Re: Hictop beginning - question about ink spilling and more - 8 years ago

What do you mean by "ink?" Also, when you first assemble a hot end, you have to heat it up to near its top operating temperature (so for a Mk. 8, around 230C) and torque the nozzle into the heat block. As it heats up, it loosens up. E3D has great instructions for asssembly of their hot ends, and other assemblies such as the Mk. 8 have a similar procedure. 2. On my printer, I set the end stop

Re: Kossel - Printer ignores commands, motors don't move - 8 years ago

A few things I would try: You say you use the "home all axes" button in Pronterface's control panel. How does the printer respond if you send it G28 via the console? Does the machine move when clicking the motion buttons in Pronterface? Have you tried using absolute positioning (G90) rather than relative positioning (G91)? If you have a controller display, does it work with M117 commands? W

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

You know what? I slapped together a Folger Kossel, input the length of my diagonal rods, and it printed a couple decent parts. If I can get it running true of the bed, I think I'm in fine shape.

Re: Auto level doesn't seem to auto level - 8 years ago

I'm afraid neither suggestions are ultimately helpful. One thing I'm going to try is shimming the diag. rods. The rods are about 51.7mm apart outside to outside at the effector end, and 51.1mm apart at the carriage end. I'm placing an M3 washer under each carriage rod end to bring them into parallel. I've read somewhere that this will reduce effector tilt.

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

dc42, what in your mind is the difference between "auto calibration" and "auto level?" I've got the stock inductive sensor, and the offset is 31mm. When the machine is doing the bed probe routine, in the bottom right corner (quadrant 4, +x -y) the nozzle actually taps the bed surface, so I wonder if it's just that the sensor is crap.

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

So what the hell is up with the auto level "feature?" It doesn't do a damn thing! Call G29, it goes through a big song and dance moving the head around, but it doesn't actually compensate for anything, the print comes out as if it hasn't adjusted for anything. Lots of people seem to have this problem, but no solutions. I'm running the firmware I got from Folger. I found some other Kossel fir

Auto level doesn't seem to auto level - 8 years ago

So I've got my Delta (Folgertech Kossel) up and running, but the auto level feature doesn't seem to achieve much. It runs the probing sequence, but it doesn't seem to do anything with the information. The print starts and the bottom layer is off. One corner of the print is low, one is high, like the bed isn't level. Is there anything to do to the printer besides put the G29 command in the sta

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

This isn't a particularly good place to put this, but I'll put it here anyway: the firmware makes me nervous. Not that I think Marlin is out to get me or anything, it's just that I find it a little incomprehensible. What gets me is I'll download the firmware from Github and it will NEVER compile without throwing some cryptic error. No two versions are exactly alike, and if something goes wron

Re: Removing old filament - 8 years ago

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

Mostly I just need the RAMPS/bed mount. I'll probably 3D print some end stop mounts. I have a bit of a prejudice against using wood in the frame of a 3D printer. Acrylic isn't exactly ideal either, but it has the benefit of being humidity proof, and I can still cut it on my makerspace's laser. I'm going to use Tech2C's compact bowden extruder, which is its own mount, there are dozens of ways

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

It may be that different industries use terms slightly differently. My aviation background associates threads which are heated, assembled and allowed to cool to lock them into place with the phrase "interference fit." Whatever we choose to call it, the physics are there. The Aluminum heat block expands with temperature more than the steel heat break or brass/steel nozzle, so the threads loosen

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 8 years ago

@sharkicicles, no, the plastic didn't jam your threads. It's called an interference fit. As the nozzle got hot and cold, the threads tighten. If you have to disassemble a hot end, heat it to printing temperature before applying torque. Once the threads are broken loose, then cool the hot end and unscrew. Grip the hot block, not the cold end or heat sink. I'm just starting to build a Kossel,

Quotejabu32 How do I get rid of the waves in the outside layers? Looks like your extruder driver current is a little high. Check the Vref. You probably want to reduce the current on all of the steppers, they tend to run a little hot.

Re: Plywood frame problem - 8 years ago

I haven't encountered that problem as my frame is metal, but I can see your dilemma. You may have to contact the manufacturer of the kit and request a correct replacement. The Prusa frame plate is just too big for my laser cutter, so I can't make you a new one.

End stop trigger questions - 8 years ago

So I'm preparing for an auto bed leveling sensor to replace my Z axis end stop. Right now, with no modifications, I'm using the M119 command to see which end stops are triggered. When none are touched, they all read OPEN. With the Y and Z axes, when the switches are depressed, both minimum and maximum end stop values read TRIGGERED. The printer seems to behave correctly, so it hasn't been a p

Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 8 years ago

So the display works when the USB cable is plugged into your laptop, but not when unplugged. I bet the 5v regulator on your board has gone. I know I harp on that a lot, but it's been a BIG issue with me, and if you do ANYTHING wrong with the machine, that regulator will let the smoke out. There are three ways to power an Arduino: You can put up to 5.5V on the 5V pin (basically don't do that.

Re: Aussie keen to join the 3D printing party! Leaning to Prusa i3. Advice please - 8 years ago

If I were you, with such a budget, I'd go with a genuine Prusa branded i3. That's if you're really set on an i3 type. Your budget would allow you to buy a CoreXY machine, slightly more complex in rigging but they tend to go better and faster.

Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 8 years ago

It's good to have spare electronics. I ended up repairing my FT Arduino with a new regulator, and I use it as intended--as a workbench playtoy and tryer outer. The chips on board are genuine Atmel AVRs, so for most uses they're fine. Running a 3D printer is demanding on the regulator, and these weren't up to snuff. I have yet another set of electronics laying around ready to be swapped out.

Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 8 years ago

I recently had a problem where the cooling fan on a printer (not my personal one, I haven't installed one yet) cooled the nozzle too much when it turned on. Make sure that's not happening. Also, about OctoPrint--I've downloaded the OctoPi image, and can't get it to work. I mean, at all. Downloaded the image from GitHub, burned the image to an SD card, plugged into the Pi, and it acts like the

Re: About that print quality - 8 years ago

Hang on, did you say you've got a .2mm nozzle, and you're printing with .2 or .3mm layer height? That's an issue. layer height should be less than 80% of the nozzle diameter at maximum. The following was printed on my Folger, with the stock .4mm extruder nozzle, at .1mm layer height: Notice how tight the layers are, none of those gaps. That's what you're shooting for.
