ok the good thing is that you can communicate with the alligator board. if you can pull up the serial port, and get OK messages, then you are in great shape. you should be able to bounce between the laptop and the raspi. the 40 pin connector is tied to the raspi-config settings, i'll be rebuilding my delta this afternoon so i'm updating my toolchain, i'll post if i find anything along the way.

@pieri70:
i'm building a 2nd printer as a corexy as well. i plan to push the reprapfw on to my 2nd alligator board for that. i'm within about a day to a week of doing so. if that works well i might just re-configure my delta, as it's undergoing a new arm and bltouch sensor probe upgrade, and i have to tweak the z-probe sensor config. that is the only reason why at this point i would have preferr

Hello Marco,
i ve many Problems to install and running Repetier-Server in an Rasperry Pi 3 with Alligator. The Problem seems to be the Wireing from Rasberry to Alligator, i get no right Connection to the Alligator.
Is it possible to give us an Guide from beginning to running Repetier-Server ? Since you Guide here, there are so many changes in Soft- and Hardware, so i think its time f

a little word of warning about the fans, I might need some help determining if and what I did wrong, and what I might do to fix it.
last night, I was in the process of upgrading my system to finally include fan2. I bought a 24v fan, wired it up and plugged it in. all was fine, until I went to test the fan, and I heard some pop, and then my board essentially froze, and I had to make a hard rese

Hi Geotete,

All the PC's that I have only have USB3 ports, they don't work with this.
Used a laptop with 3 years and a USB2 port, and the upload was sucess!
I had a different experience.
Both my linux boxes were unable to communicate with the Alligator using bossac v1.3a (the same version as the arduino one).
The kernel sees the Alligator on /dev/ttyACM0, but someth

Geotete,
are you plugged into the native port while you are doing this, or the uart port? looks like you are trying to load the native port version, and I do not know if that would matter when using bossac. I haven't tried it yet... just starting to learn about it.

Ok I am finally coming back around to this question about mixing extruders,
if I understand the doc right, I would need to set 3 sets of M163 settings for each extruder's weight, and then an M164 to assign it to a virtual extruder, to set this up with 3 virtual extruders, each mapped to the physical extruders, is that correct?
if there a way to configure this in the config file instead of the

Repetier
Hey Marco? I don't think I ever got clarified; will the alligator board support microstep modes 1,2,4 and 8? I've honestly only seen references for 16 & 32,and all my stuff runs on 32 for my delta...but this 2nd printer might need a geared stepper.
I am looking at a geared motor for a z-axis design and would rather not microstep, and I would like to think lower microsteps are in the repetier

yea, my design doesn't account for a plywood base, just aluminum 260mmx260mmx3mm plate, a standard 220mm x220mm PCB mk2B heatbed, and about linear 700mm of 15x15 extrusion, so it is fairly lightweight. the big difference might be for me whether I put the motor on the frame and pull the belt, or mount the belt and pull the motor with the bed with the bracket. I wonder which would be easier on the

fatfredie: is that using a geared motor?
the_digital_dentist, I agree in principle what you are saying.... I was looking at the belt & pulley system specifically because of the success I had building a delta printer, and how well it retains it's position even after powering off; I imagine that the tension on the belt and the tension on the carriages hugging the bars add to it's ability to

Hi all!
I have an idea of using a NEMA 11 5:1 geared stepper motor for a z-axis belt and pulley concept for a large platform with a small motors that ride belts on the rails. the motor itself is a 11HS20, with 12Ncm torque, and 1.8 degrees/200steps/rev, and a 5.18:1 gear, that puts it at about .35 degress/step, or about 55.9Ncm (~4lb). that would give me in theory, 1028.571 steps/revolution, and

to test your motors, (without any power) cross the red and green, and then try to manually move the rod back and forth. if you have any resistance, they might be your pair. then attempt to do the same with red and yellow, red and blue. feel which ones give you resistance. once you've gotten a pair, it's just a matter of figuring out the pulsations. mine for example, are red/blue, and g

Repetier
I wanted to know if the repetier firmware and repetier host supports sending extrusion codes to multiple extruders simultaneously. not just codes to each extruder but be able to have all 3 divide up the extrusion by some percentage, and then apply that in steps to each motor, to achieve a specific color from the original 3MF or AMF file?

Mark O, your description is exactly the process, you folks are going through as I did, many, many, many times as I built mine (and sometimes still do in cases like these)
make sure that you have gone out to github and pulled in the alligator board arduino variant drivers for the arduino IDE. without that, it might make all this irrelevant...

Hello,
I was wondering if it was normal to put heatsink on the Alligator DR8825 driver? I had to do that because of thermal shutdown if the current is more than 2amps.
Do you also had this issue?
I also have a lot of problem using the Repetier firmware with my custom cartesian printer. But with MarlinKimbra4Due, I don't have any problem so far!

MOTOR CURRENT Is PERCENT
exaggerated its setting
#define MOTOR_CURRENT_PERCENT { 250,200,170,230,230}
I've been looking into this, I do not believe it is
MOTOR_CURRENT_PERCENT
it is
MOTOR_CURRENT
, now, if you are saying that 0-255 is a percentage of 0-100, then
- 128 = 50%, or 1.25a
-135 = 52.9%, or 1.32a
-170 = 67%, or 1.6a
- 200 = 78%, or 1.95a

My question is around the potential for filament color blending with up to 3 extruders. we have seen the potential for having multiple extruders, and E3D came out with the single head extruder, and there's a 3-filament diamond hotend nozzles just shipping to backers from indiegogo, and a 4-way nozzles on the horizon... they can all do multi-color prints.

Something that builds from an Arduino Due, you can start with ramps-FD for the cheap and quick and dirty learning and experimenting. if you want an all-in one board, smoothieboard, alligator board (what I used) and Duet are all good ARM options, depends after that what you want. reprap wiki site has a page out there for comparing the

I've tried both. I am currently a fan of putting it as close to center as possible. I've had it at the top, and the Kossel I built ended up being top-heavy. I used 1515 openbeam, and it's XL sized, so if you have some reinforced 2020 beams or better, you may have a good outcome from on top. it means you have to handle all your filament on top...

I don't know if it helps, but I've been staring at this schema for a while, and thinking what it might take to have an adapter made to take in the 2 connectors and output them in the proper order...
I wrote a blog post to start mapping that out...
now, unless there's a need for 3.3v on the 12864, i'm assuming that pin2 isn't really necessary.
