Re: Horizontal axis inaccurate - M3 SE

Not by a lot but enough to have customers … say a part is off What tolerances do they expect? It seems everybody wants micron tolerances, even for Stanford Bunnies. [sigh] If ±0.1 mm will suffice, it's likely a mechanical problem. Check for: A loose lock screw in a stepper drive pulley A loose moun...

Re: Increase baud rate?

the Pi’s used in Octoprint setups can't feed the gcode to the printers fast enough I'd be unsurprised, as the Pi's USB / network hardware leaves a lot to be desired. In fact, the network runs over the USB link inside the chip, so I'd expect watching the video camera would have more effect on the re...

Re: Increase baud rate?

like to change it to 250000. Depends on what hardware & software you're driving it with. CH340 and genuine FTDI USB-to-serial chips don't do 250 kb/s and counterfeit FTDI chips are unstable at any speed. Marlin's buffer isn't more than a few hundred bytes, tops, because Arduinos don't have much int...

Re: Streaking on the surface finish of PETG print

diagonal streaking issues That's the nozzle just kissing the top surface as it travels from one spot to another. If you haven't recalculated the Extrusion Multiplier to match the new filament, the layers may be ever so slightly overstuffed. Rather than blindly reduce the EM, make the measurements, ...

Re: Bed won't heat...

As soon as my z endstop triggers, the firmware resets. The Z endstop cable is plugged backwards into the RAMBo socket. The RAMBo socket has three pins: [+ - S]. The two-wire switch cable ends in a three pin connector shell (*) with one empty contact. Unfortunately, the cable connector is not symmet...

Re: Bed won't heat...

Measuring the voltage across the bed power pins, I get 12v With a 12 V heater, the most likely problem is at the power input connector on the RAMBo board. The wires from the 12 V power brick generally work loose inside their screw terminals, whereupon the absurdly high current heats up the weak joi...

Re: No Need To Slic3r, Native .g and .gcode Files

3D CAD software out there that natively creates .g or .gcode files It's not just a 3D printing thing. CAD (computer-aided design) software produces a solid model, which a CAM (computer-aided manufacturing) program then converts into the specific dialect(s) of G-Code required by whatever machine too...

Re: M2 E Max Temp Err

throwing an error message of "Max Temp" Order a new extruder thermistor, install it, recalibrate the initial Z offset, and you're done. Search the forums for +max +temp (the + signs require the word to appear, as quoted strings don't work the way I expect) and you'll find plenty of discussions, wit...
