Well,
the figures do not compute, the spec tells me it's 18.2V 11A which would
be max. 200 W.
But I thing 0.4 Nm is very low for this wattage.
As the spec also tells me it is meant for applications such as carriage
of high speed printers and XY plotters.
IMHO these are too small for a CNC router with anything bigger than the
smallest dremel or proxxon drill.
The Rutex card do not have any error outputs (none that I could find).
My best guess is that the motors are not able to do what they are told to.
Regards,
Rob
