Rostock 301 delta radius problem

[Renan]

Hello to all!

I bought and assembled one Rostock 301 and now I'm having some problems with the calibration step.
Following the tutorials and manuals on the internet for this model, I configured the G-Code for 4 scripts on my repetier software.

the first: G0 X0 Y0 Z2
second: G0 X-73.61 Y-42.50 Z2
third: G0 X0 Y85 Z2
fourth: G0 X73.61 Y-42.50 Z2

After calibrate the second, third and fourth points, when I run the first g-code, my nozzle had to be positioning 2mm from the base. When click 2wice on the -1mm button, the nozzle must "touch" the hot base.

The problem is: After the configuration, my nozzle doesn't touch the base on the script 1 (X0, Y0, Z2 after pressing twice the -1mm button).
I saw on a tutorial movie, that I've to configurate the firmware, increasing the delta radius because my surface is concave.

I made this configuration, but, changing the delta radius, nothing happens. I changed to many values without success.

How can I configure the delta radius correctally? Sorry my english errors.

Thanks in advance.

Hi William,

Ty for your reply! I read your link but didn't help me.
The problem that i've is about the delta radius configuration on the firmware of rostock 301.
This firmware is closed and I don't know if I can install an alternative to it on my 3d printer.

Btw, configuring the delta radius into my printer settings, nothing happens.

If someone know how to solve this, please contact-me!

Ty!
