Not a lot to tell, but much going on.

Having my own business means having a more professional electronics lab is a must.
So I’m moving from the attic to our outside workshop. That also means I have to make our Music Studio smaller.

So moving, printing a lot on my new 3D printer and designing EuroCards.

Above card will hold two address decodes parts, selectable using jumpers. ( Old skool TTL using 74xx and a new solution using ATF22V10.

We like Low Poly models, so I printed one using marble PLA.

I’ve cleaned my old 3D printer, and I am planning to convert this printer to a 2D plotter and a CNC machine.

I’ve already printed a pen holder and a dremel holder.
(The filament head will be removed)

I’m working on a Gcode writer to plot drawings using a pen, or using a Gyro-cut knife to cut paper.
And the biggest project using this old 3D printer, a CNC machine!

Test Code:

import time
import serial

arduino = serial.Serial('/dev/ttyUSB0', 115200, timeout=.1)

# Motor stuff
arduino.write(str.encode("M84 X Y Z S12000\r\n"))
arduino.write(str.encode("M92 X160 Y160 Z800\r\n"))
# Extrude fix
arduino.write(str.encode("G92 E0\r\n"))
# Go home
arduino.write(str.encode("G28\r\n"))
# Move to x,y,z
arduino.write(str.encode("G1 Z90 X50 Y50\r\n"))
# Wait
arduino.write(str.encode("M400\r\n"))

Sin wave fun:

import time
import serial
import math
from time import sleep

arduino = serial.Serial('/dev/ttyUSB0', 115200, timeout=.1)

arduino.write(str.encode("M84 X Y Z S12000\r\n")) 
arduino.write(str.encode("M92 X160 Y160 Z800\r\n")) 
arduino.write(str.encode("G92 E0\r\n")) 
arduino.write(str.encode("G28\r\n")) 
arduino.write(str.encode("M220 S100\r\n")) 
arduino.write(str.encode("G1 Z10 X60 Y60\r\n"))
arduino.write(str.encode("M400\r\n"))
sleep(10)
count = 0
while True:
	newx=(math.sin(math.radians(count))*50)+60
	newy=(math.cos(math.radians(count))*50)+60
	newz=(math.cos(math.radians(count))*10)+20
	count = count + 1
	mystring="G1 Z" + str(newz) + " X" + str(newx) + " Y" + str(newy) + "\r\n" 
	print(mystring) 
	arduino.write(str.encode(mystring)) 
	arduino.write(str.encode("M400\r\n")) 
        # Not waiting for answer yet
	print(newx) 
	sleep(0.1)
