Re: Build plate height differences

use the M206 on all printers Haven't a clue. I measured the height of a cube a long time ago, tweaked the initial Z offset with M206 to make the answer come out right, and it's been working fine ever since. The platform in my M2 is fixed in place and Nothing Changes from print to print, so maybe I'...

Re: Build plate height differences

center .04mm too close and most of bed .04 too far away Absolutely: split the difference! If you're printing 0.20 mm layers, then the first-layer variation is a survivable 0.16 to 0.24 mm. However, if you're trying for 0.10 mm layers, then the variation is 0.06 to 0.14 mm and you may have trouble. ...

Re: Quick Stepper motor questions

X-axis motor is a little squeaky Most likely, it's the pulley on the other end of the axis. There have been several versions (IIRC), but a dot of oil on the top of the central shaft won't do any harm to any of 'em and should solve the problem as it flows down into the joint. add (a dampener) to the...

Re: Layers are shifting all over the place

a few more things to confirm I was an idiot Those are the absolute best problems to have: they leave no doubt about cause-and-effect. A bit rough on the ego, though. In the future, someone we'll never know will have that exact problem, find and read this thread, look over at the printer, and never,...

Re: Layers are shifting all over the place

consistent prints for about 2 years Which says now's a good time for lubrication, pulley screw centering / retightening, and all the general preventive maintenance we tend to ignore while it's working. Judging from the model, though, the nozzle is whacking on raised perimeter threads after the part...

Re: Extrude stops extruding (not jammed), consistent temp issues (m2)

are we talking about the hbp or the hot end heating issue? I'm not sure anymore ... [sigh] The initial "above that it would barely extrude" suggests an extruder problem. The "extruder was getting overworked by retracting and extruding" could point to a filament drive problem. The "happening on all ...

Re: Extrude stops extruding (not jammed), consistent temp issues (m2)

Assuming the new thermistor is good, the failure will be in the cable between the thermistor and the RAMBo board. That's uncommon, but not rare. With the hot end at operating temperature, wiggle-n-jiggle the entire length of the cable to locate the problem; when the temperature fluctuates, you've fo...

Re: I bought a replacement thermistor for the v4 hotend...it's WAY too small!

looking for the heating cartridge Look on the bright side: you're now a member of the select group of M2 owners with a spare thermistor on the shelf, ready to install, when you need one. And, believe this, you will need one! And, should any of your pet mosquitoes get chilly, it can produce a very s...

Re: Extrude stops extruding (not jammed), consistent temp issues

the cartridge has difficulty maintaining a consistent temperature The hot end thermistor is failing, so order a new thermistor (*) and install it. While awaiting the package, restore all the settings to their previous values. There's no way to tweak around broken hardware. It's that simple ... (*) ...

Re: M2 octoprint on Pi what to buy

why not use a monitor mouse and key board on the PI for local access This is the part I don't understand about gearing up an OctoPi (or any Pi, for that matter). By the time you wire a Pi (*) to a monitor, mouse, keyboard, and power supply, then print a case and arrange everything, you've built a r...
