Hey Guys, Looking for some help / hints as to improvements to my Bowden extruder. I recently converted my Gregs-Wade accessible extruder on my Prusa Mendal to a bowden extruder. I used 2mm ID Teflon tube from Seemecnc, and I made my own attachments for the tube using a 4mm nut and washer to secure it to the extruder motor and hotend. (see Attached) The problem I have been having is that, whenby drewsipher - Mechanics
I'm pretty sure you can set what command line pronterface executes, in pronterface's settings.

Thanks egenoup, I figured that was the case and always disconnected, unpowered, and de-static-ed (is that a word) the board before changing the stepper drivers. However, having them seated backwards on the first attempt to power up the board may have damaged one or two of them. Lesson learned.by drewsipher - Sanguino(lolu)
Just an Update: Last night I managed to borrow a friends Stepsticks (duplicates of what I am already using) and some new Pololu A4988 stepper drivers. And that seemed to do it. The Pololu A4988's worked pretty well. I managed to get all 4 axis working with 3 polulu's and one stepstick I found one axis that was working for sure (to make sure it wasn't the chip or the board or the firmware), anby drewsipher - Sanguino(lolu)
Hey Guys, I'm new to the forum and repraps, and wondering if anyone can help me to fix/diagnose what is going on. I have built a Prusa Mendel with a Sanguinololu 1.3a board, atMega644P Chip running Sprinter , and when I connect to the board with Pronterface or ReplicatorG I can get some of the axis to move. Mostly, The Z-axis works. I have had success with the E-axis and just recently the X-axiby drewsipher - Sanguino(lolu)
