Printing issues ...
Re: RAMPS for Due! - 11 years ago
Quoteturutk Are there any news about this project? Bobc and Sublime got into a disagreement in another thread. From what I can tell, bobc took his ball and went home, removing references to RAMPS-FD from his forum signature. I had the funds put aside to buy a revised board as soon as they were available, but gave up over the weekend and spent the money on a non-Arduino package.....by vreihen - Controllers

QuoteMrDoctorDIV So what do I do when I want to go faster? I'm not building this printer to be slow.. Put a Micro-SD card into that silly little socket next to the USB connector containing the file that you want to print. Seriously, given the headaches that I and others have had with USB-based print jobs locking up mid-print, I can tell you why that card socket is there and can't stress enougby vreihen - Repetier

QuotebytemedwbThis is what I get for buying a 3rd party cheap clone since I cant find a web site or anything for the manufacturer. You must not have looked too hard, since the URL is silk-screened on both boards: http://learn.makerlab.me/guides/1/articles I will leave it up to you to translate from Chinese to English via Google or some other service. They even have online support forums. Coby vreihen - RAMPS Electronics

At about 14:15 UTC today, I tried to view reprap.org/wiki/Azteeg_X3. After a minute delay, I received a "502 Bad Gateway nginx/1.4.1" error. At 14:30 UTC, I tried to get to this thread to post the above info, but the site wasn't responsive. After a 3+ minute delay, I received a "504 Gateway Time-out nginx/1.4.1" error.

During the 6/18 outage (over 7 hours here in North America), Nginx was answering HTTP requests but indicated a caching problem after a minute delay trying to load the page. I don't know the exact architecture in use, but from my experience with Apache as a front-end cache to a back-end web server this is almost always a problem with the back-end server crashing or having database problems.

Your print temperature is way too high for PLA! Back it down to 185-195C, and the E3D will print PLA just fine.....by vreihen - Printing
Re: Prusa i3 Heated bed not up to 110 degree C - 11 years ago
Once it has reached 110C, it can maintain the temperature. Since heat radiates upward, insulating the top of the bed while it warms up works best for me.....by vreihen - Printing
Re: Prusa i3 Heated bed not up to 110 degree C - 11 years ago
Here's a source in Denmark: http://reprap.me/heatbed/iso200.html I do not have cork under my heatbed or use glue or any chemicals on my glass, and just place a magazine or newspaper on top of the glass as an additional insulator to speed up the bed heating process.....by vreihen - Printing

Re: 14" Silicone Heat Bed - 110v with Digital Controller/Display - 11 years ago
Can they produce the heater pad with two independent zones each rated for 110V? That way, our friends in the rest of the world where 240V is common can use the same pad, but with both 110V zones wired in series instead of parallel for 110V. (AC does work this way, correct?)

Re: Homing and axis movement issues. - 11 years ago
Unless you changed to relative positioning, G1 Z-10 tells your printer to push the nozzle 10mm through your bed (z = -10) which your printer cowardly refused to do. I'll give you a head start on what I had to learn the hard way. X=0, Y=0, Z=0 is the center of the print bed, with the nozzle touching the bed. The endstops go on top, and a home command should set X=0, Y=0, and Z=max_height afterby vreihen - Delta Machines
