Hi, Charlie

Latest ver. Mach3D2.00.049, Has much better rot. view, It's what I am using.

Thanks, Chip

Hi, Graham

This put me on the right track, your file loaded just fine.

But after working through the editing and save options to use other files, I found the Real Culprit.

I use WordPad text editor from time to time, it has 4 formats for saving files, RTF, TXT, MS- DOS and Unicode, text Document save options.

Mach will load all 4 of them, But the Unicode Txt will not show in G-code Window or View, My default editor for Mach is set to Notepad.

So when I hit Edit "notepad" in Mach, it shows the G-code txt just fine, Mach doesn't completely recognize the Unicode Txt though.

Try this File Below, let me now what you think.

Thanks for the Help, Chip

General Mach Discussion / Re: Is there a difference between a pulse coder versus quadrature encoder?

« on: February 23, 2007, 02:41:47 AM »

Hi, David

It all depends on ball-screw ratio.

Not to disagree hear, but 2000 count encoders will work, may have to use 35k or 45k kernel speed on Mach to get the top speed back-up and might not archive the 300 ipm as before, speed isn't every thing.

How many turns of servo to move table one inch, I think I read another post where you stated that its a .0001 accuracy, thats a .8 inch per turn of servo / ball-screw ratio.

Lots of machines use 5 turn per inch ball-screws 200 steps per turn steppers gives them .001 accuracy, If it had a 8000 steps per turn servo I would agree.

Check your servo turns per inch, it all depends on ball-screw ratio.

Do plenty of research 

You can probably use your servo amps with +-10 volt to step / dir input cards there several out there.

Just another opinion hear.

Hope this Helps, Chip

Hi, Charlie

Yes your making sense

Look under Help "About Mach" it will tell you what Version your using Could be an eariler ver. of Mach3.

You can use one turn "Steps" and work it that way also, just not sure about the cut-speed you'll get though.

Depends on the reduction ratio of your rotary table.

Post your code, find out what ver. of Mack your using.

Thanks, Chip

Hi, All

Can someone please post the Proper use of M98 (subtest)file that's in
subroutines folder, as described in Mach3 manual.
Haven't been able to import it into Mach3.

I'm Using Mach3 2.0.049

Thanks, Chip

Hi, Charlie

It looks like a Mach2 screen you posted, Brett posted a Mach3 screen.

I was refereeing to Mach3 Settings Page in my post also.

Both will co-exist and run fine, I have very little experience with Mach2.

Thanks, Chip

Hi, Escowizard

Thy will co-exist and the license is good for both, I understand the If it ain't broke, for sure.

Thanks, Chip

Hi, Charlie

In the Settings window there is a Rotation Diameters section, Enter work Diameter for your axis there, helps Mach control F-speed.

Still need to set rot. axis in steps per degree of rotation, One full turn divided by 360 = steps per deg.

My steps per deg are 400.2, vel 2500, acl. 500, 10 micro step comtrol 144000 one full turn sherline rotary table.

Hope this Helps, Chip

Hi, Escowizard

Sorry should have commented on Mach3, while I haven't used Mach2 other than fire-it-up to help others, still haven't figured out activation

of 4th axis go figure!

I think you would like Mach3 allot as Art stated,  Rotational view is really nice.

Need a computer around 1000 Mhz, have run it on a 600 Mhz though.

Ive got a 4th axis running also, havent done mutch with it except "air cut" some gear teath.

If I can Help let me now.

Thanks, Chip

Hi, Escowizard

I don't understand why, if you haven't changed anything this would happen, is this a larger dia. than before.

Try putting F-speeds in the lines of code giving you problems.

I think A-axis takes over F-speed, maybe reducing your A-axis Vel setting and adjusting your F-speed will solve this.

Just some thought's, Chip
