Help needed - Unable to jog my CNC mill was created by MDP
I've been away from LinuxCNC for a while. I've been working on other projects. Fired my CNC mill up this weekend but the jog doesn't work and I can't run a program. I thought maybe my parallel port break out board had gone bad but I can move each axis using the "test this axis" feature in the setup wizard. I have a very simple home made machine with only and Estop and no limit switches. Could someone please refresh my memory on some troubleshooting ideas?
Thanks
Mike

-If it is a gantry machine with 2 motors on the same axis and 2 switches, it will not jog before homing
-check if the connectors are fully seated, parallel ports tend to seat crooked sometimes
-Does LinuxCNC get out of E-stop and can it be enabled
-do the drives have enable inputs wired
-check the power supply, might reset when drives get enabled and if yes, change the PS as it means the capacitors got dry and failed, do not use
-does the keyboard have arrow keys and are you using those to jog
-check the "Gremlin" the black preview where the parts are drawn, in front of DRO is there any sign
