To update on my last post, I have finally confirmed the issue and solution. I contacted S3D customer services and received the following reply which worked like a charm... appears it was a firmware issue as you correctly predicted brian442: -dmsmith wrote:I managed to find the issue (see my post further up). I can have two files containing the exact same code but one with the commented command in and one with it omitted, and the one with it omitted works flawlessly every time. I haven't tried to send the file over USB as I've only used WiFi (SD Card option in S3D then sent over WiFi via FlashPrint) to date but will try this however I don't expect any different results - I could be wrong and will update you once I have tried. It's definitely a head scratcher!brian442 wrote:That sounds like a bug in the firmware to me. It shouldn't process commands that are commented out. In fact, I'm pretty sure those don't even get sent to the printer when printing over USB (were you having this problem with USB or from the SD card?)dmsmith wrote:If anyone can explain the reasoning behind this it would be much appreciated as it is a pain to go into every G Code file to delete that single piece of information prior to each print.
If you're still having trouble, it would be helpful if you posted one gcode file that heats the extruders correctly, and another one that does not. That should make it easy to compare the temperature commands.
"Hello David,
Thank you for your question. I am happy to help. From the comments on that forum post, it looks like it may be due to a firmware bug not handling commented lines properly. I would try adding the following line to your post-processing box in the Advanced tab:
{STRIP ";"}
This should remove all comments. If you try printing a file with removed comments, do you see the proper behavior?
