Re: lcd screen acting out? 12v problem? endstop short? IDK - 9 Jahre zuvor

Are you sure that you have not plugged in the endstop connector the wrong way? Since this would cause the end switch to make a short between GND and 5V, shutting down immediately the electronics and often also destroying the 5V regulator on the Mega board. The latter could explain why it now only works with the USB connected (which brings the 5V directly).

Re: Problems after swapping drivers - 9 Jahre zuvor

Could it be that your new stepstick uses a different chip (e.g. DRV8825 instead of A4988) which use different jumper setting for microstepping? So e.g. if the new stepstip is DRV8825 and is set to 1/32 and the old ones are A4988 at 1/16 you would get the y-axis scaled to 50%. To remedy this, you can either change the jumpers underneath the stepstick to use the same stepping (if possible) or cha

Re: Stepper driver help - 9 Jahre zuvor

I entirely agree with dc42 that the Arduino Pro Mini is not the best choice, but it actually does have the 5V regulator onboard. So that it's possible to run it from 12V - it's the pin labeled "RAW". Here a link to the schematics for those interested.

Re: RAMPS Beginners Question - 9 Jahre zuvor

Is it possible that your endstopd are plugged in the wrong way, so that the switches are shorting 5V to ground instead of pulling down the signal line to ground? Unfortunately, the RAMPS endstop pins are in the order "+-S", so when an endstop that has a switch between "-" and "S" is plugged in the wrong way, it will cause a short. PS: BTW the Sanguinololu has the signal pin in the middle, so

Re: Z-Nullpunkt - 9 Jahre zuvor

Könnte es sein, dass dein Z-Endstop nicht richtig funktioniert? Wenn er kurz nach oben fährt sollte der Z-Endstop (aus)schalten. Wenn das nicht geschieht, dann fährt er auch nicht nach unten. Also mal Z-Endstopschalter und -kabel über prüfen und mit M119 schauen, ob er auch so schaltet, wie er sollte.

Re: Problem with my sanguinololu.. - 9 Jahre zuvor

At least it's good to know that there was no negative voltage As for the extra sensor pin, you could use one of the five analog input pins A0-A4 on the 14-pin extension header. But you have to add a 10uF capacitor to ground and a 4k7 resistor to 5V yourself (see "Thermistor" section of the schematics on the link in my first message). You could e.g use a 0.1" 2x2pin connector and bring out A4

Re: Problem with my sanguinololu.. - 9 Jahre zuvor

Quoteglub0x So after some testing, the pin n°19 is always at -0,7volts which is not nice... Do i have to replace the 40 pins chip? Very strange that you get a negative voltage... Have you measured this with only one power connected (either 12V PS or USB ) ? Do you then still get negative voltage? Because, as I understand it, there should not be negative voltages anywhere on the board. So if

Re: Problem with my sanguinololu.. - 9 Jahre zuvor

The pins HEATER_0_PIN=13 and HEATER_BED_PIN=12 are defined in pins_SANGUINOLOLU_11.h if you are using Marlin 1.0.2 or newer (or in pins.h for older versions, search for MOTHERBOARD == 62). There you can switch the pin numbers. If you have a voltmeter, you can also first check the voltage on HEATER_0_PIN to see if it goes high when switching on the hotend. Logical pins 12 and 13 are on physical

Re: how to assign letters/numbers - 9 Jahre zuvor

Re: Adjust the Z while printimg the first layer - 9 Jahre zuvor

I know this problem, too. But my solution is to simply finetune the Z-level of my i3s manually by turning the Z-couplings slightly while the skirt of the first layer is printing. For this, you must make sure that the Z-motors are disabled when not moving (#define DISABLE_Z true) so that the Z-motors rotate easily when not moving between layers. It takes a little practice to rotate both coupling

Re: Marlin default steps per axis does not change - 9 Jahre zuvor

Do you have the EEPROM activated? If so, you need to manually send a "M502" to load the values from Configuration.h and then "M500" to store these new values in EEPROM. Otherwise the old EEPROM values will be continue to be used.
