PrintrBot Plus LC

The Printrbot PLUS is the larger printrbot kit–containing an 8x8x8 build volume, laser cut birch construction, an assembled Ubis hot end, and 12mm Z-axis rods in an all-in-one kit. This kit also includes 1 lb of ABS filament.

This kit includes everything you need to build the printrbot PLUS:

printrboard: all-in-one assembled electronics with integrated SD card slot (no soldering required)
5 NEMA 17 stepper motors complete with cable ends attached
laser cut birch construction
a few printed plastic parts (gears, etc)
WOOD Extruder Kit
hardware (8mm smooth rods, threaded rods, and bearings

Z axis is 12mm smooth rods and 12 mm linear bearings )

assembled Ubis hot end
nuts, bolts, washers, zip ties
laser cut print bed
8×8 heated bed
misc assembled cables (no soldering required)
3 mechanical end stops (no soldering required)
micro USB cable

nozzle

The Getting Started Guide says that all Printrbots currently ship with 0.4mm nozzles.
The convention for identifying nozzles is based on notches (or "rings") cut into the sides (vertices) of the hexagonal brass "nut".
No notch = 0.5mm
1 notch = 0.4mm
2 notches = 0.35mm

unlock chip using flip

It seems that chip is protected. However, trying to erase and program it did destry data in it (expect bootloader) for some reason, and it seem that dfu-programmer doesn't know how to work with protection features.

So, next step is to try atmel's flip under linux but this also doesn't work well.

Hardware upgrade

RAMPS1.4 LCD 12864

RAMPS1.4 LCD 12864 Control Panel 3D Printer Smart Controller LCD Display $10

https://www.aliexpress.com/item/1-pcs-RAMPS1-4-LCD-12864-Control-Panel-3D-Printer-Smart-Controller-LCD-Display-Free-Shipping/32312042967.html
$10 - works well, needs custom cable, well worth it from usability perspective

LM8UU

10pcs/lot LM8UU Ball Bearings 8mm Bushing For CNC 3D Printers Parts Rail Linear Long Rod Shaft Part 8mm*15mm*24mm Aluminum Bush

https://www.aliexpress.com/item/10pcs-lot-LM8UU-Ball-Bearings-8mm-Bushing-For-CNC-3D-Printers-Parts-Rail-Linear-Long-Rod/32834729285.html
$4.24 - NOT recomended, worse that original VXB.com -- seller specified brand as FYSETC, parts don't have any markings

Y axis coupler

$0.75 - NOT for Y axis, since they are flexible

https://www.aliexpress.com/item/3D-Printer-Blue-Aluminum-Alloy-Coupler-for-5-x-5mm-5-x-8mm-Shaft-for-Stepper/32854452012.html
$0.71 - great, much better than 3d printed part

$1.90 - great, pully nut doesn't interfere with clip which is holding glass since nut is flush as opposed to 3d printed part

Y axes rod

T8 Lead Screw OD 8mm Pitch 2mm Lead 2mm 150mm 200mm 250mm 300mm 350mm 400mm 500mm with Brass Nut for Reprap 3D Printer Z Axis

$5.14 x 2 - great, our rods where bent from out of box

Needs 3d printed adapter for nut to fit: https://www.thingiverse.com/thing:2963508

Nut is friction fit which I consider somewhat as safety feature, if I found problems with it, I will probably add a bit of ABS goo in holes to fix it in place

bed leveling

self-made sensor from RFID card, paper clip and case intrusion switch, connected in parallel with z-axis switch (it has to be normally closed, so that trigger interrupts signal)

install sanguino board support in ardunino ide https://github.com/Lauszus/Sanguino
turn on power supply when flashing if you didn't disconnect steppers or it won't get enough power
burn boot loader using usbasp programmer from arduino ide to make arudino ide work for upload

This should allow you to send u-boot, kernel and initramfs to any tegra2 board which can be in APX mode without
modifying internal storage.

u-boot loads detects initrd (it's small enough thanks to MODULES_STRIP to be detected without CRC errors) but no output from kernel.

https://archlinuxarm.org/forum/viewtopic.php?f=23&t=10044&p=51142&hilit=ac100#p51142

suggests CONFIG_TEGRA_DEBUG_UARTA instead of CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA but it doesn't work for me.

dpavlin@klin:/klin/Tegra/linux$ grep 'TEGRA.*UART' .config
# CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA is not set
CONFIG_TEGRA_DEBUG_UARTA=y
# CONFIG_TEGRA_DEBUG_UARTB is not set
# CONFIG_TEGRA_DEBUG_UARTC is not set
# CONFIG_TEGRA_DEBUG_UARTD is not set
# CONFIG_TEGRA_DEBUG_UARTE is not set
CONFIG_DEBUG_TEGRA_UART=y

serial port

https://ac100.grandou.net/serial_port_modification

The serial port is the JP1 connector, near the left speaker connector. Pinout, from right to left:

1 - in - RX UART1
2 - out - TX UART1
3 - out - T20_WAKE#
4 - out - +3V
5 - out - +1.8V
6
7
8 - in - SYSTEM_RESET#
9 - in - EC_TX80_PDATA
10 - in - GND

I decided to solder GND to outer pin of connector to the right of pin 1 as opposed to other side of connector.

After that, a peace of capton tape was put over solder connectors to somewhat re-enforce them and provide insulation
to keyboard cover.

Serial is 3.3V, 115200 8n1.

Output is:

dpavlin@nuc:/nuc/Tegra$ microcom -p /dev/ttyUSB2
connected to /dev/ttyUSB2
Escape character: Ctrl-\
Type the escape character to get to the prompt.

Error: invalid dtb and unrecognized/unsupported machine ID

Available machine support:

ID (hex)        NAME
ffffffff        Generic DT based system
ffffffff        NVIDIA Tegra SoC (Flattened Device Tree)

Please check your kernel config and/or bootloader.

According to http://billauer.co.il/blog/2014/02/uboot-linux-dtb-fdt-device-tree/ this means that kernel didn't found valid device tree and tries to detect board usin machine ID registrars.

Solution for this seems to use u-boot variables for loading kernel, ramfs and dtb as opposed to values which script creates,
so this works (loading from usb keychain):

fatload usb 0:1 ${kernel_addr_r} /boot/zImage
fatload usb 0:1 ${fdt_addr_r} /boot/tegra20-paz00.dtb
fatload usb 0:1 ${ramdisk_addr_r} /boot/uInitrd.new
bootz ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}

Here are also known working addresses which u-boot uses:

Tegra20 (Paz00) MOD # echo ${kernel_addr_r}
0x01000000
Tegra20 (Paz00) MOD # echo ${fdt_addr_r}
0x02000000
Tegra20 (Paz00) MOD # echo ${ramdisk_addr_r} 
0x02100000

so much higher in memory map than create_image script. However, u-boot seems to want to load at 0x108000 so it's inpractical
to generate huge image to load kernel, dtb and initramfs at correct addresses.

CH340G serial

Some of those serial dongles (I have one which is intended for esp01) have been configured for 5V operation instead of 3.3V.

You can check that by measuring RX and TX while plugged in in USB and if they are more than 3.3V your dongle is not really
3.3V.

newer(ish) version is on https://github.com/dmitry-pervushin/usbboot-omap4

[17:54:53] *** (5/5) FLASHING TO DEVICE ***
[17:54:53] Run the following to flash your installation to the target device:
[17:54:53] * pmbootstrap flasher flash_rootfs
[17:54:53]   Flashes the generated rootfs image to your device:
[17:54:53]   /nuc/pmbootstrap-work/chroot_native/home/pmos/rootfs/samsung-maguro.img
[17:54:53]   (NOTE: This file has a partition table, which contains /boot and / subpartitions. That way we don't need to change the partition layout on your device.)
[17:54:53] * pmbootstrap flasher flash_kernel
[17:54:53]   Flashes the kernel + initramfs to your device:
[17:54:53]   /nuc/pmbootstrap-work/chroot_rootfs_samsung-maguro/boot
[17:54:53]   (NOTE: fastboot also supports booting the kernel/initramfs directly without flashing. Use 'pmbootstrap flasher boot' to do that.)
[17:54:53] * If the above steps do not work, you can also create symlinks to the generated files with 'pmbootstrap export' and flash outside of pmbootstrap.
[17:54:53] NOTE: chroot is still active (use 'pmbootstrap shutdown' as necessary)
[17:54:53] Done
