UM2, 2 nozzles and soluable support

Recommended Posts

Posted (edited) · UM2, 2 nozzles and soluable support

Hi all

I've sucessfully modified and printed in two colours with a UM2 with two Olsson blocks.

I've been experimenting with PVA soluble support with varying degrees of success.

I've used Cura 15.xx with success but this does not allow for two printing independent speeds ie model and support. I've also tried various options/printers in Cura 2.6x without success. When selecting Ultimaker 2 Dual there is no provision for separate speed for extruder #2 (PVA) but the support is printed from extruder #1. I've reconfigured the settings for UM3 to the ones for UM2, added the second extruder and this gives  me the option of different speeds for the model material and the soluble support but it doesn't perform as it should.

So the question is where am I going wrong?

What am I missing in either or both versions of Cura?

All help welcome.

Thanks

Graeme

If you just added 2 Olsson blocks to a standard UM2 then your problem might be due to too much heat transfer from one nozzle to the next. This was one reason why UM did not progress with this option.

What are the issues you are having with PVA? pictures?

As I mentioned earlier with Cura 15.xx both nozzles work as expected but from reading on these pages a slower speed is required for the PVA as to the PLA, Cura 15.xx doesn't seem to support.

Cura 2.6.x does but when I select Ultimaker 2 Dual there is no facility for reduced printing speed on the support nozzle so it just supports from extruder 1. Neither does Ultimaker 2+, Ultimaker 3 does but prints a second prime tower with extruder 1 instead of extruder 2 (under but default was Reprap so I changed this to Ultimaker 2 under the profile setting).

I'll upload a picture later today.

This pic shows the first layer. The square in the top right is the wipe tower for extruder 1 (PLA) followed by the circle. The the head moved to front just to the right of the small dot at the front right of the heated bed, then moved to the back for the second sqaure (the one on the left) I assume this should have been the soluble support wipe tower. It was at this stage that I stopped the print run.

This second pic shows the printer profile settings.

I hope this gives some insight.
