Logic for "wait for temperature to stabilize before build"

Hi,
I have just started to use simplify3D version 4 on a Mac and was given process settings for a flash forge and Wanhao by a colleague.

Flashforge worked perfectly but I had problems with the Wanhao, eventually I realised the Wanhao was printing before the extruder and bed temperatures had been reached.

On investigating further the process settings for the flash forge had the tick box for "wait for temperature to stabilise before beginning build" under the temperature tab cleared, whereas the Wanhao was ticked.

I would have expected the tickbox to be checked so that the printer waits for the temperature to be reached before starting printing.

I cleared the tick box in the Wanhao settings and the printer now waits for the temperature to be reached before starting to print.

cheers

Steve

Re: Logic for "wait for temperature to stabilize before buil

If you put any temperature control code in your startup scripts S3D ignores the settings wait for temp. (wish this was a little more obvious) There are a lot of undocument things I am finding
your start script must then contain the gcode commands.
M190 S[bed0_temperature] ;wait for bed temp
M109 S[extruder0_temperature] T0 ;wait for extruder temp

This got me the first time I did any customization. The default setup warmed both extruder and bed at the same time. Which typically is not a good thing.
