Just had a idea, will try it soon and see how it works out. What if you just wrap solder wire (without flux core) with the appropriate melting temperature with one or 2 turns around your extruder head. Insulating the wires from the extruder with Kapton before of course. Trough that solder wire you power your heating element. If now the extruder overheats the solder wire will melt and reliably cvon Gregor_R - Safety & Best Practices
Danke für eure Tipps. Werde mir jetzt doch das GRRF Hotend zulegen. Der ausschlaggebende Punkt ist, dass beim GRRF Hotend die Thermalbarriere aus PEEK und nicht aus PFTE ist. PFTE will ich ungern an den heißen Teilen vom Extruder haben, wegen der ziemlich giftigen Ausdünstungen wenn das Material überhitzt. Durch welchen Fehler sei jetzt einmal dahingestellt. Ich denke, darüber hab ich in dem Forvon Gregor_R - Extruder, Hotends & verschiedene Materialien
Hallo Ich möchte meinem Mendel ein neues Hotend spendieren. Dazu hab ich das Internet durchforstet und hab insgesamt drei ansprechende Hotends gefunden. Die Frage, die sich mir als "Laie" auf dem Gebiet der Hotends nun stellt (ist ja teilweise eine Wissenschaft für sich) ist, welches ich am Besten kaufen sollte. 1. GRRF Hotend: Hat einen, meiner Meinung nach, soliden Aufbau und auch die Optivon Gregor_R - Extruder, Hotends & verschiedene Materialien
Hi A 14 to 16V suppressor- Diode will do the job. You will simply have to connect it between the 12V rail and ground. The polartity is not important, you can put it in both ways. The power rating of the diode should be at least a few watts. If a voltage higher than the rated voltage of the suppressor diode occurs it will switch into low resistance mode and absorb the power of the spike.von Gregor_R - Controllers
Hi it's me again. I have a very stressful week behind me. So I had no time to update this thread. So here's is the update, and there are very good news. The teacup firmware is runnig perfect on the Gen3 Electronics. The problem with the temperature reading of the heated Bed, is actually a problem of ReplicatorG. The firmware passes extruder and heated bed temperature trough the serial interfacvon Gregor_R - Controllers
Hey I think I've found the problem. But I have no idea how to solve it yet. But it's late (1:48 here) and I should go to bed I am using a ATMEGA168 on my Extruderboard. I've studied the pinouts of the TQFP package version. ... and compared that with the extruder code. And i've found something that took me aback. Let's have a look at the following piece of code. #define AIO5_PIN PINC5 #definvon Gregor_R - Controllers
Ok I've downloaded and burned the teacup firmware with NoobMan's config files. I can connect with the machine and all the axis move correctly. Haven't adopted my configurations out of the reprap firmware to the teacup firmware, because this should only be a first test, to see if it works or not. (I've used other aluminium gearwheels on my reprap), so the steps/mm have to be adjusted in comparivon Gregor_R - Controllers
Thanks NoobMan for your detailed description. Maybe I'll give the Teacup firmware a chance.von Gregor_R - Controllers
@ Traumflug How should I ignore that? After the "FW accepted: ; resend ok" the reprap doesn't print anymore. It freezes forever. Until I switch it off and on again or press the Reset Button on the Motherboard. If I do so, the print is useless. A variable overflow might be a possible reason. Interestingly the error everytime occours on the beginning of a command. As you can see in the attaced svon Gregor_R - Controllers
Hi I'am Gregor, and coming from Austria. I have built a standard Reprap mendel and I am now in progress of finetuning the machine and troubleshooting some small but also big problems. I hope you can help me with such big problem, which frustrates me for over 3 days now, and is driving me crazy. My setup: * standard Mendel * with Gen3 Electronics * Firmware is orignal "reprap-mendel-2010080von Gregor_R - Controllers
