Re: RAMPS v1.4 based pen plotter - 11 years ago

Repetier also has corexy and hbot configurations.

I think Mach3 does this, and you can configure the post processor to be friendlier for reprap host programs.

D9 is on the left, it is a power output terminal.

Re: Cooling Fan: no voltage - 11 years ago

i figured out the SD card issue, inUi.h I had to manually add #DEFINE SDCARDDETECTINVERTED true I looked up the FEATURE_CONTROLLER==10 (the correct value for me) and inserted the aforementioned line at the end of the "if" statement. (before the next "else" or "endif") Oh, and the FAN_BOARD_PIN actually is intended to be a cooling fan for the controller board. edited because i put "false" rat

Re: Cooling Fan: no voltage - 11 years ago

Ok, the numbering seems easy enought then (slaps head) Near the top of the configuration.h file, i see: #define FAN_BOARD_PIN -1 however, in my pins.h it sure looks like 9 to me.. /**************************************************************************************** * Arduino Mega pin assignment * ****************************************************************************************/ #

Finally got my PID motors working with my RAMPS 1.4 - 11 years ago

the motors: SNAP SM-062: completely integrated motor, gearhead, encoder, amplifier and servo controller (info website) (sales website) After waaaay more learning than i was prepared for (i know nothing about electronics of any sort), and constant communication with the man who designed these motors, I have finally gotten these things running via step/direction commands, dirrectly from my RAMPS

Re: step/direction before drivers - 11 years ago

The Manual for the control chip (driver) states the following: Step and Direction Signal Timing The step pulse should be a rising pulse with a duration of at least 0.2 microsecond. The direction signal should be stable for at least 6 microseconds from the rising edge of the step pulse.If you have an indexing system that does not hold the SDIR signal stable for at least 6 microseconds, you can fi

Cooling Fan: no voltage - 11 years ago

Ok, i am running the latest Repetier firmware, and i am aware that D9 is the normal place for a cooling fan. the latest Repetier has an online pre-configuration tool, which is nice, i guess, and of course, if has a preset for the RAMPS 1.4 board. However, when i activate the cooling fan via M106, no matter what speed, i get novoltage across the 12V terminals at D9. I am still pretty new (ok got m

Re: step/direction before drivers - 11 years ago

for anyone who may wish to know, i believe i have found the relevant information, in the driver socket diagram provided by the Pololu chip. now that i see this, i can also verify against the schematics listed on the wiki page for ramps 1.4 does anyone know if there are any additional steps i should be taking in my firmware (repetier) for this type of operation? if the board is epecting signal

step/direction before drivers - 11 years ago

Hi all, I have some servo motors that I would like to use for a 3d printer, the man who designed them has specified that in order to accomplish this, I need to wire them to the step/direction commands coming from the atmel, before the driver. These motors will be powered via a common hub, and feature eeprom/driver chips. I have ordered a sainsmart ramps 1.4, but due to either bad documentation,
