Hi, I came across this machine: [www.lightobject.com] It has 110 x 110 mm working area and 0.01 mm resolution. I am thinking about building SLS machine based on this. OpenSLS is based on a CO2 laser cutter. I think this fiber laser engraver would be better on many things; cooling, speed, footprint etc... https://reprap.org/forum/read.php?153,747177,747177#msg-747177 Sun, 19 Jul 2026 18:37:51 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?153,747177,780972#msg-780972 https://reprap.org/forum/read.php?153,747177,780972#msg-780972 I get it

Where they get powder still a mystery to me?

Did not get an answer for my request yet but maybe you can try ur luck.

with a standard scanner configuration the beam is in the middle - this can be done mechanically by turning the galvos in the mount.

The CorrCorrect.exe can generate this correction data file, which then will be loaded into BeamConstruct configuration - it's only meant to compensate distortion.

What you'll need to get correct dimensional values are the adjusting/scaling values for X and Y - to get them, you can scan a square with e.g. 50x50mm ... measure the result ... and if not correct, adjust the scaling factor for the axe ... repeat this, until you get the correct size ...]]> VDX Powder Printing and Selective Laser Sintering Thu, 27 Jul 2017 09:39:59 -0400 https://reprap.org/forum/read.php?153,747177,780338#msg-780338 https://reprap.org/forum/read.php?153,747177,780338#msg-780338 The only information which is needed by Beamconstruct or Corrcorrect regarding calibration are: the working area size and the distance of X- and Y-scanners from the powder bad? Then I can upload my CAD file and start to print?

Thank you in advance

what's your problem with BeamConstruct?

I'm setting the multiplicators in the scanner configuration to meet the dimensional abbreviation - actually it's 0,797 for X and 0,836 for Y.

The geometrical distortion can be adjusted with the programm CorrCorrect.exe in the OpenAPC folder ...]]> VDX Powder Printing and Selective Laser Sintering Thu, 27 Jul 2017 06:39:08 -0400 https://reprap.org/forum/read.php?153,747177,780325#msg-780325 https://reprap.org/forum/read.php?153,747177,780325#msg-780325
I got problems for calibrating the Galvo Scanners. I have a diode laser and 40 Kpps Galvo scanner with its drivers. As for the controller I have E1701A. I know that I cannot calibrate the Galvo Scanners using Beamconstrukt.
Could you tell me, how did you calibrate your laser Scanners? Do I have to get another software? Is it for free?
I read tutorials regarding ILDA test pattern but I do not have ILDA interface and the test pattern file.

Could you help me? Is there any other way besides of ILDA test pattern?

I am using this Diode Laser.

I realise that I have to switch to the E1701A controller, because my Galvo Scanner inputs are analog. Digital controller was not a good idea. I am waiting for the new controller to start to work again. :)]]> Sara.Ami Powder Printing and Selective Laser Sintering Thu, 20 Jul 2017 03:46:39 -0400 https://reprap.org/forum/read.php?153,747177,779076#msg-779076 https://reprap.org/forum/read.php?153,747177,779076#msg-779076 www.vestosint.de]

the GND's are internally connected, so you can use any of them.

My laser needs two driving connections from "LaserA" and "Gate" (both with GND) to control the Power and MO -- but this depends on your laser type, so can vary ...]]> VDX Powder Printing and Selective Laser Sintering Wed, 19 Jul 2017 15:10:59 -0400 https://reprap.org/forum/read.php?153,747177,778908#msg-778908 https://reprap.org/forum/read.php?153,747177,778908#msg-778908
I am trying to make a SLS printer using E1701D controller and Beamconstruct. But the topic is new for me and I do not have enough knowledge.

I see that you have experience with this board. I have just started and I do not know how to connect my laser to the controller even that I have the manual.
My laser driver has two controlling pins. One of them will be connected to LaserA pin of the controller. Should I connect the other one to the Pin 12 as GND.Or not?
I know it`s a very simple question but since the laser control signal of Controller have two GND pins (12,14), I am confused.

Thank you very much in advanced.
