Introduction: Reuse Old Fax As a Plotter

Picture of 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

Picture of Z Azis

my Z axis is a floppy drive that I cut in half and hot glue it on carriage.

Step 2: ‚ÄčAssembly 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

Picture of 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

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.
