Re: Prusa bricht Druck ab - 9 Jahre zuvor

Ich hatte das Problem mal in meiner Werkstatt. Jedesmal, wenn ich das Licht (Leuchtstoffröhre) ausschaltete, dann stoppte der Drucker. Die Störungen könnten also auch von einem anderen Stromverbraucher via 230V Leitung kommen. Jetzt hab ich LED-Leuchten in der Werkstatt und das Problem ist verschwunden

You might also consider wiring the two Z-motors in series instead of parallel, this way you are sure that both motors will always get exactly the same current.

Re: Melzi V2 board on Prusa i3- commissioning - 9 Jahre zuvor

@Weskrauser: I think that you should insist that your seller sends you the configured(!) source of the firmware for your printer. Because without it, you won't get far anyway. Sooner or later you want to do some upgrade of hardware or software, and then you'll need to be able to flash the firmware again. If your seller does not want to give you the configured source code, you will be better of

Re: Melzi V2 board on Prusa i3- commissioning - 9 Jahre zuvor

Are you sure that what you are seeing in the first 3 seconds after powering on is not just due to the boot process, i.e. just happening in the time between power on and the firmware starts controlling actively the pins? I don't have a Melzi, but also on my Sanguinololu the fan turns for a few seconds before Marlin has bootet and switched if off. And the LED on the RAMPS also blinks for a second

Re: Extra temperature monitoring sensors - 9 Jahre zuvor

If you just need one additional thermistor, you can just connect it to T2. If you need to connect more thermistors, you can use any of the non-used analog inputs on connectors AUX-1 (A3, A4) and AUX-2 (A5, A9, A10, A11, A12) and connect the thermistor using the same R=4k7 C=10uF circuit as is used for T0,T1,T2 (see the RAMPS schematics). So the hardware part is easy, but you will also need to m

Re: Temperature drop from 208 to 195 - 9 Jahre zuvor

Quotevillainous The power supply I have has two outputs, so if I were to tie them together theoretically I could get 24V into the printer. In addition to dentist's point, it is also quite likely that the 2 outputs of your power supply are not galvanically isolated from each other, so that they share a common ground. In this case trying to combine them in series would result in a short.

Re: Temperature drop from 208 to 195 - 9 Jahre zuvor

If the heating of your hotend is very weak and needs all the power just to climb to 185C, it is normal that it will cool down when printing and is fed with new (cold) filament. Check if the connections of the heater are ok and measure the resistance R of the heater, then compute with the voltage U of your power supply compute the wattage P=U*U/R, which should probably be at least 25W, but better

Re: Z carriage is not consistent - 9 Jahre zuvor

Are you sure that your printer supports the (very high) HOMING_FEEDRATE and your DEFAULT_MAX_FEEDRATE for the Z-axis that you are using? If not, your Z-motors might loose steps and get out of sync. Does the problem still persist if you lower the Z feedrates to 2 or 3 mm/sec? Once that works, you can slowly go up with the values again and see how much still works okay.

Re: LED 3,3V an 25,6V - 2 Widerstände parallel? - 9 Jahre zuvor

Dein Link zeigt aber auf ein Widerstandsnetz mit 4 Widerständen in einem Gehäuse und die 1/4W Belastbarkeit bezieht sich auf die Summe aller 4 Widerstände. Im Prinzip kannst du die 1/2W leistung schon auf 2x 1/4W parallel verteilen, aber ich würde da nicht zu knapp rechnen mit der Leistung und besser gerade auf 1W (resp. 2x 1/2W) gehen.

Correct, they are cut off from supplying 5V to the RAMPS. As for your question: QuoteDoes the Due need its own ( normal) power supply or is it fed from USB or Ramps PCB ?? It's the same as for ordinary Mega+RAMPS: the Due will run from the RAMPS 12V (provided diode D1 is installed), from the USB or from the Due's powier jack.

Re: Marlin firmware - Heat Bed PID PWM won't go higher than 127 (50% duty cycle) - 9 Jahre zuvor

As for getting the heatbed to higher temperatures, here is what I did: - use a piece of corkboard as insulation directly underneath the heatbed - cover the heatbed with a piece of thick corrugated cardboard while heating up - increase the output of the 12V PSU to 13.3V WIth that I can get the heatbed in reasonable time (~4min) up to 120 C.

Re: Marlin firmware - Heat Bed PID PWM won't go higher than 127 (50% duty cycle) - 9 Jahre zuvor

Julian, are you sure that you are not just stumbling over the fact that Marlin does not show the PWM (as one would expect!) from 0 - 255, but somehow only from 0-127 - i.e. the least significant bit is lost. So if you see "...B@:127" in pronterface, this means you have a full 100% duty cycle.

Re: DIY Tiny OLED I2C full graphics controller - 9 Jahre zuvor

We don't need physical package pin numbers in the pins_SANGUINOLOLU_11.h. What we need are the Arduino digital output pins numbers (Dxx) which correspond to the A1/A2/A3 analog pins. Usually they occupy the numbers just above the "normal" digital output pins. According to the wiki these are A1->D30, A2->D29 and A3->D28.
