General Mach Discussion / 7x10,-12,-14 Mini Lathe Spindle Speed & Direction Control

« on: September 24, 2008, 08:31:28 AM »

I have just posted my wiring diagram on a new web page (link below). The diagram shows the inexpensive model C6 speed control board from CNC4PC.com connected to the FC250J/110V DC motor controller board that comes on many late model 7x10, 7x12 and 7x14 Sieg C2 style mini lathes. The diagram is accompanied by lots of text describing the modifications and operation and set up in Mach3 Turn. I am also offering spindle interrupter discs for sale ($5 + $2 S&H, US only) at my new lathe pages. These discs fit the 27mm spindle and are meant to be used with an opto-interrupter such as the Fairchild H21A1 (available from Digikey) or lots of similar devices. The site is at http://tetralite.com/lathe

LazyCam (Beta) / OK, I give up! How do I get ACAD dxf files to open in LCAM 2.02?

« on: May 21, 2007, 07:36:04 PM »

Hello all. I recently purchased the license for Lazy CAM Pro and have been having very little luck getting my AutoCad generated .dxf files to open in LCAM and it is still a problem with the latest version (2.02). I did manage to do it on an earlier version but I can't remember what I did. I think what I did was go to this forum and find some ideas, took my file into another program and did something to it and it worked. Shouldn't this be easier? Does anyone know what is required of an AutoCAD .dxf file to make it readable in LCAM? I have tried saving the .dxf files in V2004, V2000 and Vr12. A couple of my old files still open (the ones I did the mystery process to) so I know it must be a compatibilty issue with the straight ACAD files. It seems very wrong to have to create a ,dxf file in one program and then take it into another to fix it so it works in LCAM. It's called "Lazy" CAM -- I am doing my best to be lazy! Help!
