[BUG] G29 failing when printing from touch screen about marlin

[NickDevoctomy]

Just to add, I'm currently looking at the source to see if there is an obvious fix to this. I tried preventing the ABL callback (that updates ABL progress) when the printing PRINT_PROGRESS_RUNNING page is shown but this did not work.

[NickDevoctomy]

Just to add, the issue appears to occur in this sequence,

1. G28, Homes just fine
2. G29, starts homing point 1, does both touches, then flies into middle of bed, then back out to < 0,0

[NickDevoctomy]

Any ideas how to get the SERIAL_ECHO messages to appear when initiating commands from the printer? When initiated from Octoprint I see them fine but not from the printer.

[NickDevoctomy]

I'm just testing the extui branch with alpha 4 lcd firmware to see if the problem exists there.

[NickDevoctomy]

Just run a few tests and it seems that it's not starting the print from the card, it isn't heating the bed & end, just sits there with the time going up at the moment.

[Sebazzz]

Do you have a log from octoprint or another host on this?

Please try this. My mainboard is unfortunately dead, so I could not reproduce it, but this might resolve it.

[NickDevoctomy]

Thanks @Sebazzz I shall give it a shot later on today. Unfortunately with respect to logs, nothing was coming back in Octoprint, so I started adding some additional logs, but these wouldn't show when printing started, only when running G29 separately. Is there a way to enable logging during printing?

[Sebazzz]

Yes check the release notes Met vriendelijke groet, Sebastiaan Dammann

firmware-20201108-125953-hotfix2.zip

If hotfix1 will not fix it, please try hotfix2 instead.

[NickDevoctomy]

Okay, so first hotfix appears to be working but it's dropped the temps during bed levelling, from 200 / 65, to 120 / 50.

[NickDevoctomy]

Once it finishes, it then attempts to print at those temps. Obviously that won't work as the filament won't melt that low.

[Sebazzz]

Level before you set the temperatures, for instance, using this gcode:

[NickDevoctomy]

okay, not sure that will work with Cura, as I set the start gcode, all of the temps are put in automatically before that. I'm not worried about drips of filament on the bed tbh, so I'll just mod my local copy of the source.

[NickDevoctomy]

Thanks for your help, this is great. You're a diamond.

[Sebazzz]

okay, not sure that will work with Cura, as I set the start gcode, all of the temps are put in automatically before that. I'm not worried about drips of filament on the bed tbh, so I'll just mod my local copy of the source.

When Cura doesn't detect any temperature placeholders, it will insert the temperature itself.

[NickDevoctomy]

oh thanks, I wasn't aware of temperature placeholders so I shall take a look at that rather than modding my source..
