Re: Can anyone identify this problem?

struggling to get the quality I was seeing before If you're using a stainless nozzle, then you're likely printing hard-to-use plastics: make sure the basics are correct before doing anything else. Reset the initial Z offset to "pretty close", calibrate the Extrusion Mulitplier, then fine-tune the Z...

Re: Coordinating MakerGear motion with a dispensing pump

the printer can communicate directly with the dispensing pump That seems unlikely, as the pump has an old-school RS-232 port, printers have USB ports, and neither has the ability to produce the ASCII-oid protocol required by the other. Back in the day, folks replaced the extruder with a screw-press...

Re: AC powered bed heater

an AC powered heater Imagine the excitement when a wire carrying line voltage frays and shorts to something else in the braided sheath! Instead, use the RAMBo's MOSFET to control an off-board DC-DC solid state relay, rewire the heater to run from a (somewhat) higher voltage external power brick, an...

Re: Intractable bed adhesion issues

How do i print these? Just add 4 square objects to the tray, one in each corner? Here's the process I still use: https://softsolder.com/2016/04/05/thinwall-and-solid-boxes-for-3d-printer-calibration/ You don't need to use my OpenSCAD source code to generate the models, but you must know the dimensi...

why does the tiny hole have to be so nice?
It's art! [grin]

AFAICT, a nice result means the manufacturing process is under control.

It works that way in my shop: when all my mistakes cancel out, even the swarf looks pretty!

Re: size of socket on extruder pinch-wheel shaft

what looks like a tiny torx socket at the bottom That's the metal pushed downward while swaging the hex socket into the bolt head. Basically, you drill a round hole into the bolt head, then force a hexagonal punch into the hole until it bottoms out, which scrapes six metal "petals" off the hole's w...

Re: Happiness with BlTouch sensor in M2?

And NEVER to try to modify code after 8:00PM. Protip: change exactly one thing at a time and verify what you expected to have happen actually happened! You should also expect things can change even when you don't change anything: https://softsolder.com/2018/02/13/m2-platform-alignment-and-nozzle-he...

Re: strange print

Disassemble into parts the extruder motor Looks good! The motor pinion (the smallest gear, the one on the motor shaft) is a failure where one careful inspection eliminates a whole bunch of mysterious problems: don't feel bad you didn't find anything wrong. of course I mean +- 0.05 mm We've seen def...

Re: Can anyone help identify My problem with my print?

they get lower and lower as the extrusion goes down Did you measure the actual filament diameter and calibrate the Extrusion Multiplier? If not, then the slicer doesn't know how much plastic it's extruding and will produce poor results. Rummaging around the forums will unearth a bunch of discussion...
