Hi
I need help to control the shield in the title. I'm doing a cnc with dvd stepper motors using grbl controler, but when i charge a Gcode file to try it the motors spin in one direction almost for ever. the cables of the stepper are connected correctly.
I also want to use an I2C lcd display in that shield (in has 4 pins for that kind of display). the problem is that when i connect it it just turn on but without showing any kind of info, just white rectangles.
IF YOU NEED IMAGES CHECK THIS: MEGA
ps: Where can i connect the extrudor?
Ps: If you can send me what to do with the empty pins in the shield it will be great
please help
Do you mean the Keyestudio "CNC Shield V4.0"?

If the motors are not spinning the right amount, you may have to change the configuration:
You'd have to check the GRBL documentation to see how an LCD might be used. Home · gnea/grbl Wiki · GitHub Off hand I don't think GRBL does LCD output.
I don't think GRBL can control an extruder. It claims to be "An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino". A milling machine, router, or engraver don't have an extruder with temperature and speed control so 3D printers typically use an Arduino MEGA 2560 with a RAMPS board to control three steppers and two extruders.
hola. perdon, sé que no tiene que ver mucho con el tema, pero en el caso de la placa sí. tengo la misma placa controladora y queria saber :
1: si alguien sabe como se conecta y se usa el bluetooth. tiene conector bluetooth, le conecté el hc-06, pero no puedo hacerlo funcionar.
2: si alguien sabe como y donde se conecta el laser. tengo un laser de 500mw, y otro de 1000mw, de 2 cables y no se como y dnd se conectan.
alguna informacion sobre eso?

Hi. sorry, I know it has nothing to do with the subject, but in the case of the plaque it does. I have the same controller board and wanted to know:
1: if someone knows how to connect and use bluetooth. It has bluetooth connector, I connected the HC-06, but I can not make it work.
2: if someone knows how and where the laser is connected. I have a 500mw, and a 1000mw, 2-wire laser and I don't know how and where they connect. Any information on that?
1: Probably to where GRBL gets serial input. Probably RX/TX on Pin 0 and Pin 1.
2: Probably on the pin used to control a milling machine "spindle". Check the wiki.
ah, ok, gracias. si, busque en wiki y no veo las conexiones. no dice en ningun lado donde se conecta el laser o husillo. bueno, gracias igual. seguiré buscando
