i need to increase my homing speed , its a crawl at the moment

thank you very much , i have it all working now , setting up the homing was the key

how setting first time my dual Y axis at setup wizard, i has try add my parallerport pin 8 and 9 is A axis, and setting pins 8,9 to tandem Y step and dir, normal Y have pin 4 Y step and 5 is Y dir, but no working. what i need setting can use 2 motor Y axis. new version 2.9.4 old has 2.8.4.

how setup dual Y axis, just installed new version linuxcnc because i hear support dual Y axis motors, but now first time try setting wizard make tandem Y step ad dir add to pin 8 and 9 (A axis in card) no working.

If starting fresh using the Stepconfig wizard in 2.9, don't use the "A axis" settings to configure your secondary Y axis joint. Start by configuring your machine as a XYZ machine, then choose "Tandem Y Step" and "Tandem Y Direction" for the step/dir output pins for the secondary axis on your parallel port. Similarly you must configure a separate home switch for both Y motors using two input pins connected to "Home Y" and "Home Tandem Y" (or one of the available combined home limit options available with those pin input options.)

If you already had a functioning configuration with version 2.8, you should be able to import the configuration files from that and have them work with 2.9 without needing to make any significant changes. (Maybe I think.)
