Hi Mitra,the board you link don't have pins that you can you use directly.So you must program the esp, extract it from socker put in a breadboard adapter, give 3.3v power supply and test the result.With this board you must switch the button and program, re-switch back and test.Bye Renzo

As you can read at the beginning of the instructable you can find all updated material here https://www.mischianti.org/category/tutorial/milling-pcb-tutorial/ .And there, you can find a stecific tutorial about new flatcam with video and examples https://www.mischianti.org/category/tutorial/flatcam-complete-tutorial/ .Bye Renzo

Good work.. Thanks to write Renzo

Sorry no response from muhammadA1065

Check on my site you can find It.

It's just strange to see my library in an article :P.Nice article! Good job!!

Thanks, I used an Arduino as well.To check the 3D printer I was interested in this project https://octoprint.org/.In this card is missing a pin dedicated to serial debugging with Serial1 (I publish update on my site www.mischianti.org soon).In my work in progress, a Solar panel Inverter web centraline( https://www.youtube.com/watch?v=uInRM3YqIv0 )I use a D1 wemos as server REST and Web I have found that the debug pin is really useful when you need of a serial hardware interface.

Hi, if I undestand you want use the same wire for all sensor, but no It isn't possible, with one wire you must use "one wire" per sensor.Bye

The Z axis had interchangeable holder, If I find some time I draw the 52mm holder, but in this period I quite busy.Bye

The maximun size is 10cm x 16cm , but with minimal improvement without altering the rigidiy you can reach 20cm x 16cm.Tthe only think you must do is put a longer rod and move the holder on Y axies, but so the machine It's no more portable.I use wireless and compact size to move It without problem.Bye

Thanks for your support.

Hi, When you open the fritzing file (https://github.com/xreef/grbl/tree/master/resources/fritzing) you can switch to schema view, you must repositioning the elements only.Bye

Hi,If I remember all...Arduino Uno 3€CNC Shield 2€Limit switch 1€Bluetooth module 2€Led buttons transistor relay screw connector etc. 7€Power supply 10€ (I had a power swpply to reuse but I'd like to put It inside the old case of mini ITX power supply).linear bearing 3€I grab Nema 17, damper and rod and other from old printers.PLA for structure and PETG for gears about 10€.Case is an hold mini ITX case with fired power supply.Dremel like with case and a lot of unusef thing about 24€.Shuco plug 4€.At the and about 45€ for the machine and 24€ for spindle.The price depend on what you have unused in your home, my first CNC made with an old epson scanner plexyglass and other few poor material cost about 20€.

Hi Carter,What do you mean? The total cost of the various components? Or the time it takes?

Thanks, I think professional It's too :D

HiYou can find gcode for standard library here:https://github.com/xreef/LiquidCrystal_I2C/tree/ma...and gcode for custom library here:https://github.com/xreef/LiquidCrystal_I2C/tree/ma...all created using the guide I write here:https://www.instructables.com/Milling-PCB-easy-and-Cheap/Bye

Hi,Try this sketch first, https://playground.arduino.cc/Main/I2cScanner and check address, if it not find the device invert a4 and a5 wire.Please resend link I can't see it.Bye

Hi, Send me the sketch file, seems an error on code.Thanks

Thanks, you are not the only people that notice the reuse of computer trash, other ask me to add on my youtube a playlist to explain recycle (my cnc final cost is about 40/50€ of parts).A lot of my project (Router table also I reuse some part of an old cabinet and low cost wood) are ideas to reuse some "trash".For the noise I advise against the use of the dremel, I control my cnc to arduino via bluetooth because I can not stay in the same room: P, but dremel (clone) can raise 28000rpm with high power, low voltage motor have less power.But next thing to do is an article about "trash".

Hi, I went to see Abrams' project, It's very beautiful, the plywood is more expensive than the OSB, but easier to work with.Yes, a router table It's too usefully in a workshop, I need It.

Thanks, when I have time I try to do some video (whit my bad english) to explain better the process.

It's a beautiful work.I didn't know this framework, I am a front-end developer, and in the future I'd like to create cloud services to interface with microcontrollers as progressive web app, but as you have show to me there is already a base to work on. I'll implement some web management interface as exercise, maybe I'll write an instructable ;).

The process is not difficult but some trick help. If you have had feedback from your students, tell me if there are parts that should be explored or explained better, perhaps adding some videos.

Thanks, I hope this inscructable help you to overcome the problems I encountered.

I'm going to read It immediately. ;)

I don't know if exist on your country, but I find quite good price from LeroyMerlin (near my home) https://www.leroymerlin.it/prodotti/tubi-e-raccord...3/4" of diameter is sufficient (and cheap) but 1" is more beautiful on 1,70m*0,72m desk. And 1m of 1" pipe about 7€.You need this elements for 1,70m*0,72m desk:9 * 50cm 1" = 3,27 * 9 = 29,436 * 10cm 1" = 0,78 * 6 = 4,682 * coupling 1" = 1,07 * 2 = 2,143 * T (TEE) 1" = 1,77 * 3 = 5,311 * Cross 1" = 3,65 * 1 = 3,65The total cost is 45,21€.And you need to cut for the back legs.Bye

hehehehehe.. thanks

hehehehe.. Thank you, I hope my wife think the same.
