Dual color with pause. Flashforge dual

[Accessdenied]

Hello. I have made two colors model, first part is flat square, white color, 0,6mm height with 3 layers of 0,2mm resolution, on this I should have black text with 0,4mm height. While printing black filament is making dirty my white base. So I need to print white base with cold second extruder, then rise up printer head, start to heat second extruder, manually clean white nozzle and start to print my text with black filament after some minutes. So its a question about such pause to clean white nozzle, cool down it and start to heat black filament head and continue printing on 0,6mm height. How to do it?

That sounds like a tough one to be honest. However, what you could do, what may really improve print quality would be to place a tall skirt around your part. Under the layer tab, set your skirt layers to 99999. It will generate a skirt as tall as your part, and this skirt generally does a great job at catching ooze.

A S3D "Skirt" is pretty much what Makerware calls a purgewall?

Also under scripts you can use the tool change tab to retract extra filament on the [old_tool].
There is a forum post on that somewhere.

(But you know what... I have a flashforge too and I still use makerware for dual color prints... sorry S3D isn't there yet... but I hear they're working on it.)

Thanks, seems that no way to do that while they didn't make such option..
Skirt perhaps is an idea, but it doesn't improve material consumption for sure.

What is the way you use Makerware for dual color prints? Is there an option for pausing and head moving on Z axle or you just using standart options with additional walls?

I just use the purgewall feature. It does a few things:
1) prints a wall on each edge of the print with buckets on the end of the wall. One wall for each color.
2) at tool change, retracts a large amount of filament from the nozzle about to go idle and wipes that nozzle over the wall
3) purges material from the new nozzle into the bucket and prints a layer on the wall which ensures plastic is flowing from the new nozzle for the layer about to be printed.

I'm not sure if the time to print the purgewall counts as the pause you're talking about or not. for z axis I'm not sure if they have a lift while retracting feature or not.. haven't looked for a while. But the above has been sufficient for my needs. I've done black material with white support material and had no problem with the two plastics bleeding into each other.

Well, I have printed it with Makerware also. Had some small black soil. So I set nozzle temperature at 200C. Bit too low and some small details didn 't print like I wanted (text on white surface), but it avoided dirties..
So I would like to wish for Simplify3D to make powerful tools for dual color printing, like smart algorithms for nozzle cleaning with purge walls, retracting and nozzle Z moving top to clean nozzle dirties manually (small pause on some height) and option to disable one nozzle heating when second one comes to print.. somethink like that. Then we would be able to make clean dual color print for very precise details liek buisnesscards.

Many other posts on this topic already. Supposedly the next version is going to address dual head printing.
