The temperature of my printer does not higher than 235 degrees. I cannot load ABS because of this.
What can I do to solve this problem?
How can I lower the temperature for loading ABS to 230 C?

Temporary tip : Slow the fan with your finger.
In configuration.h of the firmware look for this :
// Preheat Constants
#define PLA_PREHEAT_HOTEND_TEMP 210
#define PLA_PREHEAT_HPB_TEMP 0
#define PLA_PREHEAT_FAN_SPEED 165 // Insert Value between 0 and 255
#define ABS_PREHEAT_HOTEND_TEMP 245
#define ABS_PREHEAT_HPB_TEMP 0
#define ABS_PREHEAT_FAN_SPEED 165 // Insert Value between 0 and 255
You can lower the temp and/or the fan speed
Or you can do it in the LCD menu with the settings.
Cheers,

I have changed the setting pre heat nozzle 1 to 230 but with the load abs still 245 C is used.
Edit ULTRALCD.CPP
Search (ctrl-F) for 245. Change all 245 to 230.
You don’t need to do that. You can define your own filament profile in the Cura config in Repetier Host. Copy the defaults for Velleman’s ABS and rename it, save it and make sure that profile is loaded.
This will let you lower the ABS temp and change the fan speed during a print. It won’t affect the fan speed during pre-heat for ABS. For that, go to the start gcode in your new ABS filament profile, and change the value:
…
G28 [color=#408000]; Home extruder[/color]
G1 Z5 F{Z_TRAVEL_SPEED}
G1 Z0 F{Z_TRAVEL_SPEED}
M106 [color=#FF0000]S80 [/color][color=#408000]; Turn on fan, changed from S165 to speed up heating![/color]
G90 [color=#408000]; Absolute positioning[/color]
M82 [color=#408000]; Extruder in absolute mode
; Activate all used extruder[/color]
…
AFAIK, the start G-code is not used when loading the filament from the LCD, only in the G-code generated by Cura.
Did the OP state that he was only printing from the LCD? I missed it.
Whatever, he still has to slice his object somehow, and that gcode will determine the behavior of his Vertex. Recompiling the firmware seems a bit of a drastic step… I wouldn’t recommend that to someone who’s struggling to print in ABS due to bad default print profiles.
His primary problem is that he can’t load ABS in the printer because the nozzle can’t reach 245°. The automatic load command is in the LCD Menu. Of course you can always load the filament manually from Repetier.

Ah, OK. My apologies!
I had problems reaching 245 C for loading via LCD also, and the sensor is mounted correctly. I found that slipping a paper under the top fan (between the fan and the Y-axis bar) was all I needed to reach 245. Once loaded, the Repetier settings take over, where the fan speed is set in the G-code.
