Slow down first layer after raft and support

[72LSx]

I have been playing with HIPS/ ABS printing on my flashforge creator pro. I got ABS/ HIPS to work, with one exception. I am looking to slow down ONLY the first ABS layer after my HIPS raft and all first ABS layers directly after a HIPS support.

Is there a way to do this?

I know how to speed down the first layer, but this is just the first layer on the bed, the first layer on the raft prints at normal speed. Same with the first layer after support.

Thanks for any suggestions

Why you want to do so? Any problems?

The slow-down for the First Layer when beginning the print, is needed for better sticking on the bed.

With HIPS as the material for support, you don't need separation-layers.

I think you can already adjust the perimeter speeds and the bottom solid layer speeds, so that's an option if you want to make an adjustment right now.

I have issues with the ABS sticking to the HIPS. If I slow down the print speed the ABS has time to stick and not be pulled. I could slow down the entire build, but we are talking by about 50-66%, which adds a lot of time. I have no issues with the HIPS or ABS sticking to the bed.

Ah, ok! But I can't see the problem because I think that the melted material leaves the nozzle as quick as the printhead is going forward. And that very exactly. I premise that the quantity of extruding of ABS is ok, optimally there is a very small bow wave in moving direktion .

An other idea: is it possible, that S3D interpret the crossing over the Hips as bridging? Then you may justified in the Other-Tab the full speed but only 50% extruding.
