I think I may have been caught with too small a motors for torque and inertia. I am building with 8mm linear bearings so they may be o'k. Seeing most of the set-ups I think 1.4 - 2 amp motors are requitred with NEMA17 frames about 40mm long. I understand the driver boards are build for 2.5 amp max.by Scrachbuilder - Reprappers
Initially I have only the motors laid out on the table to check out the Ponterface software, and I keep getting extruder error message, even when set to zero. I was thinking the extruder had to be attached but now I see that I may need to check sli3er. I think someone might needs to document all the error messages - for likely causes.by Scrachbuilder - Reprappers
