Tommylight Thx for giving the hint about a motor cover...
Ugly fix but working (I am not proud of it) , I used cut off resistor legs as replacement for the broken conductor tracks.(other side)
I am quite happy to have bought Mesa cards! Good choice!
I hope PCW is surprised what his cards can do..... (just kidding)

Well !! hf discharges are spectacular but do not do much damage. the important thing is to clean the carbon residues well, maybe even remove the connector to clean better.

Sorry, I should have suggested a Buildbot install...
Those messages about missing parameters in the .cfg are only for information, they won't affect anything and will be populated if you click Save on the panel.
I am glad you are up and running, now for some fine tuning.

Oh now you're making parts ! Show-off !
Nice, glad you got it working.

I changed my single wires which connect my limit switches for cat5 cables. (I love those) Looks much neater when they are not singled.
Fine tuning will start now(a hint where to start?), shops are closed here and I can't buy sheet metal.
I am using post processor for fusion 360 so I will need to get aquainted with gcode and how kerf width is compensated. Still a long way to go.
I appreciate your help very much.
Thank you

The longer version would be deciding what will you be cutting mostly and fine tuning those cut parameters, again it will require testing, but after a while you get a rough idea of what should be cut with what parameters. Look for clean and dross free cuts on the underside, or dross that is easy to remove. While cutting metal, look under the sheet and check that the arc is in front of the cut by 5 to 15 degrees.
It depends a lot on the material composition also, so there is no exact recipe.
