Problem Firmware KIT K8203

K8200 3D Printer
1

Good send you this post to make an inquiry, it turns out that I have a 3D printer model k8200 and I just purchased an update of a kit K8203, and I made all the assembly without problems, until I get to the step of loading the firmware, it turns out that when I go to the 2 phase of installation: https://manuals.velleman.eu/article.php?id=358 I proceed to download the firmware that you provide me, I install the latest version of arduino, and I open the downloaded project from your page, I configure the model of arduino to mega 2560 and when I give to compile the project before loading it into the arduino, it gives me an error in compilation, and I do not know what to do to solve it. Can anybody help me?

This is to Error:

Arduino:1.8.5 (Windows 10), Tarjeta:“Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)”

You will need to make sure the file is unzipped.
Short the JPROG connection
You can only use Arduino version 1.0.6 or lower for the K8200
You can download it from here.

Thank you very much for the help, I was able to load the new firmware and I reset the eeprom with the verison of repetier host 1.6.2 that I downloaded from the page of velleman, but the problem now that the X axis does not work, the Y axis and Z if they work well, but the X axis does not move in any direction, someone knows why it can be, if it is for the firmware? The firmware version is as follows: firmware_k8200_v2.3-marlinv1

Did the printer work before you installed the K8203?

5

before installing the firmware it worked perfectly, when installing the K8203 kit and the firmware update, the X axis stopped working

6

are you 100% sure you installed with arduino version 1.0.6?
Because in the logs it says 1.8.5

7

The problem was with the version of arduino 1.8.5, but when Wrong_Way told me about the arduino version, I changed it to version 1.0.6, and the firmware was installed without problems, but when I made the step of the eeprom , and I’m going to test the printer stops working the X axis.

8

Can anyone give me any advice? I continue with the printer without working

9

After you used the Arduino IDE to upload the new firmware, did you do a “restore defaults” in the Velleman/ Repetier software (under config in the menubar, restore EEPROM)

10

I have used a previous firmware, and I have managed to make everything work, now the problem I have is that the extruder, goes the other way, instead of putting filament extract it. Can someone tell me where to change the direction of the filament?

11

I have looked at other questions in this forum and I have solved the problem that the extruder will work in reverse, now I realize that when I print the printer, between lines it leaves a lot of space and if I touch the extruder’s motor it seems that it is jumping, someone knows if that has a relationship? or do you have to touch some extra configuration?

problem solved, the cause was that I had the temperature of the extruder low. Thank you very much for the help
