View Full Version : Mach 3 Mill feed rates

I'm trying to run Mach 3 Mill in a simulation, and the execution times for simple programs are just plain silly- an hour and 30-plus minutes for cutting a 3-inch by 1.5 inch hole in half-inch plywood?

I've got do be doing something wrong. But I dunno what.

I've tuned the motors to match the 116-ounce motors on the machine, I've tred adjusting the feed rates, and they just keep reverting back to 1. Must be the drawing I imported, but it's a simple rectangle, how tough could it be?

I've downloaded the latest pdf helpfle for Mach 3 I could find. Haven't looked at it yet but I'm headed there now. I just thought I'd ask here to see if anyone had any ideas.

Is there an F1 in the g-code?

ger21

Could you post the g-code for that? Even with the feedrate at 1ipm, it should only take about 10 minutes.

If you're importing a .dxf, set the speed in the import dialog box, use the layer button.

Yes, there are two concurrent F1's in the first section of code alone, and several more down the line.

Here's the first basic section:

G1 X-96.0000 Y48.1667

G1 X-95.6667 Y48.8333

You can see I'm a total newb and am relying enirely on the conferters at this point because I won'tknow what I'm looking at until I learn a bit about the G-Code itself.

I don't even think I know enough to ask intelligent questions. Here's a question: If I change that F1 to something like F40, will that change the feedrate to 40?

If I change that F1 to something like F40, will that change the feedrate to 40?

Sure will! :)

Did that, I lost the motor tuning though so it's still taking

its own sweet time- over 30 minutes to cut about 9 inches!

Appreciate the help, by the way. The toolpath that this converter is using isn't all that efficient, I can see some changes to make already;)

Ok, I am confused. No matter what I do, even if I set the motor tuning to outrageous settings, my speed is ridiculously slow- something under an inch a minute, even with my feedrate set to 100. Any more sugestions?

What might be happening is that the scale of the drawing might be way off, or the scale of the drawing and the scale of the Mach3 software are not the same. I need to find out where the machine limits are so I can see if the drawing needs to be scaled.

Ed when you are in config and tuning your motors, have you been saving the axis after making all the adjustments?

Mike

Yes, I have, but I',m not certain my settings are correct to begin with. All my axes are set identically, and here's a screenshot of the settings:

http://web2.airmail.net/rafalko/mtrtun.jpg

These look like they are in the ballpark for the 116 ounce motors on my machine, so I'm looking at the drawing scale, because my feedrate is at 100, and it's taking way too long to even plunge .

I'm still learning Mach as well, but I think you missed what Gerry said:

"If you're importing a .dxf, set the speed in the import dialog box, use the layer button.

There you can set the feed rates for plunge and direction, I think they default to 1 untill you change them, then they stay at what you set for the futer.

The motor tunning should not matter to generate the G-code, it will generate what ever you tell it to, if your machine can't run that fast, well.....

By the way, is Mach set to run in metric? If so then you are moving at only 1mm per min!

per.e

01-31-2006, 03:42 AM

Try to set the "step pulse" from 1us to 5us.

Hope that helps.

Per.

I did reset the speed in the layers to 100, along with the spindle speed and the tool number. I defined Tool 1 as havinga .25 diameter and 1 inch cutting length.

I didn't change Mach from mm to Inch. I'l'l go do that, if it's not too difficult. Any tips?

ger21

If it's setup in mm, and you switch it to inches, you have to re-tune the motors.

What does the Feedrate DRO say while it's cutting?

The motors are definitely set up in inches, as are the screws.

The DRO is reporting variable values, from around 45.5 to over 145. With a unit per rev of .02.

ger21

01-31-2006, 07:43 AM

If the feedrate DRO says 45, then it's cutting at 45ipm. Are your steps/unit setup correctly? What is the pitch of your screws? Microstepping?

Remember, this is all simulated, I don't have a machine connected yet.

That 45 is the LOW end of the speed, but it's still taking 15 minutes to cut 9 inches.

I don't know if I'm microstepping or not, and I don't know where to set the pitch of the screws.

ger21

01-31-2006, 08:05 AM

Does the simulation take 15 minutes? Or does Mach3 say it will take 15 minutes?

The pitch and any microstepping is figured into the steps per inch, where you have 3600.

Should be 200 x turns per inch x microstepping amount (8 for 1/8 step, for example)

The program SAYS it'll take 15 minutes, it takes about half that to complete on the sim.

I used the 3600 figure because I found a discussion of this setup stuff in another thread somewhere some time ago and the people discussing it found it to be accurate. I went on faith!

Your math says it should be 32000, not 3600, for a 20-thread-per-inch screw pitch. I'll try that.

Doesn't seem to help much. More than a minute just to plunge the bit. And hat tells me it's more than likely not thedrawing scale.

What it says is not necessarily correct. What drives are you using? You need to know if you're microstepping or not to get right number in there.

ger21

01-31-2006, 08:14 AM

Is the Z-axis set up exactly the same as the X?

Yes, exactly, except for the program range limits.

How can I tell if I'm microstepping? I'm guessing yes due to the radiussed curves.

ger21

01-31-2006, 08:19 AM

Post the exact g-code your using, if you can.

Is there any chance you have the FRO (feedrate override) button checked? Its on the right side of the default screen and is expressed as a percentage.

How can I tell if I'm microstepping? I'm guessing yes due to the radiussed curves.

It depends on the drives your using. If Geckos, it would be 10. A Xylotex is 8 by default, changed with a jumper I believe. Not sure about a HobbyCNC, but possibly a jumper as well.

What do you mean by radiused curves? Are corners being rounded in the display?

Doesn't look like it, but it's set to 100 percent anyway.

I'm getting the Xylotex controller, so 8 is appropriate.

Radiussed curves- I'm cutting a rectangular-shaped hole with rounded corners. Instead of sharp, square inside corners, I have a 1/4 inch radius on them.

And yes, they'r ebeing rounded on teh display.

Something also confuses me- I'm not seeing a .25 inch wide bit path, I'm just seeing an outside edge to the cut. If I were to do this manually, I woldn't even have to think about the radiussed corners, it would be four straight lones. That's essentially what I'm trying to do! Four straight lines.

ger21

01-31-2006, 08:39 AM

The display only shows the center of the tool. Are you saying the display shows the corners being rounded, but they're not supposed to be?

Post the exact code youre using.

No, Im saying that the display is showing the corners to be rounded and that the tool actually follows the rounding, when it doesn't have to.

There are TONS of extraneous moves in this code, to my mind. But I have no idea how to G-code manually yet, so I'm going to have to hack the commandset later. It includes several bit lifts ad plunges that really aren't all that neccesary and could be eliminated or altered slightly for more efficient running. Maybe you could try it and see if it does the same for you? I don't think the G-code is the issue, but here it is in its entirety:

here is what the g-code looks like. The problem might be that it's 10 FEET by 20 FEET

Ah-HA! I KNEW it! How the HECK did it get to be that big? Scale on the drawing is set to one inch = one inch.

The G-code looks somewhat correct- it's a pickup cutout. but it's got a little glitch, it looks like, in the left side.

So now I get to go find out how to reduce the scale by a factor of 16.

Thanks for confirming my SWAG on it being scale.

Could you upload the .dxf? I'll give you some cleaner code that should work fine.

Sure thing, here it is.

I am converting from pdf files, using the AIDE pdf to dxf converter. Must be doing something wrong there.

How wide should it be. The .dxf is 241 inches.

Yeow. The widest part of the hole, including the ears, should be 3.4 inches, and it should be 1.57 inches tall.

I already did it at 4" wide. Try this.

Make sure your I,J mode is set to incremental in Config>State

That's definitely much more like it in performance. Thanks for your efforts, Ger. I need to figure out why the scaling went wacky in the conversion, because the drawings are 1 to 1 and I told the conversion to go 1 to 1 as well.

I'll go see if a 1 to .1 conversion will do the trick.

Getting g-code from a .pdf is not a good way to do it. Notice how many lines of code you had vs what I had. Learn to use a cheap or free CAD program like A9CAD, www.a9tech.com , and you can do something that simple in a few minutes.

The sim says 7 minutes for my code and a minute 58 for yours. ;)

I've learned never to trust the conversions!

What pdf to dxf conversion utils are available , acfurate, and worth buying?

I definitely agree. I have CADSt lite, and A9CAD as well. My problem is I can't draw a straight line with a ruler;)

I have PDF's of what I want to cut in the dimensions I need them cut in, but you're right, I need to go back to square one and learn to use the proper tools.
