Re: Cura and M2?

[Dig]

I currently use cura because i like the way that it creates its tool path, when i preview the current slic3r tool path in comparison, it seems to use an algorithm that does a lot more moves to perform the same operation. a little inefficient. with a few programming tweaks slic3r could get there though.

i also like the skin option in cura, a higher exterior resolution but faster printing on internal perimeters due to a doubling of layer height.

what i like better about slic3r is the control on support material and the number of support and infill options that i haven't been able to get with cura.

it would be cool if thetr were a site with downloadable slic3r and cura profiles for the m2. specific profiles that work well for printing hollow, w and w/o support matl, printing small detailed solid infill objects, etc.

they both have their benefits.

I finally got Cura calibrated enough to do a real print with it, and it gave me my first hot-end jam.  After a bit of disassembly, it looks like it must have done a really long fast retract after the first 20 minutes of printing.  The jam turned out not even to be in the hot part of the hot end--a piece of melted filament had retracted all the way to the printed part that holds the idler pulley, etc., and bonded right to it!

I haven't bothered to go through the gcode to find the error; the print up to that point wasn't nice enough to make me think it'd be worth the bother.  I'll stick with slic3r or kisslicer for now.

Just looking for feedback on using Cura with the M2 and how clean the prints are.  Im curious because it seems like an easy-to-use, all-in-1 tool for printing.

Thoughts?

Chang,

I attached my cura .ini that works good with larger hollow objects. You may want to lower the print speed If you're printing smaller objects.

You are going to want to download and use Pronterface to print with and only slice with Cura or slic3r.

You need to set your e steps in cura under file/preferences.

When you connect to your printer in Pronterface you will see a value for E of around 235, punch that into cura.

In Pronterface you can monitor your temperatures (actual numbers) and extrude a few times in preparation for printing before hitting the print button.

An update on my Cura experience: Printing hollow with cura is giving me great fast printing results but it seems to be laying down too much filament whenever it does solid infill. I may need to raise the packing density to compensate for overfilling but still experimenting.

Hi, I am also trying out Cura with my new M2 but without any success - can anyone help?  I have been using the Pronterface/slic3r but there are some things(i downloaded from thingiverse) that slic3r fail to generate correctly.  So I turned to Cura and installed it as instructed.  I tried several simpler things which slic3r failed to slice correctly and with Cura, managed to see the objects in 3D (slice by slice animated in the display window) up to this point it works well and when I click 'print' printing will start after going through the starting process but the printing stopped at the first layer with an error code : No checksum with Line number.  'Error: No Line Number with checksum, last line : 31...........

The STL > Gcode part is okay but when it comes to printing, it always stop midway (in fact always on the first layer).  Where did I go wrong?  Anyone experience this.  I installed Cura 12.12A on my Windows 8 notebook (with Arduino drivers <ticked> during installation).

Thank you in advance.
