This changes the M140 command to M190 so that the machine waits for the bed to get up to temp.

Description

Previously machine would start printing before bed had reached temp. This was especially noticeable with high temp materials like ABS and ASA where we want the bed at something like 100 degrees.

Tests

If I manually change the gcode in my own user profile, it works perfectly. I believe it should be changed for everyone.

Could I get a sign off on this? @wujie-elegoo It would be awesome to get this fixed before 2.3 goes out. Otherwise I think Elegoo will be dealing with issues from people.

In the ElegooSlicer branch version V1.1.8.0, we made modifications and placed them after the M729 command for better performance. After thorough testing, we will also submit a merge request to orcaSlicer. Thank you

Since the bed levling is done at 60C, and the cool plate or B side only needs 30-35C, the M190 causes the printer to wait for a very long time (over 30 minutes) for the bed to cool down. What I've done now is to turn the aux fan to 100% to help cool it, drops the cooling time from over 30 minutes to about 10 minutes. I'll submit a PR later.

But the real solution would be for Elegoo to change the auto bed leveling to use the first layer bed temp instead of a static 60C. I have suggested here ELEGOO-3D/ElegooSlicer#28 , hopefully they'll make the change.

Agreed. While I haven't had an issue with leveling, it's not ideal to do leveling at a static 60c and then print at 100c just as an example.
