Been folowing all your work.
Great stuff.
Keep the vids comming.
Are you planing on using the plastic printer to make molds or is it more proof of concept?

Im not really up on the VFDs but I dont think you can use them for 3 phase transformers as your mill has in it.

You would have to remove the old control and make a new one and us the VFD for the...

Well I have some success. The problem I am haveing is I have a small radius lead in/out .200". Mach doesnt like the cutter bigger than that small radius? It wont run the code if I put a 1" too in. I...

If its a rotary phase start it first check your voltages. Your made leg sould be a little high cuz once you load it it eill come down. I ran my boss 5 off of a 5hp RPC and it did fine. It was a home...

Ok thanks guys I will see what I can come up with.

Thanks for the replys fellas.
Are you talking cutter compensation in MC? I think maybe changing it from computer to control?
Or is it somethoing the the post that needs to be changed?

Ya you...

Yep conventional milling is the way to go.

Thanks
Stephen

I use Mach 3 you can down load it and trial it for free maybe you can with emc2?

I find for me the simpler the better. and Mach is pretty simple. The problem with trying this and that it takes a...

Its been a long time since i dusted of the manual.
I guess i will have to RRTFM
Thanks for the great help LOL

Hey all is there an eazy way to add or subtract a few thou from a tool path in mach?

Im cutting a 2.670 hole using a 1" endmill. The program is generated by Mastercam. Just looking to tweek the...

Im using Larken cobra drives 9amp Im rumming 70v DC to them.
Yep the motors are old could be a little demagnitized.
I will have to find a way of calculating side load and figure what the motors...

I just had a look in my origonal programing book and it says 1.5cubic inches/min. in mild steel. I guess I will have to do some math.

Question for you fellas with the old Bridgeport CNCs.

Bridgeport boss5 converted with origonal steppers on 70v DC wired in series.

1020 steel

1" rough end mill 1.5 doc
250 rpm 2ipm feed...

Must have been my code it seems to work fine now.

Hey all. I haven't used my mill for a wile. I was writing a new simple program to cut some barrel flutes. Wile doing some testing I tried to speed up the feed rate with feed rate arrows and it...

Hey sorry I haven't been on the board much lately.
I don't have a VFD I use a RPC.
My E-stop could happen at any time once the axis started moving.
In my setup I have the BOB and 3 Cobra drives...

Got er figured.

I sounds like your program is trying to move the Z faster than it is able too. I would adjust the program.

I have tried grounding just about everything. I have some wiring that isnt shielded. I just picked up some more shielded wire and will repalace anything that isnt shielded. I think the stepper wires...

Hey fellas.
Problem I am having is I keep getting an errant Remote e-stop. It can happen any time cutting or not. Sometimes even if I move the mouse it will estop, without steppers running.

I am...

What I am trying to do is cut 6 flutes down the side of a .7" round 4.4" long.
I would like to use a bull end mill off center so I can get a different profile rather than a ball on center.

My...

There is a mach 3 post on the net some where.I think thats what I use when using the A axis. Its that or the mfpan or somethnig. I think there are are about 4 changes in Mach that you can do and I...

What software are you using to control your mill?

Is it possible to use axis substitution and run the Z axis say 1/2" off center of the rotary axis?
How would one go about it?

Thanks for any help.

STephen

Thanks SM.

Hey thanks for the help I really appreciate it.


Yep.



So I would have to alter the "drawing" line ends then apply the tool paths to that?
Does it make any difference if I draw the lines...

I was looking for the thinning affect as the flute ends mostly. Yes even after doing a couple of dry runs with a small marker in the quill its still quite nerve racking when you hit the go button. ...

I have had some luck but if I program a lead in with the same program I still get different feedrate for every move.

Any ideas fellas.

Hers the first trials....

Hey thanks alot Jeff. I will give that try.

Stephen

Lets see if this works.
Hey there it is.
Let me know if it works.
