Re: Problems with PVA and dual extrusion

Re previous post.
I just checked the CURA 3.5.1 default settings;
Nozzle switch retraction distance; 16 mm
Nozzle switch retraction speed: 20 mm/sec

That is with ABS, but I don't think the material type matters, only the dimensions of the filament paths in the Y
FWIW, etc.

Re: Problems with PVA and dual extrusion

I am trying to do this on an Artemis, well not quite this I am trying to do it with ABS, so different material and somewhat different hot ends. Anyway, I noticed mention of tool change retraction of 3 mm and that seems extraordinarily SHORT (to me). I'm thinking that each material needs to get fully...

Re: 2 Color printing with CURA

I'm still trying to slog through this, MOSTLY for 2 material printing so that I can use water soluble support material. I avoid it for a while, then create an object that needs internal support that would be very hard to remove with pliers. Right now I have both extruders responding to elementary co...

Curious;
Dassault Systems - - a French company ?
Yet this program is available to US and Canadian ex-Military ONLY.

Maybe their French and/or German and/or Italian and/or ...web sites offer similar programs ?

Re: Duet Web Control with Webcam

Thanks, but for what I want to do and how I want to do it I think a simple wireless web cam will suffice without adding any burden to the duet.
Just another browser tab or window, maybe split screen or tiled.

Re: CURA

The "solution" to the problem I was describing above turned out to be the infill support setting. It SEEMED like a good idea to have infill support, but I either didn't read or didn't digest the word "only" in the description. It DISABLES infill EXCEPT where needed for support - ...

Re: Tech Support Needed on Z-Probe Always Triggered

I just noticed that THIS is the Rostock v3 sub forum - and that the OP and I have been talking about SE300 problems.

While I'm not absolutely "up on" which machines can have which Z probes... I thought the Max was restricted to SE280.

Maybe it doesn't matter too much.

Re: Tech Support Needed on Z-Probe Always Triggered

Continued from previous post; I just finished about a 3 hour print and the blue probe light stayed ON until the extruder cooled to 48 C (from 235). During that time the Z-probe sensor read 1000 most of the time, but flashed 875 a couple of times a minute, and more rarely showed 937. Once it went out...

Re: Tech Support Needed on Z-Probe Always Triggered

I seem to have a similar symptom to the OP (original poster). When the hot end is HOT the blue probe light will come on and it takes a LONG cool down time before it goes off. Example; Room temperature around 23 C I switched on the printer and intended to change filament, so I turned on the extruder ...

I can't edit the above post, but had meant to say that in Solidworks "mate" will help you figure out where and how your joints don't fit, e.g. a sliding dovetail needs to be right, and I mean JUST RIGHT for the assembly to go together. It can still be worth taking off a TINY bit from each ...

Re: 3d model slicer software

Ahh yes, "massive" builds". Not usually the domain of 3D printing, but it CAN be done. I'm going through this now, since the PRACTICAL limit on ABS prints is about 10 cm - above that thermal stress and shrinkage cause cracking and/or deformities. Solidworks can do it; basically you wo...

Cura is the recommended slicer for Artemis, so we should probably have a thread for it. I have been using 3.4.1 - which is a bit later than the version mentioned in the Artemis docs. Today I got an automated notice that 3.5 is available - and an invitation to download it. Anyone try this yet, either...

Re: 2 Color printing with CURA

That seems like a whole lot more trouble than it would take to modify a slicing program to at least switch extruders for support material and/or at layer numbers.

Anyone know of slicers that CAN do that ?
slic3r for example, or matter control ?
