Arduino uno with CNC shield v3 not working right

Patrick_2 · December 10, 2023, 1:37pm

So i have a Problem with my Arduino or the cnc shield

it connects with GRBL V1.1 with no issues but i cant Jog the Steppers but i cant move them they are locked, i´m using UGS to send the commands when i try to move a axis it just says ok and nothing happens
Arduino ide version is 2.2.1

Checklist:

Stepper power supply > 9V ?
EN pin matches your configuration?
signals for STEP/DIR/EN on the stepper drivers ok?
Stepper drivers OK?
Removed all jumpers?
use SANE values in configuratin (you don't have sane values now)?

.. checking your 4rd picture: most likely you "strange" values are the problem. Do the math and use SANE values - or the default values according to documentation.

Power supply is a 12v 10A
EN pins are set correctly
how can I know that the signals are fine ?
one jumper is left (Picture 1) top right corner "EN/GND"
never heard of SANE values

SANE in the sense of strongly emphasized "sane" in the meaning of "mentally sane" values. e.g. $120=0.000 sets the acceleration to 0m/s^2 --> no acceleration whatsoever --> no movement.

## Getting Started

First, connect to Grbl using the serial terminal of your choice.

Set the baud rate  to **115200** as 8-N-1 (8-bits, no parity, and 1-stop bit.)

Once connected
 you should get the Grbl-prompt, which looks like this:

```
Grbl 1.1d ['$' for help]
```

Type $ and press enter to have Grbl print a help message. You should not see any local echo of the $ and enter. Grbl should respond with:

```
[HLP:$$ $# $G $I $N $x=val $Nx=line $J=line $SLP $C $X $H ~ ! ? ctrl-x]
```

The ‘$’-commands are Grbl system commands used to tweak the settings, view or change Grbl's states and running modes, and start a homing cycle. The last four **non**-'$' commands are realtime control commands that can be sent at anytime, no matter what Grbl is doing. These either immediately change Grbl's running behavior or immediately print a report of the important realtime data like current position (aka DRO).

Solved it by reuploading GRBL and got a "fresh" install of UGS
But thanks for your help
