please change the line endings of your terminal to LF and try again. It should be a pretty long multiline output.

edit: but i presume clearing the jam doesn't involve changing the firmware version; and i'd skip to the reset, clear and adding of wifi details before attempting to re-flash the wifi firmware.

how does one do this?

@bearer i ran the M122 code and this is what is spit out

@JoergS5 that did not work

tried the same steps and still failed while trying to connect to Pearce wifi module is idle

my printer jammed, so i took the nozzle off while it was running, cleared the nozzle and put it back on, then it reported a nozzle fault and now it wont connect to wifi anymore this is the first actual error message it has given me otherwise it was just saying

WiFi reported error: Failed while trying to connect to Pearce<LF>WiFi module is idle<LF>WiFi reported error: Failed while trying to connect to Pearce<LF>WiFi module is idle<LF>WiFi reported error: Failed while trying to connect to Pearce<LF>WiFi module is idle<LF>WiFi reported error: Failed while trying to connect to Pearce<LF>WiFi module is idle<LF>WiFi reported error: Failed while trying to connect to Pearce<LF>WiFi module is idle<LF>

im coming from printrbot so this a steep curve. any help would be appreciated.
