all 3 axes will not change direction - help needed
- On a new Sherline mill with Sherline driver and steppers, using EMC2 as supplied by Sherline, booted from the supplied CD, all 3 axes step properly but will not change direction - neither manually nor with g-code.
this seems to mean that pins 2,4,6 of the parallel port either do not receive the direction pulse or ignore it. the port is on the PC motherboard, not an add-on. Changing the port setup between ECP EPP BI-Directional did not help.
any idea how to fix this will be welcome
