When you performed the Delta calibration, did you also calibrate the extruder's steps per mm? Check the hotend thermistor setting to verify that your temperatures are close to what the firmware is reading? I cannot see any of the details in your printed object, but it appears to be an over-extruded blob that may have started out as a test cube. Another thing that you might want to verify is th

This sounds like the OP broke his E3D-clone's stainless steel heat break (the heart of the E3D), and tried to cobble a replacement part together out of glass. If so, there's no point in trying to troubleshoot the jamming until the original stainless steel heat break has been replaced with an exact stainless replica...inside and outside. If the cold end of the cooling fins are hitting 60C with P

I am 50 and always worked in fractions and decimals. Since I got into 3D printing I am learning metric and I really, really wish the U.S. had switched over to metric like they said they were going to when I was in grade school.
I'm in the same age group, and had the good fortune of living near the Canadian border in the 1970's for grade school. Half of our TV came from Toronto, an

The reason for using metric is because Intel has never produced a CPU chip with a floating-DENOMINATOR fraction co-processor. Well, unless you count the early Pentium chips that thought nine squared was 81.000001.
Get with the program. Even Americans use metric.....

Another suggestion to make an improvement on the current status quo. I don't know how much a couple thermocouple interface chips cost, but having them on-board might drive the adoption of that superior technology over time. The reason why I bought my Megatronics 2.0 board when I started was because it had two thermocouple inputs and no other board had the option.....

My £0.013 (two cents USD) is that to keep the cost down for use as a 32-bit board for the masses, it needs on-board, ribbon cable header-compatible support for the two common LCD drivers from the RAMPS platform, namely the LCD-2004 and the RRD GLCD-12864. No piggyback boards for this feature. This is purely because these boards are so common that the pricing is low, not because they are the bes

I bought a 600 watt, 24V power supply (Mean Well SP-600-24), and switch the bed using an external SSR with a heat sink. To power everything else, I am using a 10A, 24V->12V step down buck converter to make 12V. The price tag was not cheap ($120 USD), but you can't put a price on a 6-minute heated bed warmup. You can probably get away with a much smaller 24V supply, but I wanted some extra c

Every spool of ABS filament should come from the manufacturer with a 24V power supply for the heated bed. From my own experience and the number of threads popping up in the past month with other people going through the same struggles trying to get a heated bed to reach/hold 110C to print ABS, a lot of people have this same complaint. My 300mm diameter Onyx heated bed would not reach 100C after

From personal experience, I will say that *any* minor inaccuracies of the probe repeatability will negatively impact auto tuning. I consider it a gimmick now, and always do my calibrations manually. There are several guides out there, and even Jay's (?) video tutorial on YouTube. Seriously, with just a little practice, you can do the job quicker manually using the gray matter between your ears

Can it be that there is some kind of buffer issue if you print too fast? It seems that my printer can follow quite well, but still it blocks every once in a while (= a few times per layer) for about 100-400msec or so. It seems to wait for a commands from the PC.
Maybe something to do with the baudrate (set to 250000)?

What do you have the filament diameter set for in Slic3r? Does having Slic3r believing it is using 3.00mm filament when it is really printing 1.75mm filament cause this type of under-extrusion problem? Did you calibrate the steps/mm on your extruder by measuring how far the filament moves?????

Instead of waiting for the absence of adult supervision, put your heatbed to work while you're testing it. Put the spool in the center of your heatbed, and cover it with a small cardboard box.

Use your current heatbed, a small cardboard box, and a printed "MakerBot" logo in PLA (or some other suitable scrap PLA part). Place the part over the thermistor on your heatbed, with something metal underneath it to induce droop when it gets too hot. Put the box over the part as a heat retainer. Turn on the heatbed to 50C. Bake for 30 minutes. Repeat by increasing the temperature 5C until i

According to the spec sheet link you posted above, the heatbed should be drawing 17A when cold. You can measure the actual resistance across the terminals of the cold heatbed, and use Ohm's law to see how many amps your exact heatbed should be drawing at your measured input voltage. It may be that your heatbed has too high of a resistance. There are several posts for how to do this and interpr
