I am a giant!

     Because as you know your height is the same as the distance from  fingertip to fingertip.   And the distance between my fingertips is over nine miles.

     And that means you have to be careful when using butcher knives.

     So before using any kind of cutting tool think of the worst case scenario and don't have your fingers there.

Troubleshooting 3-d Printer

This blog is a place to collect notes to be worked up into a Tips post for trubleshooting 3-d Printer problyms.

The idea is to list a symptom with a photograph and list sucsful fix actions to try.

 


 

For Example:

Printer: Printerbot LC

Material: ABS

Notes: Extruder temp 230C, Bed temp 110C, Fan on 100%,Polymide (Kapton) on a glass bed 

Problym: Poorly formed vertical edges, Keystoning (wider at the top then the bottom)

AXE023 The Secret Data

I am calling this THE SECRET DATA because i could find no explanation of the four terminals on the bottom of the board.  I did find a forum where someone asked but the picaxe support person didn't answer that part of the question.

They are connected to ground.

     Another thing worth knowing is that it as not compatible with the motor command in Logicator.(the flowchart programing gui)

  Knives Forks and Spoons is my homage to Chopsticks and Chopsticks Jr.. (I hope to end up like Chopsticks Jr. - Beaten to death by a Model during a photo … Read more
