anyone update to the new software today?

The R2 has a nice onscreen UI for changing EEPROM values, so no need to issue commands directly

Running a test print at max acceleration set to 300 right now. If this works well (looking good so far!), I'll bump it up to 500 and see if I can tell the difference.

 

Here we go. Left cube is done with acceleration at 300, right cube at 500.



The right cube shows a bit of ringing, but much less than previous prints.

Speeds are severely affected, though. Whereas prints at the default settings finished around the 1h15min mark (if I recall correctly), the print at 500 took 1h44min, and the print at 300 took 1h58min.

Ideally, I'd want different accelerations for the perimeter and infill, but I think only Slic3r Prusa Edition has that option, and I've been enjoying Simplify3D so far... :-/

The following added to your Simplify3D Post Processing Script should set various accelerations. I plan to experiment with this on my R2 tomorrow.

{REPLACE "; outer perimeter\n" "; outer perimeter\nM204 P300\n"}
{REPLACE "; inner perimeter\n" "; inner perimeter\nM204 P300\n"}
{REPLACE "; solid layer\n" "; solid layer\nM204 P300\n"}
{REPLACE "; infill\n" "; infill\nM204 P800\n"}

Edited to correct syntax.

 

And the instruction sheet on how to get the stuff out shouldn’t be inside the unit. It needs to be on the outside of the R2. I laughed my ass off...

That's nothing uncommon today though - the standard is "go see instructions online" now...

 

Very nice, thanks, Ed!

It looks like the syntax changed for more recent Marlin firmwares, including the one the R2 is running, so it's now "M204 P300".
Here's what I set up and am now running a print with:

{REPLACE "; layer 1" "; max acceleration for first layer\nM201 X300 Y300\n; layer 1"}
{REPLACE "; layer 2" "; max acceleration for rest of print\nM201 X1500 Y1500\n; layer 2"}
{REPLACE "; outer perimeter\n" "; outer perimeter\nM204 P300\n"}
{REPLACE "; inner perimeter\n" "; inner perimeter\nM204 P500\n"}
{REPLACE "; solid layer\n" "; solid layer\nM204 P500\n"}
{REPLACE "; infill\n" "; infill\nM204 P1000\n"}

The first two lines use M201 ensure that the maximum acceleration on the first layer is 300, setting it to 1500 after that. Since this is a max acceleration setting, it overrides what's set with M204 if the M204 acceleration is higher.

I'll post the results once the print is done!

 

The print turned out good, and it was definitely faster than printing everything with acceleration at 300.

I noticed that I was accidentally printing everything at 100% infill (no wonder it was slow), so I am now printing at 15% infill. I also upped the other accelerations somewhat, while keeping the outer perimeters and first layer at 300.

{REPLACE "; layer 1" "; max acceleration for first layer\nM201 X300 Y300\n; layer 1"}
{REPLACE "; layer 2" "; max acceleration for rest of print\nM201 X1500 Y1500\n; layer 2"}
{REPLACE "; outer perimeter\n" "; outer perimeter\nM204 P300\n"}
{REPLACE "; inner perimeter\n" "; inner perimeter\nM204 P800\n"}
{REPLACE "; solid layer\n" "; solid layer\nM204 P500\n"}
{REPLACE "; infill\n" "; infill\nM204 P1500\n"}

Let's see how this one turns out!

 

This last one is showing a bit of ringing, so I'm going to set the inner perimeters back to 500. Need to run now, but I'll post some photos later today!

I'm using the following Simplify 3D Post Processing Script values with my Robo R2:

{REPLACE "; layer 1" "; max acceleration for first layer\nM201 X300 Y300\n; layer 1"}
{REPLACE "; layer 2" "; max acceleration for rest of print\nM201 X1500 Y1500\n; layer 2"}
{REPLACE "; outer perimeter\n" "; outer perimeter\nM204 P300\n"}
{REPLACE "; inner perimeter\n" "; inner perimeter\nM204 P500\n"}
{REPLACE "; solid layer\n" "; solid layer\nM204 P500\n"}
{REPLACE "; infill\n" "; infill\nM204 P1000\n"}

I also tweaked my Simplify3D ver 4 to take advantage of their latest features. For example, my Benchy has much better results at the top of the doorway & portholes due to the improved bridging algorithm in ver 4.

The Cube and Benchy bow have almost no ringing compared to the ones I printed without the Post Processing Script.

Benchy took 2.25 hours. The calibration cube took 48 minutes. Filament is MakerGeeks Silver PLA.

 

Anyone know a way to revert back after updating the R2 to the latest software? The site is less than helpful to find what is needed.

Is 1.1.7 the previous version. Looks like they have a link in the firmware instructions to that version. http://docs.robo3d.com/en/latest/R2/Troubleshooting/index.html#firmware-update

 

I imagine he's talking of the whole RoboOS, not just the firmware.
The only way would be reloading a card with a backup you had previously made.

 

Latest software, first print of this part, to be honest. I'm on the C2.

 

Benchy certainly puts a printer to the test

The scallops (bands) in Z make me think you may have:

1. Inconsistent extrusion? Try a different filament. Also use the Wizard to extrude a length of filament and verify the length is correct (by first marking the filament).
2. Partially clogged extruder? Clean it out.
3. Temperature variation? Try a PID tune of the hot end.
4. Bed wobble or vibration? Bent Z lead screw? Look for this as it prints.
5. Loose pulleys or belts? Check tension on all belts and tightness of pulleys.

 

If we're talking about the roof scallops... are you completely sure that this isn't in the part, as designed?

I didn't slice this, I just sent the GCODE file from the samples to the printer from the OctoPrint interface. You can't see it of course, but the deck of the boat is beautiful on both planes. Running my finger along all top surfaces doesn't appear to have this effect.

A lot of this was my inability to take a good/close/clear photo of the part. I'll try to chase a different lens for this.
