LCD display has just arrived, but a bit confused as how to download the software to drive the LCD display. What are the correct download links I should use and how do I go about it? The LCD is already mounted and connected to the printer control board. Thanks Don
Hi Don,
it is possible that you already have the “V2” firmware installed (it’s default on most controller boards by now).
Do you see anything on the display yet? Perhaps an adjustment of the contrast (poti on the LCD board) may be necessary.
Another short test whether it’s “V1” or “V2” (both show up as Marlin v1 in the log): starting at Z home, send G1 Z10 F300
G1 Z20 F450and observe the movement. If there is a notable difference in the speed, you have the “V1” firmware, if it’s the same for both parts, it’s “V2” (which has F300 as Z max feedrate).
Cheers,

you can download the firmware with this link k8200.eu/downloads/files/dow … rlinv2.zip
and follow the following link to the instruction for installing the fimware : k8200.eu/manual/printing/?c=007
EDIT: Gave the wrong link
If I may: “V2” firmware including LCD support should be k8200.eu/downloads/files/dow … rlinv2.zip
Whoops thanks kuraasu =)
Was early in the morning 
Beware of installing these LCD firmware. If you flash something else could be also V1 without lcd support than your board could be ruined. I had this case. Both firmwares doesn’t worked for me! before the flashing everything was fine. So i would give you the advice leave everything as it is, put the lcd display into the garbage and do not put velleman power supply into direct sunnlight. Also DO NOT ORDER ABS support material! Only PLA should be printable well with K8200 printer. I’ve done reprap modification so i can now also print ABS support material. Even if it seems good if you print this few meters test material after months you will recognize that thermal deformations occure. I think it is because of the heating bet which can only heat up to 60-65°C but for ABS you need at least 80-90°C
Best regards
Hi venis,
sorry to disagree, but I have been printing ABS successful without any major modifications to my printer. Only placed a mirror with kapton on the bed.
I start with a bed temperature of 60°C and raise it to 70°C after the first layer so the printer won’t take too long to start printing.
ok, you have to give it some time, but it works.
It needs some time to ‘master’ the tricks of printing ABS, but it can be done.

there is a difference between both commands 1st one is slow whilst 2nd one is faster. Tried the pot, just “brightens” the display by making 2 rows of little rectangular blacker spots on the display
Hi crash69,
then your controller is still running on “V1” firmware. Follow the instructions given in the link from VEL337 to change the firmware. For the “V2” firmware, the Arduino IDE should report 102,326 Bytes image size after compiling. Note that in Repetier Host, you will still see “Marlin v1” in the log, that’s ok.

@Venis: Please keep a positive attitude. If there is a specific problem, please let us know and we will deal with it.
