That “Ahh Haa moment” I figured out that I was expecting the A axis DRO to move in unison with the Y axis DRO when I slaved them together. When I said the motor went dead I should have said the DRO...

My A axis stops working when I config to slave it to the Y axis.
It works fine and jogs when its independent , I slave the axis to Y and reboot and its dead, remove the slave config reboot and its...

What determines weather you decide to connect your motors PNP or NPN.
The manual gives me options to wire the step and direction ether + or = ground.
What is the deciding factor. Does the decision...

Thanks for your reply John-100
The default dip switch already has the charge pump turned off. and the manual says the charge pump will not affect the operation of the e-stop. Good idea though
My...

I have a new PMDX 126 B.O.B it still has the jumper from e-stop to ground. when I power up the red LED should lite for 1 second then go out. the problem is it stays lit all the time with the...

Are there any settings I need to adjust to make the 64bit version work or play well with others?

Will a 64 bit version of windows 7 work in mach3 if I'm using an Ethernet smoothstepper ?

Will Mach 3 throw an error code if the Z axis can't accelerate fast enough to keep up with X and Y or do you just lose steps and have an odd looking part?
So the whole point of my first...

When designing a machine, should it be a desired goal to gear the Z axis the same as X and Y?
Should it take the same number of motor steps to move Z one inch as it does the X and Y axis to move one...

Is there a right or wrong way to designate your axis? With Z I think there is no question. With X and Y is there a rule as to what determines which is which or is it up to the machine designer as to...

Do HP notebook's have a compatibility problem with CNC controllers or mach-3
Is this computer a good choice for my CNC project. I read somewhere that this computer
has issues getting along with...

I'm not sure what you are using this for. But I think you can achieve your goal without a special drive motor. you can do this the easy cheap way with a bypass valve you can use a needle valve if you...

Hi
I'm not sure where your going with the 1/4 maisonette idea.
with a four axis foam cutter normally the foam stays still and the wire moves.
the four axis are called X.Y. and U.V . so you will...

Can I gang two 3-axis controlers together under mach 3, and have a 5 axis controler?

using mach 3 can I have multiple axis configuration with the same motors?
example
config#1

I bought Bobwire to try with my hotwire. I haven't built my machine yet, so I may have put the cart before the horse. Bobwire is made for EDM machining that uses 4 axis just like hotwire. If any one...

Just a word of caution
cutting wood and metal in the same shop is a fire wating to happen.
I run a cabinet shop and sawdust hides everywhere, a spark can smolder for hours and then flame up long...

Hi Butch

Have you bought your bobcad software yet? If you want to cut wings with a taper profile you need a 4 axis software like bobcad wire EDM version, or some of the other software found in...

I don't tkink the salesman knew what I was talking about eather.
If you want to cut 2D Bobcad 19 or 20 will work fine. If you want to cut 3D like a tapered wing or a cone shape you need 4...

In some of the literature I got from Hotwire direct, the bigger CNC foam cutter mentioned they used timing belts.

Try this web sight
They have software for cutting wings. Starts at about $38

I'm with Jimini
Keep it simple, the fewer pumps, long hoses,stepper motors the better.
I say use a fixed gantry with Y axis moving your three hot pots right above your moving X table with solenoid...

Looking for help.
I am wondering if anyone has information or a manual for the Seiberco AIM5000 controller. Is this controller for stepper or servos, and what size motors can it handle? I found one...

Can BobCad 19 machine round columns like Artcam, using a "ring" function to unwrap or wrap parts from flat to round. And use the X or Y axis to drive a rotary device?

Marc

I just bought Bobcad wire EDM 4 axis software. I hope I didn't jump the gun.
Bobcad sales assured me it would work for a hotwire foam cutter with 4 independent axis XY and UV. I'm not so sure the...

Hi Patrick
I looked at the Automec web sight. The motor specks say 46.5 in/oz @ 3 amps
can you really pump 20 amps through that motor and get 360 in/oz of torque from that motor? And 3 motors at 20...

Hi DBASSETT74


Why are you trying to make this part. Cant you buy this as a replacement part. are you trying to modify from the original? How many do you need to make? Usually this kind of effort...

You don't reuse the wax it stays in the mold and is vaporized when you pore in the hot metal

I think it would work best to make a sand plug for the bore. Then you break out the sand later. It works like this. make a wood plug the shape of the inside bore plus say 1/2 inch longer top and...
