ShapeOko3 Grbl defaults?

Post by chamnit » Fri May 08, 2015 2:38 pm

Could someone with a ShapeOko3 post the Grbl '$$' settings for me? I'd like to add them to the Grbl repo defaults and place a pre-built binary on github.

I don't have an SO3, but I think you can bring up a serial terminal screen with CarbideMotion with an 'M' keystroke. Or connect to it through a normal serial terminal program.

Thanks!

Here they are from my S03. I did a ctl-x just before the $$. I have changed $100, $101, and $102 from the factory values, but I've changed nothing else. I neglected to record the initial values of $100 through $102.

Code: Select all

CarbideMotion 0.9g
 $$
$0=10 (step pulse, usec)
$1=255 (step idle delay, msec)
$2=0 (step port invert mask:00000000)
$3=6 (dir port invert mask:00000110)
$4=0 (step enable invert, bool)
$5=0 (limit pins invert, bool)
$6=0 (probe pin invert, bool)
$10=255 (status report mask:11111111)
$11=0.020 (junction deviation, mm)
$12=0.010 (arc tolerance, mm)
$13=0 (report inches, bool)
$14=1 (auto start, bool)
$20=0 (soft limits, bool)
$21=0 (hard limits, bool)
$22=0 (homing cycle, bool)
$23=0 (homing dir invert mask:00000000)
$24=100.000 (homing feed, mm/min)
$25=1000.000 (homing seek, mm/min)
$26=25 (homing debounce, msec)
$27=5.000 (homing pull-off, mm)
$100=40.020 (x, step/mm)
$101=40.020 (y, step/mm)
$102=40.020 (z, step/mm)
$110=5000.000 (x max rate, mm/min)
$111=5000.000 (y max rate, mm/min)
$112=5000.000 (z max rate, mm/min)
$120=400.000 (x accel, mm/sec^2)
$121=400.000 (y accel, mm/sec^2)
$122=400.000 (z accel, mm/sec^2)
$130=425.000 (x max travel, mm)
$131=465.000 (y max travel, mm)
$132=80.000 (z max travel, mm)​

The initial values for $100—102 were 20, since my machine was making stuff at half size before I made the same change you did.

So which is it? 20 steps/mm or 40 steps/mm for all of the axes? Is the SO3 set to 1/4 or 1/8 micro stepping?

As I recall, the steps in Grbl were set to 20 and my board at least arrived w/ the switches set to 1/4 micro stepping (and NEMA 17 motors, but we'll give a pass on that, since they were supposed to be that before the free upgrade).

I only got half-size stuff after I flipped the switch and before I fixed things (after two tries).

I am confused.
Do i set x,y, z to 20 or 40?

Also where are these switches and what do i set them to?

Thanks
K

The DIP switches are on the Carbide Motion board near the matching connectors.

The intended defaults are to have the switches set to NEMA 23 motors, 1/4 microstepping, and 20 for the $100—102 values.

Please adjust your machine as needed to ensure those settings if you wish to use the defaults.
