LazyTurn / Re: Maximum size?

Not that I know of.

If you read the manual you will see information on dxf files and how the drawings should be created.

Post your dxf file.

General Mach Discussion / Re: radius or diameter circle

« on: December 29, 2016, 02:59:46 PM »

The motors are rated at 439 ozin at 3.5 amps. Power supply is 36V & 9.7amps.
The drives are good for 24-50V 1.5-4.5A.

So to get the most overall preformance I would suggest you set the drives for say 2.8 amps. Can't get more than 36 volts out of the power supply but you will need 8.4 amps total from the power supply if all three motors are being used and that is under the max rating.

Set your drives for 0.1126 step angle / 3200 pulses per rev as that would be
micro stepping at 8X and FWIW over 10x is a waste of time and you have no setting for 10x)

There is no motor curve so the max torque based on the above suggestion will be below 439 oz in. Just tune as replied by Dave and see what you can get.

I'll guess axis travel will be around 40 to 60 IPM.
You will be leaving some headroom for cutting forces when you reduce the max velocity found.
It's not how fast you can go but rather the system power, accuracy, and reliability when machining that counts. That said, set feed rates in CAM appropiately for
your "system" and would suggest you experiment some to gain some experience.


Now as far as the motor tuning.......
Haven't the foggiest idea of the specs for those ball screws,if any gear reduction is used, the size of anything you will be moving with your setup.
That's why you need to RTFM. Look at the index and you will see what pages to read. Also you will find in the manual how to have MACH set the
steps/ per unit so you don't need to even calculate. Once you read that you will know how to use the spread sheet in members doc's.

Can you give me an example of when I should be using the diameter?

The Cut Circle Wizard specifically asks for the circle and tool diameter, but as Dave replied, we don't know what or how you are generating the gcode for your work. Your machine must be configured correctly and one of the  steps is Motor Tuning and Setup.

CNC is not plug and play and one MUST learn some things before using their machine. So I highly recommend you have a read of  the  Mach manual and also watch the videos.

rockrude,
There is a manual for LazyTurn in Member's doc's.
Everything you need know is in the manual so have a read before using LT.

Have you contacted the seller about your problem?
Are you using a licensed version of MACH?
Have a good read of the Mach manuals and also watch the Mach vidoes.

- Post your xml file.
- Post info on a manual for your drive.
- What version of Mach are you using.
- What is the make of or what kind of computer are you using?

FWIW,

Could be ringing on the pulse instead of a nice square wave signal.
Check with an o'scope.

Another Chinese Drive ( never heard of the one you listed)?

If bad pulse from computer solutions are limited.
But make sure everything is configured, wired , etc.  correctly for what you have.

Post what was requested in my reply and others may respond.

Relative to machine info provide a link to the exact machine you have.
( Do not expect someone to spend their time looking through 15+ machines wondering what you have)

If you have questions please post them in this thread.

Mach Screens / Re: Where are button scripts stored?

« on: December 21, 2016, 02:41:01 PM »

I use Dietz's Machscreen so can't answer any questions on using screen4.

In Mach3 you can edit or add scripting by Operator>Edit Button Script,
the buttons available to edit will blink, click on the button,
and the editor screen will show any scripting. Make changes as you wish
and when you click to close the window  you will be given choices on what to do.....one of them is to save the changes.

The changed script is saved in the screen set. If you copy that screen set, say to another computer you will see the scripting.

Frankly to learn, I just copied the Mach3 folder to a computer and started playing around with a screen learning how to use what's available in the screen designer program. It was rather intuitive to me on what is required to do things.

Now as far as scripting goes .......... thats a different story.
You can start by reading ( no lets say studying ) the following:

- Mach Customization Guide
- Mach Programmers Reference Manual
- Get posted list's of Buttons, DRO's, Led Numbers, etc.

Then if you have no experience with programing / scripting:
Go STUDY examples posted of scripting, what's in existing screens, pay attention to how things are done and before you know it you'll be dangerous!

Have fun ....it's a trip!
