Howdy all- Awesome program so far. Definitely sold on Simplify vs Rephost/slicer.
My question is while trying to print some tests using FlexPLA (Ninjaflex), as many who have tried know, it's difficult due to the flex prior to the hot end. I've managed to use the machine control page to play with temps & extrusion speed so that I can now get a consistent flow. My challenge is that the "processes" only allow overall speed changes. How can I have the software create the gcode based on a maximum extrusion speed of say 60mm/min?
Thanks! Keep up the good work
Re: How to restrict speed by max extrusion speed? (Flex)
I'm working with this problem too. I believe the answer is in putting an M203 command in your startup script. For example M203 E5 will set the maximum extruder feed rate to 5 x 60 mm/min, or 300 mm/min. So in your case M203 E1 should do the trick.
It seems to work like it says when I jog the extruder, but I'm not yet at the point of being able to print this flex stuff so I'm not 100% certain this is right.

In my experience the default printing speed is the only setting you need to adjust the extrusion speed. I've set it at 1800mm/min for Ninjaflex and it prints fine.
Re: How to restrict speed by max extrusion speed? (Flex)
I've been able to print flex filament successfully now using the M203 E1 command before doing any extruding, and also putting it in my start script. At the same time, I set the print speed at 900 mm/min. I'm not certain what the effect of mixing the two ways of slowing down the print is- I guess you could do a calculation of some kind and figure it out.
Anyway, it worked. The other things I did that might have helped was turn off retraction, and don't use any underspeed on the perimeters or first layer. The idea is to keep the filament extruding at a constant rate and pressure. Also, I didn't set the z-height as close as I usually do because I was having a problem with the filament backing up. The print I did stuck fine to a glass bed that had been treated with a dilute solution of elmer's glue.
The filament I'm using is a Flex Polyester from plastic2print in Amsterdam.
