So sieht die erste Schicht bei paar Drucken aus (oder das, was es darstellen soll). Manchmal hat es kurz Haftung, doch dann löst es sich wieder ab. Ich war auch heute bei Conrad und habe dort 3M Scotchtape (das Blaue) gekauft und es grad probiert, das Resultat ist das gleiche.by DocRaptor - Allgemeines
Zur Frage was ich drucke: PLA, genauer gesagt dasfilament translusent green. Gelevelvt habe ich das Bruckbett auch schon. Das prüfe ich auch mit der Zeit mal, ob sich da was geändert hat. Ich habe auch schon paar andere Spiegel aus dem Packet genommen (12 Stück kosten ja nur 7,90) und gereinigt habe ich die schon mit mehreren Reinigungsmittel (Spülmittel, Fensterreiniger, Aceton und einen Industrby DocRaptor - Allgemeines
Hi, ich habe ein Problem bei mir und zwar will der Druck nicht mehr haften. Ich drucke auf Glass bestrichen mit Pritt Stift (Original) und hatte (bis auf paar mal) nie Probleme mit der Haftung des Druckes. Nur auf einmal will der Druck nicht mehr haften. Ich habe nur Glass versucht, Glass mit Pritt Stift, Glass mit Harspray, Glass mit Harspray und Pritt Stift, Glass angeraut mit Dremel (soweit maby DocRaptor - Allgemeines

Here is the next update of the files of version 2 of the printer: - Excluded the parts of the printer, which are the same on every bushingsize, and put them in to the file universal. - Pulleymounts corrected. - Upper z-axis mount corrected. - Added lower z-axis mount with Nema 17 stepper motor mount for this axis.by DocRaptor - CoreXY Machines
Here is an update of the files of version 2 of the printer: - Added files for 13mm bushings. - Part of the z axis assembly using a M8 lead screw with 608 ball bearing instead of M6 without any ball bearings (5mm to 8mm shaft couplings are more common than 5mm to 6mm shaft couplings and 608 ball bearing are also used in skateboards)by DocRaptor - CoreXY Machines
After some calibration I got it working. The prints, well let us say they aren't the best, but I can work with them. I started to print some mounts for 8mm aluminum tube profiles. These parts will mount to the axis mounts to reinforce the printer. I upload this part. Also I upload some of the files of new parts for version 2 of the printer. This includes: Axis mounts with integrated 8mm tube profby DocRaptor - CoreXY Machines

I made my first testprint (and abort it). There a few problems, but these things I hope can be fixed with adjust the software and some other things. The Extruder push to much and is rubing on the fillament and there is no fan in the moment, I have to mount one. I but I hope to solve them.by DocRaptor - CoreXY Machines

I know there are some designflaws, but at least its not a complet desaster like my previous designs I talked about. I use the Nema 23 motors now because I had them liyng around for years and the next design I work on will have Nema 17 motors.

Hi everyone, I currently design and building my own 3d printer from scratch. The first fews tries failed with the x and y axes. I tried the ultimaker-style, but leveling linear guides was nearly imposible (and first I tried it with leadscrew ). So I try now the h-bot design, but I wait for a few printed parts to be printed (I don't have my own printer, so this is my first 3d printer). But I thougby DocRaptor - CoreXY Machines
