Slic3r started offsetting prints off the bed?

[jason128]

I made the mistake of hitting update to mattercontrol to 1.4.0..
now slicer seems offsets all prints off the top right of the bed.
Printer bed size is set correct at 280x280, circular and printer centre & extruder offset are botth at 0,0.

unfortunately i can't counteract the error by offsetting the printer centre, as it still tries to print well off the bed.

only happens with slic3r (which unfortunately is what all my settings are on)- matterslice is ok

picture of what it generates is attached and the start of the gcode for a 20x20 cube looks like this:

any ideas?

For the 1.2.X branch of Slic3r, they completely changed the way the bed is defined. It now defines a series of coordinates that draw line segments to build the bed periphery. The one it will generate for a 280mm diameter circle is as follows:

Code: Select all

bed_shape = 139.2331x14.634,136.9407x29.1076,133.1479x43.2624,127.8964x56.9431,121.2436x70,113.2624x82.2899,104.0403x93.6783,93.6783x104.0403,82.2899x113.2624,70x121.2436,56.9431x127.8964,43.2624x133.1479,29.1076x136.9407,14.634x139.2331,0x140,-14.634x139.2331,-29.1076x136.9407,-43.2624x133.1479,-56.9431x127.8964,-70x121.2436,-82.2899x113.2624,-93.6783x104.0403,-104.0403x93.6783,-113.2624x82.2899,-121.2436x70,-127.8964x56.9431,-133.1479x43.2624,-136.9407x29.1076,-139.2331x14.634,-140x0,-139.2331x-14.634,-136.9407x-29.1076,-133.1479x-43.2624,-127.8964x-56.9431,-121.2436x-70,-113.2624x-82.2899,-104.0403x-93.6783,-93.6783x-104.0403,-82.2899x-113.2624,-70x-121.2436,-56.9431x-127.8964,-43.2624x-133.1479,-29.1076x-136.9407,-14.634x-139.2331,0x-140,14.634x-139.2331,29.1076x-136.9407,43.2624x-133.1479,56.9431x-127.8964,70x-121.2436,82.2899x-113.2624,93.6783x-104.0403,104.0403x-93.6783,113.2624x-82.2899,121.2435x-70,127.8964x-56.9431,133.1479x-43.2624,136.9407x-29.1077,139.2331x-14.634,140x0

Unfortunately, it doesn't look like MatterControl will properly import a 1.2.X-formatted .ini file.

You could download a standalone copy of Slic3r, import your settings into it, correct the bed shape settings, and then use that copy of Slic3r to generate your gcode.

thanks for that- ive logged the fault, so hopefully they sort it.
i guess i'm either reloading the previous version of mattercontrol or using matterslice in the meantime.
I have to say- its nice how fast matterslice is compared to slic3er...
