FAQs / Re: I have an IPM problem

I'm not sure I'd call it a problem. It's just that your PC runs Mach3 a bit slower than normal, resulting in a slower than expected feedrate. What type of processor are you running?

The spindle delay is set in the spindle tab of Ports and Pins.

What is your actual frequency? Instead of 25Khz, it's probably a bit lower? I think the actual feedrate is tied to the frequency, so if your PC runs at a slightly slower frequency, you'll get slightly lower feedrates.

Did you check to see if maybe the feedrate is correct, and just the display is wrong? I've read that the displayed ipm can vary a little based on the actual kernel speed I think. I know mine displays a slightly different number than the commanded feedrate, but i'm going much faster, so it's not a big deal to me.

Flash Screens / Re: Lathe Flash OEM screen for Mach3 (testing and comments wanted).

I was trying to learn Flash to make screens and had the same problem.... no Toolpath. I installed 3.42.020, and it worked. Then, re-installed 3.42.033 and it's worked ever since.

Is that M13 supposed to be M3?

Sorry Rich, but that's not correct.

I is the X coordinate of the arc center, and J is the Y coordinate of the arc center. In absolute IJ mode, they specify the actual arc center. In Incremental IJ mode, they are relative to the start of the arc.

Yes, the lip would be better cut first. He'll also need some way to keep the part from coming loose and being damaged. This way would be better.

General Mach Discussion / Re: Why Mach3 "Pause" for split second on every G-code line ?

« on: October 16, 2010, 07:26:11 AM »

Are you changing this? You want to select Constant Velocity, but turn off the other options. Here's how mine is set.

If you get excessive corner rounding, you can try setting the angle setting to 89 or 90 and enabling it. Also turn off the 2 CV options on the settings page, CV distance and CV feedrate.
