Try to tick invert checkbox on X,Y and Z step output pins.
Maybe I should be a little clearer on this.
Recent versions of stepconf uses double-frequency stepping. The default
setting in Stepconf leaves the step pins for L297 in the wrong idle state.
When a DIR change is issued the L297 will

Would serial_dac.comp be a good starting point for making a SPI.comp or
do you recommend anything else to start from? Maybe there is something
written already?
If reasonable I would like to send more than one half bit per BASE thread

I am talking to a PIC18F4520 so 8 bits at a

Tried the CVS version 2.3.0 beta2pre. Could not find this double frequency
stepping implementation there either. This was a bad idea or is it replaced
with something else?

Hi list,
In stepconf there is a preconfigured setup for L297 with parport hardware.
I think it should out-invert all step pins, otherwise it will not work
with parport-reset quick pulsing.
L297 needs step to be high when dir changes.

Lars
Hi List,
Seems my version of stepgen (2.2.8) does not have parameter
stepgen.0.doublefreq.
Can I fix that?
Regards,
Lars
