Need bed for Taz 4 expansion project

I have Taz 4 that I am planning to double the Y axis on. I am looking for a supplier for the borosilicate bed. Does anyone know where a 600mm x 300mm sheet can be found? Thanks, Greg.

Re: Trouble with upper layers - hardware related?

Make sure you are using the right nozzle diameter for the profile you're using. Also, make sure the nozzle is not partially plugged.

Re: Lulzbot silicone bed... defective?

Check the heater with an ohm meter, it should read around 2.4 ohms. If it is drastically different then I would suspect it is bad. Make sure you check it when the bed is unplugged.

Re: Lulzbot Mini temperature dropping to zero when printing

What software are you using to print? Try slicing with another slicer or at least a different profile. Look in the gcode and see if that is setting temp to 0. Also, unless you are printing somewhere the ambient temp is 0, then it shouldn't see 0. It does sound weird.

Re: Any way to speed it up?

If you're printing mechanical parts, try going to a bigger nozzle. The jump from .35 with a .2 layer height to a .5 nozzle with .3 layer height seriously lowered print time.

Re: Taz 6 X-Y calibration difficulty

The difference from one machine to another could be a few different things. The steps per inch of an x or y axis shouldn't be an issue because the steps per revolution of a motor and the number of teeth on its gear are the same. This small difference you show could easily be due to differences in ex...

Re: hardware malfunction

You need a new idler arm, if you can get the machine printing you can print one. If your extruder is ABS you can temporarily repair the broken part by solvent welding with acetone. Cyanoacrylate glue is another option, either should work well more than is needed to print the new part. What model of ...

Re: Taz extended bed heater options

OK, so my next question is does the Rambo limit the current when it gets near temp, or is it a pulse-width scenario? I'm guessing because it is controlled by a mosfet it pulse-width of sorts, and that is why only an SSR is needed. Also, is silicone rubber designed for mold making appropriate for the...

Re: Is this heat creep? (TAZ 5)

That sure looks like heat creep. Make sure the micro blower is working constantly and is pointed directly at the fins. Also keep an eye on your nozzle temps, a failed thermistor could cause nozzle overheating to a point it overwhelms the micro blower.
