Introduction: Reuse Old Fax As a Plotter
You need take apart old fax machine, I don't have any photo of it before tear-down.
mine have 2 stepper motors
1 that move printer head, other move paper.
Step 1: Z Azis
my Z axis is a floppy drive that I cut in half and hot glue it on carriage.
Step 2: Assembly Hardware Part
Video is on Russian, I will add annotation to it soon.
1 arduino UNO
3 modules for stepper motors L298N
1 power supply 7.5v 1A
Step 3: Wiring
each motor module have 4 signals, Vin and 4 connectors for bi-polar stepper motor.
so arduino pins 2,3,4,5 goes to 1 steper
modue 6,7,8,9 second
and 10,11,12,13 -> third it must be Z motor
Step 4: Now the Fun Part, (software)
Software I copy pasted from this article
More information about the Mini CNC Plotter here (german, sorry):

My modification is on github

I hope you like my tutorial, if you have any questions don't hesitate to ask!

hellow, i already made one by two stepper motor and one servo, but its working area is only 4cm by 4cm it cant print beyond that although i have enough drawing area. How can i increase it by 200mm by 200mm? I changed the code Xmax= 40mm to 200mm, but no improvement. Will u please help me with this will be very grate full. thank you

Yes Xmax should do the business,
or you can remove Xmax check, just delete those lines
if (x1 >= Xmax) {
x1 = Xmax;
}
same for Ymax

yea it should work, but i got problem with inkscape it cant produce g-code out of 4cm by 4cm. if it does, but plotter cant print rest. I have downloaded inkscape new version from its websites, but no change. I saw some tutorial from youtube where they have some new extension which i dont. How can i have this? Do you have inkscape that can generate g-code of 20mm by 20mm without any error? If u have will u please give me i need it urgently and i will be very great full to u.
