How to Set Up and Calibrate an Axis on Any CNC Machine 

Great Video!! Sincerely appreciate the simple explanation

Thanks great video tutorial

hi great video! your video and tool and how to is really helpful, before I learned from you and cal it, my 3018 cnc move "10mm" but actually just 4mm ...now it can move 20cm out of 20cm, not a half mm distance error!

@xix xeaon, you can always use calibration test blocks (usually used for ultrasonic thickness meters and linearity checks) for checking accuracy of your cheap digital caliper

question for you, I had a woodpecker control board that was replaced with a new Chinese board with 340 driver. The axis are off by a ratio of 4 to 1. I could correct by making the $101= 3600, but that sounds so far off; that I wonder if there could be another issue.

thanks

Sangat membantu,,

Great video, Thanks. BTW aluminum IS conductive, your bed probably has a coating on it.

Hello, I have a question, I am new with the cnc3018, when I put it to work with the lasser the machine only moves linear. but when I put it to work with the router motor, the motor rises and writes over the air. I have even changed my mother board but it still doesn't work for me. Please can you guide me? I used candle and laserGRBL.

Amazing, we can do that too with the end stops? I guess the answer is yes

Hi. Can you help please. After I load G-code in to machine (Example G-code X=1" But the machine only move .250 ". Can you help how to set up the machine move as the same value as the G-code . Thanks you very much!

I completely replaced the screw with another one with a different thread. and the problems began. in cnc 3018 in x-axis

Nice video. Is it possible to check the surface flatness to ensure the carriage is parallel with the table?

In the second method where did you connect the led wires. I have watched the video several times but don't know the steps followed after sanding the bed

Man: It's 145mm across. German: It's 144.586779048801mm across. American: it's a foot minus a hand and 4/567 over about a toe across.

Wonderful stuff. But if we use belt instead leadscrew? How to proceed then?

Thanks sir can you help to make CNC machine

Hi. I am doing this for a CNC 3018. Do you know if these use the same stepper motors?

Do I do this on all axis or just the X axis? Great video Thanks in advance :)

And why in the second method you type $101=... different from first method? Is that refereeing to Y axis? I means 100=X axis and 101=Y axis?

how do we change the micro stepping?

5:15 and i allready see this introduce backlash. you will measure other side moving back. you need move one direction 800 step is correct.i giveup if it backlash it should be more than 800 step so your cheap chinese thread have pitch error

Sir hindi me video bana sakte ho kya

800 steps sound fine,but when it go 799.98 or 800.02 then something is wrong. it cant be. 2:40 LOL controlled think it go. LOL it moved 140mm if you tolded it.and anyways you moved one direction then other direction .there HAVE to be backlash.move 50mm then continue same direction 50mm. ihave any issues ever.motor steps are 200 it wont change.thread pitch could change if it cheap,but i doubt dat.backlash i beleave LOL but controll not think it go this much.it allways move that much you told,but you see it moved wrong. not opposite LOL ok got it. you moved based on RULER by hand 140mm (backlash included) yes it actually moved less.its back lash.dont calibrate your machine based on backlash. fix back last 800 is only correct based on math. if you are moving 10mm 10mm 10mm 10mm same direction your machine now actually move 10+.something. be couse you calibrate machine with backlash. you have backlash spring?? lol.you think it works?

3:46 nooh! use dial and you see your calibrated machine moves more now. you did not believe 800 is correct

0.003mm = 0.1thou ??? 25.4mm = 1inch! 0.003mm/25.4 = 0.00011811024inch

can I just say ,You used a Ruler and not a Rule, a ruler is not accurate . but a Rule is, so you will always be out of measurement if using a ruler, Please learn the difference from a ruler to a Rule. Quick Hint, A ruler is a none calibrated measurement of an item, A rule is a calibrated machine tool. As for using the bed to use as a sensor, I would Not, Aluminium oxidizes and so you will get in accurate measurement's after a day, so unless you keep sanding the same area clean to get the contact for the voltage to read, you will end up with a worn area, Hint Buy a proper probe, they are very cheap. at about 4 bucks Always keep your work clean, use an extractor , or a simple vacuum cleaner. By keeping the work part clean helps reduce friction and heat to the part, Simples. Personally I would avoid doing anything in this video. and seek proper learning tuts.
