Re: Best fasteners for ABS cases?

I have used machine screws and hex nuts on such cases as follows. Where the hex nut is to be mounted, create a column somewhat wider than the nut, create a hole down the column that equates to the screw O/D. Print the case Assemble a nut onto a longish screw, heat to around 300c and slowly push the ...

Re: PMMA sheet as print bed

Wayneuroda, The platform heater on the up plus is just thermostatically controlled to a 100c set point. The software displays it but does not hold back printing regardless of the actual temperature. It is only the extruder temp that is monitored and prevents printing until it hits the desired temper...

Re: Noise

"pepping", could alternatively be moisture in the ABS. As the filament hits the extruder heater the 260 degrees will instantly vaporize any moisture and this sounds like a little intermittent popping noise. ABS will absorb some moisture so best to keep the filament in a dry atmosphere.

Re: PMMA sheet as print bed

jena67,
OK, if it is plexiglass, that is also, here in the UK, known as Perspex or Acrylic sheet.
i have not tried it but may well do so in the future.

Re: What is the realistic maximum model size of the UP Plus?

not sure what the modern standard for platform is, but the original UP and UpPlus had an anodised aluminium platform that was bolted to the structure and as it had no clips allowed a full 140 x 140mm. Now I know that the plate itself even with the UP paint was not too good at adhering to the ABS, ho...

Re: WANTED: Motorized filament feeder

the filament feeder, mounted above the filament reel is just a stepper motor sense switch and a microprocessor to determine a fixed number of feeding steps. As filament is pulled by the extruder motor a slight tension at the filament feeder activate a switch which causes the filament feeder stepper ...

Re: Looking for parts

Kastro, The stepper motor type filament guide is not needed, it was replaced by a passive guide some time ago. So long as the reel of filament is free to rotate then the extruder motor has more than enough pull to feed the filament. Soooo, you could do the following. On your existing filament guide ...

Re: Filament not sticking to platform

Plus with 2 sheets of 90gem paper A4 or A5 you can move the extruder from centre to each edge and instantly "feel" if the grab is similar. As the paper will cover the entire platform.

Re: Printing raftless for smoth surface Problem starting

I have always used Kapton Tape. ABS sticks to it very well. Not sure why anyone would recommend an adhesive on it, unless they had not cleaned it the first time around with acetone or MEK. This is very important. As supplied, a roll of kapton tape has a microscopic layer of release agent on its surf...

Re: Yet ANOTHER Flexible Filament

I looked at this Ninjaflex on their site, price up front in the UK seemed reasonable, but as you progress through the order they add £15 shipping then 20% tax on the lot, a bit naughty not advising this up front. So a £31 reel of 1.1lbs ends up at around £55, Others ship 1Kg reels of material in the...

Re: Printing on an object

I have not tried what you are attempting, but would assume the following. 1, Ensure the pcb is flat over its surface and lays equally flat across the platform. Hold down with some form of clips. 2. The pcb may take longer to heat than the base, however many use perfbaord anyway, which is effectively...

Great to learn of your comparison. A couple of points re the UP.

You can turn on the bed heater in the maintenance window as soon as you have initial...
