General Mach Discussion / Re: Strrange sound of stepper motor Mach3

Hi there can I have one more question?
I am running my CNC with Mach3 and there is a thing like slowing down. But when I mill PCB board its doing kind of rounded corners. Is there a way to fix this?

Thank you

OK frends I have connected Mach3 with the main control unit "dont know how to call it in english its between PC and the drivers" so connected to my old drivers and its the same problem. So its the unit OR PC OR Mach3

On your question I am using version R3.042.020 and have no manual for my drivers I only found simmilar the rest just gessed but now I can see its not the drives.
My PC canot say what it is just found some old stuff and put it together will try my friends PC.

What you mean xm file? Mach3 settings? If so and its in the mach3 folder whats its name? Will send it.

Ye it could be because the chinese stuff.
Power supply:
I thing its not the power supply if I connect only one axis its the same.

I am going to try today my old drivers I made a long time ago with the rest of the present system hopely will see where its the problem.

The problem still remains even when disconected from rails

I have found now that when I increase microsteps its OK the higher the better but I need to run at lower speed and higher torque.
But still dont know whats causes this behavior.
Was thinking if its not something with Mach3.


More ideas?

Hello while I have builded small CNC
could you someone know what could be the source of strange sound of my stepper motors? Its like thud, thud every about 1 second sometimes not even every second.. all three axis. Even if I unmonted the rails and test only motors its the same. I am running on Mach3.
Was thinking maybe too long cables or something in electronic?

Power source 24V 10A
Drivers DM420A
Steppers Nema17

Thank you

General Mach Discussion / How to set a mechanical gap in Mach3

« on: December 05, 2016, 03:41:37 AM »

Hi guys, I am new here.
Have set up Mach3 for first time everything kind off OK. Now I have a gap or loose space on the axis like on the thread so the axis should always go a few steps when changing direction to skip this gap.
Do you know how to set up this in Mach3? Havent find this on net.
Or is there another way to achieve this?

Thank you a lot
