Z axis wont' register correctly in marlin March 02, 2020 09:54AM |
Hi
I'm using marlin 1.19+bugfix and trying to set the steps/mm on my axis. I have succeeded in setting the X.Y axis correctly but I can't define the movement of the Z axis. When I make 10mm move the axis only moves 5mm.
The command that I'm playing with in marlin is
#define DEFAULT_AXIS_STEPS_PER_UNIT { 160, 160, 16000, 1000 }. I'm using a 0.9deg motors, M5 thread rods and DRV8825 motor drivers. All jumpers on the ramps are on so the the driver microstepping is set to 1/32. Using the reprap calculator I find that I need to set the value for the Z axis to 16000. So far so good.
The problem is that although I set the Z value to 16000 in Marlin when I send a M503 in pronterface I get the following:
echo
teps per unit:
echo: M92 X160.00 Y160.00 Z8000.00 E1000.00
Why isn't the value 16000 written correctly and I get 8000 in pronterface ?
As a matter of fact I always get 8000 whatever value I put in DEFAULT_AXIS_STEPS_PER_UNIT
