Re: Raft doesn't stick anymore

Studiocsro, If you set 121.8mm and the printer reports 121mm in the print or print preview menu, thenyou have not told the printer to set the correct height. Read the manual so see how to. Just telling the platform to go to a height smply moves it there to check. You then have to tell it to actually...

Re: [BUG REPORT] Heating platform stopped heating

This is a weakness of the design and has happened to many. After mine failed and as I mainly use ABS I made a new platform out of a sheet of Acrylic, ABS sticks to tthis at room temperature. Finally I repaired the heater wires as follows, firstly the original temerature sense wires were still good. ...

Re: Scaling of imported .stl from Cheetah 3D

Andy, I confess to not knowing Cheetah, however assuming the dimensions in the file listing you provided have no other parameters described elsewhere inch , cm or mm, the fact that the UP always assumes dimensions are in mm, it would see your file as being an extremely tiny object having a largest d...

Ninjaflex as a gasket.

UP,pers I have been experimenting using black Ninjaflex as a gasket material. Making 2mm thick gaskets I find these settings work best with an UP Plus. Extrude temperature 260 degrees.

Re: Scaling of imported .stl from Cheetah 3D

If a file has an object of apparently fairly small dimensions, it assumes the model was created in imperial units, rather than metric. It automatically scales it up by a factor of 25.4 to 1. You can scale it back down very easily. Look under the scaling pull down menu You will see a scaling factor o...

Re: Temperature error

Does it shows these temperatures while warming up. Earlier versions of software show negative temperatures once the print actually starts, but these are meaningless.

Re: Question about wiring - UP! Version 1.1

the power socket is for this filament supplier. the motorised filamentt supplier was discontinued some while ago as it was found that there was sufficient pull by the extrusion motor to "drag" filament from the spool. I kept mine going until recently, however I now do not use the filament supplier. ...

Re: UP Plus 2 fails to print solid vertical walls

I do wonder whether we will ever see software/firmware allowing walls of less than 1mm. I have just seen some results from a kit build 3D printer, the Velleman K8200. A kit for £699 from UK supplier. The print was of some 45 degree lattice work between 2 beams, the lattice cross pieces were 0.5mm in...

an easy way to measure the effect of the resistor change, if the exact values are unknown is as follows. with a cold intilasied up, without doing anything to turn on extruder or platform heaters, just open maintenance window, set your resistor switch to original unmodded position, now note the extru...

Re: Build platform heating element keeps burning

Vad,

If using acrylic you need a greater clearance from the nozzle so as to avoid he ABS "sealing" itself to the acrylic, try 4 sheets of paper, or more, thickness as a gap measuring thickness rather than the usual two.

You might alternatively try the cold acrylic plate solution.

perspex (acrylic) platform height

well it finally happened, my bed heater cable failed where it is most stressed as it bends. So I thought an ideal time to try the perspex cold bed solution, bought a 4mm sheet and tried printing (ABS). Sure enough ABS sticks well to the perspex, in fact a little too well. I normally set the platform...

Re: Printing stacked parts possible?

I guess if you try to stack parts by loading them into the software and then vertically offsetting them in the 3d window it will NOT work. the vertical shift function does not seem to work, I tried the opposite, to start a print part way through, vertically by offestting the item down into the platf...
