I love that bearing holding the pen from wobbling. Excelent. It looks like it is hitting something that it does not need to on each down stroke and that is causing some unwanted noise. Lots of clicking that does not have to be there. Other than that, pretty nice. Really nice and straight lines with no flex in the pen. That is just outstanding.
your presentation is very inspiring, I'm so lucky to be here to see this amazing stuff I've been researching but maybe because of my self-study I don't have a solid background, I want to ask you a few questions. : 1/ i use arduino uno and cnc shield v3 to connect grbl , nema 17 stepper motor and a4988 ( or drv 8825 ) and apply microstepping step mode , then to get the real highest speed , acceleration and accuracy Depends on what? do i have to tweak the arduino's code, or simply tweak the numbers in grbl to the highest, because i have referenced many other videos and they use the same gadgets as me, but they hit the highest point of the speed and accuracy , do you know why they hit such a threshold ( you , for example ) I look forward to hearing from you
Thx! :) No need to change the Arduino code, just optimize the GRBL settings. I think it is very important to choose a good stepper motor. What I used: JapanServo KH42JM... We have a lot of these used, 4-8 Euro/pc. A very small gear ratio is required, here 360 degrees = 40-42mm pen movement, on the X and Y axis. This allows it to be fast and still accurate for drawing work. Due to the fast movement, the torque is small, so there are 1 motor each at the ends of the belt, 2 motors in parallel for the X axis and 2 motors for the Y axis. 4 in total, plus 1 on the Z axis. Move a small mass in the Z axis, a small motor, make the moving mass light and perform as much Z movement as possible. I only have approx. The Z stepper moves 45-80 degrees. This is basic. After that, the values must be optimized in GRBL. (speed, acceleration...etc.). Microsteps should also be experimented with. The operating voltage was optimal for me between 14-18V. The motors should receive enough current that they can heat up, but not be hot. (max. 50-60 Celsius)
Thx! spring is preloaded so it doesn’t have to be very accurate. Upper dead center approx. 2mm, the bottom is about -1mm. If that’s what you wanted to ask. :)
Sir I'm using 2xNema 17 steppers and a servo (for pen) in my cnc plotter. Using the same cnc shield but my servo isn't moving. Can you help me with this? Also, tell me is there a way to get in contact with you? It would be a great help!
Kösz! :) Igazából csak egy tákolmány, a működésére voltam kiváncsi, na meg arra, mi is ez a cnc vezérlés. Inkább csak kisérlet volt, de sokat tanultam belőle. Igen, itt még A4988-as van a pajzsban, de később DRV-re váltottam, de nagy különbséget nem tapasztaltam.
Magam is szeretnék egyet építeni, s ez az az út, amin én is elundultam. A sebesség fontos lesz, s gondolom, ez a driver teszi a dolgát! Jól látom, a szíjakat feszíted valamivel? Csúszás/elmozdulás előfordul?
Dire Strait Nice! Good job with cnc
Wow. Love how you got the thing to plot at such a high speed! Very impressive! Nice Pen lifting mechanism!
Самый быстрый cnc на диком западе
A cam and lobe on the z axis! Nice! Why didn't I think of that? And Dire Straits too...excellent touch.
LOLsounds like a tap dance and some voice sounds..band way in back
Hello . CNC very nice. I was a nuisance. Please contact me
How to get that fast?
Классная скорость.
Awesome results! Thanks for share! I will try to make a CNC Arduino based like yours. If change the pen for a blade, can cut shapes in same way?
Wow, nicely done love it! Busy collecting material for my build, received the Arduino CNC shield and drivers yesterday.

great work. what kind of belt and stepper motor do you use?
best regards

hola men una pregunta como iso el braso del lapicero
exactamente.
how to get it slider please tell
hello my friend..very nice video.in the axis that raises the pen you have given a specific value for how high-low it will travel distance?
Thx!
spring is preloaded so it doesn’t have to be very accurate. Upper dead center approx. 2mm, the bottom is about -1mm.
If that’s what you wanted to ask. :)
precisão e rapidez, parabéns que programa usou para gera o códigoG para grbl
how do you make axits z fast ?

Upload files in arduino through: robottini/grbl-servo It worked for me.
What program do you use to make the images you print
how ro you make g code
servo?
great work !!!!
muy bueno migo. like
Your machine is awesome
3 driver so 1 driver isn't working, right?
WOW, that's fast!
Какой мотор стоит на оси Z ? Если сервомотор то как он не разваливается?
Normal, 2 phase (4wires) little stepper.
whistle194 - Where can I download this vector with a locomotive? Is possible to send me this file to mail? Great ploter... great speed :-)

Wooow very fast reply :-) thanks.
Thanks !!! whistle194 I`m using LaserGRBL but it not read dxf files. What program You use for drawing?
Tutorial pls
How you make gcode for this cnc ?
Nice the cnc on steroids 😂

Szia Whistle194!
A drivereid nem A4988-asak? Vagy valami korábbi verziót használsz? Nagyon tetszik a munkád! :)
Kösz! :)
