Hi Irving,

Thanks for the above info. The penny has dropped !
I am working on a PCB using the L297 and L298, which is quite inexpensive in south Africa.
The size of the desktop engraver is only 400mm x 400mm with a Z movement of around 50mm.
I will first do a lot of testing and measuring before final set-up.
The next engraver is already planned. For that I will use more conventional drivers, maybe from the UK.
(the Rand Pound exchange rate is now around 18 / 1.)
Your remarks and positive information is very much appreciated.
