Hi all,

I just finished building up my printer and it just looks awesome. My problem is when I play around with moving axis (X, Y, Z) everything is fine but I can't get any solution on avoiding the nozzle and extruder to touch the metal clamps on the bed (see attached image)

Is there a way to delimit the area where the nozzle/extruder can move? So that it never goes accross the clamps position. If yes, how can it still manage to switch the end-stops if the delimited area is small?

Any help much appreciated on that.

You can set the offset or specific printing area in the repetier-host printer settings / printer shape.

You can add this code to the startup script

Thanks, it looks like an easy way to do it. I have the mac version of repetier host (see screenshot).

1/ Is it "Dump area" that I should choose to change the settings?

2/ When I autohome, the printer will still go to the home position and get off the defined area? Should I stop homing?

I use windows version, looks a bit different , but the names are same.
Manually move the nozzle at the edge of bed and on LCD you can see how many mm is distance from home possition. This two values easy fill in bed left and bed front. Now you must check if you can reach the end of X Y axis. On my I3 pro B is not possible print on X axis more like 186mm. I have edge of bed 14mm and bed have 200mm, bud when i try move extruder to the end of X axis, then nozzle is about 10mm befor end of bed. Then i must set X max value, because when i try print large object like support for filament (180mm long) reperier make centr of object and start printing was outside bed.

Finally adjusted the clamps to stop precisely right before the white line printed on the bed. The nozzle goes freely now and doesnt touch them so no need for offsetting

Thanks !
