After getting it started, though, the lathe x or z axis will not move. I suspect that it might be because there is no provision in the stepconf wizard to define the x and z enable signals? If I manually edit the file and add these lines the program is extremely unhappy and will not start. :-\

EMC crashes when trying to launch the configuration generated by the wizard but I can still launch with my previous config files
Is there any reason not to just run with the previous (working) config files?

Andy-I wanted to use the wizard because I just replaced the 10 pitch leadscrew on my CNC conversion lathe to a ballscrew with a strange pitch and I thought it would be easier to set up and tune it with the wizard.

Some forum searching/reading seems to confirm my suspicion that I get no motor drive due to no xenable or yenable entries in the config file created by stepconf.
Should be an easy fix then. If you want to pastebin the hal file we can have a look.
Actually, it would have been a simple case of editing one parameter in the INI file.-I wanted to use the wizard because I just replaced the 10 pitch leadscrew on my CNC conversion lathe to a ballscrew with a strange pitch and I thought it would be easier to set up and tune it with the wizard.

Is there a way to make HAL and ini changes manually and "fool" stepconf into thinking there has been no manual editing?

I just about have things configured to my liking. I think that maybe stepconf has a bug or a shortcoming. With the older EMC I manually edited the HAL file for the xenable and zenable values and stepconf appears to use amplifier enable and does not offer the ability to assign which pin to which axis since they all get written to the HAL as xenable.
This is a bit odd, and I can't actually think of any reason to have separate enables for each axis.
Note that the signal names (the first word after a net command) are actually completely arbitrary and have no meaning at all to EMC2.
I thought that this had been sorted out though.
In most cases using axis.0.amp-enable to enable all amplifiers will be perfectly sensible and OK.

1. Can I make this manual HAL edit "stick" so future stepconf sessions doesn't wipe it out?
2. I did not see anywhere in stepconf where backlash can be specified and do not see it in the .ini created by stepconf. Is the backlash parameter somewhere else now?
Thanks for the help!

That is more economical in pins. Alternatively just put all the pins to be set on the same net line as the one that works.I suppose I could get into my driver box and wire the enable lines for all f the driver boards to one enable signal.
No, but you can put extra HAL in custom.hal, and that won't be over-written.1. Can I make this manual HAL edit "stick" so future stepconf sessions doesn't wipe it out?
delsig yenable
delsig zenable
net xenable parport.0.pin-YY-out parport.0.pin-ZZ-outI think backlash counts as "advanced configuration". You can add it in custom.hal too.I did not see anywhere in stepconf where backlash can be specified and do not see it in the .ini created by stepconf. Is the backlash parameter somewhere else now?
Personally I just accept that stepconf gets a config going as a one-time thing, then edit the more advanced stuff in by hand.
Once you get used to HAL is is fairly simple, and immensely powerful.
