Attempt to print the Digital Sundial in ABS on a Rostock Max V3. It started curling and detaching from the bed almost immediately. IMG_0968.jpg Presumably, after 5 mm, the curling was bad enough that a head strike shifted the belt on the Z tower by one tooth, so subsequent layers had a fixed offset....

I got a thermocouple and according to it, the thermistor is actually reading low. When I set the extruder temperature in the 200-220 range, and the thermistor says that it is at the target, the thermocouple is indicating 6 degrees hotter. So running the PLA at indicated 225 (which doesn't have any e...

I don't have a thermocouple. I guess that's my next tool to buy. (Any recommendations for a reasonably good cheap one?) If the thermistor were off by so much at 220 C, wouldn't you expect more than a few C in error at room temperature? My bed and nozzle read the same value to about half a C, and in ...

It kicks when not extruding. When I have the temperature at 210 (using Excelvan PLA labelled as 190-220 C) and the ezstruder motor is unpowered, I can turn the knob about half a turn before it it stops due to back force from the fillament. (When I let go it springs back quite a bit.) Pushing into th...

On my new from-kit Rostock Max V3, I am getting bad EZStruder kickback. This is where the EZstruder stepper and gears tries to push the PLA down the Bowden tube, and the motor suddenly jumps back about 30 degrees. (This is not a software commanded retraction in the GCode.) As a result, much less PLA...

Here is my 3DBenchy. MatterControl/MatterSlicer in PLA with all stock parameters.
And here is my third print, part of a CowTech 3D scanner. My H1.1 was never this good, reliable, or easy to use.

It didn't take 25 hours to print the cube. It took 25 hours of assembly etc. time to build the printer. Printing the cube took 30 minutes or so. I am using the slicer that Mattercontrol bundles, which I guess is matterslicer. I haven't looked at all of the parameters yet. I haven't found the retract...

Calibration brick: 20.10 x 20.07 x 9.90. The power supply fan is LOUD. Much louder than it should be. One other tool I forgot to mention: a spudger is a plastic (or wood) stick. Makes it a lot easier to peel backing paper off the plastic parts. You don't have to worry about getting your fingernail u...

Printing the calibration brick that comes with matterControl, on unadorned glass, standard settings on the standard slicer. SImulating the the stock experience for a first time printer.

Build time to first print: 25 hours[\b].

I like.

Calibrated (30 minutes)

I have MacOS Sierra and I had to update to the latest Arduino software. No problems.

Video of calibration recorded, but it looks just like mhackney's.

Completed assembly(1 hour)

I couldn't get the spool holder fully installed into the slots on top on one side..

When I move the carriages, lights turn on, indicating that the stepper motors are connected and generating power.

I am now ready to flash the processor.

Looking good!

I didn't order any Fablam. Should I try just printing directly to the glass (with PLA or ABS+, at what recommended settings?), or should I lay down some 3M blue printer's tape first?

More final assembly (2 more hours, plus time to ask questions and update the Dozuki and build log a bit) Wiring installed and ready. Belts threaded, clamped and tensioned. (I am impressed by the belt mechanism and the ease of control over tension.) In Part 1 step 34, it says to install the 2-pin he...

Hotbed wiring is not in the "Wiring the RAMBo" video for part 3 step 10. (And it couldn't be there because the top assembly isn't installed yet.)

It is in the hotend whip video. The answer is that the hot bed thermister goes to Thermistor2 (not 1)

What is this piece? It is in the bag with the belt clamps.

The instructions don't include hooking up the hot bed. (Thermister to Thermister1 on RAMBO, black wire to Heat2Bed on RAMBO via screw terminal block.)

Is that correct?

I have added that step to the dozuki.

Final assembly (5 hours so far) Cheapskate carriages Vice grips (or bench vice) and coins to squeeze the two sides of the bushings to each bearing. I'm going to call the armature that holds two bearings and allows them to pivot a 'dihedral' to emphasize the angle it has. Always be aware of its angl...

Rambo and wires (2 hours) Endstop switches: Connect to the two prongs that you bent outward earlier. The video says to use the 'outer terminals of the switch', so I connected to the terminals that were closest to the outside of the Rostock. Instead you want the two terminals that are closest to the...

4 years ago I built an H1.1 . Now I am working on an Rostock Max V3. I am currently about 14.5 hours in and have mounted the top motors. This is probably a reasonable rate to shoot for by people with limited mechanical skills. If you're mhackney you are probably asking why I needed to build 3 of the...

(On Repeater Host, at least, in my experience with an H1.1, but it should transfer.) You can hit the pause button, then use the movement controls to move the head, do something, use the controls to move back (i.e. you hit the X+100 button once, do what you want to do, then hit the X-100 button once)...

Thanks for all the advice! I just placed my order. The Rostock has everything I want. Except for a dual extruder. And feedback on the extruder and the carriages. And computer-vision based monitoring. And non-planar slicing. And optical-type resolution over a meter-class build volume. And biological ...

In the past few years, 3d printing has moved from people who wanted to fiddle with a 3d printer to people who want to 3d print things. About 4 years ago, I built a SeeMeCNC H1.1 kit. It took me about 50 hours. The build log is at http://forum.seemecnc.com/viewtopic.php?f=42&t=928&p=11401&...

Is there anywhere I can find the current firmware for my Rambo Board? I'll admit that I am pretty new at these things, but I went through all the information I could find about the Repetier Firmware at https://github.com/repetier/Repetier-Firmware and I'm totally confused about how to actually conf...

I was wondering if you could fill me in just a bit on how you wired your RAMBo? I realize I should know better, but I simply have no idea how to read the fancy-pants electronics diagrams that I have run across describing how to wire the RAMBo. Specifically, the power supply that comes with the H1 i...

There's half an inch or more under my screws. Here's a detail shot. zaxis_detail.JPG Note: 1) The platform sits above the bar clamps. Note the orientation and the order of the bar clamps and the bars they clamp. 2) I have the feet attached which gives it more ground clearance. 3) There are two 'fini...
