Nice video, Can you also tell if it's OK to upload code /sketch from Laptop to Arduino with the CNC shield on piggyback while Arduino is connected over USB and also when the 12v external power supply is connected to the CNC shield. OR should we turn off the 12v external power supply to the CNC shield and then upload the sketch.
@hillstudios4 ай бұрын
Depends on the code you are uploading, if you are just uploading the grbl sketch nothing will happen even if the 12v power is on, you have to send g-code files for the steppers to start moving.

@@TheDIMONART Oh, looks like you are right. I thought NEMA was a general rating for torque and speed of the motors, which would limit the range of current and voltage I would think. But it looks like it is rather a measure of the housing face, which might correspond to some of the output characteristics but not the current and voltage input. Thanks for the info, I learned something.

The warning from the driver manufaturer he showed isnt what he is talking about. The manufacturer said not to connect or disconnect a motor while the driver is powered. He is talking about just plugging the driver in without a motor. So it wasnt the plugging in the driver without a motor that destroyed his driver, it was when he plugged in the motor while the driver was powered.

So many questions about this video First of all when the stepper motor is not connected to the board and the drivers are installed he says there is no resistance between the stepper motor terminals. In reality because the terminals are disconnected there is infinite resistance so whats the point being made here. Secondly when tuning the drivers, what is being set is the Vref. You can see that the multimeter is set to read voltage but what he says in "You can see the current increasing". No what you see is the reference voltage increasing and the current being allowed into the stepper motor is increasing proportionally. There is a dedicated formula to calculate the Vref depending on the driver's limit resistors and the motor's allowable current which needs to be calculated and the value set accordingly either equal to that or below that, not simply half of what the rated current is as he says in the the video. @jtechcustoms dude kindly rectify the video
@JannieH Жыл бұрын
Respectfully I don't think you understand what is going on here. What he is saying is that it is unsafe to power up the driver board WITHOUT having a motor connected. This is because without the motor there is no coil resistance. The driver board sees this as an OPEN circuit which can blow or damage the board. Nothin to do with infinity. We all know what he means when he talks about vref increasing the current. You cannot possible have a voltage reading when there is no current flowing. Think about it. There is no fixed amperage for any motor. So you start with the minimum , then test and observe. I run the same stepper motors at different current settings, depending what its job is. I like high current on my 3D printer Extruder. Much less current on the Z AXIS.

I tried it my own... You can for sure adjust your current even if you don't have the stepper motor hooked up. You just connect your Arduino to usb (not ide interference needed. Just connect the usb to the board and your pc) then supply power. No need to match the maximum current of your motors... You can use any supply that matches your voltages needs. In my case my stepper motors using 12v and 6 amps supply... The drv8825 is set to limit the current at 1,2 amps. My motors can handle up to 1,3 amps. No smoke appeared. Im going to upload a video of my set up and my cnc after i finish my laser engraver project.

I would love to see u do a video on them but I also want to take a minute to sayt a huge thankyou bro. Ur video actually went through this shit step by step and u made it look a helluva lot simpler than most of the guys and g'yall's on here,, They normally rush like a headless chicken threough the electronics part of their videos and I hate that so a massive thankyou to u Sir for taking it slowly for Electronics dummies like my good self.. Good self? Yeah I'm not really too sure about calling my self my Good self but what the heck..LOL. Do u have any tutorials on ur channel where u do a smiilar thing with the TB6600's instaed of those little stepper drivers? I would very much appreciate ur advice bro. Also anybody in the comments? If u have any information u can add to help me I would be very grateful. See I'm about to embark omn the maddest thing I've ever done build wise. I'm a complete newbie when it comes to CNC's and electronics but I'm going to attempt building my own CNC Router while I'm off work for the XMAS HOLS.. I know it's crazy for somebody with no actual experience with G-Code, or Cad/Cam, etc .. I'm going to attempt this thing guys so wish me luck and ifg u have any great video titles to drop into me on here I would love that. Now I'm looking for slower style videos on how to wire up the whole thing. I have all the gear to carry out the build and I'm going to attemot using Arduino and GRBL too. I have the motors 2 Nmea 17's, 3 Nema 23's (shoulda been 4 in the kit nbut one was broken) but luckily I have enough motors and I will use the 2 Nema 17's on the X AXIS and 2 Nema 23's on the Y1/Y2 AXIS as well. I have a Nema 42 it looks like on the Z AXIS but it's smaller than the Nema 17's which I find strange tbh but how or never we go at it next week guys.. I have all the Aluminium I need for now. 2020 (10x1200mm lengths) 2060 (2x1000mm lengths) and 1x600mm which I will maybe use for the X AXIS for now but I'm still in 2 minds as to what the final size of this CNC will be. I had originally wanted to go all out for 1200X1200mm but I couldn't get 1200mm 2080's or 2060's so as I had a 600mm 2080 I thought maybe I would narrow the width to 600 and make the length 1000mm? I'm still in 2 minds atm but I need to make my mind up ASAP bro..haha! Thanks again for the great video. It's helping me out a heck of a lot bro so keep up the brilliant work here..
