Hi I'm having some problem with my 3d printer

Question

Hi I've just bought a cheap Chinese 3d printer.

When I connect printer to my computer it comes to life (all lights are blinking and motors move on spot a bit) but when I try to print cura says detecting baud rate and nothing happens. I'm using windows 10 if that matters; also tried with my mac didn't help. It is a ctc dual-extruder 3d printer.

I've read that should make change something about Marlin but I don't know anything about it.

Specs on 3d printer if you need:

Electronics

· CTC Board single-piece motherboard

· 5 axis, 1/16 micro-stepping motor control

· 4x20 LCD character display and multi-direction control pad

· Universal Power Supply: 100-240V, 50/60Hz

Software: ReplicatorG

· Compatibility: Windows.

· Print from SD card or over USB

· Input file type: STL, gcode,x3g

Can you give more details about the "motherboard"?

What markings are on the main microprocessor?

If you are unsure, post a photo of it.

If it uses an atmel chip, chances are good its arduino compatible... which opens up quite a few options.

If you are looking to build your own, or re-work an existing 3d printer, I highly recommend software called repetier host.

These guys write both the firmware and software.

For the firmware, you configure the options specific to your printer on their website (size, position of limit switches, etc) and it creates an arduino sketch that you can load onto an arduino mega.

Then you download their corresponding application for your pc or mac that handles all the slicing, and fires the g-code off down the usb cable to the arduino. They use the popular slicing engines like cura, slic3r, and skeinforge... you can choose which one you want to use.

"Marlin" is the firmware used by some 3D printers. Typically, this is flashed on an Arduino compatible chip on the printer's control board. Could you be more detailed about: I've read that should make change something about Marlin

Also good to know where the printer was bought and what is the original brand. Most of the cheap Chinese sellers are resellers as gearbest. Enrico

What is your baud rate setting? Is it 115200?

mmcphail · Answer

i second the above post about baud rate, i have a cheap CTC printer myself that refused to work until i changed the bad rate to 115200

Robert Peter Oakes · Answer

If you look at a lot of the examples for driving 3D printers and other motion control solutions with an Arduino (ATMEL) controller, there almost always hard coded to 115200 baud or even higher. If in doubt then check the source code configuration files that is nearly always available.
