@timcurtis67 you might be right. Any idea how I can reduce that shrinking?

It is PLA

Any Idea?

Hi I have an odd problem and am not even sure if there is a name for it. I am printing a frame that consists of a bottom plate and then walls with 5mm thisckness while the inner area is empty. What happens now is that the change from the bottem plate to the walls is clearly visible on the outer surface. It looks like a kink in the wall, like overextrusion for the first view wall layers... onyone seen that before?

Nice work around
Thx David!

Hi I noticed that the printer allways makes an automatic move to the saved return point after a tool change. Is that intended and necessary? I mean everone is free to have such a command at the end of tpost.g. For me it is makes everything more complicated... maybe it could be made an optional thing?

Hi I just had the idea it ould be awsome if the path to a spcific value would be copied in the object model plugin just by clicking on it. That way one could look for the value he needs and then copy and paste it into his gcode.

Greetings TC

@koreandi first you should manually switch between Tools using T0 P0 and T1 P0 and check if the Coordinates displayed in DWC change as expected

@Phaedrux thanks!

@deckingman You are right there are other ways to achieve it. I am asking also to maybe help improving the Firmware and if the purpose is to load and unload then still it is logic to assign the same type to multiple extruders

@deckingman yes that is true but still I don't understand the purpose of this limitation. When I assign a filanent to a tool I want it to know the print Parameters and nothing more. Why should I even want to create filaments of different colors?

Hi I am working with RRF filament assignment again and still can not understand why it is not possible to assign the same filament type to multiple extruders. Is there any reason for this and if not could it be changed? Or what exactly is the idea how to tell the firmware it has two PLA tools?

greetings
TC

@Kolbi Yes move.extruders

@dc42 Ah that is a nice idea. What would be the best way to store this information about a former retraction in RRF 3.1.1?

And are there more than 3 restore points? if so I could save the last position for each tool so it could go back to where this exact tool left the print last time.

@dc42 But is there a way to stop the printer from going back to restore point automatically?

@dc42 Ah thanks David. It would be great if the firmware could just know the next G1 command allready in the tpost.g file. That would solve the problem. I am doing it as you described. I even have a cleaning station but I am printing Pla combined with extremly flexible TPU so the ozzing is a serious problem.

@Phaedrux it is supposed to go back 20mm above the print and then it should go directly to the new starting point

Sure, would be awsome if you find something. I am a little under time pressure here

Hi, I am doing first prints with my new tool changer but i dont understand the behavior of the tool change procedure. The new tool allways returns to the point the other tool left the print and contaminates it with its color. It is doing it automatically, I have no such command in my tpost file. I want it to go directly to the point it is supposed to start printing... is there a wa to achieve that?
