Was unsure if this was a bug until it was mirrored in another way until tried to print in ABS.
Using PLA, 185, 70.....Machine Control Panel to preheated temperatures are reached, even left alone for some time to verify stability, hit X Axis Home to keep from going to sleep. Sending gcode from either the Run button in the Machine Control Panel or tasking into the main program screen and sending the gcode to the printer. Everything seems good at fist glance but the Heated bed temp will continue to rise uncontrolled. While printing have to turn the Bed off let cool to less than 65, turn back on and the temperature will remain at the selected value.
ABS 225, 100. This is scarey but within seconds the extruder temp reaches 245. Wont start printing and have to hit Emergency Stop immediately.
Kinda dont want to put ABS through the Hotend again but will if you need to view the the data from the Communication window. Did notice a W? at the end of the command code line, if that's what you call it.
