Ultimaker 3 Profile PLA & PVA additional Tips

Wed Jan 11, 2017 10:08 am

This past weekend I opened my software to find that a new printer had been added to my configuration assistant, Ultimaker3! As I've had this machine for several months now, it is great to finally see a profile from Simplify3D. I hoped the long wait for an official profile meant that things would be fairly turn-key. I couldn't be happier. That said, here are a few things I've noticed that you may want to make note of before printing anything and everything.

1. If you do a lot of printing with PVA, you might want to take a look at dense supports in S3D. I will link to a video below that explains how to do it. It made a big difference with some of my prints and improved the surface quality above the support structures.

Personally, I've gotten good results using the same settings described in that video (5 dense support layers, 0.1mm horizontal offset, 0 upper and lower separation layers).

2. This isn't something that I personally use, but if you want to have the idle extruder cooldown between every layer when it isn't being used (I think cura does this by default), you can enable that in the Simplify3D tool change script. Just remove the semicolon before the last four M104 lines in the tool change script. If you want the print to completely pause until your set temperature is reached, change the 2nd and 4th M104's to M109's so that the machine waits to heat back up from the idle temperature. The default temperature set for idling is 170ºC, so if that's not what you want to use, you can just edit the M104's to use whatever temperature you want.

Again, I don't use this personally, since I have never noticed a significant quality difference and it makes the prints take a lot longer, but at least it's easy to enable if you want to try it out.

3. Finally, if you're someone that likes to tinker with your acceleration settings, you might also want to use different acceleration values for different materials. For example, you might want to reduce your acceleration and jerk settings for PVA and let the PLA extruder move a bit faster. You can do this pretty easily by putting the following code at the top of the tool change script (assuming your PVA extruder is toolhead 0).

Code: Select all
{IF NEWTOOL=1}M204 S1500
{IF NEWTOOL=1}M205 X15
{IF NEWTOOL=0}M204 S400
{IF NEWTOOL=0}M205 X5


There's a lot of neat things you can do with the scripts in Simplify3D, so if you want more reference info about some of these commands, I found most of what I needed here:

Hello DarthRevan,

I would really be thankfull, if you could me explain this bellow more detailed, what I have to do to get the temperature from the idle extruder down.
I tried it with your description, but it did not work. If possible send me some screenshots what I have to change. I use the Ultimaker 3 and have not really experience with 3 Printer. In the cura porgramm it is easy to do it, but with cura I cannot use the full size from the printer.

2. This isn't something that I personally use, but if you want to have the idle extruder cooldown between every layer when it isn't being used (I think cura does this by default), you can enable that in the Simplify3D tool change script. Just remove the semicolon before the last four M104 lines in the tool change script. If you want the print to completely pause until your set temperature is reached, change the 2nd and 4th M104's to M109's so that the machine waits to heat back up from the idle temperature. The default temperature set for idling is 170ºC, so if that's not what you want to use, you can just edit the M104's to use whatever temperature you want.

Thanks in advance
Best regards
David

This is what it should look like if you're not going to use M109 commands to wait for the temperature to heat back up.

This is what it should look like if you change the heating back up lines to M109(s).

This is where you would change the idling temperature. In this screenshot I changed the default of 170 to 185.
