Re: My N2 won't print anymore

I cleaned the nozzle, replaced the nozzle with a brand new one (0.4mm, all the same size), tried different filament brands (some brand new) but no luck. The odd thing is that after I clean/replace the nozzle, I load the filament at 240-250° and it extrudes perfectly fine in a straight line. I have ...

Re: Turn Off Left Extruder

Still having an issue with the filament not loading or jamming which then causes the hobbed gear roller chewing a notch into the filament. I am not an E2 owner, however, I just saw and read things knowing how the E2 works that made me cringe. Here's my take. We saw a somewhat similar issue on the o...

And, Being user Zemlin just posted about using BL-touch, you might ask him for recent pointers and how he did it?

Re: Issues Printing With TPU

I cannot stress enough, at best, if you do no modifications, this is the mitigations you can apply. #1 print slower. This feeds the filament slower, making less back pressure at the nozzle, also allowing the rubbery filament to slide down the walls of filament path between the feeder and the hotend....

Re: Bltouch on Raise3d

You can use it how you want but- a tip I found on my big printer- keep your physical limit switch and wire it into the motion board as an "Oh poop" switch. It is possible for scenarios of a BL-touch to fail (example, not over the bed, bracket bent or melted, wiring failure, etc). You CAN a...

Re: Bottom Surface Flowrate

Earlier on, you asked a good question, so lets see if I can try to answer that one. How the slicer creates gcode- not the way you worded the question but what you basically asked. You give the slicer the following variables Layer height (basically nozzle to previous layer or nozzle to bed gap for fi...

Right here is where you've gone wrong. You aren't following the "I changed something major (nozzle size), and gone back to basics tuning my slicer and printer for the new nozzle". The first thing to do when you have a suspected calibration problem is go back to the basics- extrusion volume...

Re: Bottom Surface Flowrate

Here's a thought: if you install a larger nozzle- first layer nozzle homed gap might need to be higher..... Next, I reread the post and saw this: You can see that the individual lines of filament are not squishing together to form a somewhere-near-flat surface. Extrusion width is currently set at 1....

Re: Bottom Surface Flowrate

See the gaps between your infill lines on the top of the part AKA screen door effect? There are basically 2 functions that affect that. Extrusion width sets the distance between adjacent paths based on an assumed squished width the plastic will achieve- obviously that's not as wide as expected. OR E...

Re: Molex connector? Need to replace heat bed connectors.

Both correct. Be sure to replace BOTH sides of the connector. NEVER reuse the pins if the connector failed- they will cause the new connector to fail. I see you are possibly replacing the entire bed heater and so that comes with the male header. Yes, thermal runaway is defined in firmware as a failu...

Why they might fail taken right from the manufacturer http://www.jst-mfg.com/product/pdf/eng/eVH.pdf #1 Operating conditions might exceed maximum rating of 85C • Temperature range: -25°C to +85°C (including temperature rise in applying electrical current) #2 Aging from use and environment • Contact ...

Re: Molex connector? Need to replace heat bed connectors.

So in your case, if the heated bed is failing (probably from printing a lot of ABS but could fail just from normal wear and tear), then opposite, you should be checking the extruder breakout connector. If one is failing, the other might go bad in short order.

Re: Molex connector? Need to replace heat bed connectors.

I seem to remember both answering the connector question and telling users they probably should be checking their heated beds for the same potential failure given the age of the printers. https://forum.raise3d.com/viewtopic.php?f=17&t=20456 They are JST VH series https://www.jst-mfg.com/product/...

I would like to see the ability to have both skirt and brim in the drop down menu. Currently, you can have skirt only or brim only, but not both. Should be easy to program in. Not sure why it's missing. Somehow, I don't get it. Brim is skirt that attaches to the model. Conversely, skirt is a brim t...
