Terrific explanation for us beginners.. This is the type of teaching we beginners need. It is beyond frustrating to watch videos that skip steps assuming we know anything about cnc operation. Showing each area to mouse click on is great. I am a college graduate in a very tough medical degree and cnc operation is testing my brain to the nth degree. I appreciate your teaching method.
Thanks for the vid series. Perhaps some paper on the wood, then lowering the tool to leave a mark at the start and finish of the moves would increase accuracy.
The math is really quite easy. Distance actually traveled divided by the distance it should travel gives a ratio ; 107.5 / 100 = 1.075:1 .... Look up the currently set steps (860). Divide steps by the previously calculated ratio ; 860 / 1.075 = 800. Reset steps to 800. Done.
Or you could say 1 full rotation of the screw is 8 mm and there are 200 steps per rotation and because settings say 800 that mean he's using quarter steps. So 8 mm divided by 800 equals .01 mm per quarter step.🙂🙃🙂🙃🙂
In my experience the only time you need to adjust steps per mm is when you have changed stepper motor angle type, stepper controllers that have a different micro stepping defualt or lead screw pitch. These machine are simply incapable of the level of sub thou accuracy that would ever need compensation due to say thermal expansion, I saw your previous video where your pocket was incorrectly sized, but that was because you did not set the tool width compensation value. It was not a steps per mm issue.
Awesome video, I appreciate for this explanation, I have the same machine, with the same size moving base plate, my engraver bit moves in X axis for entire length but in Y axis only 120 mm, please can I use the same concept to expand the Y axis size ? Because my project size requires 160 mm in Y axis. Which number for Y axis needs to increase? Thanks very much for your help.😊🙏
Hi. Roger Enjoy your videos .I have trouble with my new 3018 Pro. I hit send & the spindle goes all the way to top chatters against the stop then starts to move around like it was cutting. Anybody please HELP thank you
Hi Jerry, Google, GRBL $ code list www.diymachining.com/downloads/GRBL_Settings_Pocket_Guide_Rev_B.pdf You could put in $3=6 this will change the axis direction
@@rogerwebb9600 Thank you Roger for the response BUT now all the spindle assembly does is drive the bit down in to the material until it stops the motor.
Can anyone tell me why my z axis wants to go beyond it's stopping points and start thudding like trying to go further. And, if I set the zero point with the button it doesn't recognize it and buries the bit everytime? Help please.
@@rogerwebb9600 thankyou mate my 3018 has been sitting almost 1.5 years as i could not get the driver to run on Windows 10. But now its up and running again, i would love to know if you think i could make a coin mold from graphite with the 3018. Graphite is very soft i could send you a sample if you like
Hi Jesse, the 3018 may, my 6040 and 6012 CNC router will and my Sieg X2 mini CNC will in 4140 steal, I have videos of them doing this job on my channel.
Hi Roger and anyone who can help me, the commands of my CNC 3018 no longer respond. Use of Grbl Control standart software. here is the message that the CNC sends me: [CTRL + X] SERIAL PORTE ERROR1: NO SUCH FILE OR DIRECTORY. What could be the problem and the remedy? please help me! thanks in advance
No, No Roger, that's fuzzy logic........I just can''t do it.....with Mach 3 you specify the move and the axis to move.......G00 to rapid to X00 ,Y00 (G54) etc and G01 to feed to X50 Y50 etc, add a bit of Z to go down......that is so logical I write my own G code and I'm an 80 year old noob at best. It's only 2.5D but what the heck, you can write that manually so easy......3D needs a CAM solution. If I indulge in one of these toys.....they're all toys now I'm retired.....I'll have to redo the op system to run with Mach3 and a Gecko drive....whatever...hang the cost.

Thanks Rodger huge help to be honest
Thanks. Beautifully explained
My pleasure

Awesome I wanted you to do a video about this very machine and wow....you did....Thank you.
Thank you Roger!
Thank you Sir!
You are welcome!

yes answer is integer number. if its 798.978 or 801.213 then you need change leadskrew better cheap chinese version that have not pitch error xD
Thank you soooooooo much :-)
You're welcome!
I have a problem with program it on my computer I still haven't got it going is there a special computer for that

@@rogerwebb9600 Hi dear any answer to my question?
Yes you can. It is the same method using a different axis number
bonjours pourriez vous me dire comment peut 'on accélère la broche quand elle grave . La mienne avance pas vite du tous
You can do this in the GRBL control
@@rogerwebb9600 Merci j'i suis arriver enfin .
Valuable content! I would however suggest to use a on body mic instead of a room mic in the future.
