Your first link shows a pulse-torque diagram which stops at 5000 halfstep pulses per second, which would correspond to a max of 750rpm. The actual speed you can reach with the 16MHz Arduino, depends also on how your software is implemented.von enif - Stepper Motors, Servo Motors, DC Motors

If you get the same error messages as murphyrh, I would make sure that you do not have any copy of Marlin in the libraries directory.

Which version of Arduino are you using? What is your board setting in Arduino? Are you sure that you are connecting to the right port? (Does Tools/Ports also show other ports?) Does the Arduino show as a USB port in the Windows hardware manager? If not, you need to install the drivers for the TTL-USB chip on your Mega board (usually either CH340 or FT232RL chips).

Re: Guide me with Marlin firmware and full graphic LCD - 9 Jahre zuvor
Before continuing with you RAMPS and LCD tests, I think you should get first your Arduino IDE working properly. Since you played with ISP programming, you might have overwritten somehow your bootloader. So try to install the bootloader again on your Mega 2560, for this you will need your ISP programmer. If after that you can still not install Marlin over the USB, report back here with the detavon enif - Firmware - mainstream and related support

Das sieht nach einem Problem mit dem DIR-Pin des des Extruder Stepper Drivers aus. Ich würde zuerst sicherstellen, dass die Verbindung vom E0-DIR Pin zum entsprechenden uP-Pin (sollte Pin 28 sein auf dem Mega sein) gut ist und dann mal am E0-DIR Pin die Spannung messen während dem Testen, sie sollte je nach Bewegungsrichtung ~0V oder ~5V sein.von enif - Extruder, Hotends & verschiedene Materialien

Es-tu sur que c'est le fusible sur le RAMPS? Verifie aussi si ton regulateur 5V sur le Mega fonctionne encore (p.e. installer le sketch blink, et voir si ca clignote quand tu ne branches pas sur USB, mais juste par alimentation externe).

Sind deine Z-Motoren parallel oder in Serie geschaltet? Wenn parallel, dann bekommt jetzt jeder Z-Motor nur ca 500mA. Anstatt den Strom höher zu stellen, probier doch mal die Motoren in Serie zu verkabeln. Dann bekommen beide den gleichen (=eingestellten ca 1A) Strom, auch wenn sie nicht ganz exakt die gleiche Impedanz haben.von enif - Elektrik & Elektronik

Re: Turn on a LED while extruding (only) - 9 Jahre zuvor
I don't know why you need this LED. But since you do, why not implement it directly in the hardware? E.g. with a ATtiny85 that reads the extruder's DIR and STEP signals and switches the LED accordingly. This way, you would not have to modify the firmware again whenever you need a firmware upgrade. Also, this would even allow you to count the forward and backward steps, so that the LED wouldvon enif - RAMPS Electronics

Re: Problem with my sanguinololu.. - 9 Jahre zuvor
I also remember that the first batch of IRLB8743 I bought had a much higher ON impedance than it should be according to the specs - so they got much too hot. The second batch was ok and the MOSFETs kept cool. You can measure the voltage drop over the MOSFET while heating between the "-" of the heatbed and the GND from the power supply. For 10A current it should not exceed 50mV, which would meavon enif - Sanguino(lolu)

Re: Problem with my sanguinololu.. - 9 Jahre zuvor
Yes, the pin label D12 PWM on the Sanguinololu is wrong, it should be D4. And using (D)4 for a PWM output pin and (A)4 (=D28) for an analog input pin sounds indeed strange, but it should work.von enif - Sanguino(lolu)
Re: Problem with my sanguinololu.. - 9 Jahre zuvor
If you connect the heatbed directly to the Sanguinololu, the MOSFET also gets hot. But it's better not to do that, since the traces on the PCB are quite weak, so you risk burning them at >10A (see here). So I never connect the heatbed directly to the Sanguinololu, but use either a cheap automotive 40A relay or more recently also a sevenswitch. As MOSFETs in the sevenswitch I use IRLB3034, tvon enif - Sanguino(lolu)

Re: Ramps 1.4 current for 2 heated bed - 9 Jahre zuvor
I guess that two sevenswitches (or relays) are needed anyway since you probably need to control the temperature of each bed individally. The resistance of the MK2s may vary quite a bit, so I don't think that controlling both with a single thermistor will work well.von enif - RAMPS Electronics
