help please how can i configure gbrl to have a pen up and down for my pen cnc #1279

Closed oraherb closed 5 years ago

oraherb commented 5 years ago

hi guys can someone help me how to configure this grbl (https://github.com/bdring/Grbl_Pen_Servo) to work with my servo for up and down movement? im using windows 10 and ugs my hardware is arduino nano and i connect the orange wire or pulse of the servo to pin D11 on arduino how can i make it work to have a pen type cnc i follow all the instruction from here (https://www.instructables.com/id/How-to-Control-a-Servo-Using-GRBL/)but nothing work my question is what D pin should i use to make the servo up and down and how to rewrite the gcode to trigger the servo for up and down pleasese help i been figuring out this on my on and now im already giving up for my project please help

svenhb commented 5 years ago

I used https://github.com/cprezzi/grbl-servo Just send Sx for spindle PWM to control a servo - x between 0 and 1000 Short description in german for an egg-bot with servo (but with link to google translator): http://svenhb.bplaced.net/?CNC___Eggbot___Eggbot_via_GRBL-Plotter

@svenhb bro so i have to change the gcode to trigger the servo for pen up and down? what will i insert to the gcode?

svenhb commented 5 years ago

Yes, for example send "M3 S50" for pen down and "M3 S500" for pen up (or M4). The correct values for S you need to figure out. If the servo need some time for motion you may add the command "G4 P1" after pen down/up command for 1 second delay

oraherb commented 5 years ago

@svenh bro thanks but how can i figure out the correct value for my S?? and it gives me an error so whats wrong i follow the instruction in your website please help me bro

Screenshot (6)_1 heres my error bro @svenhb

svenhb commented 5 years ago

You send M17 and M18, this commands are not known by grbl, and also not known for other CNC - check known M-Codes here: http://linuxcnc.org/docs/html/gcode/m-code.html

How do you generate your GCode?

oraherb commented 5 years ago

@svenhb in inkscape and it has an unicorn plugin bro

svenhb commented 5 years ago

You may save your inkscape path and open it in GRBL-Plotter... But here we are in the Universal-G-Code-Sender area...

@sve Screenshot (8)_1 how can i generate gcode for my pen plotter bro? nhb

svenhb commented 5 years ago

Drag your SVG and drop it on the 2D view In Setup section you define what to do at pen up/down action

oraherb commented 5 years ago

@svenhb ok i will try it thanks hope it works just a sec...

oraherb commented 5 years ago

@svenhb bro your awesome but i have a problem where should i define the pen up and down action i cannot find it where to write the code for pen example (m3 s50 Screenshot (10) )

svenhb commented 5 years ago

In setup - graphics import - GCode generation, on the far right, enable Servo control. Via Main GUI "Control/Jogging" you need to switch off / on the spindel with different speed, to find your S-Values for up and down. image

oraherb commented 5 years ago

@svenhb bro i subscribe to your youtube and you make a dvd plotter thats what im doing now and thanks it works but the servo for pen is traveling to far like 180degrees can u give me the exact setting of your dvd mini plotter ?

svenhb commented 5 years ago

My dvd plotter uses stepper motor for Z, but the egg-bot I use a servo: 100 for pen up, 400 for pen down

oraherb commented 5 years ago

@svenhb bro it works but how can i setup my mini pen plotter its x and y axis travel too far my range is only 40mm even i configure in grbl setting?? im using DRV8825 step driver do i have to connect the M0 M1 M2 to +5v like a4988 to have a mircro stepping? if not how can i make this mini cnc draw small image?? CYMERA_20191007_014035_1

svenhb commented 5 years ago

If you move by 10 mm via virtual joystick, does it travel 10 mm? Then it's ok. You can resize your drawing, depending on source a) SVG during conversion, b) via menu 'GCode transform. If you have an image you need to define the size on the tab 'image correction'. Most probably your grbl settings are not correct. I set M0,1,2 al to +5V GRBL-Settings: $100=107.000 $101=107.000 $102=107.000 $110=10000.000 $111=10000.000 $112=10000.000 $120=500.000 $121=500.000 $122=500.000 See also http://svenhb.bplaced.net/?CNC___Mini_CNC_Plotter

@svenhb bro can u give me idea how to make an gcode that will fit in my mini cnc from dvd i mean i tried everything but the gcode i created always exceed the limit of my mini cnc 30mm my stepper x and y always running out of axis

svenhb commented 5 years ago

Does your x axis move by 5 mm if you send x5 ? Or if you click on '5' in virtual joystick?

oraherb commented 5 years ago

i tried those setting and it move 9mm when i press 5 in virtual joystick

X-axis: Engine = 400 = steps / revolution = 1,111 steps / degree setting the Y parameters: $ 100 = 1,111; $ 110 = 10000 (max. Speed - tried); $ 120 = 500 (max. Acceleration -ausprobiert) Y-axis: Engine = 400 = steps / revolution + reduction 1:50 = 20,000 steps / revolution = 55.555 steps / degree setting the X-parameters: $ 101 = 55,555; $ 111 = 800 (max. Speed - tried); $ 121 = 500 (max acceleration -. Tried)

oraherb commented 5 years ago

when i tried this your setting theng press 5 in virtual joystick it move 1mm per jog

$100=107.000 $101=107.000 $102=107.000 $110=10000.000 $111=10000.000 $112=10000.000 $120=500.000 $121=500.000 $122=500.000

svenhb commented 5 years ago

Aha. You may change $100 to 1.111/95 = 0.617 and $101 to 30.86.... (or the other way arround 9/5) Makes no sense to change any graphics scaling when your hardware reacts wrong! BTW: did you uncheck "STOP Jogging on mouse up" - then on click causes one complete move for e.g. 5 mm.

oraherb commented 5 years ago

@svenhb hey bro when ipress the Y axis it also move the X axis in virtual joystick but when i press the X it doesnt move the way what u think bro??

svenhb commented 5 years ago

Check the COM window to see what was sent to grbl. Are you using the hardware which is mentioned in your grbl-link (https://github.com/bdring/Grbl_Pen_Servo) ? Perhaps some signal-wires are mixed up?

Default setup. The default setup is for a buildlog.net Pen/Laser Bot Controller. If you are not using that, you need to make sure your schematic matches the pin defined in cpu_map.h

oraherb commented 5 years ago

yes bro im using this grbl (https://github.com/bdring/Grbl_Pen_Servo) i try it in UGS well its perfect bro its calibrated and i change setting its work fine now but in the grbl plotter it doesnt work i mean when i press 5 in virtual joystick its go 7mm in actual

svenhb commented 5 years ago

If you move 5 mm in UGS, does your hardware move by 5 mm? I think you need to play with your $100 / $101 setup.

oraherb commented 5 years ago

yes bro it accurately move 5mm if i move 5mm in ugs

oraherb commented 5 years ago

@svenhb hey bro help me with this how can i generate and gcode image that size is 10mm height and 10mm width i dont know how i can resize this image to make it fit with my minimum axis Screenshot (10)_1

svenhb commented 5 years ago

Go to the tab 'Image correction' and play with 'width' and 'height'

oraherb commented 5 years ago

ok bro thanks
