M3 movement question

[easyar15dotcom]

Hello CNC Pros,

Background: When running a two sided project recently, I was creating some dowel holes to align the material to the spoil board.  I noticed that the gcode only drilled part way through the piece.  I checked and re-checked and re-checked my CAD files and sure enough the design showed .60 depth on my .50 board (no warping, etc).  I then ran simple one inch jogs on the machine for X, Y, and Z and saw that X and Y were correctly moving, but Z was moving in half inch intervals.  I used both UGS and Picsender and verified the same results making sure my movement increments were set to 1".

Question: Is there some sort of $$ setting that I can manipulate to view my Z movement distance?  If not, is there any other way to view/manipulate X,Y,Z movement?

My specs:  Using the M3 and designing with Vectric VCarve Pro Desktop.

Including both SVG and DFX files of a test for you Vectric users to verify my depth.

Test for depth.svg (2.58 KB)
Test for depth.dxf (9.53 KB)

Thanks guys!

Can I take a look at your settings? Just type that $$ in the command line and press enter then copy and paste it here.

Here are the $$ settings for two different gcode senders (GrblPanel and Source Rabit). Thank you in advance for taking the time to look at this!

Grbl Panel:

$0=10 (step pulse, usec)

$1=255 (step idle delay, msec)

$2=0 (step port invert mask:00000000)

$3=0 (dir port invert mask:00000000)

$4=0 (step enable invert, bool)

$5=0 (limit pins invert, bool)

$6=0 (probe pin invert, bool)

$10=2 (status report mask:00000010)

$11=0.010 (junction deviation, mm)

$12=0.002 (arc tolerance, mm)

$13=1 (report inches, bool)

$20=0 (soft limits, bool)

$21=0 (hard limits, bool)

$22=0 (homing cycle, bool)

$23=0 (homing dir invert mask:00000000)

$24=25.000 (homing feed, mm/min)

$25=600.000 (homing seek, mm/min)

$26=244 (homing debounce, msec)

$27=4.000 (homing pull-off, mm)

$100=40.000 (x, step/mm)

$101=40.000 (y, step/mm)

$102=40.000 (z, step/mm)

$110=8000.000 (x max rate, mm/min)

$111=8000.000 (y max rate, mm/min)

$112=6000.000 (z max rate, mm/min)

$120=250.000 (x accel, mm/sec^2)

$121=250.000 (y accel, mm/sec^2)

$122=500.000 (z accel, mm/sec^2)

$130=264.000 (x max travel, mm)

$131=264.000 (y max travel, mm)

$132=69.000 (z max travel, mm)

ok


Done



Here is the $$ from Source Rabbit (not sure if there is a difference or not).

[Bruce]

Did this get resolved? What machine are you using?

[Derek the Admin]

Thanks for checking in on this Bruce. I think we we covered this with him via support email if I remember correctly. It’s an M3. The Z steps per mm were 40 instead of 80. The accel and velocity was off too.

[rowiac]

Out of curiosity, what are the correct $$ settings for the M3? Mine is working fine, but it would be nice to know in case I needed to troubleshoot something. It seems weird that easyar15dotcom's settings were different than the default M3 ones. How would those get changed accidentally?
