Re: Tool change retraction not done on first layer

I have posted much text, but the bug is really simple. With dual extruder, the Tool Change Retract and Tool Change Prime (i.e. restart) are not applied on the first layer. Of course, you don't need to do a Tool Change retraction and prime for the first extruder on the first layer, because it starts ...

Re: Using variables inside S3D

All, I noticed that merely referencing a variable in a script can alter the slicer behavior (i.e. it behaves differently than it would you entered the same number as a constant rather than as a variable name). So use with caution. Details are posted at: https://forum.simplify3d.com/viewtopic.php?f=9...

Re: Tool change retraction not done on first layer

OK, I made some progress to work around this. But I think this is a bug and should be fixed. I am using S3D 4.1.1. The only workaround I could get to generate correct Gcode is the following. My T0 is printing first, and T1 is idle first, so what is missing in the Gcode is a retract of T1, and then a...

Re: Dual extruder, collisions between support and ooze shield

Yes, I do....for that Gcode I set the Extra Inflation Distance to a large number and the ooze shield "Offset from Part" to a small number to show that it is possible for lines to conflict. One possible answer is that there is no automated check for this and I am just supposed to avoid this situation...

Tool change retraction not done on first layer

After watching the printer and looking over Gcode, I find that my inactive extruder is leaking a lot on the first layer, and that this is because it doesn't do Tool Change Retraction on the first layer. My start script ends with the filament fully primed in both extruders. So as T0 prints, T1 leaks ...

Dual extruder, collisions between support and ooze shield

I am printing PLA on T0 and PVA on T1. One each layer, it lays down the PLA main structure before the PVA supports. There are many situations where I see the PVA line crossing a previously-deposited PLA line on the same layer, or even crossing other PVA lines on the same layer. I don't see any inter...

Re: S3d code for Taz 6 v3

Yes, that makes sense, I am doing the same. I got things mostly set up and had a good test print, but found some problems: 1. I found that using M218 T0 X-6.5 and M218 T1 X6.5, the negative value didn't register, and so my extruders were off by 6.5mm. Maybe negatives just don't work here. But anyway...

Re: S3d code for Taz 6 v3

If you copied the beginning of the start code from CuraLE, it expects the firmware offsets to be zero so the M218 goes at the end. OK, this is a good idea, I think I will do it that way. If I understand the above, you mean that the Start Gcode from Cura that does all the wipe and bed leveling expec...

Re: Tip of the Day 18 - Advanced Tab, a technical analysis

UPDATE - I have version 4.1.1, and it is NOT on the Advanced Menu. It is at the bottom of the "Other" menu now.

Re: Using variables inside S3D

Did you ever get any answer to this? I have similar request, for similar reason. For example it would be nice during a tool change script to set the inactive toolhead temperature to its print temperature minus 10 degrees. Then if I modify the profile to a different print temperature, the tool change...
