Doenst even know the problem Hi i have bought me a geeetech pro b. At first i wanted to change my z threaded rods and realized i cant change anything in arduino on the gt2560. So i got me an mks sbase 1.3 but then i had extrusion problems. I could only print at 250C and even then the bowden extruder cant handle the force requiered. Next i installed a new arduino ramps 1.4. With the same behaviour. (I choose on both boards the right Thermistor) I also changed the power supply. 62amps B) The heatsink fan is runing on 12 v My Setup: Geeetech Pro B Arduino Ramps 1.4 Marlin Bernis simple bowden extruder E3D V6 https://reprap.org/forum/read.php?262,759649,759649#msg-759649 Sun, 15 Mar 2026 06:52:38 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,759649,760530#msg-760530 Re: Doenst even know the problem https://reprap.org/forum/read.php?262,759649,760530#msg-760530 nottub Printing Wed, 05 Apr 2017 04:31:13 -0400 https://reprap.org/forum/read.php?262,759649,760460#msg-760460 Re: Doenst even know the problem https://reprap.org/forum/read.php?262,759649,760460#msg-760460 ggherbaz Printing Tue, 04 Apr 2017 11:30:33 -0400 https://reprap.org/forum/read.php?262,759649,760418#msg-760418 Re: Doenst even know the problem https://reprap.org/forum/read.php?262,759649,760418#msg-760418
But my controller doesnt get powered from the main 12v. Also if i connect 5v to the arduino it doenst even light up. But it works when i connect the usb cable to the arduino.
Any ideas]]> nottub Printing Tue, 04 Apr 2017 07:51:36 -0400 https://reprap.org/forum/read.php?262,759649,760025#msg-760025 Re: Doenst even know the problem https://reprap.org/forum/read.php?262,759649,760025#msg-760025 nottub Printing Sun, 02 Apr 2017 05:20:27 -0400 https://reprap.org/forum/read.php?262,759649,759651#msg-759651 Re: Doenst even know the problem https://reprap.org/forum/read.php?262,759649,759651#msg-759651 obewan Printing Fri, 31 Mar 2017 07:56:22 -0400 https://reprap.org/forum/read.php?262,759649,759649#msg-759649 Doenst even know the problem https://reprap.org/forum/read.php?262,759649,759649#msg-759649 So i got me an mks sbase 1.3 but then i had extrusion problems.
