Printer connects fine, but commands do not send. Status reads xx commands waiting. Is there something else I should be trying, or what is the correct baud rate to set? BCMA0 Bluetooth 4. Maybe try usb-devicesI think it gives you the speed. I'm most interested in the output of usb-devices.

Maybe usbview? I guess that you've double checked that this the board, by disconnecting the printer, running the commands, and then connecting the printer and runningthe commands again, to compare the difference. Also, it seems that the speed isn't given after all I was hoping that Spd was speed, but yours shows Active topics Unanswered topics. You must login or register to post a reply.

How to connect a 3D printer to Cura

Open printer settings? I confirmed the bit's per second matched up Repeiter was set to so I matched the device manager to that, but I also tried several others. I reverted back to Repeiter Host V1. I just did the same and it didn't connect at first either. It seemed to take a minute to connect then it worked out. Leave it sitting and then come back in a minute and try to reconnect. I kept trying and it just started working again. I'm still using 1. I always get this issue when I turn my printer off without disconnecting from RH or when I restart my computer with the printer off and then turn it on.

When I turn the printer on before starting the computer or restart with the printer on, RH picks it up. I just chalked it up to the program being picky. I'll report back if it does. Solidoodle techs nor my 2 IT Sons could figure this out, but I kept trying things til I learned the problem and how to fix it. I never have the issue anymore and still got the old problematic SD board knock on wood build base hehe.

Slic3r also have all free ware STL programs.I bet loads of people have struggled to connect their 3D printer to a personal computer!

There is a way to ensure you are selecting the right port in a matter of seconds! Connect your printer to your pc correctly with a USB cable. This number is the port that you need to use.

There are some cases when a damaged cable can lead to a bad connection between the two devices. So perhaps you are asking why should I control my 3d printer from a PC?

There are lots of good reasons to do so. The main benefit of doing so is that you can manually send G codes to your printer, this is fundamental for testing and calibrating different values. Setting your e-steps needs you to manually input the distance extruded so you can check the difference between the demanded length and the actual length extruder by the printer.

I will be speaking about e -steps in another article. When your printer goes in printing mode it executes a starting script, there are some occasions when we want to alter this script. Well, we can do this without connecting our computer but it is preferred that you test the script before you launch it.

It is much easier to just slice right away and click print, than saving the Gcode file on a memory card and start your preparation process. I love using my printer from the computer, I prepare everything on the spot with Cura. I preheat the printer while I prepare my printing settings, home all the axis, and auto-level. Once done all these steps I slice my model and click print. You can control remotely your printer with Cura if you want.

To achieve these you must set up a server and install software on it that can manage your printer. Usually, you use it to upload files and send the print command to your printer.

The easiest software to use in this case is Repetier-Server. After that you only need to add your printer to Cura with the network options, setting up the IP manually. This is kinda useless on Cura, usually, for this kind of task, I use a Repetier host that integrates Repetier server and makes the process much faster and easier.

So how do you avoid those problems I talked about earlier without too much of a headache? The easiest way is by using the latest version of Cura. And I will explain to you why. Cura searches all ports and tries all baud rates so eventually, it will find your printer!

We will need to adjust the printer settings, exactly the X, Z, Y lengths. After that go to extruder settings and check that you have the right material diameter set. After we finish with the printer settings we only need to connect it to our computer with the USB cable and start the printer. Go the monitor tab on Cura when you see the connected icon.

The control panel seems easy and nothing too complicated but there are some first things to do : Home all axes. Looking in the photos you are going to see the XYZ controls, this is used to move the axis around, in the center of the commands you can find the homing button displayed as a friendly home icon.Repetier-Host Windows 2.
