Feature Requests / Disable Emergency Mode

« on: March 27, 2011, 11:59:16 PM »

I think an emergency mode should be an elective setting in the software, so if Mach3 becomes intelligent to know if a CNC is operating out of control, it can automatically End the Program when things go out of sync.

What is emergency mode anyway?

Show"N"Tell ( Your Machines) / CNC Record Cutting Lathe

« on: March 27, 2011, 03:02:18 AM »

Alrighty, I started making my own machine about a month ago and wanted to make a record cutter so I could cut my own tunes here at home. The only problem was that some manufacturers charge about 10 grand for a decent cutter. Forget that, I'll build my very first machine ever myself, program it and get it running the way I'd like.

Though a work in progress, it all starts with an idea that you build on top of, and I did just that. I'm building my CNC record cutting lathe right on top of a Gemini SA 600 DJ turntable!

To my knowledge, there aren't any CNC record cutting machines out there, and people keep telling me if I want a record cutter, I'd be better off to build one. With my setup going, The next thing I'll be doing is mounting the frame for railing, adding the cutter head, and making final adjustments.

This cutter is going to be the best, I gave it spliced wire audio inputs, 8 gauge wiring for the AC audio, four 100 amp fuses on each line, and will add in a couple ammeters to read amp reading during cutting. I'm working on the cutter ytoo, which has two electromagnets powered by Neodymium, the strongest magnetics on Earth. The voice coils I built are very small about an inch, and very loud from the magnets that amplify the electro-magnetic core about 1000x. I gave the unit handles on each side too so I could carry the CNC around! 

I should have full frequency when finished, and figure I can get it to work with around 100 watts or less. I just put the huge fuses on to make the unit look cool when its built. Don't mind the messy wires, they'll be bolted down very soon. Not to mention I took the tonarm aoff, when the CNC is done, The cutter will take up its space.

 Update to follow.

Feature Requests / Find a sure way to assign XYZ,ABC to LPT1 pins correctly.

« on: March 27, 2011, 02:02:21 AM »

I've tried various combinations, and can't assign Z to pins 16 17 successfully, which is my controller's A axis.

The board I have is XYA so I'd like to find a way to assign G-code Z to that A port on pins 16/17 on the board.

Feature Requests / Config/Motor Turning

This portion seems incomplete.

Can you throw in Steps Per Revolution, lead screw TPI, Inches per minute,  Additional acceleration rate.

I can't find accuracy with the way its set up right now. You just have it listed as Steps Per. Steps per what? meter, yard or mile?

Mach Screens / Mach3 CNC Lathe

Alrighty, my motor controller isn't working with cnc mill, turning or plasma but works fine with Qbasic from the 1980's.
