Pause / Resume from DWC buttons - nasty head crash - but WHY?

SputnikOC3d

I suspect the fact that I may have executed a few DWC commands from the windows - may have caused the board to lose track of its location ? I didnt think it would but perhaps it does. Trying to search for answers ...

Done this a few times in the past but it no workieeee this time.

Hit Pause ... Print head moves - sits idle with heat still on...
Hit Macro - for releasing the Extruder Motor [ M84 E0 ]
remove filament - cold pull style - manually ...
insert new filament feed - press in till a bit of oozing [ petg 245*C ]
tweez off ooze
Hit Extrude for 50mm on the DWC panels buttons for Machine Control Window

Hit Resume .... [ i remember it used to work ] .... but alas, in this case - hard crash into part.

Looks like it was trying to go to gcode's beginning and print a Purge Strip.

Clueless in Cali

2.02RC5

You should not use beta or RC firmware versions once the corresponding stable release is available (2.02 in this case). As @resam said, there was a known bug in this area in some 2.02RC versions.

Thanks David ...

Lesson learned then. I wondered if I had changed something somewhere that may have caused it ... I had not had the printer up and working for over a month - and needed to get a friends parts printed ... asap. Didnt think to see if there was a new version before rockin and rollin. Lesson #2 learned

Im up on all the latest stable full releases now.

thanks to all for the assist.
