My   Printrbot   Simple is ready for the induction probe (should get it

My @Printrbot Simple is ready for the induction probe (should get it this week) with a nice aluminium bed. Got a nice big sheet of 3mm thick aluminium.

Currently printing this support for the probe:

Haha nice that thing is huge! That heatsink on the e mirror is a bit of overkill isn’t it?

@Aaron_Kable Yeah it is. Tried it cause I had it laying around but does not do much more than the fan alone. But it looks cool LOL

Haha it does look awesome. I’m waiting on my longer rods so I can install my x and y upgrades. Then I just need to find a nice price of ali like that :slight_smile:

What sort of speeds you got it running at?

There are my typical Slic3r speed settings:

Andres-MBP:~ courchea$ cat ~/Library/Application\ Support/Slic3r/print/0.3layer_0.2fill_honeycomb_fast.ini | grep speed
bridge_speed = 50
external_perimeter_speed = 70%
first_layer_speed = 80%
gap_fill_speed = 20
infill_speed = 50
perimeter_speed = 50
small_perimeter_speed = 40
solid_infill_speed = 50
support_material_speed = 50
top_solid_infill_speed = 50
travel_speed = 100

Anything above 55 creates a lot of vibration and noise.

Yeah that is almost exactly what I use

The name of the game might be weight. It seems there’s a lot of excess weight on the X and Y axes, you should see better performance if you could reduce that.

@Jeff_DeMaagd The Y mod I used is this one:

Even with the extra weight, I did not see any difference as far as performance or reliability.

I bumped my Simple’s table to a 200x200mm mirror. The mirror was larger and clipped to a thin piece of plywood. I found it wobbled excessively and so I went into the firmware and dialed down the acceleration from 2000 to 1000. I also print at ~20mm/s. I’m getting nice results - I’m actually printing Emmett’s transmission - http://www.thingiverse.com/thing:34778
