Re: Is 3.00mm filament dead? - 26 days ago
This is still much debated... I say yes 3mm is dead. (And yes I still have machines that are 3mm, but haven't used them in some time.) But many older machines are still out there and use 3mm and its still available but is way less abundant than 1.75 Also TPU is easier to print in 3mm,by Dust - General
Re: is it possible to replace a stepper moter with a dc moter you found in a cheap toy car - 7 weeks ago
Z is the axis that requires the most accurate movements Otherwise your z0 is to low or to high and that is the end of that print or even the hotend. And no. All 3d printer firmwares are step and direction engines. You would need to provide a step and direction interface to the DC motor, with sufficient electronics that 1 step moves the motor a set repeatable small distance.by Dust - Mechanics

Re: Tinybee z offset - 8 weeks ago
The Tinybee cannot do live babystepping It is because they use a io expander, a serial stream to a buffer for the stepper driver step and direction io lines, The current implementation does not allow direct manipulation of of the step pins that babystepping requires.by Dust - Firmware - Marlin
Re: bltouch G28Z homes only if i run M43 S first - 2 months ago
that is a kludge.. Normally a bltouch operates in Open drain mode "In electronics, an "open drain" (also known as an "open collector") output pin is a circuit configuration where a transistor (or MOSFET) is used to pull the output pin to ground (low voltage) and leaves it floating (high impedance) when the transistor is off. " Ie it needs the pullup resistor enabled for a logical high of 3.3vby Dust - Firmware - Marlin

Re: Enable 12v-pin on board (MKS robinv2.3) - 2 months ago
It looks to have inbuilt resistors. so it should work by simply plugging it into 24v and turning the switch on Note. It has polarity. It will only work if plugged in the correct wayby Dust - Firmware - Marlin
Re: Enable 12v-pin on board (MKS robinv2.3) - 2 months ago
the 12/24v pin is directly connected to the power supply (via fuse f2) . there is no settings for it. It is always on if the power supply is on. They are labeled 12/24v as they are the same voltage you supply the board power pins with, ie 12v or 24v what sort of led strips? neopixels or ws2812 wont work as those need a data pin. also most leds need somthing to limit the current, or they justby Dust - Firmware - Marlin

Re: FAN ports confusion with btt skr mini e3 v2 - 2 months ago
You may have noticed that the fan mosfets control the gnd line, as such you cannot share fan gnds with other fixed gnd lines. a short to real gnd and the fan will always be on. Step one would be to unplug the fan and stick a probe or meter in the fan port using both pins. and play with M106/M107 gcodesby Dust - Firmware - Marlin
Re: FAN ports confusion with btt skr mini e3 v2 - 2 months ago

Re: ANET A6 Marlin 2.0 - 3 months ago
So your telling me that using M119 and looking at X-MIN endstop (since configuration.h should have #define X_HOME_DIR -1) says OPEN when the endstop is not activated, and says TRIGGERED when the endstop is activated? And the same with Y-MIN ? If so this should be homing fine. please attach your Configuration files for examination.by Dust - Firmware - Marlin
Re: Trying tô increse maximum temperatura of the hotend - 3 months ago
This is related to your hardware The thermistor type defines the highest readable temperature Eg type 1 thermistor The highest value in the table is 320 Next you have #define HOTEND_OVERSHOOT 15 // (°C) Forbid temperatures over MAXTEMP - OVERSHOOT You need some overshoot so firmware can tell its over the temperature you set so the max usable temperature is 320-15 = 305 This can be furby Dust - Prusa i3 and variants
Re: ANET A6 Marlin 2.0 - 3 months ago
How are you testing endstops? Note: moves (G0, G1 etc) are not stopped by endstops, endstops by default are only used during homing moves ( G28 ) Unless you enable ENDSTOPS_ALWAYS_ON_DEFAULTby Dust - Firmware - Marlin
