UGCS alarm mode: Steppers moving incredibly slowly

Hi there,

When I initially set up my x carve - i ran the setup through Easel and everything worked great aside from a mis aligned Y axis. Since then, i copied the recommended settings into Universal G-code sender.

This is a copy of my parameters:

$0=10 (step pulse, usec)
$1=255 (step idle delay, msec)
$2=0 (step port invert mask:00000000)
$3=0 (dir port invert mask:00000110)
$4=0 (step enable invert, bool)
$5=0 (limit pins invert, bool)
$6=0 (probe pin invert, bool)
$10=0 (status report mask:00000000)
$11=0.010 (junction deviation, mm)
$12=0.002 (arc tolerance, mm)
$13=0 (report inches, bool)
$20=0 (soft limits, bool)
$21=1 (hard limits, bool)
$22=1 (homing cycle, bool)
$23=0 (homing dir invert mask:00000011)
$24=25.000 (homing feed, mm/min)
$25=50.000 (homing seek, mm/min)
$26=25 (homing debounce, msec)
$27=3.000 (homing pull-off, mm)
$100=40.000 (x, step/mm)
$101=40.000 (y, step/mm)
$102=188.976 (z, step/mm)
$110=100.000 (x max rate, mm/min)
$111=100.000 (y max rate, mm/min)
$112=50.000 (z max rate, mm/min)
$120=10.000 (x accel, mm/sec^2)
$121=10.000 (y accel, mm/sec^2)
$122=10.000 (z accel, mm/sec^2)
$130=790.000 (x max travel, mm)
$131=790.000 (y max travel, mm)
$132=200.000 (z max travel, mm)

Now everytime i load up any gcode software, the machine is in alarm mode which i have to override each time. Now when i jog the machine the movement is so incredibly slow. I have no idea what i’ve done and why all of a sudden its so slow and is always in alarm mode. Can anyone help out? It’s very much over my head.

Edit: I mean slow like, hard to tell its moving slow.

Your parameters are not correct. See below.

You are coming up in the alarm state because you have homing enabled and you have not homed your machine.

The defaults in the thread below are for the 500mm machine. For the 1000mm change $130 and $131 to 790.

Take a look at this thread:

You are a God amongst men Larry. Cannot thank you enough man!

Just been around the block a time or two. :smile:

Also these are wrong, thats your max feed rate limit, it should be 8000 on x and y and 500 on z, also your accels are super slow too.

$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)
