Re: Thingiverse perhaps not great - 10 months ago

Hi Mike, ... some more info for the cause? -- if for security reason, then some of the other formats are even more "vulnerable"

Re: Laserdioden werden immer stärker - wofür verwenden? - 10 months ago

Hi Patrick, ... wenn du T1 abklemmst, sollte zwischen den beiden Widerständen R14 (1k) und R6 (3.3k) genug Spannung anstehen, um den MOSFET durchzusteuern, damit der Strom durch die Diode und durch den MOSFET gegen Masse abfließen kann -- wenn das nicht geht, miß mal die Spannung zwischen den beiden Widerständen gegen Masse - das sollte >7V sein. Der Transistor T2 "invertiert" eigentlich nur

Re: DELAMINATION ISSUE - 10 months ago

... delamination is mostly caused by low temp, so the layers won't melt together -- so rise temperature higher, than with your previous tests ...

Re: RepRap used for farming - 10 months ago

... think about the "verticsal farming" idea too! -- then you don't need big fields and the "robots" could too be much simpler/smaller

Re: Converting to 24V - 10 months ago

... this "erratic stops" could be due to overheating -- try with better cooling and slightly lower current.

Re: Erster Eigenbau - 10 months ago

... ich habe auch noch von einer der letzten Messen auf denen ich vor Corona war, 6 von den Igus-Steilspindel-Demo-Sets und zwei von den "Igus-dry-tech"-Demonstrations-Koffern und noch einiges an deren Linear-gliding-Mustern sowie Reib-/Gleit- und Kugellagern da, was ich für kleinere Prototypen-Aufbauten verwende. Mit Vorspannung funktioniert das eine Zeitlang ganz gut, dann muß aber entweder wa

Re: Homing issues - 10 months ago

... with many firmwares you can set the "homing position" to any value, you want ... so check, if you have set it somewhere to max.

Re: Laser Hot End - 11 months ago

... yes, we (mostly me) were thinking about such "minimal-heaters" some 10+ years ago - then I had only IR-Laserdiodes with [email protected] out of a 0,1mm fiber ... but, beside some functional tests no big development then ... but was done some years later for fluid-jetting. Now I have IR-Laserdiodes with up to [email protected] on a spot of 0,2mm diameter and actually reactivating some of my old stuff for

Re: How to I send G-Code File through serial? - 11 months ago

... best bet could be to wait, if others will come by -- my colleagues are either in different themes ... or maybe even more busy than me for actual reasons

Re: How to I send G-Code File through serial? - 11 months ago

... I've modified some parts of Marlin4Due for my needs and to "expand" the communication to/from Pronterface ... and added some new M-codes too. But this was "2 dayjobs back", so actually no time or interest to dive into again

Re: How to I send G-Code File through serial? - 11 months ago

... if the capability of common G-codes (and M-codes) arent sufficient, then you have to write your own firmware. By the way - I'm controlling big industrial ultrasonic cleaners with up to 5 vats (+ load and remove zones) and moving ranges with up to 4 meters horizontal and 500mm vertical with a "standard" Marlin4Due (same as Marlin, but config/setup for ArduinoDue) ...

Re: How to I send G-Code File through serial? - 11 months ago

... I'm mostly using teraterm for sending multiline-macros or files per serial ... or, if reading/reacting to handshake too, write my own "senders" with VisualBasic or Python ...

Re: Brauche bitte Hilfe Creality Ender 3 v2 - 11 months ago

... versuch mal mit verdünntem Holzleim (ich nehme da ab und an mal Pritt-Stifte) als "Haftvermittler" -- dünn auftragen/drüberstreichen, andtrocknen lassen, drucken ... Die Haftung ist oft auch abhänging von der Dicke der 1. Schicht -- einige Kunststoffe muß mal richtib "aufbügeln" ... bei anderen (und "Haftvermittler") reicht es einfach nur etwas wärmer "aufzulegen" schon aus ...

Re: How to manually execute G-Code commands - 11 months ago

... I'm using Masrlin4Due (same as Marlin, but for ArduinoDue) as firmware for ultrasonic cleaning systems for moving the basket from/to different positions, switching the US-senders and pneumatic actors or reacting to sensors by sending the G-codes directly to the ArdinoDue with "plane" RS232 in a VisualBasic environment. It's as simple as invoking a serial port, setting port-number and baudrat

Re: FDM 3D printer with UV Resin? - 11 months ago

... the smallest droplet size depends on viscosity and "content" of the paste - the blue glue was around 0,07mm smallest, other pastes could be like 0,04mm. The curing time depends on droplet size too, activators/inhibiters and additives - some 10 milliseconds per droplet, but I'm either dispensing/curing continuous with the nozzle-design, or (with the piezo-jetter) printing the complete slice,

Re: I burned Arduino on ramps 1.6 - Dunno why... - 11 months ago
