@DEFRAINE-JM Many thanks. I did find a stable combination after all, although not the latest version of the plugin or VSCODE, but I am happy that it works.

Hi @dan thanks for your reply. Actually not, also tried with an older VSC version (i.e. 1.25.1) but result is even worst (error: command pymakr.* not found and console doesn't start). Also downgraded Node.js to the LTS (8.12.0) but no luck. Because I'm using VSC for Python and to manage other non-pycom micropython-based boards via terminal it would be comfortable having a single IDE. Is there a particular setup known to work (firmware, VSC, Pymakr, Node.js, versions, platforms and architecture)? PS: Using Atom 1.31.1 on Win10/64 with Pymakr 1.4.4 I notice no issues, REPL responds correctly.

@dan Roger that!

@ralph when i press download into new folder (pymakr VS configured on COM port) all files are downloaded but 3 of them cannot be downloaded tried many times with reset, disconnect ... Downloading 3 files... [1/3] Reading lib/sensor.py Failed to download lib/sensor.py [2/3] Reading lib/konfig.py Failed to download lib/konfig.py [3/3] Reading lib/GPS2.py Failed to download lib/GPS2.py this is how it looks like in Filezilla: [image: 1520022712046-58fd99a0-71fe-41fe-920e-e93f3048132d-image-resized.png] Do you have any concept what can be wrong? - because e.g. file sensory.py is quite small name is also in lower letters without numbers - nothing special. konfig.py is really small file 696 bytes... I can of course do this by Filezilla but..
