Z access only goes half way across work area to zero

After initializing to home and press jog to zero to lower left corner it goes about half way across work area and then stops it’s a 2019 xxl

What does the “Position” readout read when it gets to the center of the work area?

Did you configure for the correct machine?

Is this an older machine with a white control board?

X is at0.394 yis at2.756 z is at0.000

5

X is 0.394 y is 2.756 z is o.ooo

Did you use the Rapid Position (C), or the Rapid to Current XY? With Rapid to Current XY it should read X0.000 Y0.000 Then you need to jog to your desired zero position & set zeroes.

Or are you saying it stops before it gets to X0.000 Y0.000??

7

I am set on the correct machine.and I don’t know what type of board .

8

rapid to xy now it’s reading 0.000 but still does same thing

9

It does stop before 0.000

10

I can move it to 0.000 not on rapid.but not to my lower left corner

11

I’m thinking change belt

check Will’s suggestion first.

If you can’t jog left or forward from that rapid position, try going to MDI & entering

$20=0 to disable soft limits, then try to jog again.

Open the log, and MDI $$ to see all the GRBL parameters.
$130, $131, $132 – [X,Y,Z] Max travel, mm
These should match the physical limits (or just slightly smaller) for your machine

Reset $20=1 to enable soft limits after it’s resolved.

13

How do I get to soft limits.?

14

And where do I enter $20=00

15

On MDI tab (Manual Data Input). You can type GRBL commands & G-code manually.

For the next step, if that one doesn’t work, (or even if it does). Go to the Setup tab & find the button to show the log. Then MDI the “$$” to list all the GRBL parameters.

If the correct defaults don’t work on a recent machine, check in w/ support@carbide3d.com

Are you using the latest version of Carbide Motion? And if so, can you share the text data in Settings>Debug?

FYI the GRBL settings $130-132 are not used to limit travel in Carbide Motion, it’s a setting saved on the computer, not the Shapeoko controller. If you have soft limits enabled, the GRBL settings will halt the machine at the preset limits, but it shouldn’t be used.

Good to know. Tim, ignore my comment about turning the soft limits back on. (although if they were on, turning them off might help.)
