Hi,
this post should be on the main Mach4 General Discussion board, it will get more views and therefore responses.
The USB board you have does not in all likelyhood have a Mach4 plugin and therefore will not work with Mach4.
This is a list of those manufacturers who do have motion control boards with a Mach4 plugin:
Warp9 TD, Ethernet SmoothStepper
Vital Sysytems, HICON
PoKeys, 57CNC, 57CNCdb25
CNCDrive, UC300,UC400,UC100
PMDX, 411,424 etc
CSLabs, CSMIO/P
XHC,....
These last two are hard to recommend, CSLabs have become very slow to address bugs in their Mach4 plugin, and XHC, the sole
Chinese manufacturer, is just so buggy and constrained I would avoid like the plague.
