Re: Missing temperature offset correction

Aerospace testing being the upper end and @home being the low end, a happy medium that is convincing enough for Raise3D to even consider their design is flawed is what I think you're after. Our difference of opinion is based on making a public request, (The manufacturer is hereby requested to remedy...

Re: Missing temperature offset correction

I believe if you were to run a CAD-based thermal model, (before & after your cooling modifications, using aftermarket and stock nozzles from Raise3D) through a simulation, you would see a difference. Follow that with a current / load test to determine how the electronics is operating and the dat...

Re: Missing temperature offset correction

As a test engineer, I have seen data manipulated to satisfy pre-conceived outcomes. Where I work, we strive to analyze analyze test data objectively using as many data points as is practical before establishing performance criteria. This test appears to be something a technician would produce (simpl...

Re: Left Extruder jams

There is nothing to disassemble. The printed part snaps into place and is secured by two tie wraps that slip through the holes in the part.

Re: Left Extruder jams

Your Google translate is not meaningful. Do you mean to say: I printed this part but cannot install it? (The second sentence is not clear.) This is a very close-tolerance fitting part. The close tolerance is what makes it work so well at minimizing movement of the cabling. It snaps into place with a...

Re: Printer Saver

While software-based machine vision is useful, real-time feedback via current sensing to stop the gantry would be more proactive. Imagine a nozzle/hot end slowly loosening and beginning to bury itself into a sheet of Buildtak, (I've had this occur twice and seen many other examples posted.) - how lo...

Re: Printer Saver

This would appear to be a very easy-to-implement firmware addition to a future motor controller board upgrade that would result in added protection at minimal cost, plus bragging rights for their advertising. I don't know if their competitors offer a similar protection feature, but it would be an in...

Printer Saver

If you've spent much time in this (or any 3D printer-related site) you have probably seen posted photos of printing disasters. (I've posted my own here someplace.) Many contain gouge marks in the print bed, or molten piles of plastic that have cooled on the outer edges and trapped the heated printhe...

Re: Raise3D Pro2 Clicking, Stops Extruding, Cold-Side Clogs

Another related question aimed at Raise3D: I've seen the YouTube video tour of Raise3D's LA operation, which makes videos, (much more clear than the written procedures originating in China) distributes printers throughout the US, and qualifies filament. https://www.youtube.com/watch?v=2f90Eg-TcXo Wh...

Re: Raise3D Pro2 Clicking, Stops Extruding, Cold-Side Clogs

I think a more compelling argument may be made by asking the community for successful examples of >18-hour, high-temp filaments (ABS, etc.) printed with a (stock) Pro2 series - or an E2 model for that matter. My next printer HAS to be able to print ABS and ASA for 18-36 hours at a time. An owner sho...

Re: Awful Layer Offset Mid-Print

I might not hurt to visually inspect the X axis motor coupler to ensure it hasn't sheared. It only takes a few minutes using a Phillips head screwdriver to remove the clear acrylic panels. Once you gain access to be able to see it, move the print head by and and inspect the coupling.

Re: ideaMaker 4.0.0-Beta Release Notes

Neither is blurry. The new lighting scheme offers more illumination to the interior walls. The "old" view has harder shadows, which increases the contrast of the smaller edges. These appear to be fixed lights. You can change the object's orientation to improve the overall view. Note the co...

Re: Supports removed during preview

This may be irrelevant, (without viewing the model) but have you tried slicing the model after being rotated 180 degrees so the larger box is on the bottom, removing the need to print overhang supports?

Re: Temperature sensor error

Your post is confusing. You state the thermocouple was bent and kinked. --Do you mean the thermocouple wiring or thermocouple itself? Bent/kinked wires do not inhibit electrical current/signals. Broken conductors and intermittent connections do. You wrote the printer has been running fine, followed ...

Re: USB to Pro2

I do the majority of my printing via USB memory stick. As soon my print is loaded and the printer begins moving the bed in Z, I pull the memory stick and head off to do other things - like getting my next print(s) sliced and transferred to the USB stick.

Just remember, the leveling adjustment screw is positioned to interact with the optical sensor for the Z axis. You have to press the Z-axis Home icon to move the bed after each thumbscrew adjustment. Homing the bed plate Z-axis position relative to the (left extruder nozzle) takes only a couple of m...

Where is the printer located? Tanganyika? Bora Bora? These aren't cheap to ship, regardless of condition.
