Hello all,
I just finished my first build, a Mendel90. I'm now in the electronics testing stage, and I've run into a couple of issues I hope someone can help me with. First, the motors. The X and Y motors do as they're supposed to in every direction including homing to their appropriate endstops. The Z motor, however, is another story. Initially, I went in the positive(i.e. Up) direction, starting with smaller increments and then moving to larger increments. Everything seemed good. I hit the "Home" button and it homed to the endstop located at the top of the printer. When I tried to move in the negative direction, though, the motor wouldn't respond. Turning the motors off, I backed the Z-axis down so that the endstop wasn't not activated, rechecked the endstop's response using M119, and confirmed that the endstop is responding how it should. Powering the motors back up, I tried again to move down the Z-axis, but nothing happened. I went up Z-axis a couple of increments without a problem. Curious, I hit 0.1+ (Z-axis moved up) followed by 0.1-(Z-axis moved down). Right, so I can get it to move down, but only after I've instructed it to move up. I did the same experiment with the 1mm and 10mm increments, each followed by the corresponding "down" command, and the motor responded each time. Still curious, I then hit 0.1+ followed by 10-, but the printer went down only 0.1. In other words, the down command, regardless of which increment you hit, mirrors the last positive command given. Ideas?
Second issue involves the heated bed. After testing the hot-end, which proved successful, I attempted to test the heating of the bed. Selecting 60C from the drop-down menu in Pronterface, I hit set, but I get an error message: [ERROR] Can't read from printer (disconnected?) (SerialException): call to ClearCommError failed; [ERROR] Can't write to printer (disconnected?) (SerialException): WriteFile failed ([Error 5] Access is denied.)
This repeats four times and the printer is disconnected. Disconnecting the mini-USB and reconnecting it allows me to reconnect the printer through Pronterface. I should note that the error message doesn't come immediately and, in fact, the bed begins to heat up in the 30 seconds or so before the first error message is delivered. Ideas?
Like many others here, I'm a noob so you may need to spell things out for me.
Still, I'm not completely brain dead. 
Thanks in advance!
