Hi, I installed a thermocouple in my prusa with a megatronics v. 1.0. To avoid flickering I put a 10nK100 capacitor on the thermocouple. Now the problem: when the extruder is cold the thermocouple gives 6.8 degrees but the room is at 19 degrees. Does the thermocouple is working?by bissaorboea01 - Controllers
Hi nophead, I swaped X & Y motor connection and the rectangle have the same shape. So it was is a mechanical problem: I was using T2.5 pulley on 5cm belt. Thanks Nophead!by bissaorboea01 - Firmware - mainstream and related support
Hi, I'am a new to reprap and I have a problem that I hope sameone can solve. I'm using a Marling on e prusa using Megatronics Board. I set the Steps per mm in the following way: #define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, 200*16/1.25, 760*1.1} // default steps per unit for Prusa When I print a square the X axis is correct but Y axis is longer by 10%. The belt are tightened, I use theby bissaorboea01 - Firmware - mainstream and related support
HI, I had the same problem, yesterday. I solved putting the correct step per mm in configuration.h in the firmware: //#define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,200*8/3,760*1.1} // default steps per unit for ultimaker #define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, 200*16/1.25, 760*1.1} // default steps per unit for Prusa @BIssa The definition is for the X,Y,Z,E axis, so theby bissaorboea01 - General
