Well stated.
I've always leaned more towards the mechanical side of things just because I found it came easier to hand, whereas the electronics and programming side always required a lot of hard work to make even minimally acceptable progress and it always seemed I took the long way around the barn to get to any goal. Perhaps you see some of that in the above. I know i'm not the dullest tool arou

Good news, that did the trick, and as a benefit I understand a bit more about how this works. But realistically I'm a hardware guy and we really need a 3D printing software guy to work with in order to get the best results with this machine. There is an opportunity here if you want to help or know someone who might be a good fit.
So it's on to the show, Automate 2015 at the McCormick center in C

Thanks Dave, i have applied your recommendations and am running another test. Everything looks OK so far.
I guess we probably need much more RAM as it slows down greatly while exporting G-code. We have 4GB installed. I seem to remember seeing a much higher recommendation somewhere, but I also think I saw some reference to that being caused by improperly set parameters, which no doubt fits this s

Thanks Dave. I tried 1.3 with no greater success. Our printer bed is 900mm x 1200mm so that would be a little tight and is the reason I scaled the part to .7 which should have brought it down to 630 x 630mm and the image confirms this reduction. The preview at the 1.3mm size shows a 13m:25s print time,0 layer count, 644 lines.
OK, I downloaded and started Slic3r v1.2.6, changed the bed shape to

I'll confess to being a little lost. I'm using the version of Slic3r embedded in Repetier-Host v1.0.6 We are running a post-slice filter which is a Perl script to add line numbers, positional commands and layer numbers. I don't think it is particularly complex and we've been running it successfully.
In the configuration window under Print Settings / Advanced / Extrusion Width I had zeroed out al

Thanks Dave, I appreciate your advice.
The drawing does have width. Looking at an enlarged view we started with a square cross section but then increased the height to a factor of about 10:1 and I believe Tom told me he increased the width also. I also tried positioning the part partially below the plane of the bottom grid so that there would be no question of us trying to print the air between t

So why would the speed settings for Slic3r be in mm/s when the G-code outputted is mm/m? I realize there must be some way that this makes sense but I'm not following it.
Obviously our printer is scaled for GIGO so that we get out what we read in, but in in mm/s so what you are telling me is that we should create a scaling factor on our machine so that it divides the input by 60 and then the spee

We've run into another snag. We are trying to print the company logo in a single width line, mainly for a demo at the show next week and Slic3r isn't working in this drawing. It does output g-code after trying to download for a couple or three hours, but the file has no x or y coordinates. We widened the part thickness in an attempt to get it to work, and ran tha file through netfabb, which had w

Thanks guys, I'm sure we'll figure it out eventually. There's still some confusion about what exactly is going on here and I may not be the mosty qualified to sort it out but it looks like I've got the job anyway. So... what I do know is that the actual movement of the machine is in mm/s (about 10mm/s for building walls) and the G-code to run it is in mm/s. The G-code that comes out of Slic3r mat

Hi guys, let me first introduce myself by way of an apology for not really belonging on this forum. But I need your help.
We debut our new 3D metal printer at the Automate 2015 show in Chicago in about 11 days. (That's not what I'm asking for help with.) It is a large scale near-net-shape printer with a build envelope of 600mm H. x 900mm D. x 1200mm W. and uses a MIG gun for the extruder. The m

Thank you everyone for trying to help.
Yes, I know I could just put in the numbers in mm/s but we are not even close to being able to set and forget here. It's a new process and we'll have to play with the numbers for awhile yet.
I also know the G-code is in mm/m, and that is more readable. Although our rapid is up around 1000 mm/m our travel while depositing is more on the order of 2-20 mm/m. Mu

Hmmm.... well thanks for responding but I can't say I find that answer very satisfactory. Does Alessandro visit this forum often?

mm/M - 9 years ago
How do I set the speed units in the configuration editor to mm/minute rather than mm/s?
The printer we are sending the file to is calibrated in mm/M and the units look about right so we would prefer to change the units in Slic3r as the numbers will be more manageable.
Thanks,
Jim

Thanks for your help, that got us headed the right way. Steve has come up with a Perl script that he thinks will do the job for us.
We are grateful for your help.

Is there a simple way to save G-code to a file and keep the line numbers? When we saved to a text file the line numbers were gone. We want to send the file to another printer which uses a controller that expects line numbers with the G-code like a typical machine tool controller. The format we want uses line numbers like N0001, N0002, N0003, N0010, N0020 etc.
We tried a short file where we manua
