Re: No extrusion - etching on printer bed

The beds I have ran across with the PEI plastic 'etched' like that I have had to pull the old PEI and clean off the adhesive then reapplied a new sheet of PEI on the clean glass plate. The nozzle kind of puts the groove into the adhesive also while damaging the plastic sheet. So just replacing the P...

Re: Clogged Hexagon Hotend

Anyone have any tips on cleaning out the Hexagon Hotend? I've read the tip in the manual for removing the hotend but from other users saying that the threads are near impossible to realign, and with my nozzle being "welded" (not actually) to the hotend, i'm a little leery of taking it off. I attemp...

Re: Max stepper temperature

From the specs for the steppers:

they can run at 100 °C!

So they can and will run hot, but unless you are over-driving your printer they should be fine. Or you have it in a really hot enclosure, that will not allow sufficient cooling of the steppers.

Re: Aftermarket Parts (MINI)

The connectors on the Mini use a hard to source LCD panel(Do not know where the posting about this is located on the forum.), so no it will probably not work with that panel.

Re: Is there a solvent that dissolves Ninjaflex?

I asked a person I know that works for Fenner Drives and knows a lot about Nijaflex and he said nothing you would want to use. Only things are pretty nasty to use.

Re: Cura Caused Adhesion Issues

Eventually air bubbles could get trapped between the silicone heater and PEI... not sure if the Mini has glass sandwiched between... It doesn't look like it. Yes there is a glass plate between the heater and the PEI film. The few separated films I have seen were more white where it occurred, you ca...

Re: Taz 2.1 Lead Screw Update

Unfortunately, it has caused a new problem that actually didn't exist with the old threaded rod set up... Z wobble! It is very slight but it is visible on my parts. If I move the Z axis up or down, I can see the wobble in the X ends. Have any of you experienced this? Does this mean I have lead scre...

Re: Taz4

1. Is the fan in front of the control board spinning.

2. If you print from the SD card with the USB cable unplugged from the printer does it still hang printing.

3. if #2 is a yes contact support.

4. The bed heating times may be due to air currents hitting the bed surface and cooling it.

Re: replacement of green big gear

I have had to more often replace the small gear than the large gear. But they use ABS to print the parts as far as I have found out! :) I have taken one of their pre-'tweaked' gcode files for other parts and made myself a profile for Cura that uses the infill and speed settings they use in those fil...

Re: Hexagon Hot End Jamming with PLA?

It helps the starch bonds that can build up in the extruder slide past each other and not just continue to build. Thus relieving some filament binding issues that may occur. I use a filament oiler/cleaner if I start having PLA binding issues with filament while fixing printers.
