Yeah, nothing seams to improve Mach2/3 for me either. I finally just installed FreeDOS on a 128 Meg Compact Flash card and connected it to my motherboard with a CF to IDE adapter. Now I can just...

Does anyone know of any CNC control software that is accurate with the dwell timing? mid2cnc.py uses for example "G04 P0.1500" for rests and Mach2/3 doesn't seem to take dwell timing very serious and...

I finally figured out how to use the mid2cnc.py script. Come to find out, it doesn't work with Python 3.1 (at least not the windows version). It works great with Python 2.7. I wish I would have...

Great work P.Passuello, thanks for sharing!

Awesome, it's good to hear you got it working BTS. :)

I was working on a C++ program to automatically convert MIDI music to gcode, but it was a huge pain and the project kind of died out. I did...

I have posted instructions on how to make music with the stepper motors on your CNC machine in this thread.

mojojerry,
My CNC system is fairly simple. As I mentioned before, I am using a PMDX-122 breakout board which is connected to the parallel expresscard. I have four Gecko 203V drives connected to the...

mojojerry,
I was just using my machine the other day. I was having some trouble with Mach 3, at first I thought it was a problem with the card, but I had just installed a newer version and hadn't...

Roadstercycle,
I don't have limit or home switches on my machine, it's small enough that nothing is hurt if it crashes. I have a PMDX-122 breakout board connected to the PCIe expresscard parallel...

thanks pminmo, that was a fast responce.

I just got the parallel expresscard today and tried it out. My laptop is a Gateway ML3109. I have it set as a desktop in the power settings. I ran the Mach 3 driver test file and the wave form is...

That's a good point Mike. I hadn't thought of the CPU clock speed throttling. You can usually set a laptop into performance mode in the power settings, which is supposed to keep the CPU running...

I've read about the dirty pulse stream in quite a few places including I believe in the Mach 2/3 manuals. I've also read about a lot of people having success. I'm curious if it may be possible to...

I agree, bag pipes are probably the best match.

My kids love it when I play music for them on the CNC machine, especially star wars. I wanted to share what I've done so everyone can share those...

I've been doing some research today on possible solutions for the parallel port dilemma of late.

Torchhead makes a good point, desktop computers really are the way to go if you have the space....

Brenck,

The Star Wars g-code is in inches and designed for a machine set up for 40,000 steps per inch. That's 1,574.8 steps per mm. You should be able to change your motor tuning to match that,...

Here is a Blink 182 song I partially converted to g-code. I'm including the MIDI file I used to get the sheet music, along with the excel spread sheet I used for converting, and the g-code text file....

I found that Dwell doesn't work very good for rests. I'm going to experiment with frequencies below the human range of hearing to give the machine movement instructions that can't be heard, so they...

I figured out the math required to play cords. I'm attaching a word document that contains all the information on how to do it.

With this information you should be able to figure out numbers for...
