Hello,

I’m relatively new to 3d printing. I bought a hictop A602 prusa i3 a while back and it was functioning pretty well but I always struggled with leveling the bed. So I decided to add auto bed leveling to the printer. Come to my surprise that the “ramps” board did not have the pin out for the BL touch I had bought. So I bought a arduino mega 2560 with a ramps 1. 4 board and decided to upgrade that as well.

My issue is that I’m trying to upload the firmware and the arduino ID shows successful but I am not able to get anything IE pronterface or octoprint to connect. I have double checked that the mega 2560 is functioning by doing the blink test through the arduino software. I am also able to load the ramps 1.4 test to the board and that runs just fine. Can anyone point me in the right direction to solve this?

Thanks in advance

Check device manager for the com port. You might need to install drivers.

Thanks for the input but the board shows up in device manager under com 4.I’m also able to load tesf files and firmware successfully but after the firmware is loaded im not able to connect via pronterface or octoprint to test it.

Try connecting it to a different physical USB port.

Also get charge the USB cable.
I had some problems with my actual port in the past.

If that does not work, check that you’ve configure the correct baud rate in Marlin, and also using the same rate b in your host software.

Check your connect speed. I had a clone that would not connect at max speed.

thanks for all the ideas.I tried all the usb ports on both my laptops with all available baud rates with no success. I am still able to upload files successfully but after that I am not able to communicate with it via a print host. I have also tried a few older versions of marlin with the same results

Check the connect speed in the firmware. You may need to drop it one level.

8

Check connection speeds. My Hictop wouldn’t work at max speeds but 115000 setting works perfect

Ditto.

thanks for all the ideas but no such luck. I tried all available baud rates allowed by my laptop with no luck. I even u installed and reinstalled the arduino drivers.

11

Did you actually change it in the firmware of the printer?

12

Yup I changed it on the firmware and matched it on the driver

13

I even tried to re-download the latest marlin firmware to make sure it wasn’t a bad download.

14

Did you change the baud rate in the Marlin firmware?

15

Driver should negotiate. Only set it in the firmware. Did you drop the baud rate in the firmware?

16

I just tried it again and still nothing. I changed the baud rate in the firmware and it says it’s successful but I am not able to communicate with it from anything other then the arduino software. I know it is working because if I send the test file from the reprap wiki all lot or move and everything. I also tried to hook up a display today with no luck just a blank screen lights up but that is not a must I prefer to use octoprint. I will try a older version of Marlin later to see if that works also.

Tried a different usb cable?
