Cura 2.7.0 won't slice with 'One at a Time' enabled

[GuusR 0]

Hi all,

I have a problem with Cura 2.7.0 stable. I want to print multiple parts with 'One at a Time' setting enabled, but Cura just refuses to slice. Settings for printhead have been set to a minimum to avoid the 'grey shadows' overlapping.

Cura does not give any visible warnings yet it doesn't doe anything when I press Prepare. It does slice normally when i have it in 'All at once' mode. Furthermore I have tested with just two models on the platform and having them as far away from each other as possible, still no slicing.

Here is an image of what I'm trying to slice:

Is there a setting I've overlooked or is this a bug in Cura?

Based on the assumption that their customers are too stupid to use the feature without hurting something, the developers intentionally disabled sequential printing in 2.7.

There is another recent thread that calls out a tweak to re-enable it for those capable of arranging objects on a buildplate.

@Eldrick, please keep your personal frustrations in check. There is no reason to assume that @GuusR is affected by the same issue as you are. As far as I can see OP is using a single extrusion printer.

@GuusR, can you post logs somewhere so we can see what is going wrong?

Please don't paste the logs here, because they will likely be very large and the forum will mangle the input. Instead, please post them on eg pastebin.com and post a link here.

I am also having the same issue, unable to slice when one at a time is selected.

Using single nozzle UM2 type machine but not using SD card instead generating Gcode and sending to repetier server.

I've found two issues in your log;

1. You seem to be using a custom fdm machine. At some point the head size had an issue with that, which caused incorrect data to be there. This should be fixed. Try readding the machine (and removing the old one)

2. When the wrong data got passed along, the rest of the code didn't handle that gracefully. I've just resolved that for 3.0

I deleted problem machine and recreated.

same issue.

are you saying v3.0 will fix this error?

Thank you,
