General Mach Discussion / Re: Motor tuning calculations
« on: April 28, 2009, 03:54:56 AM »

Don't know how I missed this Post, Been sidetracked a little with threading and other issues hear, Look's like you all need another opinion or two.

Nickle989, I think "Techsol" Hit the nail on the head as you seem to think also. So you should be on the way to resolving the Problem. I usually recommend setting all the Motor Outputs, Dir/Step Low-Actives to All the same State (checked or X), But in your case that may not be possible. If any of your motors run backwards you can use, Home & Limit's, "Reversed" to change there direction without re-wiring the motors.

To late for further comment, Maybe tomorrow.

Hi, Bruce

Try this xml, I changed your Active Low's and reversed step/dir pin's around in Ports & Pin's page.

Hi, Art

Hears 4 pic's of my good computer with simulated, 1, 10, 99 and 999 num slots.


Hi, Joe

What effect dose setting the pulley ratio up or Steps Per value up have on the start up speed.

I'm sure that someone with more exep. with spindle feedback will help you out, I know it can get quite involved, Just haven't been there yet myself.


Hi, Joe

In Config, Spindle Pulleys, Set a min speed value to start with, You may/will need to also set steps per value and vel, Accl values also in motor tuning.

I don't have spindle feed back hear, So not sure of correct procedure but it's a start.

Directions sound correct also, X- moves in deeper cut, Z- moves right to left tords head/chuck.

Hi, Art

I'll try it on my good computer in awhile, Using 2 non locked time sources, Need to find a divide/multiply chip and source off one timebase hear to test further.

Slot based RPM steady? Mine stays about the same as you's, 0.xx of 1 RPM. Flashes red/green when threading, Then red or green with rapids.

Hi, Art

Hears 4 more, 2 with 25 and 2 with 251 slots simulated.

Now if you'd make the "Corr" Barber Pole bidirectional, I'd have a Sync-Row-Scope to Adjust the ratio.

Hi, Art

Hear are some pic's to look at with simulated pulses single and simulated 4 slot doing G76 threading, Very Nice.

Seems to lock in the Pulse Frequency on my problem computer fine also.

Thanks, Chip

Hi, Kerry

In the Members Doc's section theirs a manual Rich has been working on in PDF format and lot's of info hear.


Edit: Hears a little template to look at, Where to layout your DXF's

Hi, Kerry

Make a copy of the LazyCam 3.00.2.exe you currently using/have in C:\Mach3 folder, The "update" has a older version in it, Don't now why.

You can copy it back in and Re Name it after you install the Up Date.

Download the latest ver LazyTurn, On page 102, post 1017, Un-Zip it and install the LazyTurn.exe file into C:\Mach3, You need to install the updated, LazyCam 3.00.2 Update also from Download's above.

You may need the, ".net 2.0 update" from Microsoft to prevent an error at start up also. Hears a link to it.


Hope this Helps, Chip
