    Hello all,
    Can anyone tell me what I should be looking for when I get the following issue?

    I typed in G1 Y50 F500 and this is what the log shows below. I cut and pasted so Repetier added an N37 *19 and the result was the communication timeout.

    14:28:40.075 : N37 G1 Y50 F500 *19
    14:29:14.834 : Communication timeout – reset send buffer block

    I tested the Arduino earlier with the REPRAP Ramps 1.4 pre-flight check script and all the motors turned just fine.



    can you manually move the motors in repetier? second time I have head of this we need to figure this out.



    I don’t have my cnc unpacked yet , butMy repetier says the buad rate is 250,000 does that match yours? Someone else was having repetier issues and said that pronterface works just fine. Might want to give that a shot. I have not tried it though.

    I would really like to know why these issues are popping up.
