how to calculate?

Hi Niroleta,

That’s the next thing to do when you have the machine moving under Mach3 control.

Rather than repeat the instructions here…

If you refer to Section 5.5 of the Mach3 Manual http://www.machsupport.com/documentation.php (I assume the French Manual has the same Section numbers) this details how steps are calculated manually. Then Section 5.5.2.3 details the automated process which is probably best for your machine with it’s reduction pulleys and drive belts etc. This process is then repeated for each axis in turn.

Hope this helps.

hello tweakie,

I got your message about the manual

Section 5.5.3.2 is the chapter on automatic settings in French.

Tomorrow afternoon I'll try to system setting.

In any case tweakie I want to thank you for the help you give me, and still grieve for my English.

I'll probably still need help then I hope you will always be there to help me.

Hi Niroleta,

I am pleased that you are making good progress with setting up your new machine.

( Your English is excellent and 100% better than my French  )

Tweakie Hello how are you?

I still need your help

This afternoon I tried cutting a rectangle with a circle in the middle.

The machining is very smoothly as you can see from the photos.











Now I ask you a few questions.

1 - why in MDI mode, when I type G01 Y-60 F1000 milling shifts the Y-60.0547 and G01 X-600 F1000 milling shifts the X-600.0199?

Here are some photos.







and I encounter the same problem with the machining of the part above.

in the program there are G01 X-120 F700 and the machine shifts to X-121.12.

that the dimensions of the part is not good agreement, but normally when I type in MDI G01 Y-60 F1000 machine must stop at Y-60 why it does not?

2 - How to reduce speed rapid traverse G00?

PS: For my settings automatic I use calipers square is what it is or should I use a dial indicator tip?

thank you in advance for your help

Hi Niroleta,

Mach3 will only make movements which are a multiple of your ‘steps per unit’  (as set in motor tuning).
Could you give some details of your motor tuning setup please ?

Hi Niroleta,

Sorry, my fault for not being specific.

If you could attach your Mach3Mill.xml file (located in Mach3 folder - it needs to be renamed to something unique before posting) - or details of your X an Y axis motor tuning from the Mach3 motor tuning page it would be helpful.

Tweakie.

I do not use machmill I use cnc611 in mach loader is the two files I paste in mach3

I send you machmill.xml or cnc611.xml or both?

I can send them to you via email?

Once again apologies - it is the 'CNC611.xml' and yes you can email it.

Tweakie.

I'll send you the file.

you can tell me is that you change in the file plz

Hi Niroleta,

I have sent you a PM with my suggestions.

Tweakie.
