Please could someone help :)
I have recently purchased a Smoothieboard (SB now) and have the following issues.
1) Power supply to Fans
Here i have connected 3 fans to a box that the SB sits in and 1 fan to the hotend.
These fans have to turn on when i turn the SB on.
I have a 12v supply connected to PWR_in next to the P2_6 (jumper 28 is NOT connected)
I have the Fans connected to P2_6
I created a fan1 to control P2_6 and tried all ways of setting this to pmw and digital
but cant get the fans to power on with the board.
Having m106/7 to turn the fans on and off works, but this is not possible to use as
they will be turned on and off when the PLA fan connected to P2_4 is switched by the software
to control this fan.
Any help here to be able to have the fans power on when i turn the board on and stay
powered on ?
2) Z-axis stepper motors (all in fact)
When i turn the SB on all the stepper motors are inactive, if i move the z-axis up
any distance that works, but then the motors keep humming (active) i have left it for 40+ minutes
and the stepper motor does not turn off.
If i run a print for 24 hrs then the z-stepper motors would seem to run for 24hrs, if
the print was 400 steps high then the z stepper should only be running for a total 7 mins
not the 24hrs.
The nema 17 are 1.7amp and i have the power set to .7 so its not an issue with over power.
How can i set the steppers to turn off when not active ?
Thanks for reading and i hope you can help
