Print Center is off

[Cox]

I cannot figure it out but my 3d view of the print has it at center but in the layer view and when I print it puts in like the layer view!

See attached:

MatterControl Layer View

This was after using the MatterControl AutoCal (which shouldnt effect it?)

So I did some extensive searching and found this. This sucks.... but my problem is fixed

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.

I just ran across the same problem. I don't know how to correct slic3r, however what I did was add the following to the gcode that was generated:

G92 X100 Y100

after the home command. I found that in mattercontrol if I set the bed center under options as 100,100 - that my print showed up in the center of the bed. However it appears this setting is only used to adjust the layer display, and has no affect on the gcode that is generated. Likewise, the G92 command does not seem to have any affect on the print displayed offset on the bed, but it prints properly.

On a related but separate topic, the reason I switched to slic3r instead of matterslice was that I had created an .STL file with my CAD software with multiple solids in it. I did this because editing an imported STL file wasn't really possible (it imported as facet bodies which I couldn't do anything to except pick up points on the surfaces). So I drew additional parts on top of the STL file and exported all the bodies into one .STL file. When I sliced them with matterslice or cura, it appears that both of them leave empty space where the two bodies intersect (in other words it subtracts one body from the other at intersections). Does anyone know how to change this behavior? Slic3r left the intersecting locations as if they were a single solid, and that was what I wanted to have happen.

Thanks!

Netfab may help with that. I've also had some luck using 3D builder on windows 10 for repairs like that.

Good call - the download basic version of netfabb didn't help, but the cloud version that is linked with microsoft removed the self-intersections. Thanks!
