BZT - A Poor Quality Machine

[fidia]

I will take a picture not of the inner electronics. I do not think it has this board

You could send your cnc.ini file to the designer:

He might be able to tell whats wrong.

Or ask a question (in english) on this forum:

BZT have their own parameters that you copy to the CNC 4.01 folder when installing the software and the USB driver.

To reintall the firmware I assume you mean take out the board download latest version and write to board via USB?

[DuffelBuffelWuffel]

yes
You do not have tu "use" their values , this is just a "simple" 3 axis cnc , it is not rocket science. It might be something in their settings file that might cause the explainable "stall".

Checking the stepper wires / other connections is also wise.

The wiring seems OK as it runs OK when started up fresh. The problem only happens a few mins after running

[DuffelBuffelWuffel]

Yeah... I would contact bart eding on that subject .. this is quite weird
It also might it be that there is a bad connection and vibrations / current draw are causing the stall / step loss issue.
I would just check the resistance of the wires.

[fidia]

Will do now.

Just taking the boards off first
