@g0rg said in External driver, motor not working:

Although I don't think your issues are caused by using RRF 3.2 I would upgrade to 3.3 as much has changed between them (remember to read the changes). Specifically this point for RRF 3.3: "[Duet WiFi/Ethernet] When using extended step timings (M569 T parameter), maximum step pulse rates are improved a little"

How to say that the A axis has no maxima ?

You have define the A axis as a rotary axis using the R1 parameter so it should have no maximum.

How can i know what to put exactly in M569 ?

The information about the step pulse timing should be in the data sheet for your external driver. Also the enable logic (R0 vs R1) should be in the data sheet.

Also if you are not getting motor movement check the data sheet to confirm that driver is happy with differential signals at ~3.6V. The alternative is to us single ended with the + lines pulled to 5V;

@g0rg I would do something like this: (This is not real, tested code)

var xCurrent = 0 var yCurrent = 0 var xCount = 10 var yCount = 10 var xIncrement = 250 var yIncrement = 250 while yCurrent < yCount set xCurrent = 0 ; Start a new row at x=0mm while xCurrent < xCount G1 X{xCurrent * xIncrement} Y{yCurrent * yIncrement} ; Move to the new logo location set a GPIO pin to start the LASER logo burning while GPIO is not true ; Wait for the LASER to finish set xCurrent = xCurrent + 1 ; Move to the new location in X set yCurrent = yCurrent + 1 ; Move to the new location in Y
