Simplify starts at line from 201 - prusa i3

[Jaroslav]

Hi,
I am new to 3D printing. I have a problem start using the S3D with my Prusa i3 1,75mm.
First of all, there is no Prusa i3 profile (but on thi web is listed that is supported, ?) would anybody recommend any alternative?
I created my own profile so far.

But when I start simulation, the nozzle starts moving after 200 line point. Till this point, it stays at 0,0. When I generated the .gcode and started printing, the printer made a huge blob that clog nozzle with the filament. So I stopped the printing. I suggest that there might be some connection between the preview line not moving up to 200 and this flow.
So far, I used Slic3r that pours also a little of filament at the beginning, but during moving from 0,0 to the first layer. Not like this.

Thanks for any help.

If you click "Save Toolpaths to Disk" you can save the gcode file to your hard drive and then open it in a text editor. The first 200 lines are just comments, so that's why there is no movement happening there (this is normal).

It sounds like you may want to edit the commands in your starting script to change the purge sequence for your Prusa at the beginning of the print.

Hi, thanks for your reply. Maybe I dont understand clearly. should I delete first 200 lines from the gcode?
I dont understand coding. It does not look like I can delete something.
Counting every time 200 lines to delete before printing is not very comfotable and safe I gues

You don't need to make any changes. It is normal to have these comment lines at the top of the file.
