First part off the BP retro

[DennisCNC]

Here is the first part made on the converted M Head BridgePort that I finished a few days ago. The plate is 3/8 and milled in one pass. I'm runing Mach3 with Centent 10uS drives and ~45V with 720oz motors. The drive is 2:1 with original lead screws with good backlash it dosen't reflect in the things that i'm making now.

One Q?
I did a DXF from Rhino and converted with in Mach. The big arc in the back of the plate is pefect but the sides as you can see are lines. How do I make smooth sides?

[jkeyser14]

I've never used Rhino, but in autocad there's a setting for arc/circular resolution. It might be in rhino's export to dxf feature, or in one of the options tabs somewhere?

That's just my stab in the dark.

After looking around more I saw the "Polyline Max Angle" setting. It was at 10 deg. The lower the number the more lines I get.

Thanks for the tip (jkeyser14)

Yeah, I got a BIG smile now

That's pretty sweet.

Do you have a thread on your build? I'd like to see some pics of your machine and how you chose to mount the motors and such. Details are good.

Looking good!

I recently completed a BP clone CNC, Mach3, Geckos, giant Nema 42 steppers that were on the machine when I bought it with a missing controller.

Here's the first part that really used CNC for something I couldn't have done on a manual machine, a rocket nose cone for my son's science project, using the mill like a lathe.

Its funny, it looks better in real life, for the some reason the picture makes the machining marks look less regular than they really are (yeah right, but at least I believe it).

Yeah, what Scott said. Lets see some pics and some details of what you did and how you did it. Maybe start a new thread just for your machine build and pictures.

The controll box still needs work. I don't have the Z finished yet. I'll take some pics in the morning and start a thread.
