can mach3 burnout transistors on a CNC control board?

[irving2008]

Does MACH3 drive the axis faster than the old software?

MACH3 on its own cant blow up a transistor but it could potentially stress the system more as it is far more capable.. High deceleration rates will generate much higher back EMF (Robin's clonk) and if that happens on two or more axis simultaneously with a older less regulated power supply the surge could take out older transistors which may already be running hotter than designed for due to MACH3 working them at a higher duty cycle..

hi
gave it another go today on a little 4" x 6" carving, just using the easy cnc software that it came with and it worked perfect,
reading what irving's wrote think that's it, so will leave mach3 alone, and look for a code converter,




here's a photo of the board robin, arrowed are the bits that blew, plus a Darlington transistor that was on another little 2"x2" board that was joined to this by the yellow and pink wire,
don't know if there's diodes or not, didn't know what the other little bit was either, but the lad at maplins said something about resistor,
