/grbl/wiki/Grbl-v1.1-Interface#real-time-status-reports
@@grbl-plotter Hi thanks, I'm having a hard time calibrating the Z Axis which is the Tangential. However do you know how to calibrate the Nema 17 for the Z Axis?
@@147justine Did you check this: grbl-plotter.de/index.php?id=tangential-knife-1 and this grbl-plotter.de/index.php?id=tangential-knife&setlang=en ?
Copied from below: Instead of step/mm I assume step/1° $102 = 200/360 = 0,555555. Then you need to use 360 for "Units per turn": grbl-plotter.de/index.php?id=tangential-knife#example2
Or you try example and set $102 = 200/3.6 = 55.55555 with "Units per turn" = 3.6
If you use stepper driver with 1/2; 1/4, 1/8 step, you need to multiply the $102 number by 2, 4, or 8....
Kann man auch anstatt einen Servo auch einen Schrittmotor verwenden? Wenn ja was muss man anpassen? Ich habe bereits eine CNC den MPCNC dies wird mit der Ramps1.4 gesteuert kann ich das auch damit umsetzten?
Ja, dann wäre das die Z-Achse und die Messer-Drehbewegung wird mit der 4ten Achse (z.B. "A") umgesetzt.
What value Step/mm for Z axis should I have to set?
I using stepper motor 200 Steps per 360 degree turn.
Instead of step/mm I assume step/1° $102 = 200/360 = 0,555555. Then you need to use 360 for "Units per turn": grbl-plotter.de/index.php?id=tangential-knife#example2
Or you try example and set $102 = 200/3.6 = 55.55555 with "Units per turn" = 3.6
This we have to write the program manually if I am correct. What to do for getting the program with grbl ??
Can I use Stepper motor instead of Servo motor for up and down? I'm using Ramps 1.4 right now and I'd like to have 4 Axis Which is X, Y, Z = For Tangential , A= For Up and Down.
Yes, as you wrote: just select "A" for the tangential axis.
@@grbl-plotter Hi, I just do what you say but should I configure the firmware in order to make it work? Because the A-axis doesn't move (Extrusion) and I use the firmware of Grbl using the Xloader which is in Hex.
Sorry I'm new at CNC and I'd love to complete this Project. I hope you can help me.
@@clipsme4248 I took the default configuration from here, perhaps you need a different pinout? github.com/fra589/grbl-Mega-5X
Is manual control of the A axis possible via the joystick? Perhaps this axis has a different name - like "E"?
@@grbl-plotter Hi Sir, where can I contact you? I need your help. I'm almost done with this project.
hi, will this work for the 3018 pro CNC?
If you can build such a knife holder, it should work. Either you can add a fourth axis for tangential, or you use Z for tangential and add a servo to lift the knife (then you need a controller which can control a servo).
I used a special grbl-version which creates PWM signal specially for rc-servo, than for spindle control.
@@grbl-plotter Big thanks for answer, little bit hard for me at this moment, will try plotter knife first, than that variant.
Hi i'm interested in this tangential knife g-code generator
It's open source, just check here: github.com/svenhb/GRBL-Plotter
@@grbl-plotter Thanks for the link
Hola buenas noches, el grbl para controlar un servo de un cnc pen ploter, cual serviria, gracias
Check here: grbl-plotter.de/index.php?id=quick-guide
For Arduino Uno I recommend github.com/cprezzi/grbl-servo
But you could also use a converter spindle-PWM to servo-PWM: github.com/svenhb/Plotter-ServoControl
@@grbl-plotter muchas gracias por la información,voy a revisar
Hay algo que no entiendo, "The CNC shield V3 for Arduino Uno was designed for grbl 0.9. Because of a change in the pin-out in grbl version 1.1 (pin 11 and 12 are swapped), the spindle-pwm signal can be found on the Z+ pin. Check schematic", hay que intercambiar el pin z+ a z-?? en el control del servo@@grbl-plotter
@@aos1611after checking schematic and layout I would say Z+ = Z- both signals are connected.
gracias, @@grbl-plotter
como conecto el motor nema se conecta a la tarjeta arduino o es por USB alguien que me explique por favor
The tangential motor is the Z axis: grbl-plotter.de/index.php?id=tangential-knife&setlang=en
Hi sir, How are you, u made nice application.
i am not able to use tangential axis please help me, thanks.
hi, may i help you to design a better program. For my idea the program is not finished. I missing features and places what where to most to by done. The program is for example to match a color circus . i missing a feature to select/ reload/delete a loaded image from the canvas and to close a loaded image/file. make and good preferences opportunety with a clear explanation what doing what. It is a litte bit a pitty and shame how to the program now is because in potential it is a good program. Only is unclear what doing what and where doing what. For example bright colors in the interface scares people of . design a better graphical splashscreen. people take the than program more seriously. Make a good video tutorial how the program works and you must use and setup the program. Make your email account available on your your youtube canal and on you website.. again sayed the program has some potential but need some tweaks to make it a better program.
Feel free to open an issue here and ask for new features: github.com/svenhb/GRBL-Plotter/issues
Bro can u please help me
I am doing same to same similar project
