Firmware - problem

K8200 3D Printer K8200 - Printer software (repetier, slicer, ...) a
1

Good day,

I would like to ask for help?

I’m hopeless.

I use the ballscrew 1204 on my printer.

Instead of 2,640 steps per 1 mm ascent

I must change 800 steps per 1 mm ascent / Z axis /

I found that I have to change the firmware with this setup.

Here’s the problem.

When uploading firmware via arduino unable to load the new fiemware.

On a site with instructions the procedure but apparently does not work for me.

The printer is a disaster …

Here is log - Arduino 1.6.3:

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer

Did you pay attention to short the programming jumper during flash?
Was the printer fully powered?
Which arduino version did you use? Only 1.0.6 works. NOT 1.6.0!
Did you select the correct com port and board type in arduino?
