localbroadcast: is there any way you can use a different type of sensor on your axis than the encoder on the motor in order to give feedback to the software that the motor has gotten the machine where it was supposed to go? I'm just thinking this because then I could use a different drive mechanism than your standard servo / stepper with encoder..
marshalcraft: hey neo7cnc ive just broke ground on my cnc project by purchasing a rotating tilting table that i intend to convert to cnc for a 4th and 5th axis. any suggestions for servos as i do not know to many brands. i only have 120 v so would probably have to do some kind of voltage converter or something however the table is geared for 1 rotation to every 90 rotations of the worm shaft so i dont think much power is needed. do they make 120 v servos or am i going to have to look into a converter of some sort, or moving.
Steven Reynolds: Hi, thanks for some great advise,
just been looking at some steper motors for my CNC build (23KMK04499V P14288) wonderd if you think they would be ok (thier 24 v as difficult to find 48v here in uk, and what would you surgest for main motor as I have no idea
Иван Козловский: Я ОДИН
Ron Edmeades: Great video. I would be interested in a video describing how to choose the size of your stepper/servo motors. Being a novice when it comes to cnc machine design it's one of the difficult topics.
jimlovesgina: This is a great "Here is what you can do" series of videos. I would love to see a "Here is what I did" series of videos with a set of plans. Something that already works well would be great for avoiding the costly mistakes of designing one from scratch. The result would be a router that works. Your plans could always be modified to include a different option that you are discussing but knowing that a working router is the end result is huge peace of mind for anyone deciding to commit to building it.
Galfonz: Steppers loose torque rapidly when turning faster. That's why you can't get high speed moves when using them.
kmcwhq: How wide is that plywood bench?
Tazrahzeljr: dude...that was actually extremely informative! niccee ive been interested in cnc for a long time now and i think its time i actually attempt a design! thanks!!
Neo7CNC: Awesome info. As I tip toe towards a new machine I'll have to dig into all the current tech. Thanks for watching.
Stoney CNC: Great video - and love your videos. Your CNC platform is very very impressive.
Gecko seem to have midbandresonance damping in their driver DSP to compensate for stepper resonance. Great stepper motor info on the Gecko site. I assume the Keling and Leadshine etc's do something similar.
The servo-stepper is a good new technology.
DG4S-016035 - DC Servo Drive allows step and pulse signals to control servo
Au.RaBBiTT .UrbanTerrorPro: Hi mate, I really like your video's and you have done a great job with what you have had to work with, ignore the hater's. Can you tell me as a person who has no idea about the driver boards and so on, can you recommend a good driver board for a 3 axsis cnc. do I need 3 driver boards and what else for that side of things, im using it for wood and light aluminium.
adisharr: Just an FYI, the servo you're using for comparison is very high performance and really not in the same performance category as a standard stepper. That servo motor / drive probably costs around $ 1-1.2K
Also, servos aren't always the best option for machining applications in smaller mills as they are error followers. A stepper is not and will be very accurate unless pushed out of it's capabilities. Note that I'm talking about a lower cost hobby grade servo motor / drive.
Luis de Rivas: The G540 is an integrated 4 axis controller, which means it has 4 drivers. A better comparison is the G201 which is for a single axis, like the KL-5056. Beware, not all drivers are alike. Some feature galvanic/optical signal isolation, some have varied digital micro-stepping capability and the maximum current limit will also be a great factor in the cost of a driver.
For example the KL-6050 is $50 with no micro-stepping & handles up to 5 amp motors. The KL-9082 is $109 @ 8.2A max & w/micro-step
Neo7CNC: I haven't used the Gecko drives but from what I've seen they are some of the best. I have seen them used in midline production CNC machines. Small business and prosumer types. My drivers are Keling KL-5056. Thanks for watching.
Dogfrost9: Hello, When you were talking about typical pricing for stepper drivers vs. Servo drivers, you said around 2 or 300 range for servo and 60 for stepper. In my research for a good Stepper motor/driver system I have been seeing a lot about Gecko G540 Driver for use with Nema 23 Stepper motors, however JUST the Gecko G540 stepper driver on ebay sells in the $250 range. Do you know anything about the G540 and why it is so much more expensive than the $60 driver you used? What driver was that btw
José Yovany Luis García: If the amperage is a problem, you could build yourself (if don't want to spend) a controller based on a Mosfet H Bridge, you can use an IRF Mosfet and it would be able to handle much more amps...
Karadjordje Trkulja: Great and helpfull video. Thank you sir. And now I can seartch for stepper motor. I want to build my first 3-axis CNC Milling machine 70x100cm working area. For my first CNC I think that steppers are good choice.
Neo7CNC: I want to think as long as you don't push to hard or overload it you'd be fine but I always try to error on the side of caution. So if your worried about smoking it I wouldn't try it.
Dan Regalia: I'm using the Ardurino Uno board Revision 3 using L298N Stepper Motor Driver Controller Board for Arduino.

jrjubach: You can call the sequel "21 and HUNGover" Alex Krajci: One Of My Brother Jesse Krajci's Friends Yan Saw Watchmen With His Dad When It Came Out In 2009. darkchaoszeroomega: What are the differences between Hunting Ground and The Hidden War ? natigoma: Puta madre, ya no hacen anime asi! con historias que llegan, llore como una loca. tremenda serie! la miraba alla por el `94 Ryan6700: Why did their company have to shut down :( this game was amazing. I wish someone else could have picked it up. LadyEMC2TV: I want to try this bronzer. It's on my wish list. Thanks for the review. :) Mike Hunter: If the muzzle is net exactly straight and flat across it will cause instability. Gas is trying to pass the bullet all the way down the barrel but is retained by the bullet. When the bullet exits the barrel the gas passes the bullet in a even circular wave. If the bullet exits a muzzle with one side of the bullet exiting a 100 thousands of an inch for example ahead of the other side the gasses will squeeze around on that side first creating a wobble. The spin may stabilize it but accuracy will suffer. I would have it re crowned at the very least. It's not that costly. Note: It is his gun and he can do what he wants within the law sooooo....cool video.
