Have a YOOCNC 6040 setup running MACH3
with the YOOCNC 450JKB controller.
Recently (finally!) installed limit switches only to find
the "Y" axis input does not work. Can't seem to find
anyone selling these boards - (old and obsolete yes)
Or is there a replacement upgrade board I can get?
Using a UC-100 on this parallel interface and it works
great as is. Thanks in advance for any input.
