Control/Slicing software survey and help

[cloneit3d]

I just finished my printer yesterday, finally, and loaded up a file that I can print in 10 minutes on my home brew Cartesian printer using Cura. I loaded the part using Matter Control and print time is 37 minutes. I adjusted the speed settings upwards compared to settings used in Cura and print time does not seem to vary much at all. The importance of time when printing this item is I sell it in quantity. I settled on Cura for my other printer because dimensionally the parts seem closer to the CAD drawings verses Repetier, which was the other control slicing software I had used previously. Any wisdom in regards to the printer and Matter Control and what other folks are using and what there experiences are.

I am printing the part in PLA
Solid infill
I run a Smoothie Board on my other machine so maybe I am up against the processor on the Rambo?
Also I am tethered via USB right now to my laptop.

Thanks you, in advance, for your input.

I'm thinking it's probably a lot of little things, like the jerk values, as well as minimum layer times working against you time wise. You can potentially change the slicing engine under mattercontrol to CuraEngine, and see if that helps as well (As Matterslice may have created a highly pessimized set of paths).

Yep, either jerk and acceleration or minimum layer times. Maybe both.

If it's jerk and acceleration, you can either increase them and see if your quality declines or look at your model and print settings and see if you can make slicer setting or model changes to minimize abrupt direction changes. Sometimes if extrusion direction isn't critical even rotating the model so the extrusion goes parallel to the sides of a rectangle instead of corner to corner can make a difference.

If it's minimum layer time, you can decrease it and see if quality declines or you can just print more than one at once. If the part is such that it can be printed in more than one orientation, choosing the one that minimizes Z height helps with this too.

Layer height also makes a huge difference since the number of layers printed is height divided by layer height. You can do about 80% of nozzle diameter safely. The thickest layers that provide acceptable surface finish and the required detail resolution will cut time dramatically.

Thanks for the tips- minimum layer times seem to be the culprit. Now to work on other settings for print quality-which is terrible at this point.

Cheers!!!
