General Mach Discussion / Re: mach3 randomly doesnt follow the correct toolpath

Hi John,

By popular opinion version .062 is the one.

General Mach Discussion / Re: Nmotion Controller

I am not aware of any endorsement for this product by Artsoft - sounds like a bit of deception by the vendor in the sales description of the product.

Ideally you should contact the vendor or manufacturer of the product you have purchased for after-sales support but as others have found that support is sadly lacking in the cheap far-eastern products.
However, I have attached a copy of the usbmove.dll which I hope will enable you to proceed.

You have nothing to apologise for, it is a damn fine bit of code

I second that - excellent work Thomas.

Hi Gordo,

Your Gcode file runs through to the end just fine here so nothing wrong with that.

We had a similar problem to the one you are describing some years back when graphics memory was limited. If you are up for a bit of experimentation then try turning off the Toolpath Display (Diagnostics window) and running your Gcode file again. If it completes successfully then it indicates that you need more graphics memory.

Now that graphics cards with 1 Gig or greater are cheap and readily available perhaps fitting one of those would be the way to go.

Hi Mesp,

Some CAD/CAM software's create arcs in Incremental Mode whilst other create arcs in Absolute mode ( you would need to Google it but the difference is basically the positioning of the centre of the arc ).
The IJ Mode setting within Mach3 is Modal so to be sure of the correct outcome all Gcode files containing arcs should specify the Mode (G90.1 / G91.1) as appropriate. This way you can run Gcode that has been created with any CAD/CAM software without encountering the problem you had discovered. Look at the Gcode of the smiley, it contains G91.1 so I knew it would run OK on your setup.

General Mach Discussion / Re: Steppers have no torque.

Do they have ferrite magnets?

Absolutely no idea.

I will contact Sonceboz and see what they have to say about the lifespan vs. torque of their motors - I think they only make round case types.

The old round stepper motors relied on ferrite magnets for their power. After 5 -10 years the ferrites lose their magnetisation and the stepper motor loses its torque. I have a large box of old round stepper motors of all sizes ...

I hope not.   

All my steppers are round case and most, if not all, are now more than 10 years old. 

Perhaps there are Steppers and there are Steppers (mine are Swiss made, Sonceboz).

Hi Mesp,

Try this Gcode file.

Tweakie.

EDIT  Just spotted the problem...

In Config / General Config change the IJ Mode to Inc. then Regen Toolpath.
In general all Gcode files containg arcs should include the G90.1 or G91.1 (as appropriate). For your Gcode file add G91.1 on a seperate line at the start of the code - your circles will then become round.

If you .zip then attach your Gcode file it can be checked for errors.

Which motion controller are you using (make and model) ?
