There is a downside to a bigger bed, which is particularly evident if you print ABS. That is, it takes a long time for the bed heater to bring the bed temp up to the 110C or so you will want for...

One of the main advantages to locating the MOSFET PCB on or near the heater PCB is that you could use the light gauge OEM wires for a very short run from the heater to your new PCB. This would avoid...

How about this one instead? Says it is for close work and does not have the M extender.

I'll admit to not having thought this all the way through, but .....

Can you arrange the new PCB in a way that would permit using conductive epoxy to bond the new PCB to the heater PCB? If the...

I think you are kidding, but I am happy to upload "glasswrecker.stl" to thingiverse if you want it ;-) To get full effect, though, be sure and slice it with 5 layers at the base.

Ambient temp is between 18C and 20C, so not too bad.

The piece is a terrain model of one of the peaks in Rocky Mountain National park (Mt. Ypsilon). I am having some fun printing little stocking...

I finished my build recently. I will pass along some wisdom that was gained the hard way ;-)

1. My kit included 2 X-idler brackets. One of them was the old style. The second one was the new...

Check the settings in slic3r (or whatever slicing software you are using). Dropping the bed temp to 70C after the first layer, in my experience, will cause ABS prints to lift 100% of the time.

Very nice solution.

This is the object that pulled the divot off of the glass.

Another perspective on the divot.

I think the primary cause of the...

I have the 0.4 Hexagon for 3mm filament. I chose the hexagon because I plan to print with nylon at some point. I wanted the ability to print PLA, too, so that ruled out the Magma.

When I told...

I have the nominal 1/8" borosilicate/pyrex plate installed and have done a few test prints. First observation is that the boro is a full 1 mm thicker than the window glass (3.2 mm vs 2.2 mm). It...

According to the spec sheet for the Omron G8QN, the electrical contacts are rated for at least 100,000 operations. Assuming around a 5 second time base for the PID routine*, then the relay would be...

I have an expensive piece of borosilicate glass that I am keeping in reserve, until I "know what I am doing." I wonder if the borosilicate also will be prone to this kind of damage?

Perhaps others have seen this: my most recent ABS print pulled a small divot (6mm x 6mm x 0.4mm thick) of glass off of my build plate! The divot remained stuck very tightly to the underside of the...

The AC SSR's I use for controlling nichrome heaters drop around 0.6V across the switched terminals when conducting. They are spec'ed at around 1.6V drop, but in my applications I only see around...

Now, there's an idea ....

I am still experimenting with PLA vs ABS. ABS is opaque, while PLA is somewhat translucent. Depends on amount of dye, I guess. PLA permits a lower bed temperature, but for some objects (I am...

I use a thin coat of Elmers All Purpose Glue Stick on the bed. Wet a paper towel and apply some of the stick to the wet towel. Then apply some glue directly to the glass. Swish the wet towel...

That seems to have also ended my squeaking. Thanks.

Jim

Thanks for the link. Very informative thread.

My creak is different from the noise I heard on the posted video. Mine is more like a rusty hinge.

My present working theories are 1) the sound...

Squeak is reduced, but still present at times with PLA. No squeak with ABS. In the previous thread, did you come to a conclusion as to the cause of the squeaking?

Recently experienced 2 more...

Glass is actually not quite as bad a thermal conductor as I thought. While metals like copper are hundreds of times more conductive, glass is more conductive than water, wood, and even salmon :D

Makes me wonder how much more effective, if any, a mirrored surface might be? I like the idea of clips on all 4 sides. Think I will give that a try.

Thanks.

I ended up at 880.

My factory default was 841, but this extruded a little less than 100mm in my calibration test.
