What to do what to do. I will type in 100 mm & it will go 200 mm. Type in 200 mm & it go’s 400 mm. Wiring is right & tight. :-<
Probably your gcode settings is off
And how do I fix it?
$0=10 (step pulse, usec)
$1=255 (step idle delay, msec)
$2=0 (step port invert mask:00000000)
$3=3 (dir port invert mask:00000011)
$4=0 (step enable invert, bool)
$5=0 (limit pins invert, bool)
$6=0 (probe pin invert, bool)
$10=3 (status report mask:00000011)
$11=0.020 (junction deviation, mm)
$12=0.002 (arc tolerance, mm)
$13=0 (report inches, bool)
$20=0 (soft limits, bool)
$21=0 (hard limits, bool)
$22=0 (homing cycle, bool)
$23=3 (homing dir invert mask:00000011)
$24=25.000 (homing feed, mm/min)
$25=750.000 (homing seek, mm/min)
$26=250 (homing debounce, msec)
$27=1.000 (homing pull-off, mm)
$100=40.000 (x, step/mm)
$101=40.000 (y, step/mm)
$102=320.000 (z, step/mm)
$110=8000.000 (x max rate, mm/min)
$111=8000.000 (y max rate, mm/min)
$112=500.000 (z max rate, mm/min)
$120=500.000 (x accel, mm/sec^2)
$121=500.000 (y accel, mm/sec^2)
$122=50.000 (z accel, mm/sec^2)
$130=290.000 (x max travel, mm)
$131=290.000 (y max travel, mm)
$132=100.000 (z max travel, mm)
$102 is set to 320 (z,step/mm) I had an issue with my z not going deep enough so I turned it up. But also you should check the jumpers on your z if they are put in the wrong place is can multiply or divide your steps. But I am not fully sure about it. I am sure GlennMDutcher might know more.
I’m pretty sure you type $102=# which is half of the value of the original settings.
James,
Did you get your problem fixed?
Yes, Paul from Inventables sent a new board and now it works!!
