Hello friends
this my new CNC plotter machine based on GRBL firmware which supports Z axis servo
In this video i will show you complete guide how to make mini GRBL based CNC plotter powered by two 28BYJ-48 Stepper motor & one tower pro mini servo

Also how to do calibration of axis and speed test is shown in this video

Main body of the machine is 3D printed

More detail

Special features
1. GRBL support for Z axis servo
2. Big print area (100 X 100 mm)
3. 3d printed parts
4. Easy gcode making process

Component required:

X & Y axis rails :- Bike spoke wire 2.75 mm dia

Arduino UNO :- amzn.to/2iVQL3s

28BYJ-48 stepper motor :- amzn.to/2iUUvC5

I had a problem of ordering pcbs ,now because of your help it is easy for me to make pcb

I wanted to let you know I built this machine and it works really well. I 3d printed parts that I designed after looking at how you built yours. I had to reinforce the parts that held the motors a bit as the shaft was not at 90 degrees because of belt tension. I ran it in half step mode which helped a lot because my table is only 100 mm x 100 mm. I am really happy with those motors as they work better than expected. Thanks, you provided everything that was needed.

I love this! Excellent job, thank you.

Thanks. Very elegant and cheap. A detail: the backlash, we can see it on the corners. To eliminate it it's quite easy: one can suspend a light weight to the axis with a wrapped string. You have now a perfect and precise device. Thanks.

Thank you for presenting such an excellent video. The audio of your voice was a low in volume but an amazing thorough video. Owen Vinall from Down Under Australia.

Hi, Thanks for your fruitful tutorial. Actually, my both motors rotate in the only clockwise direction. While I have anti direction too but motor rotates only in 1 direction.

I would suggest using basically any other stepper motor though. 28BYJ-48 contain a large number of plastic gears that result in tiny inaccuracies that build up over time. That's likely what's causing the slight inaccuracies in the circles. But really nice build!

Very helpful videos to me ... thanks for give us such kind of videos
@Nani-wu5iy 6 years ago

This one is soo good please try to replace those 3d parts with another one as everyone won't have 3D printers.And make the video more in detail.. Thank you.. All your CNC videos are very good keep going..👍

awesome project and i can easily run it..

I believe you can remove the jumpers or leave just one to have half step, those motors already has a large gear box inside, you dont need microstepping here, then you may get higher speeds as the GRBL has a clock limitation in the pulses per second for the motor step.
