That is not normal.I find that I need to reflash GRBL to the Uno each time before I start UGS.
You are running a very old grbl version. Download the latestI end up with "Connected to Grbl 0.9j.
To get things moving, you don't need the UGS wizzard.So, I start UGS and use the Setup Wizard. Step 1 is to connect, which works - I end up with "Connected to Grbl 0.9j.
UGS don't need to know this, the grbl controller knows the layout of pins.Early in the project I was curious how UGS would know which pins I chose on the Arduino for step and direction.
The settings can sent to the grbl controller as a plain text fileWhat format is is that file?
Grbl has a very good WiKi to get started https://github.com/gnea/grbl/wiki
I suggest:
- you upload the latest grbl version (1.1f or later)
- don't configure it using UGS
- Use UGS to try get things moving
- If the steppers then don't move, check if you can move them by hand
- post your configuration
- post your wiring
- check if the drivers get warm (that means current is flowing and it is a good sign)
- check if you can rotate the steppers by hand if they are not moving
- post a UGS screen shot
