Thursday, January 1, 2009

I cut out the parts for my Z-axis assembly using a jigsaw, and while butting the machine edges worked fine the other edges were a bit sloppy. I took advantage of an in-law’s shop to finish them up with a table saw and now the edges are much nicer. The base dimensions of my Z-axis [...]

CNC – First 2.5D cutting

Saturday, November 29, 2008

Because I’m still using python code I wrote myself and have not yet calibrated my stepper coordinates into real-world measurements, I had to design the bracket in Inkscape, print it out, and manually move my router [...]

Checking Accuracy
Using my simple router code I had the X/Y table plot a square with a circle inside of it (and then added some extra code to draw a smaller circle inside that). The first time I tried this I found that one side of my X/Y table was significantly (1mm or more) lower than [...]

(Cost: 65 AUD) Although it supports up to a 6kHz stepping rate, I found that my steppers can only be driven at the RATE 12 setting, or approximately 745 steps a second. I’m not sure if this is because I’m [...]
