If you need a strong part, I recommend XT, for normal purpose, like decoration, there is no need to print with XT. About surface finish, to my opinion it's the same, of course it always depends on the settings you print with.

Al een andere USB kabel geprobeerd? De firmware varianten staan in de volgende directory's: Windows 64 bits: C:\Program Files (x86)\Cura_XXXX\resources\firmware Windows 32 bits C:\Program Files\Cura_1XXXX\resources\firmware Gezien je een UMO hebt met een originele HB kit dien je de hex file "MarlinUltimaker-HBK-250000.hex" tte gebruiken.

Hallo Meskers, Wat ik normaliter doe voor het uploaden van firmware (vanwege dat er regelmatig een time-out optreed): USB kabel in de UM steken, maar nog niet in de laptop/pc; Cura opstarten, de juiste HEX file selecteren (Machine > Install custom firmware) totdat Cura aangeeft dat er geen connectie is; USB kabel in de laptop/pc steken en de firmware wordt geupload.

Do I hear another fabulous design coming up from you Robert?

If I look closely at the picture it looks that the temp of 245 is too high. All those blobs and (almost) drooping filament at the corners of the object. My suggestion is to print at 240C on a UM2, with a fan speed of 50% and a layer height of 0.12 or 0.15mm.

I'm melting over here......

Nou, eigenlijk niks, heb aardig wat in VB geprogrammeerd, ik ga m'n zakelijke agenda morgens eens bij pakken.....

Thanx Arjan. Yes, the optimum temp is around 250 degrees, of course this depends on the measurement of the thermistor. Print speed was 50mm/s for all the cylinders. I'm going to make the construction below to be able to make more precise measurements for layer adhesion: If anyone has comments on that to improve the design I'm all ears !

Dank je Arjan, is wel erg verleidelijk zo'n cursus..........

Lijkt mij ook ja.....

Wel het proberen waard lijkt mij, bedankt voor de tip Arjan !

Heb je PM ontvangen en je een e-mail gestuurd......

Heb je een PM gestuurd....

Zul je geen spijt van krijgen........

Hallo Blizz, Heb voor een collega 1,5 jaar geleden een telefoonhouder voor in de auto geprint in PLA, de 1e beste warme dag vervormde deze. Vervolgens in XT geprint, houder zit nog steeds in de auto. Voor in de winter zal je PLA print het wel houden.

Good news, have a go to publish some results, here they are: I've done beta testing for ColorFabb XT colors and have access to a bench press, could not resist to make some pressure tests with it. One of the tests was a 45 degrees structure like the image below: The walls are 2mm thick and printed with a layer height of .2mm and all perimeters, no infill. Purely out of curiosity I wanted to know what kind of weight this structure could handle. The bench press keeps pressing until is detects that there is no resistance anymore. In the video below you'll see how that looks: The result was a pressure resistance of 0,570 kN (kiloNewton) = 58 kilograms. Knowing that I've made a cylinder with a diameter of 75mm, 1.2mm wall's and no infill. Printed 5 of them in XT black with different temperatures starting at 220 degrees up to 260 degrees. Main goal was to see what temperature gives the best layer adhesion, horizontal and vertical. As expected, cylinder 1 and 2 couldn't handle much pressure, the adhesion of the walls was not good and during the test a crack sound was audible what was caused from poor layer adhesion. Cylinder 3 exploded during the test, at that point no video was made anymore of the black cylinders during safety reasons. The video of that exploding cylinder can bee seen here: I printed another cilinder in XT transparent, made a safe shield for the camera and myself, and filmed that test also: Gathering all the tests together in one graph: Calculating newtons to kilograms: You are reading it right, ColorFabb XT can hold more than 825 kilograms with a wall thickness of 1.2mm ! Imagine what that would be with a wall thickness of 2 or 3 mm....... The remains of the test on the bench press: All cylinders collected together:

Stop teasing us !!!! :grin: :grin: :grin:

Because I made those tests for a company as a beta tester, I've asked it already, waiting for an answer.

Domme opmerkingen bestaan niet Patrick :-) Rechtermuisknop op de hex file, opslaan als of link opslaan als selecteren, en opslaan als een hex file. De code kopiëren en inderdaad als een hex file opslaan kan uiteraard ook.

My favorite too! I've made a crush test on a professional pressure bank to know how much weight a standard printed cylinder can hold, it was a surprising outcome! I'm not sure if I'm allowed to share the vid and results, I'm willing to ask if anyone is interested, cannot promise anything although....

Indeed, wow !

Hallo Patrick, Net even gekeken op marlinbuilder.robotfuzz.com, kan de zip file inderdaad niet downloaden, maar wel de hex file. Als je die upload naar de Arduino (via Cura > Custom Firmware) zou het normaliter moeten werken. 2 weken geleden op dezelfde manier mijn eigen gebouwde printer zo van de firmware voorzien.

Don't apologize Zoev89, your son is more important than anything else........

Unfortunately I'm not coming neater, still have a lot of testing to do and I'm already behind schedule :unsure: ......
