Archim2 Journey

Downloaded the Firmware Here

Allted/Marlin

• After reading the forums, it seems like this may not of actually been fully baked yet…if it has could someone please point out the error of my ways?!

Reviewed this for wiring and additional notes @ https://reprap.org/wiki/Archim2

• Needed to jumper power from imput C to input B
• Install Archim board support: https://reprap.org/wiki/Archim_v1.0#Install_Arduino_Addons
• Install TMCStepper library: Arduino IDE-> Sketch menu -> Include Library -> Manage Libraries -> install TMCStepper

Added the following to configuration.h

• #define X_DRIVER_TYPE TMC2130
• #define Y_DRIVER_TYPE TMC2130
• #define Z_DRIVER_TYPE TMC2130
• #define E0_DRIVER_TYPE TMC2130
• #define E1_DRIVER_TYPE TMC2130

in configuration_adv.h uncommented(removed the “//”)

• #define TMC_USE_SW_SPI

Display Issues

• I tried adding U8Glib, but it sounds like per Jeffeb below it’s already bundled
• My pinouts on the archim were backwards from the Full Graphic Smart Controller, so I trimmed the little tab on the connector so I could turn it around on the board end. BOOM

Dual Endstops

• Still need to rewire Y and Z from Series, Install the endstops, and validate the firmware config

Yeah. Archim was working well enough (I think the version you found). There is some trouble trying to attach a laser that we found. But the basics were working. In 2.0.6, it builds in platformio but not arduino and there are some open issues about the watchdogs not working right. So I would stay with this version for now.

[rbales79 (Roy)]

I compiled and got it moving fine with Arduino, just running into problems with the aforementioned issues.

I’ll try it with platformio and see if I have any better luck

[jeffeb3]

No, I think the version you have is pre-2.0.6. So it should build with arduino and not platformio. I think that is preferred in this case.

They also bundled u8glib, I think. So you shouldn’t need to install it separately.

So what is the remianing issue?

[rbales79 (Roy)]

I didn’t find better luck using platformio
‘DIO105_WPORT’ was not declared in this scope
‘DIO105_PIN’ was not declared in this scope

My display didn’t light up, in fact when i tried to turn the knob it was crashing the board, it disconnected and reconnected to my laptop. Turns out that the cable pinouts for this board were backwards, so I removed the notch from the cable, flipped it over, and BOOM…Display

[rbales79 (Roy)]

Getting error when i try to compile with #define Z_DUAL_STEPPER_DRIVERS, tried it with just the Y and that compiled but still didn’t work as expected. I’m assuming I have to actually modify the pins file.

#error “Z_DUAL_STEPPER_DRIVERS requires Z2 pins (and an extra E plug).” & “No E stepper plug left for Z2!”

You should be able to set EXTRUDERS=0 to get an extra driver.

I get an array error when I do that, I had tried previously, and still looking through marlin forums and issues…

When i did it with just the Y, the Y the one attached to E1 still didn’t move like it was supposed to.(I’m assuming because of the pins)

I read @vicious1 instructions, and it makes sense, but making sense and actually implementing are two different things.

Ryan, any help with the above?

[rbales79 (Roy)]

Nevermind, I got it working, changed my PINS.Archim2 to look like this, are there better spare pins to use? i used some from the GPIO connector for the moment.

[vicious1 (Ryan)]

If it works it works. I have not had any experience with that board in years.

[rbales79 (Roy)]

I got it because the Rambo was out of stock at the time, and it didn’t seem really clear that it was going to be more than flash and run, but it’s good experience, and I’m excited to get this thing cutting!

[HelloFellowNerds]

What repo did you use for the arduino software as the repository URL? I seem to have loaded the archim1 board, but can’t find archim2.

[HelloFellowNerds]

Okay, I think I’ve actually got the right repo/board. Can you share the final versions of the configuration.h & Configuration_adv.h & pins files? I’m making some progress from your previous posts, but still feel like I’m flying blind here.

[rbales79 (Roy)]

Give me a few, I’m getting you all the things…assuming you are doing dual endstops?

• I thought this would be a download, install, win…it was not

This is the firmware as I edited on 8/17/2020 I will not be keeping up with it as I moved to Bart Dring’s Board.

Dual Endstops

• rewired Y and Z so that Y2 is on the E0 plug, and Z2 is in the E1 Plug. Took me a minute to figure out which way was the right way wiring the endstops as they’re not clearly marked on the limit switches. for me it was black at the closed end of the switch V, white in the middle

You will need to modify the pins_ARCHIM2.h file, there may be better pins to use, I think i picked ones from the breakout.

At this point I was able to successfully flash the firmware, and tested all the motors and limit switches. I was a bit surprised that Z2 used the top left connection if you’re looking at the board with the stepper motors at the bottom, but all steppers and switches flagged appropriately. you can test this by sending m119 gcode with none or a single limit switch tripped and it will tell you which one is tripped.

[HelloFellowNerds]

Holy smokes it worked. Thanks for your assistance buddy. I’ve still gotta map out the limit switches & etc, but I’ve finally got all of the steppers moving. Thanks again!
