Re: ABS benchy issues - 7 Jahre zuvor

"perimeter print speed of 40 mm/s external perimeters at 64 mm/s" I'm pretty sure this is quite unusual. I didn't change lots of my Sl1c3r settings, but my perimeters are printed at 60, and my external perimeters at 30 mm/s. In Cura I set 60mm/s inner, 40mm/s outer perimeters. Try to swap those speeds, the outer perimeters usually get printed somewhat slower to improve surface quality.

Yes, looks like a bad wire. I had a similar issue with my extruder, and I found out that one of the cables was almost broken, giving a bad connection during extruder acceleration.

Re: Question about what I need to provide before I ask my question - 7 Jahre zuvor

I don't have any experience with PLA, so I usually skip PLA issues when it comes to speed & temperature. But from everything I've read, you absolutely need a part cooling fan when printing PLA. And regarding your previous questions about your i3: I can't find any of these, can you pls provide some links?

Re: ABS infill issue - 7 Jahre zuvor

I can't print at the moment. I did yesterday, and I noticed hotend temp issues. I print ABS at 240, and my temp varies from 239 to 240.5. Yesterday it jumped up & down, about 20-30 degrees. And it jumped so fast, I assume a loose contact to the temperature sensor. Usually the temp doesn't fall or rise 20 degrees in less than a second. Anyway the printed parts came out quite well.

Re: ABS infill issue - 7 Jahre zuvor

The gaps between the perimeters and the infill may be closed if you increase the infill overlap. You may try to print the same thing but slice it with Cura. For some things, especially holes and structures like this, Cura gives better results. Or try the new Prusa Sl1c3r. At the bottom layer you can't tell if it is over extrusion or a bed distance issue. My first layer sometimes look similar, pro

Re: RepRap Mendel wont respond to slicers. - 7 Jahre zuvor

If you have Repetier Server running, and it is connected to the printer, your other programs (like Pronterface, Repetier Host etc.) need to connect to Repetier Server, NOT the printer itself. If you disconnect or shut down Repetier Server, you should be able to connect to your printer with Pronterface, Repetier Host etc.

I didn't use Repetier Server, so I don't know it, but you need to stop the Repetier Server before you try to connect with Repetier Host or anything else. You probably know this already, but I just want to be sure.

Good you solved it. Anyway, if the LED went out when the bed had 27 degrees, and the bed was still heating up, you probably watched the wrong LED.

Re: RepRap Mendel wont respond to slicers. - 7 Jahre zuvor

If you get access denied it's most commonly some other software still accessing the port. You can't connect two programs at the same time. Check if any of your software, like Ardunio IDE, Pronterface, Repetier host or similar is still running.

Re: Problems with printer hot bed not being consistent - 7 Jahre zuvor

3.8 Ohm is a reasonable value for the bed, this seems to be good. These nasty polyfuses do behave very strange sometimes, but it doesn't sound like a polyfuse problem. Is your bed loosing the voltage and stops heating, or is your RAMPS shutting down the heater for any reason? In your test print logfiles from May 7 I can see the bed temp is set to 70 deg, then reaches 69.something, and then drops

Re: ABS infill issue - 7 Jahre zuvor

Ghosting or ringing is when the Y carriage makes a "hard" change of movement, f.ex. if you print a box, or you have a wall in x direction and there are some vertical things like holes, letters or similar. The carriage swings a bit, and you get an echo of the movement beside the structure. Goggle for "3d print ringing", you'll see what it is. Hundreds of pictures. In Sl1c3r there are extra bridgi

Re: Problems with printer hot bed not being consistent - 7 Jahre zuvor

0.00 is indeed a very low value. I almost can't believe this is true. Normally the measuring lines itself will have some 0.02 or 0.1 Ohm resistance. Do you have any chance to check if your multimeter may be broken? You got a spare 12V light bulb, maybe for the car or some halogen room light? Or check your extruder heating? A 40W 12V heating cartridge should have about 3-4 Ohm.

Re: ABS infill issue - 7 Jahre zuvor

I never printed PLA, so I'm unsure why you can print 0.4mm extr width with a 0.4mm nozzle and the parts are good. Maybe it's because PLA is more like rubber when hot, ABS is more like honey, less flexible. When you press hot plastic through a 0.4mm hole, the extruded line is cylindric, and a bit thicker than 0.4mm - it depends on the material, the surface tension (Oberflächenspannung), on the tem

Re: Problems with printer hot bed not being consistent - 7 Jahre zuvor

This littel thing will do perfect for this. Just turn it to the left 2 more, so it points at 200 Ohm (this is the Greek Omega, the upside "U"). When you connect the test wires directly it should read 0 or a very small number. If you connect your bed to them the number sould be somewhere in the range 1.2 to 3.something, probably. If you have less than 1.0 or more than 5, the wire or the bed is pro

Re: ABS infill issue - 7 Jahre zuvor

0.4mm nozzle diameter is the hot plastic coming out of the extruder. The printer will squeeze this onto the bed or the lower layers, so the actual extrusion width is larger than the nozzle diameter. Some smart people made some formular to get the smallest possible extrusion width, but it's definitely wider than the nozzle. So extracting 0.4mm with a 0.4mm nozzle will surely not work. The extrusio

Re: Problems with printer hot bed not being consistent - 7 Jahre zuvor

Yes, a broken wire to the heated bed can cause similar problems. At the beginning the bed may be ok, starting to heat. During the print, while the bed is shaking, the wire may loose contact, and the bed will stop heating. With a multimeter you can check your bed - disconnect the wires, and check the R with your multimeter. A 12V or 24V bed would have a few Ohms, a mains power bed will have more -

Re: ABS infill issue - 7 Jahre zuvor

Yes, good hint. I took h4nc's settings and set nozzle diameter to 0.5mm (because my nozzle is 0.5mm), forgot to mention this. Your PLA prints look good, so maybe you may lower the extruder temp by some degrees and increase the infill speed when pinting ABS.

Re: Reason for different surface quality on the same print - 7 Jahre zuvor

Leaky nozzle, I think. Looks like some of my prints. When moving without extraction, my head spits a bit hot plastic, and this is missing when extrusion starts again. I see little holes in your print right after movement, and the "overextraction" signs are visible where movement happens or stops, I assume. With my extruder I couldn't get rid of this completely, no matter what retraction settings

Re: Problems with printer hot bed not being consistent - 7 Jahre zuvor

It may be a bad PID setting. Did you save your old PID values anywhere before flashing new firmware? Wrong PID values may cause heating taking ages or not reaching the target at all, and a mix of both - especially when combined with some fresh air from an open window. Maybe you should save or write dowm your PID values and try auto tuning.
