hi
can i use irf 730 as there is no other

How to check the electronic system without connection to the engine

Please help me i want to know the specifications of capacitors?

could you use drawer slides as opposed to the bearing setup. I've got the pipe frame built and trying to keep this very low budget.

Hey,
Great job with your CNC machine... I have a few questions though...

Will it cut through ply wood (and what sizes)?
What is largest size it can cut?
About how much did it cost (including motors, and controller)?
Where did you get the components?

Thanks

To Tom McWire:

Can you modify your cnc To become a 3d printer????

Hi Tom!. Congratulations for your machine!. I`d like to ask you if your machine can be used to make PCB boards or it`s only for milling stuff. Thanks Have a great week! Kilo

this is my machine so far (i hope the motors can handle this)
and my etched pcb (still having some trouble : / )

Anybody please help with a little info. The question is...

Am planning to make a 4' x 2' CNC Laser Machine. does this controller and those motors support that?

If not, any suggestions for the modification?

Awaiting replies...//MEROG

any shopping list with links?
maybe an assembly manual of sorts for the card and motors.
then maybe a initial setup tutorial? Like zero'ing the bit, and work area.
any preassembled kits (electrically) for sale?

Hi, I have a question: Do you know the dimensions of the usable area of the McWire Cartesian Bot 1.2 on the RepRap website? Just curious. I'm going to build a Rep(St)Rap.

my idea is in your instructable and would proably be more useful to reply their but here it is so your not confused.

good day. very interested in your project. than replaced in4735.   grateful.

what are you guys using for steppers as far a .oz of torque? i was looking at nema17 in the 45-75oz ratings, is this sufficient for the z axis for what this machine was designed for? for a motor i will be using either one of the dremels, possibly one of the harbor freight "equivalents" or the shaft driven setup. also, can anybody recommend a cheap driver/breakout board setup that definitely works w/ mach 3? i have been out of electronics for quite some time, probably 10yrs or so, so a kit would be nice and i don't have access to the equipment used to make my own boards anymore. i can read schematics and know orientation and kind of remember the resistor color code, but i am rusty and i also don't want to have to buy a large quantity when i need just a few items. should i go for 5V, 12V or 24V motors? this will be used for education as i am learning solidworks but really need to learn the cam aspect and figure this would do the trick as i am not into the virtual cnc machines, i want to see a finished product. what have you guys figured the decent setup size is? i was thinking something maybe a bit smaller in size compared to the McWire Cartesian Bot v1.2 but a bit larger than this one. thanks in advance, bob

Very good work Tom, congrats on the number one finish! You deserved it.

Tom is there a way that there are instruction and a meterial list to this project?

Tom, this is stunningly good, I like the simple low tech engineering to a high tech machine. I am in awe. many thanks kind regards Malcolm

Hi Tom What CAD software would you say is god for for 2D & 3D project Thanks

Hi tom is there a way to put limit switch's on this Step Driver circuits the help will be grate Thanks

What are the MOSFETs and diodes you used for the motors on your CNC machine?

Hi grate site, I was trying to work out if this Driver circuits is for a Bipolar Stepper Motor or a Unipolar Stepper Motor, you may of said and I've mist it Thank for any help -Mark-

Hello ... I'm from Iraq ... that this great work.. I'am very impressed by your work .. it is the competence of high .. It encouraged me to work on the machine .. But I can not find Chip cd4028 or Equivalent to it in Iraqi market of electronic . and There is no import of this chip because of some alleged that he entered in the manufacture of explosives by remote control. I did not find equivalent in my data ship. Is there an alternative or there is another way For canceling it ????. Please .. Including to me and the methods used. And accept my sincere thanks and appreciation .... Sorry,of my English is weak .. Thanks

Will HP printer motors work as stepper motors?

Ok, i finished my pcb and soldered all the parts on it. is this the way to connect the motors? (the circle with the X in it is the light bulb) i only want to be sure that those blue marked soldering points are nothing important i might have forgtotten. now i need to know what kind of bulbs to use an what voltage you recommend. on my motor it says 4.0V/Phase... does that mean i need a voltage of 16v?

Hi, i am currently designing a desktop CNC machine and i am having trouble finding a suitable stepper within my price range, could you tell me where to source the components and the circuit board? Could you build a stepper board that i could buy from you? thanks, Sam

hi there loved the cnc, always wanted one and now I can and I was wondering if the stepper motor controller you made up can it be used as a 6 axis controller as I would like to add to the cnc later on

Hi Tom, I'm building a mill myself, but was unable to find a cd4516 ic at my local electronics store. So i bought the closest part i could find which is a 74ls169. I was able to breadboard a single motor circuit using this ic. I'm wondering if you have any thoughts about using this part as an alternative. Also what program you used to make the schematic and if you could send me a copy so i can edit this ic into the schematic. Thanks.

Hi tom can you directly control motors from circuit w/switches, if so where would I put them? THANKS TOM Great site and info, this is first circuit I've built just need to test and connect, add few bolts. will send pictures of mill when I get motors connected.

Thanks for the vids . I'm building a table top mill and you have definitely inspired me. being a newbie this is my first build. The X and Y tables are done and next is the Z and circuitry. when I get to a point I'll put my vids up to share with other people , and maybe this will help in there builds. Mike

Tom, terrific stuff! I was looking for a really simple CNC to play around with before building a bigger toy. I'm off to the hardware store right now! Regards Geoff
