I'm afraid that if a user will have filament remains on the hotend which can block the circuit, it will be enough to destroy something..
Ben Levi I’m sure it’ll use the wipe pads beforehand.
Wipe pad and wiping procedure are pretty useless, on my lulzbot mini if I don't scrape by hand the nozzle I have 70% chance of failure. And as Ben Levi said that does fuck up things : on the mini it's the linear bushings on the X-axis that get destroyed when the nozzle crashes into the probe points.
That being said, nowadays stepper drivers can detect crashes so that may be a way to mitigate this
@@MrBleulauneable but by using stall detection you lose a lot of torque.
Ben Levi The nozzle does need to be clean. I check and wipe the nozzle at the start of each print. The start g-code warms the filament and backs it out prior to the wipe, then cools it down to avoid oozing *before* it does the bed-level. But that said, I have had the occasional dirty nozzle. The printer does limit how far it it will plunge the nozzle in the washer (the bed will flex without any damage) before it gives up and realizes it *should* have had a good contact.
In summary... even if the bed level fails it will *not* damage the printer.
Side note: I swapped the factory hardened-steel nozzle (with TAZ Workhorse & Pro, the Mini 2 doesn't have a hardened-steel nozzle) with the E3D Nozzle-X. It has a poly-phobic coating that makes it more difficult for filament to stick to the nozzle and much easier to wipe clean for the little amount that might stick.
invented by lulzbot???? pretty sure this was already a feature in marlin
dont be idiot .... and check before speak :) github.com/MarlinFirmware/Marlin/blame/9ade72aee94981b26be0ca125ab487166d0bd7e3/Marlin/src/gcode/calibrate/G425.cpp - first push buy luzbot ;)
Can I hope for Lulzbot kit to upgrade a Taz6 to use these new features?
Really hope this is also applied to the TAZ6 😩
How do I run this command on my workhorse?
interesting... I thought, backlash in 3d printer is always some sort of mechanical problem, and when everything works fine - backlash is near 0.01mm and unnoticeable in the prints.
It is a mechanical problem. However it can be predicted and calculated in advance. The problem doesn't disappear with this. It *compensates* for it.
people dont understand how much of a big deal this is for budget printers LOL
5000 dollars is budget to you???
A 5 volt electrical current.... Really.... Volt = voltage & Amps = current. From such a high-tech company you'd at least expect that they use these right terminology, you just make yourself look stupid imo
idk
5 volt it's the tension... the potential diference
And electrical current can also refer to the phenomenon of electrons in motion within a conductor (like potential difference) without referring exactly to current as a measure (amps)
(At least here in Argentina we say "220v of current" and we say amperes to refere to "current"
@@wachocs16 your terminology is incorrect. A high tech company should have used the correct terms when refering to voltage and current. a 5V 2A current (for example) cant just say 5V current, current isnt measured in volts, its measured in AMPS and the voltage is the driving force behind the current.
