CNC stepper motor Answered

Hello, I would like to use my 3 printer scanners I recently salvaged for a CNC. Would you expect the motors to be able to cut aluminum with a multi-speed dremel? If there is enough torque, it would be sufficient to make a 3d printer right?

CNC Homing

Hello, I work on CNC Alamode project, raspberry pi and Alamode is configured to control 3 stepper motors: My configuration: Raspberry Pi Alamode (Arduino compatible), 3 stepper motors and 3 EasyDriver. Everything works, grbl is ok. Here is my story: I wanted to install a homing system, I first started with the x axis, as in the drawing, it worked well, it has stopped the motor, but I realized that the current 5v  passed directly on Limit X (D9), without 330 Ohm resistance. Then I put this resistor like a drawing but now the homing no longer works. My question is: Have I damaged my card, knowing that everything works? Can I redo my original configuration without resistance? My last statement :  4.96 Volts between limit x (D9) and Ground. Thank you for your help. http://www.exonet3i.com

CNC help - Software?

I'm planning on building a X-Y CNC machine.  The issue is softwares.  My plan was to get 2 scanners, and rip out the stepper motors.  Then, as seen on an instructables, use a parallel port with 2 or 3 ULN2003 chips to control the motors. My idea was to do as they did, and use TURBO-CNC to controll the parallel ports, unless there's something better to use? Can TURBO-CNC read G-Codes?  If so, what is the best program to use for creating G-Codes? This project is starting with a 1W blue laser as a etcher / paper cutter CNC.  It it going to be used for getting my machine tuned up.  Once things are in good order, It's going to be turned into a 60W acrylic / 1mm aluminum / thin wood cutter.

CNC mill stepper motor controller

Hi y'all from France! I've been aching to get my hands on a CNC machine from quite some time now, unfortunately I'm quite a noob when it comes to electronics and such. I'd found that while the machine itself is not that hard to build (see all the ables), however the electronics involved are just too complicated for me to build a controller from scratch. I've found the other day some seller on french ebay selling a complete controller without the power supply, so I've been wondering about it but am not in the position to fully understand that piece of equipment. So my question is: what do you think about it guys? Does it seems to be ok (BTW I've also found 3 NEMA23 stepper motors, precisely the same model as described in the specifications for the controller board on its seller's page)? For now I just want a three axis CNC machine capable of cutting polymer foam and soft wood, so I don't really need expensive and powerful stepper motors. Thx for any kind of input!

Looking for Info On These CNC Motors For Replacement

I purchased a surplus 2-axis CNC machine with built by Yamaha. I hoped to rebuild it into a new machine for myself, but it ended up requiring 200 volts AC for the controller and motors, which I don't have access to. I sold off the controller already. I don't know too much about professional CNC macahines, hoping someone has some input. I am hoping to replace the motors with ones in the same form-factor that run on DC or 120v AC(if such thing exists), preferably stepper type. I do not know what form-factor/package/mounting style to look for, or even if any are available with the power requirements I want.  Motors are the same for both axis and are part#: TS2620N664E122, attached are some pictures.

Which Stepper motor and which controller?

Hello, Still in research mode for my own CNC machine which will be Arduino based. But, as everyone is using different motors and controllers (drivers?), how do I choose the right one for me? My machine should be able to do soft materials like wood and plexi/acrylic but I als want to be able do mill/cut aluminum, as I am restoring an old car and parts are not easy to get hold off. For my board I was thinking of an Arduino UNO (like most) but then, which motor to go for? Uni or bipolar? 17, 23, 34? And which driver? gShield / CNC Shield V3 / Dual step driver? A4988? 1 board per motor or can I combine them? How to get a smoother run then 1/8 steps? (Found CNC Shield V3.0 + UNO R3 + 4pcs A4988 Driver for £15???) I have never soldered anything, but I am a fast learner. So far when it comes to electronics, I managed to hardwire a stereo without harness into my car, speakers, radiator fan circuit and some door controlled LED's. Far away from soldering of building a CNC, but I am up for the challenge. I know there are a lot of questions in this post, but I appreciate any explanation why someone chose one motor over the other etc.... Any information is highly appreciated. I rather research more then building something and then have to start over again. Kind regards, Red

CDROM stepper motor problem with movement

I have been having intermittent problems with my cdrom stepper motor. I had a four pin motor soldered to a bare copper wire. I used the pins not the little ribbon cable and I left the ribbon cable attached because I figured, as soon as I snip it off I would regret it later. The other end connects to a breadboard that is in line with the stepper input to the EasyDriver motor controller. I have been using GRBL controller on my PC and when I tested it the first time in a vertical position it would just wobble around, not moving up nor down. I thought the stepper motor was bad so I got another one. The second was wired the same way, 4-pins, and it worked in the vertical no problem. Then later, while working on the rest of my project the second cdrom motor that was working did that same wiggle without moving up or down. I realized that the solder connections were very close together and that two pins were electrically connected. I modified the wire to basically a homemade male to male jumper wire. The extra pin made the room I needed to unsolder the two pins. Once again the motor worked up and down with no wobble. I have done nothing to modify the cdrom stepper any further and went to test my motor today after a couple weeks hiatus and once again, wobble with no up nor down motion. At this point I am stumped. I have reason to believe that my solder skills are lacking and that my homemade jumper has broken internally inside my shrink tubing where I cannot immediately see it but If anyone else has had this problem and knows how to rectify it please let me know. I hope there is enough info here laying out my problem and that someone can lead me in the right direction. If it also helps, I have checked my pin out and I do not feel it is backwards or crossed. I checked the resistance between the four pins and the end of my "jumper" and is approximately, 40, 20, 40, 100 ohms for A-, A+, B-, B+, respectively. I am really not sure what these number would mean but my buddy told me to check the continuity from end to end.

I know motors are mainly metal, but as long as the heat does not build up, the casing should be able to be plastic or whatever material, right? Some copper wire and a magnet should be the only resources else than the building material and the motor could be of a unique design since it would be made by a CNC for a CNC.

UPDATE: CDROM stepper motor moves up and down now! wiggle problem resolved

To anyone who read my previous post about the CDROM stepper motor wiggling and not moving while being controlled by GRBL and the EasyDriver motor controller, I got that same motor to work. What I did was I completely took off the wiring system of jumpers I had made. I took off the male pins and kept only that. Then, I tinned four new 22 AWG stranded wire (which is a larger gauge than I was using previously), attached the male pins to one end, and soldered the other ends to the motor directly using copious amounts of flux and verifying resistance continuity between all wires and connections. My Take Away: A. The previous gauge wire was too small, B. My splicing of the wire failed miserably, C. The solder pins were in fact touching each other, shorting the system I am guessing that a combo of all three (honestly, mainly B) caused the frustration. Now it is one solid wire from motor to breadboard for each of the four connections. I believe by unsoldering everything and cleaning it up fixed the wiggle jiggle of the CDrom motor. So if you are having these problems with your CDrom motor/ motor controller, check the wiring and the solder joints. I hope this helps anyone having these problems.
