To all users as of 12/2020.... You DO NOT get a warning if you don't click "Zero" @ 5:43 and it WILL plunge the bit right into your stock. Ask me how I know. When you click it, you will see the values change so that they are relative to the zero Z position, this is why you run the probe: to give the autolevel a new reference point.
Hello, and thank you for video, what is the reason after auto level to return to center of your work? is that the reference that you normally use, or are you able to record those values at x=0 y=0 as a starting point? thank you
@@mendebil i read on article with grbl doesnt suporte m6 comando for Tool change, need creat an macro to run, u van recommend me an board and firmware to use ?
@@GGJP200 keep a reference point outside the work piece. After 6 years I am still on a $3 Arduino uno and $2.5 CNC shield V3. This is an amazing setup worked 8h in a row without losing a step
@@mendebil i have the same setup using bcnc but with cnc shield v2, i have an auto leveler and an fixed probe , that fixed probe i wanna use to auto zero tool when switch tool on toolpath, but the grbl have issues with auto zero tool, but its still fine to work hard, bcnc is very good interface, its liltle hard for 0 experience, but good for learn, thx for reply mendbil
i know this is old, but the probe pin is SCL on the arduino, i actually built a schmitt trigger circuit for all of my limits and probe to overcome electrical noise.
autolevel mémorise chaque hauteur dans chaque carré OU il détermine une hauteur moyenne sur l'ensemble des carrés ? Google traduction : autolevel remembers each height in each square OR does it determine an average height over all of the squares?
Good afternoon. I have managed to run the program thanks to its tutorial and I was able to make a pcb, but I have doubts to change the milling tool and put a bit, so that the machine respects the height and makes the drills correctly. Is there any adjustment to take into account when we are going to change the drill for another drill ?. Thank you.
Hi. For tool changes memorize the coordinates of the initial zero stage (at 4:40) and use the same to probe and zero out the new tool. Provided that the height in that point (in my example x=1, y=-6.5) has remained unchanged, the height map will be valid for the new tool as well. Now keep up the good work!
GOOD DAY ,i am a beginner and building my first CNC , i am having problem of locating the Pin that you assigner for the auto-level probing ,i hope that it is not so much to show me the location of the pin and the 100 nano farad capacitor , your link was not that clear for me. regards
Can you explain why when you did the final Z zero probe, you inverted the sign of the pre-set zero value? (You put -1 in the probe Z box, but the WPos Z is 1.0, not -1.0. But for X and Y, you did not flip the sign.)
yes. probing is a 3 axis move. x and y are the current position because you want the router to probe vertically only. I scanned z until -1, but the probe triggered at -0.01. keep it up!
Hello Friend I have never used bCNC and am a little disoriented. I am using GRBL 0.8 and Shield V3, but I do not know how the probe is configured, nor where it is connected. You can help me?. Thank you
Hi there. No reason not to upgrade to 0.9! probing is native on 0.9, not supported on 0.8 as far as I know. Connect SCL to surface (top right corner on board) and GND to your bit / end mill
The documentation on the wiki for probing in bCNC software is sorely lacking. There are still parts of it I can't figure out what they do. The autolevel took me a while and I was only able to figure out how it works by trial and error. Lots and lots of trial and error. I can set that up and run it in my sleep now. Maybe I should write the procedure down and take some screenshots and photos of the mill and make the documentation myself. At least then the next guy won't think they completely suck at google searching. Or that they should have learned how autolevel works in the 5th grade like everyone else.
I have a DIY laser printer capable of cutting 3mm MDF, as a probe I use a microswitch and to home the Z axis I use soft homing (I move the Z axis all down until it bottoms out, the move to the top), so the top is at "0", when I press the Scan on bCNC, it tries to move the Z axis 3mm above 0, which is impossible, I ended up with the GRBL throwing an alarm code and it donesn't work. I got it working by adding "safe.0 = 0.0" to the config file under the "Stock" section. Hope this helps someone! Also, thanks for the vid! Tried UGS, it works, but it removes all the commands that makes my laser work from the GCODE (it still experimental).
It took me 5 days 20 hours total to design this machine. and 3 more months to fix the mistakes :) my advice is just keep it simple and use as few custom parts as possible. After all these yrears all I can say it's amazing this thing was functional at all, not to mention getting useful parts from it at the end of the day haha
Thank you!! The best video about bCNC Autolevel! My work is doing great thanks you. Regards from Brazil.
:) brazil and Romania used to be in top 3 fastest internet connection worldwide. Cheers friend. we related in more than one way. nao e brinquedo nao!

Happened to me actually :)) and they are pretty strong bits if you have a good transmission you might damage your spindle
Happy New Year to all pedal builders!!!! And remember to take a bath. That's how Archimedes discovered displacement

No that was just to give a better view of the work. You can hit start after auto level is done
@@mendebil thanks brother, i figured it out, works rather well!
awesome,
Hi, u know if with Grbl 1.1 i can use Auto Zero Tool ? on Bcnc ?
Good question. I have been considering an upgrade, but I don't like the new grbl interface so I don't know

Hello, great work! I would like to know what engraving tool are you using? What size and where did you find it? thank you.
Good morning, do you use as a grbl milling machine driver for arduino? How (to which pins) should the sampling wires be connected?
i have the very same question right now, did you found something?
i know this is old, but the probe pin is SCL on the arduino, i actually built a schmitt trigger circuit for all of my limits and probe to overcome electrical noise.
Thanks for the excellent tutorial but where do you solder the 100 nano farad capacitor?
between SCL and GND top right! 3.bp.blogspot.com/--IVqD3gm-oQ/VSFeoZkZHvI/AAAAAAAAPpA/wvwOe2GNjgM/s1600/ciclop%2Bscanner%2Bwiring%2Bdiagram.jpg

It averages the heightmap based on the known coordinates. That means it treats it as a bumpy surface not a flat one!

Buna nu stiu de ce nu merge da numai Probe fail nu sti oare de ce mersi
problema e electrica pe arduino cel mai probabil
Contactele verificati si condensator de filtru musai sa lipiti
Ne place ce faci! ☺️ Ești din București?
București :) Mersi
