General Discussion / Re: Base Height
« Last post by Stuartblarg on December 13, 2014, 01:25:36 AM »
It looks like they may have removed the option in an update to the software, as you have noticed the picture in the manual is different from the current UI.

It's possible that the fuction has become obsolete because the printer builds only the amount of raft that is necessary and minimising it further could cause the job to fail.

There is an option for "Support - Dense: This represents how many layers of ‘solid’ (dense) material form part of the support structure directly beneath the model. Default = 3 layers" im not sure if lowering this will get the outcome you desire, you can only lower it by one layer so it wont make much of a difference.

Sorry if this wasn't the answer you were looking for.

General Discussion / Base Height

I have asked the following question before and disappointed by the support with no answer...

I don't have "Base Height" here!
In the pdf manual file "Base Height" exists on the right hand side of the "Z Resolution" but on the software there is not such a thing!

Please help I wan to reduce the raft thickness

UP Mini / "Printer Disconnected" Computer wont recognise 3D printer
« Last post by Stuartblarg on December 06, 2014, 03:41:04 PM »
So i turned on my UP! Mini today to find that the computer no longer recognises the it is plugged in. I recently unplugged it from the computer to clean my PC out but when i plugged it in again I no longer get the jingle indicating that a USB device has been plugged in.

The printer itself still turns on and holding down the button still initializes but the computer doesnt see it. I have tried turning it off and on, turning it off overnight and plugging it into other computers but all to no success.

Im pretty sure this has happened twice before and both time resulted in me sending the circuit board away to be replaced but now my warranty is over so i have to come here for advice.

Some research suggest that it might be something to do with static electricity frying the cpu but im not sure if there is anyway i can check that.

Thanks for any help

UP Plus / Re: raft sticking and fan door
« Last post by jt1991 on November 10, 2014, 06:41:20 PM »
I reckon the problem is the Premium material.  I had the same problem and it went away when I managed to get some "Original UP" filament. See my post Oils aint Oils and  ABS aint ABS.  Back to back test with the same settings and the same part and the difference is the original support material peels away with ease and the Premium does not - to the point of taking the first part layer with it and exposing the internal honeycomb structure when it deigns to come away.

UP Plus / Thread width
« Last post by ccidesign on November 05, 2014, 09:45:58 AM »
Hi All,

Been reading through the specs of the Up Plus 2. I'm just wondering if anyone knows the thread width of the Up Plus 2. I think this would help everyone when it comes to getting designs right the first or second time.
Really heart breaking when you get to the 7hr of a print and right at the top the print fails because of a feature to small to print.

On another note what is the smallest feature people have be successfully able to print with their Up Plus.

Chris.

UP Plus / Re: Fan on or off?

Thanks for the reply. 

I had read that part of the manual and researched the matter further afield.  I was wondering if anyone had some further advice or nuances beyond that in the manual. 

What started this was a sudden change in performance with a new (special) batch of ABS.  My prints went sour.  I suspected the material, but wanted to explore all options.  Since my first post I acquired some original UP ABS and printed parts with it at the same settings to compare with the "special" stuff.  I found my problems went away with the "original UP" material, and parts now print as they first did without my having to think much about any part of the print process.  See my new post of ABS aint ABS.

UP Plus / Oils aint oils and ABS aint ABS

I purchased some of the special offer ABS.  I had no problems with the original UP ABS, but all od a sudden I had problems removing the sacrificial material cleanly and with sticking to the perf board etc.  I persevered, with much searching and experimenting with door closed and door open and so on.  Things were so bad that separating the raft from the part bottom usually separated the first part layer, exposing the egg crate internal structure, or one was left with a very rough base to the part.. 

I suspected the new material had subtly different properties.  So I ordered some original UP ABS.

When the new ABS reel came to an end I was printing some S Scale railway signals, salvaging about one in two due the removal problem.  I mounted the newly acquired reel of UP ABs and with the same settings kept printing.  I find the difference very marked.  The raft and support material separates cleanly and separation during printing has vanished.  I now have 100% yield from the fragile signal prints, and larger prints have also improved.

Has anyone else had this problem or any comments?

UP Plus / Re: Raft is peeling off while printing!!!
« Last post by jt1991 on November 04, 2014, 03:21:13 PM »
Another suggestion is to dissolve scrap ABS in acetone to make a thin slurry.  Then paint this on the perf board before printing. 

I remove the prints with a 15mm wide chisel with a twisting action.  Parts come free easily.  Then scrape the perf board with the chisel held nearly flat, before the next part.  Takes less than a minute. .  Works better than the scraper as it is not so bendy.

I find this works like a charm.

General Discussion / Re: PLA or ABS?
« Last post by M528morgan on October 28, 2014, 11:47:02 PM »
If you’re beginner, I suggest you start experimenting with PLA filament. I use PLA exclusively because it emits fewer fumes and not prone to warping unlike ABS. Plus, PLA is easy to work with and does not require heat bed.
