Re: What settings causess these wall artifacts?

ABS filament print very clean horizontal lines per layer nozzle size 0.5mm, layer height 0.4mm I have my extrusion multiplier to 0.95 First of all, the extrusion mulitplier is not a free variable. You must calibrate the EM so the slicer and the printer agree on how much plastic comes out of the noz...

Re: M2 lost motor control

manually move the bed position Betcha you jostled the printer or the power cable when you did that; I have one of those t-shirts … TURN OFF THE AC POWER, then check the motor power connector on the RAMBo board. This connector may have a separate cable from the power brick or have short wire jumpers...

Re: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting

an immense amount of force to finally get it to break at the damaged area. The thermistors don't draw any current worth mentioning, so as long as there's a single non-quite-broken strand of wire making the faintest contact, it'll (seem to) work (intermittently) just fine. Pulling on the wire might ...

Re: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting

Is it possible it's the bed thermistor? The video seemed to show 26 °C for Extruder 0, which would definitely be a problem. The other two temperatures looked fine. would it be possible for extruder 0(while not being used in this print) to cause the mintemp? The firmware doesn't know your intentions...

Re: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting

Screen shows Err. MINTEMP. Which means it wants a new thermistor on Extruder 1. Seeing the error message definitely assists debugging … Z axis weirdly binds when lifting The motor must lift that honkin' big aluminum slab, so turn off the power , unplug the Z axis motor, and turn the shaft by hand t...

Re: strange heat bed temp reading

What can cause this ? A failing thermistor: replace it now! It could also be an intermittent wiring connection, but my bet is on the thermistor itself. When the thermistor (or connection) fails with (briefly) a higher resistance than it should be at the correct temperature, the firmware thinks the ...

Re: Threaded rod that is not threaded

How could this have been made accidentally?? Those threaded rods are rolled, not cut: if the operator misaligns / swaps the rollers, the rod won't feed and you get those pretty rings. A promo video gives the general idea: https://www.youtube.com/watch?v=rwArBBcUNr4 A few minutes on Youtube after se...

Re: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting

the position readouts starts going crazy It looks like the positions accurately display the G-Code coordinates being sent to the printer, so I think S3D (which is what I presume you're using) has lost track of what's going on. The printer is telling it to STFU and it's still sending G-Code. If S3D ...

Re: Changing block heater from 0 to 1 on RAMBO

activate my extruder heater, my USB disconnects Perhaps one of the power supply inputs has worked loose: suddenly drawing 8-ish amps can glitch the supply and away you go. If any of the screws on the power input block seem loose, extract the wire and make sure the connector guts are still in good s...
