Upgrade problem 3.0 no preheat before print starts

[OldGuy57]

Upgraded my account and my software. No matter what I select or unselect the printer does not wait on the J Head to heat up before it starts trying to print.
It did this everytime in 2.2.2, once I upgraded to 3.x that feature no longer works.
I am using a Smoothie board and everything has been flawless until today when I upgraded.

Please ?

do you have the wait for temp to stabilize function turned on?

I'm having the same issue. The "Wait for temperature controller to stabilize before beginning build" is checked for both the extruder and the bed. This is on a lulzbot mini.

I don't have a lulzbot mini, but I'd be happy to take a look at the files for you guys. Can you post the old gcode file from v2.2 that worked as well as the new one from v3.0 that doesn't? That should make it pretty easy to review and find the differences

[garfong]

I've attached two files. One is gcode from Cura that works and one is from simplify. I'm not sure why one waits and the other doesn't.

Well I see what's wrong, but I don't think the stock profile for the Mini would cause it.

Just to be sure, try these steps below
1) Go to "Edit Process Settings", click Remove, and then select the "LulzBot Mini" profile to erase it
2) Verify that it no longer exists in your drop down list
3) Go to Help --> Configuration Assistant, and select the "LulzBot Mini" profile to reload it.

After you do that, try another print. I have a feeling it will work since I just tested here and it didn't produce the problem I was seeing in your gcode

Let me know if that helps!

I'm also having the same problem with the lulzbot mini. Mine though preheats the extrude fine but its not even heating the bed up at all, yet it works fine in Cura.

[JoeJ]

Again, please try the steps I outlined above. I can confirm 100% that it works after you do that.

First off, sorry OldGuy57, for hijacking your thread. It appears that our issue is separate albeit similar to yours.

Thanks JoeJ, that appears to work around the issue. After deleting the profile and redoing the configuration wizard, the gcode changed on line 235:

M190 S[bed0_temperature] ; wait for bed to finish heating
to
M190 S110 ; wait for bed to finish heating

I created a new process to see if the bug would come back and it did not. Thanks again.
