Enormous prime/retract

[Loïc Fejoz]

Hi,

I believe there is a serious bug in the prime plugin.

In attachment, you will find what came out of a simple example of a box.
Just to let you understand my model:

• Brush 1 is normal one,
• Brush 4 is perimeter only, (to simulate Slic3r contouring),
• Brush 3 is slow printing (for first layer).
  

First the prime and retract tags are not commented (missing ; )!
Then the first retract is normal and quite small:
(<retract>)
G1 F2400 E3,634
(</retract>)

But at one point, something really unexpected happens!
(<retract>)
G1 F2400 E240,344
(</retract>)

It nearly remove out the filament from my printer.

Regards,
Loïc

Hi Loic,

Sorry you are having this issue, I am looking into it right now. I made several prints on an UM2 and a Rep1 to test the latest release, and had no trouble. So this might be an issue with the printer profile. I'll come back to you soon.

Hi Loic,

Here is a corrected profile (to replace printer.lua in gcode/foldarap) ; I'll push an update asap.

Other affected profiles are:
- reprap
- ultimaker 1, only when using dual extruder

Thanks for pointing this out!
