I'm having some issues getting my code to compile for enabling dual extruders. It seems to be the same issue anwofis and k3vbot3000 had here and here. My code compiles just fine until I change #define EXTRUDERS = 1 to 2. When I do change it to 2 extruders, this is the error I am getting in the Arduino IDE. I tried the solutions listed in each of their threads, but to no avail. Arduino: 1.6.2by eovnu87435ds - RAMPS Electronics
Thanks for the reply! I'm looking for some more cooling power for my hotend, since with the extruder I have (Folger Tech), I can only print ABS for about 2.5 hours before it clogs from overheating. I had a remedy where I had my parts pause every 10-15mm in height, cool the extruder, then reheat it and continue, but it was quite a hassle. I tried that fan out, turns out it was a bit too good forby eovnu87435ds - General
I am putting a bigger fan on my Prusa i3, and I wanted to know if there was an official spec for maximum fan amperage. I know that the rail that supplies the fan power has to be a minimum of 5 amps, but I wanted to make sure that I won't be destroying anything with running a fan that can pull a max of 1.2A. Any help would be much appreciated! -Mikeby eovnu87435ds - General
Following your advice, I put some insulation under the bed, switched to the server PSU and cranked the voltage up to 14v or so (no load), and put an old halogen lamp approximately 40 cm above the bed, for lighting and keeping the ambient temps warm. Works like a charm! thanks for your help!by eovnu87435ds - Printing
thanks for the quick reply! 1. Using the supplied PSU, the voltage during heatup is 12.14v at the bed, 12.15v at the RAMPS power connector. For the Server PSU, it's 12.91v / 12.92v. 2. With the Server PSU I am reaching 96 degrees. This is with the thermistor taped directly to the PCB(underside) of the bed about 2mm from the center hole.by eovnu87435ds - Printing
Hi everybody, I just set up my prusa i3 kit from Folger Tech, which comes with the RepRap MK2B heated bed. With my initial testing, I found that I couldn't get the board hotter than 90 degrees or so. In trying to fix this, I went through the relavant wiki pages, quite a few forum posts here, and tried many steps of my own before posting. Here's my findings. I'm, running marlin 1.0.2, cloned fromby eovnu87435ds - Printing
