[Pre Print nozzle purge]

Is this with the same GCode-file? Are files prepared with cura, if so, which version and have you set the GCode flavour to UltiGcode for all machines? Have you tried doing a factory reset on the printers?

 

Different GCodes but I have never setup these in cura outside of layer thickness etc.

I am using two different versions of cura depending on which laptop I use. I will take a look at the setup of both and report back if I need more assistance.

Maybe ask around and see if you can get a few meters from someone to test with?

Prepare to spend a lot of time tweaking settings. Also, using the stock feeder is a crap shoot, it could work if you're lucky or it might not.

 

Thanks Robert,

Fortunately I am not paying for material out of my own pocket so cost isn't really an issue but time is...

I'm going to buy a role but most likely I will be back on here asking about optimal settings. Someone did mention that your feeder is best suited to this material so I will probably print this first.

Do you have a few revs of your feeder or is there just one design on youmagine?

[Pre Print nozzle purge]

Hi,

I have 4 UM2 printers all running on the same version of firmware yet they don't all do the same thing when it comes to their pre print routine.

Once the bed and nozzle have reached temp and the build plate rises to begin printing I am seeing the following on different printers

1. The nozzle will purge (dispense material) onto the front left hand corner of the glass and then printing begins

2. The nozzle will purge while moving to the start position of the print job

3. No purge will happen

Is anybody else seeing get these differences while running the same version of firmware?

Is this a friend ware issue or does this get setup somewhere else?

You can do it. I printed it on a stock UMO+. It's kinda like a wet noddle inside the tube. but it somehow works. You need to slow it down to about 20mm/s however. And it feels like you're printing with nozzle ooze. but it works.

Here's a Mic Shim I made for an FS7

And a bency (middle)

The others are woodfill and bronzefill.

The finished texture is like a slightly pourous rubber. I could be under extruding or going a little too fast however so mine has a bit more air gaps than normal.

You can use this to your advantage though. If you purposefully under extrude you get an even softer shape. It's also quite strong, it stretches a decent amount and difficult to rip.

Most people recommend Rober's extruder if you plan to print on a UM2.

 

Thanks Valcrow, think I'll give it a shot. What's the worst that could happen

[NinjaFlex - is it worth it?]

Hey everyone,

So im thinking of buying a roll of ninja flex to try some different styles of printing. They dont really recommend using the filament on a bowden style printer but I dont tend to let stuff like that deter me.

So im wondering before I make the purchase is it worth it or will I end up having to do endless tweaks for shitty resuts?

Also, what are the finished products like? Im hoping it finishes sort of grippy so it could be used as feet or as a corner protector if you know what I mean.....
