Re: Communicating with another Arduino over i2c

Indeed! I found out over at reprap forums that the address needs a left bit shift in order to work properly. Here's the code I am using now: HAL::i2cInit(100000L); HAL::i2cStartWait(4 << 1); HAL::i2cWrite('a'); HAL::i2cStop(); Right now I'm trying to figure out how to get a float converted to a stri...

Re: Communicating with another Arduino over i2c

This is the kind of functionality I'm getting at. Right now the actions are soley controlled by the external arduino though..

Re: Communicating with another Arduino over i2c

http://reprap.org/wiki/Rambo_v1.2 Says it has spi pins. Looking at the RAMBO schematic at the same link tells me that that there are dedicated SDA/SCL pins for the Rambo's I2C port which are not shared with the SPI or EXT headers. I also see 10K pullups on both lines. Now whether the I2C code in th...

Thanks, I've already gotten two arduinos talking and have the setup complete, I'm just not sure where in the Repetier firmware to put the communication code?

Communicating with another Arduino over i2c

I'm looking for a way to connect the RAMBO to another arduino via the i2c connection. I'm going through the source code but can't find any good examples of opening up a simple connection and writing strings out. Does anyone know where I can find some sample code on creating some methods like this?

Re: Unsolved Mystery. Weird Z0 behavior around build perimet

Ah so it's the same procedure in the manual, cool I'm done up to that step.

For step 5, when I move the nozzle to the opposite end of tower, the nozzle lifts from the bed. The instructions say to adjust the end stops. I'm guessing this means the two towers closest to the nozzle and not the far one?

Re: Unsolved Mystery. Weird Z0 behavior around build perimet

Okay, I'm going to suggest what I remember my steps for resolving this were: 1) set the 0,0 point at your desired height (paper thickness). 2) Set all three tower points at the same height. This should now mean the plane is level? Not necessarily. 3) Move the hot end from A tower position and 0,0, ...

Bed Level Calibration Issue

I'm having a bad time getting the bed calibrated on my max v2. Following the manual, at each of the pillars the nozzle is the same distance from the bed. When printing a test circle at each of the pillars the filament is being pressed into the bed correctly, but between the pillars either it's too c...

Re: Sound deadening material

There are holes in the frame to access all 4 screws that hold the motor in place. Undo those, pull the motor off, install the dampers and reinstall it.

Re: Sound deadening material

I have the dampers on my motors and the pads under the base.

You shouldn't have to take the whole printer apart to install the dampers. I would highly recommend them also, they make the printer much quieter.

The opposite problem haha! If I print farther away from the bed for the first layer would I get less sticking? Or i...

Yes I suppose this reel doesn't want to stick well. I'm interested in getting a sheet of PEI, would the .03" 12"x12" suffice?

Re: PEI print bed surface experiments

Ya it's currently lifting around 2mm, the part just really doesn't have any adhesion with this reel of filament I'm using, others have been fine.

Also, is the .03" thick stuff recommended or is the .09 better somehow?

How much horizontal force can a printing piece take before it pops off mid print? I have issues with some rolls of filament having a nice first layer but only take a pound of pressure to break the PLA off the bed at 60 degrees. On taller pieces if the nozzle catches on anything it rips the print off...
